- *
- * Revision 1.3  2002/05/28 16:16:07  johana
- * Handle empty fast_timer_list
- *
- * Revision 1.2  2002/05/27 15:38:42  johana
- * Made it compile without warnings on Linux 2.4.
- * (includes, wait_queue, PROC_FS and snprintf)
- *
- * Revision 1.1  2002/05/27 15:32:25  johana
- * arch/etrax100/kernel/fasttimer.c v1.8 from the elinux tree.
- *
- * Revision 1.8  2001/11/27 13:50:40  pkj
- * Disable interrupts while stopping the timer and while modifying the
- * list of active timers in timer1_handler() as it may be interrupted
- * by other interrupts (e.g., the serial interrupt) which may add fast
- * timers.
- *
- * Revision 1.7  2001/11/22 11:50:32  pkj
- * * Only store information about the last 16 timers.
- * * proc_fasttimer_read() now uses an allocated buffer, since it
- *   requires more space than just a page even for only writing the
- *   last 16 timers. The buffer is only allocated on request, so
- *   unless /proc/fasttimer is read, it is never allocated.
- * * Renamed fast_timer_started to fast_timers_started to match
- *   fast_timers_added and fast_timers_expired.
- * * Some clean-up.
- *
- * Revision 1.6  2000/12/13 14:02:08  johana
- * Removed volatile for fast_timer_list
- *
- * Revision 1.5  2000/12/13 13:55:35  johana
- * Added DEBUG_LOG, added som cli() and cleanup
- *
- * Revision 1.4  2000/12/05 13:48:50  johana
- * Added range check when writing proc file, modified timer int handling
- *
- * Revision 1.3  2000/11/23 10:10:20  johana
- * More debug/logging possibilities.
- * Moved GET_JIFFIES_USEC() to timex.h and time.c
- *
- * Revision 1.2  2000/11/01 13:41:04  johana
- * Clean up and bugfixes.
- * Created new do_gettimeofday_fast() that gets a timeval struct
- * with time based on jiffies and *R_TIMER0_DATA, uses a table
- * for fast conversion of timer value to microseconds.
- * (Much faster the standard do_gettimeofday() and we don't really
- * wan't to use the true time - we wan't the "uptime" so timers don't screw up
- * when we change the time.
- * TODO: Add efficient support for continuous timers as well.
- *
- * Revision 1.1  2000/10/26 15:49:16  johana
- * Added fasttimer, highresolution timers.

