This section of code calls .audit_syscal_exit, but is inside CONFIG_AUDIT,
so it will fail to build if CONFIG_AUDITSYSCALL is not defined.
After discussion with David Woodhouse, change the ifdef to
CONFIG_AUDITSYSCALL

This simplifies the macros which are different between 32-bit and
64-bit. It also fixes a couple of printks on the bug->line element,
which is now a long.

A couple of instances of "i" that needed to be changed to "cpu_id"
got missed in the merge, because they were in CONFIG_TAU code.

Here's a revised version. This re-introduces the set_bits() function
from ppc64, which I removed because I thought it was unused (it exists
on no other arch). In fact it is used in the powermac interrupt code
(but not on pSeries).
- We use LARXL/STCXL macros to generate the right (32 or 64 bit)
instructions, similar to LDL/STL from ppc_asm.h, used in fpu.S
- ppc32 previously used a full "sync" barrier at the end of
test_and_*_bit(), whereas ppc64 used an "isync". The merged version
uses "isync", since I believe that's sufficient.
- The ppc64 versions of then minix_*() bitmap functions have changed
semantics. Previously on ppc64, these functions were big-endian
(that is bit 0 was the LSB in the first 64-bit, big-endian word).
On ppc32 (and x86, for that matter, they were little-endian. As far
as I can tell, the big-endian usage was simply wrong - I guess
no-one ever tried to use minixfs on ppc64.
- On ppc32 find_next_bit() and find_next_zero_bit() are no longer
inline (they were already out-of-line on ppc64).
- For ppc64, sched_find_first_bit() has moved from mmu_context.h to
the merged bitops. What it was doing in mmu_context.h in the first
place, I have no idea.
- The fls() function is now implemented using the cntlzw instruction
on ppc64, instead of generic_fls(), as it already was on ppc32.
- For ARCH=ppc, this patch requires adding arch/powerpc/lib to the
arch/ppc/Makefile. This in turn requires some changes to
arch/powerpc/lib/Makefile which didn't correctly handle ARCH=ppc.
Built and running on G5.

Cell uses the same code as pSeries for flashing the firmware
through rtas, so the implementation should not be part of
platforms/pseries.
Put it into arch/powerpc/kernel instead.

By parsing the command line earlier, we can add the mem= value to the
flattened device tree and let the generic code sort out the memory limit
for us.

We had a static memory_limit in prom.c, and then another one defined
in setup_64.c and used in numa.c, which resulted in the kernel crashing
when mem=xxx was given on the command line. This puts the declaration
in system.h and the definition in mem.c. This also moves the
definition of tce_alloc_start/end out of setup_64.c.

This fixes a bug where settimeofday would set the wrong parameters
in do_gtod, resulting in gettimeofday returning a value about 4
hours after the correct time. The bug was that we divided a
negative 64-bit value with do_div, which treated it as unsigned
and gave us a result that was approximately 1.8e10 too large
(since the divisor was 1e9).

Somehow we ended up with an #ifdef CONFIG_PPC64 around the export
of cur_cpu_spec, but raid6 as a module needs it on ppc32 as well
as ppc64.

The merged version follows the ppc64 version pretty closely mostly,
and in fact ARCH=ppc64 now uses the arch/powerpc/xmon version.
The main difference for ppc64 is that the 'p' command to call
show_state (which was always pretty dodgy) has been replaced by
the ppc32 'p' command, which calls a given procedure (so in fact
the old 'p' command behaviour can be achieved with 'p $show_state').

Since I sent the patch to purge bootinfo.h from ARCH=powerpc and
ARCH=ppc64, setup-common.c has come into existence, and another
#include of bootinfo.h slipped in. This patch removes it. It also
removes include/asm-ppc64/bootinfo.h, which somehow survived the
previous patch which was supposed to remove it.
