b6e3590f81 [PATCH] x86: Allow percpu variables to be page-aligned
Let's allow page-alignment in general for per-cpu data (wanted by Xen, and
Ingo suggested KVM as well).

Because larger alignments can use more room, we increase the max per-cpu
memory to 64k rather than 32k: it's getting a little tight.

49c3df6aaa [PATCH] x86: Move swsusp __pa() dependent code to arch portion
o __pa() should be used only on kernel linearly mapped virtual addresses
  and not on kernel text and data addresses.

o Hibernation code needs to determine the physical address associated
  with kernel symbol to mark a section boundary which contains pages which
  don't have to be saved and restored during hibernate/resume operation.

o Move this piece of code in arch dependent section. So that architectures
  which don't have kernel text/data mapped into kernel linearly mapped
  region can come up with their own ways of determining physical addresses
  associated with a kernel text.

e4bb688d9f [POWERPC] bootwrapper: Fix array handling in dt_xlate_reg().
This fixes a few bugs in how dt_xlate_reg() handles address arrays:

1. copy_val() was copying into the wrong end of the array, resulting
in random stack garbage at the other end.
2. dt_xlate_reg() was getting the result from the wrong end of the array.
3. add_reg() and sub_reg() were treating the arrays as
little-endian rather than big-endian.
4. add_reg() only returned an error on a carry out of the entire
array, rather than out of the naddr portion.
5. The requested reg resource was checked to see if it exceeded
the size of the reg property, but not to see if it exceeded the
size of the buffer.

37f01d64d8 [POWERPC] Abolish PHYS_FMT macro from arch/powerpc
32-bit powerpc systems define a macro, PHYS_FMT, giving a printf
format string fragment for displaying physical addresses, since most
32-bit powerpc platforms use 32-bit physical addresses but a few use
64-bit physical addresses.

This macro is used in exactly one place, a rare error message, where
we can solve the problem more simply by just unconditionally casting
the address up to 64-bit quantity before formatting it.

This patch does so, meaning that as we bring MMU definitions from
asm-ppc over to asm-powerpc, cleaning them up in the process, we don't
need to implement this ugly macro (which additionally has a very bad
name for something global).

6210230725 [POWERPC] Cleanup and fix breakage in tlbflush.h
BenH's commit a741e67969 in powerpc.git,
although (AFAICT) only intended to affect ppc64, also has side-effects
which break 44x.  I think 40x, 8xx and Freescale Book E are also
affected, though I haven't tested them.

The problem lies in unconditionally removing flush_tlb_pending() from
the versions of flush_tlb_mm(), flush_tlb_range() and
flush_tlb_kernel_range() used on ppc64 - which are also used the
embedded platforms mentioned above.

The patch below cleans up the convoluted #ifdef logic in tlbflush.h,
in the process restoring the necessary flushes for the software TLB
platforms.  There are three sets of definitions for the flushing
hooks: the software TLB versions (revised to avoid using names which
appear to related to TLB batching), the 32-bit hash based versions
(external functions) amd the 64-bit hash based versions (which
implement batching).

It also moves the declaration of update_mmu_cache() to always be in
tlbflush.h (previously it was in tlbflush.h except for PPC64, where it
was in pgtable.h).

Booted on Ebony (440GP) and compiled for 64-bit and 32-bit
multiplatform.

f65573314e [POWERPC] Re-organize Kconfig code for 4xx in arch/powerpc
Now that we always take a device tree in arch/powerpc, there's no good
reason not to allow a single kernel to support multiple embedded 4xx
boards - the correct platform code can be selected based on the device
tree information.

Therefore, this patch re-arranges the 4xx Kconfig code to allow this.
In addition we:
	- use "select" instead of depends to configure the correct
	  config options for specific 4xx CPUs and workarounds, which
	  makes the information about specific boards and CPUs less
	  scattered.
	- Some old, unused (in arch/powerpc) config options are
	  removed: WANT_EARLY_SERIAL, IBM_OCP, etc.

This adds cuboot support for MPC83xx platforms.

A device tree used with this must have linux,stdout-path in /chosen and
linux,network-index in any network device nodes that need mac addresses
assigned.

9b1c59e256 [POWERPC] bootwrapper: Add ppcboot.h
This file describes the bd_t struct, which is used by old versions of
U-boot to pass information to the kernel.  Platform code that needs to
interoperate with such firmware can use this; it should not be used for
anything new.

0fdd717ed4 [POWERPC] bootwrapper: Add a cuboot platform and a cuImage target
The cuImage target will build a uImage with bootwrapper code and a device
tree.  The default device tree and platform file are determined by the
kernel configuration.

270429baa9 [POWERPC] bootwrapper: Add CONFIG_DEVICE_TREE
This provides a way to tell the bootwrapper makefile which device tree to
include by default.  The wrapper can still be invoked standalone to wrap
with a different device tree without reconfiguring the kernel, if that is
desired.

The user will only be asked to provide a device tree if the platform
selects CONFIG_WANT_DEVICE_TREE.