+/* TRUNCATED DIVISION BY SMALL INTEGERS
+
+   We are interested in q(x) = floor(x/y), where x >= 0 and y > 0
+   (with y fixed).
+
+   Let a = floor(z/y), for some choice of z.  Note that z will be
+   chosen so that division by z is cheap.
+
+   Let r be the remainder(z/y).  In other words, r = z - ay.
+
+   Now, our method is to choose a value for b such that
+
+   q'(x) = floor((ax+b)/z)
+
+   is equal to q(x) over as large a range of x as possible.  If the
+   two are equal over a sufficiently large range, and if it is easy to
+   form the product (ax), and it is easy to divide by z, then we can
+   perform the division much faster than the general division algorithm.
+
+   So, we want the following to be true:
+
+   .	For x in the following range:
+   .
+   .	    ky <= x < (k+1)y
+   .
+   .	implies that
+   .
+   .	    k <= (ax+b)/z < (k+1)
+
+   We want to determine b such that this is true for all k in the
+   range {0..K} for some maximum K.
+
+   Since (ax+b) is an increasing function of x, we can take each
+   bound separately to determine the "best" value for b.
+
+   (ax+b)/z < (k+1)	       implies
+
+   (a((k+1)y-1)+b < (k+1)z     implies
+
+   b < a + (k+1)(z-ay)	       implies
+
+   b < a + (k+1)r
+
+   This needs to be true for all k in the range {0..K}.  In
+   particular, it is true for k = 0 and this leads to a maximum
+   acceptable value for b.
+
+   b < a+r   or   b <= a+r-1
+
+   Taking the other bound, we have
+
+   k <= (ax+b)/z	       implies
+
+   k <= (aky+b)/z	       implies
+
+   k(z-ay) <= b		       implies
+
+   kr <= b
+
+   Clearly, the largest range for k will be achieved by maximizing b,
+   when r is not zero.	When r is zero, then the simplest choice for b
+   is 0.  When r is not 0, set
+
+   .	b = a+r-1
+
+   Now, by construction, q'(x) = floor((ax+b)/z) = q(x) = floor(x/y)
+   for all x in the range:
+
+   .	0 <= x < (K+1)y
+
+   We need to determine what K is.  Of our two bounds,
+
+   .	b < a+(k+1)r	is satisfied for all k >= 0, by construction.
+
+   The other bound is
+
+   .	kr <= b
+
+   This is always true if r = 0.  If r is not 0 (the usual case), then
+   K = floor((a+r-1)/r), is the maximum value for k.
+
+   Therefore, the formula q'(x) = floor((ax+b)/z) yields the correct
+   answer for q(x) = floor(x/y) when x is in the range
+
+   (0,(K+1)y-1)	       K = floor((a+r-1)/r)
+
+   To be most useful, we want (K+1)y-1 = (max x) >= 2**32-1 so that
+   the formula for q'(x) yields the correct value of q(x) for all x
+   representable by a single word in HPPA.
+
+   We are also constrained in that computing the product (ax), adding
+   b, and dividing by z must all be done quickly, otherwise we will be
+   better off going through the general algorithm using the DS
+   instruction, which uses approximately 70 cycles.
+
+   For each y, there is a choice of z which satisfies the constraints
+   for (K+1)y >= 2**32.  We may not, however, be able to satisfy the
+   timing constraints for arbitrary y.	It seems that z being equal to
+   a power of 2 or a power of 2 minus 1 is as good as we can do, since
+   it minimizes the time to do division by z.  We want the choice of z
+   to also result in a value for (a) that minimizes the computation of
+   the product (ax).  This is best achieved if (a) has a regular bit
+   pattern (so the multiplication can be done with shifts and adds).
+   The value of (a) also needs to be less than 2**32 so the product is
+   always guaranteed to fit in 2 words.
+
+   In actual practice, the following should be done:
+
+   1) For negative x, you should take the absolute value and remember
+   .  the fact so that the result can be negated.  This obviously does
+   .  not apply in the unsigned case.
+   2) For even y, you should factor out the power of 2 that divides y
+   .  and divide x by it.  You can then proceed by dividing by the
+   .  odd factor of y.
+
+   Here is a table of some odd values of y, and corresponding choices
+   for z which are "good".
+
+    y	  z	  r	 a (hex)     max x (hex)
+
+    3	2**32	  1	55555555      100000001
+    5	2**32	  1	33333333      100000003
+    7  2**24-1	  0	  249249     (infinite)
+    9  2**24-1	  0	  1c71c7     (infinite)
+   11  2**20-1	  0	   1745d     (infinite)
+   13  2**24-1	  0	  13b13b     (infinite)
+   15	2**32	  1	11111111      10000000d
+   17	2**32	  1	 f0f0f0f      10000000f
+
+   If r is 1, then b = a+r-1 = a.  This simplifies the computation
+   of (ax+b), since you can compute (x+1)(a) instead.  If r is 0,
+   then b = 0 is ok to use which simplifies (ax+b).
+
+   The bit patterns for 55555555, 33333333, and 11111111 are obviously
+   very regular.  The bit patterns for the other values of a above are:
+
+    y	   (hex)	  (binary)
+
+    7	  249249  001001001001001001001001  << regular >>
+    9	  1c71c7  000111000111000111000111  << regular >>
+   11	   1745d  000000010111010001011101  << irregular >>
+   13	  13b13b  000100111011000100111011  << irregular >>
+
+   The bit patterns for (a) corresponding to (y) of 11 and 13 may be
+   too irregular to warrant using this method.
+
+   When z is a power of 2 minus 1, then the division by z is slightly
+   more complicated, involving an iterative solution.
+
+   The code presented here solves division by 1 through 17, except for
+   11 and 13. There are algorithms for both signed and unsigned
+   quantities given.

