|

When page alloc debugging is not enabled, we essentially accept any
virtual address for linear kernel TLB misses. But with kgdb, kernel
address probing, and other facilities we can try to access arbitrary
crap.
So, make sure the address we miss on will translate to physical memory
that actually exists.
In order to make this work we have to embed the valid address bitmap
into the kernel image. And in order to make that less expensive we
make an adjustment, in that the max physical memory address is
decreased to "1 << 41", even on the chips that support a 42-bit
physical address space. We can do this because bit 41 indicates
"I/O space" and thus covers non-memory ranges.
The result of this is that:
1) kpte_linear_bitmap shrinks from 2K to 1K in size
2) we need 64K more for the valid address bitmap
We can't let the valid address bitmap be dynamically allocated
once we start using it to validate TLB misses, otherwise we have
crazy issues to deal with wrt. recursive TLB misses and such.
If we're in a TLB miss it could be the deepest trap level that's legal
inside of the cpu. So if we TLB miss referencing the bitmap, the cpu
will be out of trap levels and enter RED state.
To guard against out-of-range accesses to the bitmap, we have to check
to make sure no bits in the physical address above bit 40 are set. We
could export and use last_valid_pfn for this check, but that's just an
unnecessary extra memory reference.
On the plus side of all this, since we load all of these translations
into the special 4MB mapping TSB, and we check the TSB first for TLB
misses, there should be absolutely no real cost for these new checks
in the TLB miss path.

binutils prior to 2.17 can't deal with the currently possible
situation of a new segment following the per-CPU segment, but
that new segment being empty - objcopy misplaces the .bss (and
perhaps also the .brk) sections outside of any segment.
However, the current ordering of sections really just appears
to be the effect of cumulative unrelated changes; re-ordering
things allows to easily guarantee that the segment following
the per-CPU one is non-empty, and at once eliminates the need
for the bogus data.init2 segment.
Once touching this code, also use the various data section
helper macros from include/asm-generic/vmlinux.lds.h.

As noted in 83d349f35e1ae72268c5104dbf9ab2ae635425d4 ("x86: don't send
an IPI to the empty set of CPU's"), some APIC's will be very unhappy
with an empty destination mask. That commit added a WARN_ON() for that
case, and avoided the resulting problem, but didn't fix the underlying
reason for why those empty mask cases happened.
This fixes that, by checking the result of 'cpumask_andnot()' of the
current CPU actually has any other CPU's left in the set of CPU's to be
sent a TLB flush, and not calling down to the IPI code if the mask is
empty.
The reason this started happening at all is that we started passing just
the CPU mask pointers around in commit 4595f9620 ("x86: change
flush_tlb_others to take a const struct cpumask"), and when we did that,
the cpumask was no longer thread-local.
Before that commit, flush_tlb_mm() used to create it's own copy of
'mm->cpu_vm_mask' and pass that copy down to the low-level flush
routines after having tested that it was not empty. But after changing
it to just pass down the CPU mask pointer, the lower level TLB flush
routines would now get a pointer to that 'mm->cpu_vm_mask', and that
could still change - and become empty - after the test due to other
CPU's having flushed their own TLB's.
See
http://bugzilla.kernel.org/show_bug.cgi?id=13933
for details.

The default_send_IPI_mask_logical() function uses the "flat" APIC mode
to send an IPI to a set of CPU's at once, but if that set happens to be
empty, some older local APIC's will apparently be rather unhappy. So
just warn if a caller gives us an empty mask, and ignore it.
This fixes a regression in 2.6.30.x, due to commit 4595f9620 ("x86:
change flush_tlb_others to take a const struct cpumask"), documented
here:
http://bugzilla.kernel.org/show_bug.cgi?id=13933
which causes a silent lock-up. It only seems to happen on PPro, P2, P3
and Athlon XP cores. Most developers sadly (or not so sadly, if you're
a developer..) have more modern CPU's. Also, on x86-64 we don't use the
flat APIC mode, so it would never trigger there even if the APIC didn't
like sending an empty IPI mask.

Currently clockevents_notify() is called with interrupts enabled at
some places and interrupts disabled at some other places.
This results in a deadlock in this scenario.
cpu A holds clockevents_lock in clockevents_notify() with irqs enabled
cpu B waits for clockevents_lock in clockevents_notify() with irqs disabled
cpu C doing set_mtrr() which will try to rendezvous of all the cpus.
This will result in C and A come to the rendezvous point and waiting
for B. B is stuck forever waiting for the spinlock and thus not
reaching the rendezvous point.
Fix the clockevents code so that clockevents_lock is taken with
interrupts disabled and thus avoid the above deadlock.
Also call lapic_timer_propagate_broadcast() on the destination cpu so
that we avoid calling smp_call_function() in the clockevents notifier
chain.
This issue left us wondering if we need to change the MTRR rendezvous
logic to use stop machine logic (instead of smp_call_function) or add
a check in spinlock debug code to see if there are other spinlocks
which gets taken under both interrupts enabled/disabled conditions.

