4d9e55103a [POWERPC] Adjust TASK_SIZE on ppc32 systems to 3GB that are capable
All ppc32 systems except PReP and 8xx are capable of handling 3G of user
address space.  Old legacy had set this to 2GB and no one has bothered to
fix it.

8xx could be bumped up to 3GB if its SW TLB miss handlers were fixed up
to properly determine kernel/user addresses.

5dd57a1308 [POWERPC] 8xx: Move softemu8xx.c from arch/ppc
Previously, Soft_emulate_8xx was called with no implementation, resulting in
build failures whenever building 8xx without math emulation.  The
implementation is copied from arch/ppc to resolve this issue.

However, this sort of minimal emulation is not a very good idea other than
for compatibility with existing userspaces, as it's less efficient than
soft-float and can mislead users into believing they have soft-float.  Thus,
it is made a configurable option, off by default.

e00c5498a2 [POWERPC] mpc82xx: Update mpc8272ads, and factor out PCI and reset.
1. PCI and reset are factored out into pq2.c.  I renamed them from m82xx
to pq2 because they won't work on the Integrated Host Processor line of
82xx chips (i.e. 8240, 8245, and such).

2. The PCI PIC, which is nominally board-specific, is used on multiple
boards, and thus is used into pq2ads-pci-pic.c.

3. The new CPM binding is used.

4. General cleanup.

d831d0b83f [POWERPC] Implement clockevents driver for powerpc
This registers a clock event structure for the decrementer and turns
on CONFIG_GENERIC_CLOCKEVENTS, which means that we now don't need
most of timer_interrupt(), since the work is done in generic code.
For secondary CPUs, their decrementer clockevent is registered when
the CPU comes up (the generic code automatically removes the
clockevent when the CPU goes down).

517e22638c [POWERPC] Don't use SLAB/SLUB for PTE pages
The SLUB allocator relies on struct page fields first_page and slab,
overwritten by ptl when SPLIT_PTLOCK: so the SLUB allocator cannot then
be used for the lowest level of pagetable pages.  This was obstructing
SLUB on PowerPC, which uses kmem_caches for its pagetables.  So convert
its pte level to use normal gfp pages (whereas pmd, pud and 64k-page pgd
want partpages, so continue to use kmem_caches for pmd, pud and pgd).

d0f13e3c20 [POWERPC] Introduce address space "slices"
The basic issue is to be able to do what hugetlbfs does but with
different page sizes for some other special filesystems; more
specifically, my need is:

 - Huge pages

 - SPE local store mappings using 64K pages on a 4K base page size
kernel on Cell

 - Some special 4K segments in 64K-page kernels for mapping a dodgy
type of powerpc-specific infiniband hardware that requires 4K MMU
mappings for various reasons I won't explain here.

The main issues are:

 - To maintain/keep track of the page size per "segment" (as we can
only have one page size per segment on powerpc, which are 256MB
divisions of the address space).

 - To make sure special mappings stay within their allotted
"segments" (including MAP_FIXED crap)

 - To make sure everybody else doesn't mmap/brk/grow_stack into a
"segment" that is used for a special mapping

Some of the necessary mechanisms to handle that were present in the
hugetlbfs code, but mostly in ways not suitable for anything else.

The patch relies on some changes to the generic get_unmapped_area()
that just got merged.  It still hijacks hugetlb callbacks here or
there as the generic code hasn't been entirely cleaned up yet but
that shouldn't be a problem.

So what is a slice ?  Well, I re-used the mechanism used formerly by our
hugetlbfs implementation which divides the address space in
"meta-segments" which I called "slices".  The division is done using
256MB slices below 4G, and 1T slices above.  Thus the address space is
divided currently into 16 "low" slices and 16 "high" slices.  (Special
case: high slice 0 is the area between 4G and 1T).

Doing so simplifies significantly the tracking of segments and avoids
having to keep track of all the 256MB segments in the address space.

While I used the "concepts" of hugetlbfs, I mostly re-implemented
everything in a more generic way and "ported" hugetlbfs to it.

Slices can have an associated page size, which is encoded in the mmu
context and used by the SLB miss handler to set the segment sizes.  The
hash code currently doesn't care, it has a specific check for hugepages,
though I might add a mechanism to provide per-slice hash mapping
functions in the future.

The slice code provide a pair of "generic" get_unmapped_area() (bottomup
and topdown) functions that should work with any slice size.  There is
some trickiness here so I would appreciate people to have a look at the
implementation of these and let me know if I got something wrong.

3e4e97f42e [POWERPC] 86xx/85xx: Move 8641 PCI-Express to arch/powerpc/sysdev/fsl_pcie.c.
This move sets the stage for the use of generic PCI Express
code in 85xx and 86xx parts from FSL.  Subsequent patches
for 8548 and 8544 will be able to use this shared code.

17e638bc28 [POWERPC] Generic time suspend/resume code
This removes the time suspend/restore code that was done through
a PMU notifier in arch/platforms/powermac/time.c.

Instead, introduce arch/powerpc/sysdev/timer.c which creates a sys
device and handles time of day suspend/resume through that.

This should probably be replaced by using the generic RTC framework
but for now it gets rid of the arcane powermac specific hack.