+
+   Now, the algorithm for 7, 9, and 14 is an iterative one.  That is,
+   a loop body is executed until the tentative quotient is 0.  The
+   number of times the loop body is executed varies depending on the
+   dividend, but is never more than two times.	If the dividend is
+   less than the divisor, then the loop body is not executed at all.
+   Each iteration adds 4 cycles to the timings.

+   z = 2**24-1
+   r = z mod x = 0
+
+   so choose b = 0
+
+   Also, in order to divide by z = 2**24-1, we approximate by dividing
+   by (z+1) = 2**24 (which is easy), and then correcting.
+
+   (ax) = (z+1)q' + r
+   .	= zq' + (q'+r)
+
+   So to compute (ax)/z, compute q' = (ax)/(z+1) and r = (ax) mod (z+1)
+   Then the true remainder of (ax)/z is (q'+r).  Repeat the process
+   with this new remainder, adding the tentative quotients together,
+   until a tentative quotient is 0 (and then we are done).  There is
+   one last correction to be done.  It is possible that (q'+r) = z.
+   If so, then (q'+r)/(z+1) = 0 and it looks like we are done.	But,
+   in fact, we need to add 1 more to the quotient.  Now, it turns
+   out that this happens if and only if the original value x is
+   an exact multiple of y.  So, to avoid a three instruction test at
+   the end, instead use 1 instruction to add 1 to x at the beginning.  */

