Subject: [PATCH 02/16] [PATCH] Restore lparmap.s include for iSeries

A mistake rebasing the series of ppc64 head.S cleanup patches meant
the #include of lparmap.s, needed for iSeries was lost.  This patch
puts it back again.

Subject: [PATCH 03/16] [PATCH] fix iSeries build for gcc-3.4

gcc 3.4 (at least the build we are using) puts the gcc generated .ident
string into a .note section at the end of the files it compiles (gcc
3.3.3-hammer and gcc 4.0.2 Debian puts it in the .text section).  This
means that the lparmap.s file we produce in the iSeries build may end with
a .note section.  When we include it into head.S, the assembler can no
longer resolve some of the conditional branches since the target label
ends up too far away.  This patch just forces us back to the .text section
after including lparmap.s.

The breakage was caused by my patch "iSeries build with newer assemblers
and compilers" (sha1-id: 2ad56496627630ebc99f06af5f81ca23e17e014e).

Subject: [PATCH 06/16] [PATCH] Create vio_bus_ops

Create vio_bus_ops so that we just pass a structure to vio_bus_init
instead of three separate function pointers.

Rearrange vio.h to avoid forward references. vio.h only needs
struct device_node from prom.h so remove the include and just
declare it.

Subject: [PATCH 08/16] [PATCH] Create include/asm-powerpc

The ppc and ppc64 trees are hopefully going to merge over time, so this
patch begins the process by creating a place for the merging of the
header files.

Create include/asm-powerpc (and move linkage.h into it from
asm-{ppc,ppc64} since we don't like empty directories).  Modify the
ppc and ppc64 Makefiles to cope.

Subject: [PATCH 11/16] [PATCH] PPC64: Don't try to claim memory from OF at 1GB
 mark

Some RS64-based machines (p620, F80, others) have problems with firmware
returning 0xdeadbeef instead of failure to allocations that end at the
1GB mark.

We have two options:
1. Detect the undocumented 0xdeadbeef return value and interpret it as
a failure.
2. Avoid allocating that high.

(2) is really the cleaner solution here. 768MB is plenty of room so use
that as the max alloc_top instead of 1GB.

Subject: [PATCH 16/16] [PATCH] Remove nested feature sections

The {BEGIN,END}_FTR_SECTION asm macros used in ppc64 to nop out
sections of code at runtime cannot be nested.  However, we do nest
them in hash_low.S.  We get away with it there, because there is
nothing between the BEGIN markers for each section.  However, that's
confusing to someone reading the code.

This patch removes the nested ifset and ifclr feature sections,
replacing them with a single feature section in the full mask/value
form.
