Bryan Rosenburg pointed out that the definition of PT_FPSCR in
include/asm-ppc64/ptrace.h is wrong.  The patch below fixes it.

I have made a mistake in the kernel header i2o-dev.h.  All structures there
begin with the "iop" first, but in my structure the order is reversed.

Somehow we've been placing the rtas error_log file at /proc/ppc64/error_log,
which breaks at least one application I know of.  It is supposed to be at
/proc/ppc64/rtas/error_log (this is the 2.4 behavior).

This patch updates several of the ppc32 defconfigs.

From: Paul Mackerras <paulus@samba.org>

On machines with Altivec (i.e.  G4 and G5 processors), the altivec
floating-point instructions can operate in two modes: one where
denormalized inputs or outputs are truncated to zero, and one where they
aren't.  In the latter mode the processor can take an exception when it
encounters denormalized floating-point inputs or outputs rather than
dealing with them in hardware.

This patch adds code to deal properly with the exception, by emulating the
instruction that caused the exception.  Previously the kernel just switched
the altivec unit into the truncate-to-zero mode, which works but is a bit
gross.  Fortunately there are only a limited set of altivec instructions
which can generate the assist exception, so we don't have to emulate the
whole altivec instruction set.

This patch also makes sure that we always have a handler for the altivec
unavailable exception.  Without this, if you run a kernel that is not
configured for altivec support on a machine with altivec, it works fine
until a user process tries to execute an altivec instruction.  At that
point the kernel thinks it has taken an unknown exception and panics.  With
this patch it sends a SIGILL to the process instead.

From: Paul Mackerras <paulus@samba.org>

This patch does nothing but fix up whitespace in three files in arch/ppc.
It deletes trailing blanks and tabs in several places and joins two lines
that didn't need to be split.

This patch adds preliminary support for the IBM PowerPC 750GX.  In summary
this part is a PPC750FX ramped to 1 GHz with a 1MB 4-way L2 and more
advanced I/O pipelining.  It is beginning to appear in embedded systems and
was rumored to be under evaluation inside Apple.  Tested on PVR 70020101;
please merge.

arch/ppc64/lib/locks.c was recently added by Paulus' lock rewrite. It's
always compiled, which breaks non-SMP builds. Below patch makes it depend
on CONFIG_SMP.

This re-jigs atomic.h by providing atomic_add_return and
atomic_sub_return as other architectures do.  This allows us to
implement the atomic ops that test the new value without having
to write the underlying atomic operation in various forms.

Patch from: Ian Campbell

This changes the atomic_t in struct page named count into a private
member _count which breaks arch/arm/mm/init.c at line 80 which reads
page->count directly in show_mem().
                                                                                
The comments in the above changeset suggest that page_count(page) is
precisely equal to the old page->count semantics, even though the
semantics of _count are different, so I think the following is correct
