3d124cbba3 fix OOM killing processes wrongly thought MPOL_BIND
I only have CONFIG_NUMA=y for build testing: surprised when trying a memhog

fdc30b3d44 Fix possible NULL pointer access in 8250 serial driver
I encountered the following kernel panic.  The cause of this problem was
NULL pointer access in check_modem_status() in 8250.c.  I confirmed this
problem is fixed by the attached patch, but I don't know this is the
correct fix.

Fix the possible NULL pointer access in check_modem_status() in 8250.c.  The
check_modem_status() would access 'info' member of uart_port structure, but it
is not initialized before uart_open() is called.  The check_modem_status() can
be called through /proc/tty/driver/serial before uart_open() is called.

37f01d64d8 [POWERPC] Abolish PHYS_FMT macro from arch/powerpc
32-bit powerpc systems define a macro, PHYS_FMT, giving a printf
format string fragment for displaying physical addresses, since most
32-bit powerpc platforms use 32-bit physical addresses but a few use
64-bit physical addresses.

This macro is used in exactly one place, a rare error message, where
we can solve the problem more simply by just unconditionally casting
the address up to 64-bit quantity before formatting it.

This patch does so, meaning that as we bring MMU definitions from
asm-ppc over to asm-powerpc, cleaning them up in the process, we don't
need to implement this ugly macro (which additionally has a very bad
name for something global).

6210230725 [POWERPC] Cleanup and fix breakage in tlbflush.h
BenH's commit a741e67969 in powerpc.git,
although (AFAICT) only intended to affect ppc64, also has side-effects
which break 44x.  I think 40x, 8xx and Freescale Book E are also
affected, though I haven't tested them.

The problem lies in unconditionally removing flush_tlb_pending() from
the versions of flush_tlb_mm(), flush_tlb_range() and
flush_tlb_kernel_range() used on ppc64 - which are also used the
embedded platforms mentioned above.

The patch below cleans up the convoluted #ifdef logic in tlbflush.h,
in the process restoring the necessary flushes for the software TLB
platforms.  There are three sets of definitions for the flushing
hooks: the software TLB versions (revised to avoid using names which
appear to related to TLB batching), the 32-bit hash based versions
(external functions) amd the 64-bit hash based versions (which
implement batching).

It also moves the declaration of update_mmu_cache() to always be in
tlbflush.h (previously it was in tlbflush.h except for PPC64, where it
was in pgtable.h).

Booted on Ebony (440GP) and compiled for 64-bit and 32-bit
multiplatform.

f65573314e [POWERPC] Re-organize Kconfig code for 4xx in arch/powerpc
Now that we always take a device tree in arch/powerpc, there's no good
reason not to allow a single kernel to support multiple embedded 4xx
boards - the correct platform code can be selected based on the device
tree information.

Therefore, this patch re-arranges the 4xx Kconfig code to allow this.
In addition we:
	- use "select" instead of depends to configure the correct
	  config options for specific 4xx CPUs and workarounds, which
	  makes the information about specific boards and CPUs less
	  scattered.
	- Some old, unused (in arch/powerpc) config options are
	  removed: WANT_EARLY_SERIAL, IBM_OCP, etc.

9ce883becb [PATCH] x86: Remove noreplacement option
noreplacement is dangerous on modern systems because it will not replace the
context switch FNSAVE with SSE aware FXSAVE. But other places in the kernel still assume
SSE and do FXSAVE and the CPU will then access FXSAVE information with
FNSAVE and cause corruption.

Easiest way to avoid this is to remove the option. It was mostly for paranoia
reasons anyways and alternative()s have been stable for some time.

Thanks to Jeremy F. for reporting and helping debug it.

01abc2aa0f Revert "adjust legacy IDE resource setting (v2)"
This reverts commit ed8ccee091.

It causes hang on boot for some users and we don't yet know why:

http://bugzilla.kernel.org/show_bug.cgi?id=7562

http://lkml.org/lkml/2007/4/20/404
http://lkml.org/lkml/2007/3/25/113

Just reverse it for 2.6.21-final, having broken X server is somehow
better than unbootable system.

150f7e3cfe [POWERPC] cell: enable RTAS-based PTCAL for Cell XDR memory
Enable Periodic Recalibration (PTCAL) support for Cell XDR memory,
using the new ibm,cbe-start-ptcal and ibm,cbe-stop-ptcal RTAS calls.

Tested on QS20 and QS21 (by Thomas Huth). It seems that SLOF has
problems disabling, at least on QS20; this patch should only be
used once these problems have been addressed.
