e6c667592e [PATCH] Fix x86_64/msr.h interface to agree with i386/msr.h
Ever since we remove msr.c from x86_64 branch and started grabbing it from
i386, msr device (read functionality) has been broken for us.

This is due to the differences between asm-i386/msr.h and asm-x86_64/msr.h interfaces.

Here is a patch to our side to fix this.

Thankfully, as of current (2.6.15-rc1-git6) tree, arch/i386/kernel/msr.c is the only file that uses rdmsr_safe macro.

pcibios_assign_all_busses now just refers to the pci_assign_all_buses

just 0 instead of a function that always returns 0 on 64-bit.

asm-ppc64/imalloc.h is only included from files in arch/powerpc/mm.
We already have a header for mm local definitions,
arch/powerpc/mm/mmu_decl.h.  Thus, this patch moves the contents of
imalloc.h into mmu_decl.h.  The only exception are the definitions of
PHBS_IO_BASE, IMALLOC_BASE and IMALLOC_END.  Those are moved into
pgtable.h, next to similar definitions of VMALLOC_START and
VMALLOC_SIZE.

Built for multiplatform 32bit and 64bit (ARCH=powerpc).

6defa38b37 powerpc: Fix delay functions for 601 processors
My earlier merge of delay.h introduced a timebase-based udelay for
32-bit machines but also broke the 601, which doesn't have the
timebase register.  This fixes it by using the 601's RTC register on
the 601, and also moves __delay() and udelay() to be out-of-line in
arch/powerpc/kernel/time.c.  These functions aren't really performance
critical, after all.

29a622dd2b [PARISC] Always spinlock tlb flush operations to ensure preempt safety

08dc2ca61e [PARISC] Fix our spinlock implementation
We actually have two separate bad bugs

1. The read_lock implementation spins with disabled interrupts.  This is
completely wrong
2. Our spin_lock_irqsave should check to see if interrupts were enabled
before the call and re-enable interrupts around the inner spin loop.

The problem is that if we spin with interrupts off, we can't receive
IPIs. This has resulted in a bug where SMP machines suddenly spit
smp_call_function timeout messages and hang.

The scenario I've caught is

CPU0 does a flush_tlb_all holding the vmlist_lock for write.
CPU1 tries a cat of /proc/meminfo which tries to acquire vmlist_lock for
     read
CPU1 is now spinning with interrupts disabled
CPU0 tries to execute a smp_call_function to flush the local tlb caches

This is now a deadlock because CPU1 is spinning with interrupts disabled
and can never receive the IPI

c2ab64d098 [PARISC] Add IRQ affinities
This really only adds them for the machines I can check SMP on, which
is CPU interrupts and IOSAPIC (so not any of the GSC based machines).

Unfortunately, irqbalanced is a bit x86 centric, so it doesn't do an
incredibly good job, but it does work.

Fix our interrupts not to use smp_call_function

On K and D class smp, the generic code calls this under an irq

The fix is to use a new scheme based on the IPI_NOP.

b7fd1edd2c [PATCH] x86: fix sigaddset() inline asm memory constraint
Due to incomplete memory constraints, gcc would miscompile code with
sigaddset on i386 if sig arg was const.

A quote form Jakub to make the issue clear:

 "You need either
	__asm__("btsl %1,%0" : "+m"(*set) : "Ir"(_sig-1) : "cc");
  or
	__asm__("btsl %1,%0" : "=m"(*set) : "Ir"(_sig-1), "m"(*set) : "cc");
  because the btsl instruction doesn't just set the memory to some
  value, but needs to read its previous content as well.  If you don't
  tell that fact to GCC, GCC is of course free to optimize as if the asm
  was just setting the value and not depended on the previous value."