+
+/* TRUNCATED DIVISION BY SMALL INTEGERS
+
+   We are interested in q(x) = floor(x/y), where x >= 0 and y > 0
+   (with y fixed).
+
+   Let a = floor(z/y), for some choice of z.  Note that z will be
+   chosen so that division by z is cheap.
+
+   Let r be the remainder(z/y).  In other words, r = z - ay.
+
+   Now, our method is to choose a value for b such that
+
+   q'(x) = floor((ax+b)/z)
+
+   is equal to q(x) over as large a range of x as possible.  If the
+   two are equal over a sufficiently large range, and if it is easy to
+   form the product (ax), and it is easy to divide by z, then we can
+   perform the division much faster than the general division algorithm.
+
+   So, we want the following to be true:
+
+   .	For x in the following range:
+   .
+   .	    ky <= x < (k+1)y
+   .
+   .	implies that
+   .
+   .	    k <= (ax+b)/z < (k+1)
+
+   We want to determine b such that this is true for all k in the
+   range {0..K} for some maximum K.
+
+   Since (ax+b) is an increasing function of x, we can take each
+   bound separately to determine the "best" value for b.
+
+   (ax+b)/z < (k+1)	       implies
+
+   (a((k+1)y-1)+b < (k+1)z     implies
+
+   b < a + (k+1)(z-ay)	       implies
+
+   b < a + (k+1)r
+
+   This needs to be true for all k in the range {0..K}.  In
+   particular, it is true for k = 0 and this leads to a maximum
+   acceptable value for b.
+
+   b < a+r   or   b <= a+r-1
+
+   Taking the other bound, we have
+
+   k <= (ax+b)/z	       implies
+
+   k <= (aky+b)/z	       implies
+
+   k(z-ay) <= b		       implies
+
+   kr <= b
+
+   Clearly, the largest range for k will be achieved by maximizing b,
+   when r is not zero.	When r is zero, then the simplest choice for b
+   is 0.  When r is not 0, set
+
+   .	b = a+r-1
+
+   Now, by construction, q'(x) = floor((ax+b)/z) = q(x) = floor(x/y)
+   for all x in the range:
+
+   .	0 <= x < (K+1)y
+
+   We need to determine what K is.  Of our two bounds,
+
+   .	b < a+(k+1)r	is satisfied for all k >= 0, by construction.
+
+   The other bound is
+
+   .	kr <= b
+
+   This is always true if r = 0.  If r is not 0 (the usual case), then
+   K = floor((a+r-1)/r), is the maximum value for k.
+
+   Therefore, the formula q'(x) = floor((ax+b)/z) yields the correct
+   answer for q(x) = floor(x/y) when x is in the range
+
+   (0,(K+1)y-1)	       K = floor((a+r-1)/r)
+
+   To be most useful, we want (K+1)y-1 = (max x) >= 2**32-1 so that
+   the formula for q'(x) yields the correct value of q(x) for all x
+   representable by a single word in HPPA.
+
+   We are also constrained in that computing the product (ax), adding
+   b, and dividing by z must all be done quickly, otherwise we will be
+   better off going through the general algorithm using the DS
+   instruction, which uses approximately 70 cycles.
+
+   For each y, there is a choice of z which satisfies the constraints
+   for (K+1)y >= 2**32.  We may not, however, be able to satisfy the
+   timing constraints for arbitrary y.	It seems that z being equal to
+   a power of 2 or a power of 2 minus 1 is as good as we can do, since
+   it minimizes the time to do division by z.  We want the choice of z
+   to also result in a value for (a) that minimizes the computation of
+   the product (ax).  This is best achieved if (a) has a regular bit
+   pattern (so the multiplication can be done with shifts and adds).
+   The value of (a) also needs to be less than 2**32 so the product is
+   always guaranteed to fit in 2 words.
+
+   In actual practice, the following should be done:
+
+   1) For negative x, you should take the absolute value and remember
+   .  the fact so that the result can be negated.  This obviously does
+   .  not apply in the unsigned case.
+   2) For even y, you should factor out the power of 2 that divides y
+   .  and divide x by it.  You can then proceed by dividing by the
+   .  odd factor of y.
+
+   Here is a table of some odd values of y, and corresponding choices
+   for z which are "good".
+
+    y	  z	  r	 a (hex)     max x (hex)
+
+    3	2**32	  1	55555555      100000001
+    5	2**32	  1	33333333      100000003
+    7  2**24-1	  0	  249249     (infinite)
+    9  2**24-1	  0	  1c71c7     (infinite)
+   11  2**20-1	  0	   1745d     (infinite)
+   13  2**24-1	  0	  13b13b     (infinite)
+   15	2**32	  1	11111111      10000000d
+   17	2**32	  1	 f0f0f0f      10000000f
+
+   If r is 1, then b = a+r-1 = a.  This simplifies the computation
+   of (ax+b), since you can compute (x+1)(a) instead.  If r is 0,
+   then b = 0 is ok to use which simplifies (ax+b).
+
+   The bit patterns for 55555555, 33333333, and 11111111 are obviously
+   very regular.  The bit patterns for the other values of a above are:
+
+    y	   (hex)	  (binary)
+

+
+   The bit patterns for (a) corresponding to (y) of 11 and 13 may be
+   too irregular to warrant using this method.
+
+   When z is a power of 2 minus 1, then the division by z is slightly
+   more complicated, involving an iterative solution.
+
+   The code presented here solves division by 1 through 17, except for
+   11 and 13. There are algorithms for both signed and unsigned
+   quantities given.

+
+   Now, the algorithm for 7, 9, and 14 is an iterative one.  That is,
+   a loop body is executed until the tentative quotient is 0.  The
+   number of times the loop body is executed varies depending on the
+   dividend, but is never more than two times.	If the dividend is
+   less than the divisor, then the loop body is not executed at all.
+   Each iteration adds 4 cycles to the timings.