Normally, srmmu uses different trap table register values to allow
determination of the cpu we're on. All of the trap tables have
identical content, they just sit at different offsets from the first
trap table, and the offset shifted down and masked out determines
the cpu we are on.
The code tries to free them up when they aren't actually used
(don't have all 4 cpus, we're on sun4d, etc.) but that causes
problems.
For one thing it triggers false positives in the DMA debugging
code. And fixing that up while preserving this relative offset
thing isn't trivial.
So just kill the freeing code, it costs us at most 3 pages, big
deal...

I think arch/sparc/kernel/sys32.S has an incorrect splice definition:
SIGN2(sys32_splice, sys_splice, %o0, %o1)
The splice() prototype looks like :
long splice(int fd_in, loff_t *off_in, int fd_out,
loff_t *off_out, size_t len, unsigned int flags);
So I think we should have :
SIGN2(sys32_splice, sys_splice, %o0, %o2)

Commit 0e83815be719d3391bf5ea24b7fe696c07dbd417 changed the
section the initial_code variable gets allocated in, in an
attempt to address a section conflict warning. This, however
created a new section conflict when building without

this is to always use __REFDATA.
Once at it, also fix a second section mismatch when not using

For noMMU system when you use larger rootfs image
there is problem with using _end label because
we increase klimit but in memory initialization
we use still _end which is wrong. Larger mtd rootfs

MMU kernel use static initialization where klimit
is setup to _end. There is no any other hanling

PAT code maps the ISA memory range as WB in the PAT attribute, so that
fixed range MTRR registers define the actual memory type (UC/WC/WT etc).
But the upper level is_new_memtype_allowed() API checks are failing,
as the request here is for UC and the return tracked type is WB (Tracked type is
WB as MTRR type for this legacy range potentially will be different for each
4k page).
Fix is_new_memtype_allowed() by always succeeding the ISA address range
checks, as the null PAT (WB) and def MTRR fixed range register settings
satisfy the memory type needs of the applications that map the ISA address
range.

An older test-box started hanging at the following point during

[ 0.028995] mce: CPU supports 5 MCE banks
I've bisected it down to commit 4efc0670 ("x86, mce: use 64bit
machine check code on 32bit"), which utilizes the MCE code on
32-bit systems too.
The problem is caused by this detail in my config:
# CONFIG_CPU_SUP_INTEL is not set
This disables the quirks in mce_cpu_quirks() but still enables
MCE support - which then hangs due to the missing quirk
workaround needed on this CPU:
if (c->x86 == 6 && c->x86_model < 0x1A && banks > 0)
mce_banks[0].init = 0;
The safe solution is to not initialize MCEs if we dont know on
what CPU we are running (or if that CPU's support code got
disabled in the config).
Also be a bit more defensive on 32-bit systems: dont do a
boot-time dump of pending MCEs not just on the specific system
that we found a problem with (Pentium-M), but earlier ones as
well.
Now this problem is probably not common and disabling CPU
support is rare - but still being more defensive in something
we turned on for a wide range of CPUs is prudent.

lockdep support) don't log boot MCEs on Pentium M (model == 13) CPUs
by default ("mce=bootlog" boot parameter can be be used to get the old
behavior).

The function uv_acpi_madt_oem_check() has been marked __init,
the struct apic_x2apic_uv_x has been marked __refdata.
The aim is to address the following section mismatch messages:
WARNING: arch/x86/kernel/apic/built-in.o(.data+0x1368): Section mismatch in reference from the variable apic_x2apic_uv_x to the function .cpuinit.text:uv_wakeup_secondary()
The variable apic_x2apic_uv_x references
the function __cpuinit uv_wakeup_secondary()
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console,
WARNING: arch/x86/kernel/built-in.o(.data+0x68e8): Section mismatch in reference from the variable apic_x2apic_uv_x to the function .cpuinit.text:uv_wakeup_secondary()
The variable apic_x2apic_uv_x references
the function __cpuinit uv_wakeup_secondary()
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console,
WARNING: arch/x86/built-in.o(.text+0x7b36f): Section mismatch in reference from the function uv_acpi_madt_oem_check() to the function .init.text:early_ioremap()
The function uv_acpi_madt_oem_check() references
the function __init early_ioremap().
This is often because uv_acpi_madt_oem_check lacks a __init
annotation or the annotation of early_ioremap is wrong.
WARNING: arch/x86/built-in.o(.text+0x7b38d): Section mismatch in reference from the function uv_acpi_madt_oem_check() to the function .init.text:early_iounmap()
The function uv_acpi_madt_oem_check() references
the function __init early_iounmap().
This is often because uv_acpi_madt_oem_check lacks a __init
annotation or the annotation of early_iounmap is wrong.

0d01f31439c1e4d602bf9fdc924ab66f407f5e38 "x86, mce: therm_throt
- change when we print messages" removed redundant
announcements of "Temperature/speed normal".
They're not worth logging and remove their accompanying
"Machine check events logged" messages as well from the
console.

The u300_init_check_chip() function was not properly tagged with
the __init macro and provided a initsection mismatch on
compilation.
