2005-10-28[ARM] 4/4 Combine oprofile common and init codeRussell King
There is nothing special about having the init code separate from the common code, so combine the two. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-10-28[ARM] 3/4 Rename common oprofile codeRussell King
The common oprofile code assumes the name "PMU" (from Intel's performance management unit). This is misleading when we start adding oprofile support for other machine types which don't use the same terminology. Call it op_arm_* instead of pmu_*. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-10-28[ARM] 2/4 Fix oprofile suspend/resumeRussell King
The oprofile suspend/resume was missing locking. If we failed to start oprofile on resume, we still reported that it was enabled. Instead, disable oprofile on error. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-10-28[ARM] Re-jig bootmem initialisationRussell King
Make ARM independent of the way bootmem operates internally. We now map each node as we initialise it, and place the bootmem bitmap inside each node, rather than all in the first node. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2005-10-28[ARM] 2/4: Remove asm/hardware.h from asm-arm/arch-ebsa110/io.hRussell King

2005-10-26[PATCH] ppc64: Fix wrong register mapping in mpic driverBenjamin Herrenschmidt
The mpic interrupt controller driver (used on G5 and early pSeries among others) has a bug where it doesn't get the right virtual address for the timer registers. It causes the driver to poke at the MMIO space of whatever has been mapped just next to it (ouch !) when initializing and causes boot failures on some IBM machines.

2005-10-21[PARISC] Properly specify section alignment for real2.SGrant Grundler
.align applies to the current section - ie section directives come first. Thanks to Joel Soete for catching this. Signed-off-by: Grant Grundler <grundler@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
2005-10-21[PARISC] Specify level to fix binutils level promotion bugGrant Grundler
fixup.S needs to specify .level and use correct LDREG macro. New binutils has a bug where it doesn't "promote" from PA1.0 to PA1.1 correctly when using ",s" completer. remove use of __LP64__ in assembly.h and add some white space.

2005-10-21[PARISC] Explicitly specify sr4 when flushing kernel spaceMatthew Wilcox
Specify sr4 when flushing kernel space (we could equally well use sr5-7, but must not use sr0). Signed-off-by: Matthew Wilcox <willy@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
2005-10-21[PARISC] Properly specify index field to I/D cache flush opsGrant Grundler
replace use of "0" with "%r0" since PA 1.1 I/D flush ops only take a general register and not an immediate value for the index field. This just forces the code to always be PA 1.1 "clean".

2005-10-21[PARISC] Fix copy_user_page_asm to NOT access past end of pageGrant Grundler
2.6.12-rc2-pa3 fix copy_user_page_asm to NOT access past end of page. My bad. /o\ Lamont confirmed that instructions following a conditional branch are *alway* executed regardless if the branch is taken or not. Unless they are nullified (which was missing in this case). He also noted: Conditional branches nullify on forward taken branch, and on non-taken backward branch. Note that .+4 is a backwards branch. This makes alot more sense than the giberish in the PA20 arch book. Compiles and boots on both 64-bit (a500) and 32-bit (j6k).

2005-10-21[PARISC] Fix the alloc_slabmgmt panicJames Bottomley
Fix the alloc_slabmgmt panic Hopefully this should also fix a lot of other intermittent kernel bugs. The problem has been around since 2.6.9-rc2-pa6 when we allowed floating point registers to be used in kernel code. The essence of the problem is that gcc prefers to use floating point for integer divides and multiples. Further, it can rely on the values in the no clobber fp regs being correct across a function call. Unfortunately, our task switch function only saves the integer no clobber registers, not the fp ones, so if gcc makes a function call to any function in the kernel which could sleep, the values it is relying on in any no clobber floating point register may be lost. In the case of alloc_slabmgmt, the value of the page offset is being stored in %fr12 across a call to kmem_getpages(), which sleeps if no pages are available. Thus, the offset can be trashed and the slab code can end up with a completely bogus address leading to corruption. Kudos to Randolph who came up with the program to trip this problem at will and thus allowed it to be tracked and fixed.

2.6.12-rc1-pa6 use work queue in LED/LCD driver instead of tasklet. Main advantage is it allows use of msleep() in the led_LCD_driver to "atomically" perform two MMIO writes (CMD, then DATA).

Signed-off-by: Grant Grundler <grundler@parisc-linux.org> Take into account nullified insn and lock functions for profiling This is needed at the end of functions; it is typical that the return branch nullifies the next insn, which is in the next function.