+   z = 2**24-1
+   r = z mod x = 0
+
+   so choose b = 0
+
+   Also, in order to divide by z = 2**24-1, we approximate by dividing

+
+   (ax) = (z+1)q' + r
+   .	= zq' + (q'+r)
+
+   So to compute (ax)/z, compute q' = (ax)/(z+1) and r = (ax) mod (z+1)
+   Then the true remainder of (ax)/z is (q'+r).  Repeat the process
+   with this new remainder, adding the tentative quotients together,
+   until a tentative quotient is 0 (and then we are done).  There is
+   one last correction to be done.  It is possible that (q'+r) = z.
+   If so, then (q'+r)/(z+1) = 0 and it looks like we are done.	But,
+   in fact, we need to add 1 more to the quotient.  Now, it turns
+   out that this happens if and only if the original value x is
+   an exact multiple of y.  So, to avoid a three instruction test at

+ * A hypervisor allows multiple Operating Systems to run on a single machine.
+ * To quote David Wheeler: "Any problem in computer science can be solved with
+ * another layer of indirection."
+ *
+ * We keep things simple in two ways.  First, we start with a normal Linux
+ * kernel and insert a module (lg.ko) which allows us to run other Linux
+ * kernels the same way we'd run processes.  We call the first kernel the Host,
+ * and the others the Guests.  The program which sets up and configures Guests
+ * (such as the example in Documentation/lguest/lguest.c) is called the
+ * Launcher.
+ *
+ * Secondly, we only run specially modified Guests, not normal kernels.  When
+ * you set CONFIG_LGUEST to 'y' or 'm', this automatically sets
+ * CONFIG_LGUEST_GUEST=y, which compiles this file into the kernel so it knows
+ * how to be a Guest.  This means that you can use the same kernel you boot
+ * normally (ie. as a Host) as a Guest.
+ *
+ * These Guests know that they cannot do privileged operations, such as disable
+ * interrupts, and that they have to ask the Host to do such things explicitly.
+ * This file consists of all the replacements for such low-level native
+ * hardware operations: these special Guest versions call the Host.
+ *
+ * So how does the kernel know it's a Guest?  The Guest starts at a special
+ * entry point marked with a magic string, which sets up a few things then
+ * calls here.  We replace the native functions various "paravirt" structures
+ * with our Guest versions, then boot like normal. :*/

+ * Page Table Handling.
+ *
+ * Now would be a good time to take a rest and grab a coffee or similarly
+ * relaxing stimulant.  The easy parts are behind us, and the trek gradually
+ * winds uphill from here.
+ *
+ * Quick refresher: memory is divided into "pages" of 4096 bytes each.  The CPU
+ * maps virtual addresses to physical addresses using "page tables".  We could
+ * use one huge index of 1 million entries: each address is 4 bytes, so that's
+ * 1024 pages just to hold the page tables.   But since most virtual addresses
+ * are unused, we use a two level index which saves space.  The cr3 register
+ * contains the physical address of the top level "page directory" page, which
+ * contains physical addresses of up to 1024 second-level pages.  Each of these
+ * second level pages contains up to 1024 physical addresses of actual pages,
+ * or Page Table Entries (PTEs).
+ *
+ * Here's a diagram, where arrows indicate physical addresses:
+ *
+ * cr3 ---> +---------+
+ *	    |  	   --------->+---------+
+ *	    |	      |	     | PADDR1  |
+ *	  Top-level   |	     | PADDR2  |
+ *	  (PMD) page  |	     | 	       |
+ *	    |	      |	   Lower-level |
+ *	    |	      |	   (PTE) page  |
+ *	    |	      |	     |	       |
+ *	      ....    	     	 ....
+ *
+ * So to convert a virtual address to a physical address, we look up the top
+ * level, which points us to the second level, which gives us the physical
+ * address of that page.  If the top level entry was not present, or the second
+ * level entry was not present, then the virtual address is invalid (we
+ * say "the page was not mapped").
+ *
+ * Put another way, a 32-bit virtual address is divided up like so:
+ *
+ *  1 1 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
+ * |<---- 10 bits ---->|<---- 10 bits ---->|<------ 12 bits ------>|
+ *    Index into top     Index into second      Offset within page
+ *  page directory page    pagetable page
+ *
+ * The kernel spends a lot of time changing both the top-level page directory
+ * and lower-level pagetable pages.  The Guest doesn't know physical addresses,
+ * so while it maintains these page tables exactly like normal, it also needs
+ * to keep the Host informed whenever it makes a change: the Host will create
+ * the real page tables based on the Guests'.

