The only real user of this file outside platforms/iseries was
drivers/net/iseries_veth.c but all it wanted was ISERIES_HV_ADDR()
so we move that to abs_addr.h (and lowercase it).

Newer gcc's are generating this relocation, so the module loader needs to
handle it.

pSeries_irq_bus_setup is marked __devinit but references s7a_workaround
which is marked __initdata.
Depending on who got the memory for s7a_workaround (and if the value was
now positive), it was possible for PCI hotplugged devices to have 3
subtracted from their interrupt number. This would happen randomly and
caused me much confusion :)

This used to be inline in include/asm-ppc64/unistd.h, but isn't
inline in the merged include/asm-powerpc/unistd.h, so we need a
definition here.

This is a bunch of mostly small fixes that are needed to get
ARCH=powerpc to compile for 64-bit. This adds setup_64.c from
arch/ppc64/kernel/setup.c and locks.c from arch/ppc64/lib/locks.c.

Since lparmap.s gets included in arch/powerpc/kernel/head_64.S,
this avoids depending on a file in another directory.

This moves the remaining files in arch/ppc64/mm to arch/powerpc/mm,
and arranges that we use them when compiling with ARCH=ppc64.

The only real change here is that lmb_enforce_memory_limit now takes
the memory_limit as a parameter instead of as a global variable.

This changes symbols like HID0, SPRG3, SRR0, SRR1 etc. that refer to
special purpose registers to SPRN_HID0, SPRN_SPRG3, etc. Using the
SPRN_ symbols clutters the namespace less, and the forthcoming merge
of asm/processor.h and asm/reg.h is going to remove the non-SPRN_
versions.

- added typedef unsigned int __nocast gfp_t;
- replaced __nocast uses for gfp flags with gfp_t - it gives exactly
the same warnings as far as sparse is concerned, doesn't change
generated code (from gcc point of view we replaced unsigned int with
typedef) and documents what's going on far better.

Use idle_power4.S from ppc64 as we are not going to support
32 bit power4 in the merged tree.
Merge ppc64 traps.c into powerpc traps.c:
use ppc64 versions of exception routine names
(as they don't have StudlyCaps)
make all the versions if die() have the same
prototype

BUILD_BUG_ON(1) is asking for trouble (and getting it) when used in that
manner - dead code elimination happens after we parse it and invalid
type is invalid type, dead code or not.
It might be version-dependent, but at least 4.0.1 refuses to accept
that.

My previous patch fixing invalidation of huge PTEs wasn't good enough, we
still had an issue if a PTE invalidation batch contained both small and
large pages. This patch fixes this by making sure the batch is flushed if
the page size fed to it changes.

Mikey and I were testing kexec and hit a lockup. It turns out gcc 4.0
optimises the kexec_prepare_cpus loop so we avoid reloading paca.hw_cpu_id.

Merged cputable.h between ppc32 and ppc64. In doing this removed support
for the BEGIN_FTR_SECTION/END_FTR_SECTION macros in C code since they
dont compile correctly. C code should use cpu_has_feature(). This is
based on Arnd Bergmann's initial patch.

iSeries_setup.c becomes setup.c

Also moved iSeries_[gs]et_rtc_time and iSeries_get_boot_time into
mf.c since they are just small wrappers around mf_ functions.
