This corrects the documented interface for mpc52xx device trees.
Sound devices should be using 'sound' for the device_type field, not
the type of sound interface.

Using device_initcall makes it happen for every platform that
compiles this file in. This is really bad, for obvious reasons.
Instead, we use the .init field of the machine description. If
the platform needs the hook to do something specific it can provides
its own function and call mpc52xx_declare_of_platform_devices from
there. If not, the mpc52xx_declare_of_platform_devices function can
directly be used as the init hook.

When we switched over to the generic BUG mechanism we forgot to change
the assembly code which open-codes a WARN_ON() in enter_rtas(), so the
bug table got corrupted.
This patch provides an EMIT_BUG_ENTRY macro for use in assembly code,
and uses it in entry_64.S. Tested with CONFIG_DEBUG_BUGVERBOSE on ppc64
but not without -- I tried to turn it off but it wouldn't go away; I
suspect Aunt Tillie probably needed it.
This version gets __FILE__ and __LINE__ right in the assembly version --
rather than saying include/asm-powerpc/bug.h line 21 every time which is
a little suboptimal.

The powerpc specific version of hugetlb_get_unmapped_area() makes some
unwarranted assumptions about what checks have been made to its
parameters by its callers. This will lead to a BUG_ON() if a 32-bit
process attempts to make a hugepage mapping which extends above
TASK_SIZE (4GB).
I'm not sure if these assumptions came about because they were valid
with earlier versions of the get_unmapped_area() path, or if it was
always broken. Nonetheless this patch fixes the logic, and removes
the crash.

For 32-bit processes, the getcontext side of the swapcontext system
call (i.e. the saving of the context when the first argument is
non-NULL) has to set the ctx->uc_mcontext.uc_regs pointer to the place
where it saves the registers. Which it does, but it doesn't ensure
that the pointer is 16-byte aligned. 16-byte alignment is needed
because the Altivec/VMX registers are saved in there, and they need to
be on a 16-byte boundary.
This fixes it by ensuring the appropriate alignment of the pointer.
This issue was pointed out by Jakub Jelinek.

The patch adding support for zImage.ps3 didn't add a zImage.initrd.ps3
target causing builds of zImage.initrd to fail when ps3 is included in
the .config. The current method of generating ps3 images doesn't support
initrd's yet, so we create a dummy target that only displays a warning
message instead.

On some oldworld PowerMacs, OF doesn't assign interrupts properly
beyond P2P bridges. Fortunately, the fix is easy as all those machines
just wire all IRQ lines together to one IRQ which is assigned to the
bridge itself. We already have a special function for parsing Apple
OldWorld interrupts which are special, so let's add to it the ability
to walk up the PCI tree to find interrupts.
This fixes irqs on the lower slots of s900 clones among others.

The difference between 'nid' and 'node' fields in an
spu structure was used incorrectly. The common 'node'
number now reflects the NUMA node, and it is used
in other places in the code as well.
The 'nid' value is meaningful only in one place, namely
the computation of the interrupt numbers based on the
physical location of an spu. Consequently, we look it
up directly in the place where it is used now.

This makes powerpc use the generic BUG machinery. The biggest reports the
function name, since it is redundant with kallsyms, and not needed in general.
There is an overall reduction of code, since module_32/64 duplicated several
functions.
Unfortunately there's no way to tell gcc that BUG won't return, so the BUG
macro includes a goto loop. This will generate a real jmp instruction, which
is never used.