+ * The "iret" instruction is used to return from an interrupt or trap.  The
+ * stack looks like this:
+ *   old address
+ *   old code segment & privilege level
+ *   old processor flags ("eflags")
+ *
+ * The "iret" instruction pops those values off the stack and restores them all
+ * at once.  The only problem is that eflags includes the Interrupt Flag which
+ * the Guest can't change: the CPU will simply ignore it when we do an "iret".
+ * So we have to copy eflags from the stack to lguest_data.irq_enabled before
+ * we do the "iret".
+ *
+ * There are two problems with this: firstly, we need to use a register to do
+ * the copy and secondly, the whole thing needs to be atomic.  The first
+ * problem is easy to solve: push %eax on the stack so we can use it, and then
+ * restore it at the end just before the real "iret".
+ *
+ * The second is harder: copying eflags to lguest_data.irq_enabled will turn
+ * interrupts on before we're finished, so we could be interrupted before we
+ * return to userspace or wherever.  Our solution to this is to surround the
+ * code with lguest_noirq_start: and lguest_noirq_end: labels.  We tell the

-	  processor access to memory ranges. This is most useful if you have
-	  a video (VGA) card on a PCI or AGP bus. Enabling write-combining

-	  before bursting over the PCI/AGP bus. This can increase performance
-	  of image write operations 2.5 times or more. Saying Y here creates a
-	  /proc/mtrr file which may be used to manipulate your processor's
-	  MTRRs. Typically the X server should use this.
-
-	  This code has a reasonably generic interface so that similar
-	  control registers on other processors can be easily supported
-	  as well.
-
-	  Saying Y here also fixes a problem with buggy SMP BIOSes which only
-	  set the MTRRs for the boot CPU and not for the secondary CPUs. This
-	  can lead to all sorts of problems, so it's good to say Y here.

