This brings in a lot of changes from arch/ppc64/kernel/pmac_*.c to
arch/powerpc/platforms/powermac/*.c and makes various minor tweaks
elsewhere. On the powermac we now initialize ppc_md by copying
the whole pmac_md structure into it, which required some changes in
the ordering of initializations of individual fields of it.

Moved init_boot_display from arch/ppc64/kernel/pmac_setup.c to
arch/ppc64/kernel/btext.c and declared it in asm-ppc64/btext.h.
Call it from init_early rather than pmac_init_early.

... for consistency with ppc32 and to make the powermac merge easier.
Also make it use just a single resource in the host bridge for multiple
consecutive elements of the ranges property.

Merge ppc32 and ppc64 versions of thread_info.h. They were pretty
similar already, the chief changes are:
- Instead of inline asm to implement current_thread_info(),
which needs to be different for ppc32 and ppc64, we use C with an
asm("r1") register variable. gcc turns it into the same asm as we
used to have for both platforms.
- We replace ppc32's 'local_flags' with the ppc64
'syscall_noerror' field. The noerror flag was in fact the only thing
in the local_flags field anyway, so the ppc64 approach is simpler, and
means we only need a load-immediate/store instead of load/mask/store
when clearing the flag.
- In readiness for 64k pages, when THREAD_SIZE will be less
than a page, ppc64 used kmalloc() rather than get_free_pages() to
allocate the kernel stack. With this patch we do the same for ppc32,
since there's no strong reason not to.
- For ppc64, we no longer export THREAD_SHIFT and THREAD_SIZE
via asm-offsets, thread_info.h can now be safely included in asm, as
on ppc32.
Built and booted on G4 Powerbook (ARCH=ppc and ARCH=powerpc) and
Power5 (ARCH=ppc64 and ARCH=powerpc).

This declares powersave_nap in system.h and makes it an int everywhere,
fixes typos for the maple platform, fixes a couple of places where
I missed removing the last two arguments from a message_pass function,
and makes ppc64 consistent with ppc32 in the type of the
pci_bridge.cfg_data field.

Except for smu.h, which moved from asm-ppc64 to asm-powerpc, all
of these moved from asm-ppc to asm-powerpc. In each case the
asm-ppc64 version (if there was one) was just a single line
including the asm-ppc version.

Having it here rather than in arch/ppc64/kernel/smp.c means that
we can use it on 32-bit SMP systems easily with ARCH=powerpc.

This patch merges types.h into include/asm-powerpc. The only real change is
the removal of the include of linux/config.h from the 32-bit version - it
doesn't appear to be necessary.
This patch has been built on several different 32 and 64-bit platforms,
and booted on mpc8540_ads.

This patches the ppc32 and ppc64 versions of the headers and .c files
with helper functions for manipulating the performance counting
hardware. As a side effect, it removes use of the term "perfmon" from
ppc32, thus avoiding confusion with the unrelated performance counter
interface from HP Labs also called "perfmon".
Built, but not booted, for g5, pSeries, iSeries, and 32-bit Powermac
with both ARCH=powerpc and ARCH=ppc{,64} as appropriate.

We now use the merged time.c for both 32-bit and 64-bit compilation
with ARCH=powerpc, and for ARCH=ppc64, but not for ARCH=ppc32.
This removes setup_default_decr (folds its function into time_init)
and moves wakeup_decrementer into time.c. This also makes an
asm-powerpc/rtc.h.

A few things change for consistency between ppc32 and ppc64:
idle functions return void; *_get_boot_time functions return
unsigned long (i.e. time_t) rather than filling in a struct rtc_time
(since that's useful to the callers and easier for pmac to
generate); *_get_rtc_time and *_set_rtc_time functions take
a struct rtc_time; irq_canonicalize is gone; nvram_sync returns
void.

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).

This removes three headers from include/asm-ppc64 that are now in
include/asm-powerpc and are sufficiently similar that they can be
used with ARCH=ppc64.