-
-config KEXEC
-	bool "kexec system call"
-	help
-	  kexec is a system call that implements the ability to shutdown your
-	  current kernel, and to start another kernel.  It is like a reboot
-	  but it is independent of the system firmware.   And like a reboot
-	  you can start any kernel with it, not just Linux.
-
-	  The name comes from the similarity to the exec system call.
-
-	  It is an ongoing process to be certain the hardware in a machine
-	  is properly shutdown, so do not be surprised if this code does not
-	  initially work for you.  It may help to enable device hotplugging
-	  support.  As of this writing the exact hardware interface is
-	  strongly in flux, so no good recommendation can be made.
-
-config CRASH_DUMP
-	bool "kernel crash dumps (EXPERIMENTAL)"
-	depends on EXPERIMENTAL
-	help
-          Generate crash dump after being started by kexec.
-          This should be normally only set in special crash dump kernels
-          which are loaded in the main kernel with kexec-tools into
-          a specially reserved region and then later executed after
-          a crash by kdump/kexec. The crash dump kernel must be compiled
-	  to a memory address not used by the main kernel or BIOS using
-	  PHYSICAL_START.
-          For more details see Documentation/kdump/kdump.txt
-
-config RELOCATABLE
-	bool "Build a relocatable kernel(EXPERIMENTAL)"
-	depends on EXPERIMENTAL
-	help
-	  Builds a relocatable kernel. This enables loading and running
-	  a kernel binary from a different physical address than it has
-	  been compiled for.
-
-	  One use is for the kexec on panic case where the recovery kernel
-	  must live at a different physical address than the primary
-	  kernel.
-
-	  Note: If CONFIG_RELOCATABLE=y, then kernel run from the address
-	  it has been loaded at and compile time physical address
-	  (CONFIG_PHYSICAL_START) is ignored.
-
-config PHYSICAL_START
-	hex "Physical address where the kernel is loaded" if (EMBEDDED || CRASH_DUMP)
-	default "0x200000"
-	help
-	  This gives the physical address where the kernel is loaded. It
-	  should be aligned to 2MB boundary.
-
-	  If kernel is a not relocatable (CONFIG_RELOCATABLE=n) then
-	  bzImage will decompress itself to above physical address and
-	  run from there. Otherwise, bzImage will run from the address where
-	  it has been loaded by the boot loader and will ignore above physical
-	  address.
-
-	  In normal kdump cases one does not have to set/change this option
-	  as now bzImage can be compiled as a completely relocatable image
-	  (CONFIG_RELOCATABLE=y) and be used to load and run from a different
-	  address. This option is mainly useful for the folks who don't want
-	  to use a bzImage for capturing the crash dump and want to use a
-	  vmlinux instead.
-
-	  So if you are using bzImage for capturing the crash dump, leave
-	  the value here unchanged to 0x200000 and set CONFIG_RELOCATABLE=y.
-	  Otherwise if you plan to use vmlinux for capturing the crash dump
-	  change this value to start of the reserved region (Typically 16MB
-	  0x1000000). In other words, it can be set based on the "X" value as
-	  specified in the "crashkernel=YM@XM" command line boot parameter
-	  passed to the panic-ed kernel. Typically this parameter is set as
-	  crashkernel=64M@16M. Please take a look at
-	  Documentation/kdump/kdump.txt for more details about crash dumps.
-
-	  Usage of bzImage for capturing the crash dump is advantageous as
-	  one does not have to build two kernels. Same kernel can be used
-	  as production kernel and capture kernel.
-
-	  Don't change this unless you know what you are doing.
-
-config SECCOMP
-	bool "Enable seccomp to safely compute untrusted bytecode"
-	depends on PROC_FS
-	default y
-	help
-	  This kernel feature is useful for number crunching applications
-	  that may need to compute untrusted bytecode during their
-	  execution. By using pipes or other transports made available to
-	  the process as file descriptors supporting the read/write
-	  syscalls, it's possible to isolate those applications in
-	  their own address space using seccomp. Once seccomp is
-	  enabled via /proc/<pid>/seccomp, it cannot be disabled
-	  and the task is only allowed to execute a few safe syscalls
-	  defined by each seccomp mode.
-
-	  If unsure, say Y. Only embedded should say N here.
-
-config CC_STACKPROTECTOR
-	bool "Enable -fstack-protector buffer overflow detection (EXPERIMENTAL)"
-	depends on EXPERIMENTAL
-	help
-         This option turns on the -fstack-protector GCC feature. This
-	  feature puts, at the beginning of critical functions, a canary
-	  value on the stack just before the return address, and validates
-	  the value just before actually returning.  Stack based buffer
-	  overflows (that need to overwrite this return address) now also
-	  overwrite the canary, which gets detected and the attack is then
-	  neutralized via a kernel panic.
-
-	  This feature requires gcc version 4.2 or above, or a distribution
-	  gcc with the feature backported. Older versions are automatically
-	  detected and for those versions, this configuration option is ignored.
-
-config CC_STACKPROTECTOR_ALL
-	bool "Use stack-protector for all functions"
-	depends on CC_STACKPROTECTOR
-	help
-	  Normally, GCC only inserts the canary value protection for
-	  functions that use large-ish on-stack buffers. By enabling
-	  this option, GCC will be asked to do this for ALL functions.
