Jon Mason 2ef9481e66 [PATCH] powerpc: trivial: modify comments to refer to new location of files
This patch removes all self references and fixes references to files
in the now defunct arch/ppc64 tree.  I think this accomplises
everything wanted, though there might be a few references I missed.

Becky Bruce a7cb03375d [PATCH] powerpc/ppc: Add missing isyncs in head_fsl_booke.S
The e500 core reference manual indicates that isync is required
after mtmsr(DE bit) and mtspr DBCR0.  Add isyncs to make the code
conform to the spec.

Kumar Gala 3d904eef54 [PATCH] ppc32: replace use of _GLOBAL with .globl for ppc32
The _GLOBAL() macro is for text symbols only. Changed to using
.globl for .data symbols.  This is also needed in ppc32 land
to allow FSL Book-E, 40x, and 44x to work.

Stephen Rothwell dc1c1ca3dc powerpc: merge idle_power4.S and trapc.s
Use idle_power4.S from ppc64 as we are not going to support
32 bit power4 in the merged tree.

Merge ppc64 traps.c into powerpc traps.c:
	use ppc64 versions of exception routine names
		(as they don't have StudlyCaps)
	make all the versions if die() have the same
		prototype

Kumar Gala 5f7c690728 [PATCH] powerpc: Merged ppc_asm.h
Merged ppc_asm.h between ppc32 & ppc64.  The majority of the file is
common between the two architectures excluding how a single GPR is
saved/restored and which GPRs are non-volatile.

Additionally, moved the ASM_CONST macro used on ppc64 into ppc_asm.h.

Kumar Gala a2f40ccd29 [PATCH] ppc32: Added support for the Book-E style Watchdog Timer
PowerPC 40x and Book-E processors support a watchdog timer at the processor
core level.  The timer has implementation dependent timeout frequencies
that can be configured by software.

One the first Watchdog timeout we get a critical exception.  It is left to
board specific code to determine what should happen at this point.  If
nothing is done and another timeout period expires the processor may
attempt to reset the machine.

Command line parameters:
  wdt=0 : disable watchdog (default)
  wdt=1 : enable watchdog

  wdt_period=N : N sets the value of the Watchdog Timer Period.

  The Watchdog Timer Period meaning is implementation specific. Check
  User Manual for the processor for more details.

This patch is based off of work done by Takeharu Kato.

Kumar Gala 33d9e9b56d [PATCH] ppc32: Add support for Freescale e200 (Book-E) core
The e200 core is a Book-E core (similar to e500) that has a unified L1 cache
and is not cache coherent on the bus.  The e200 core also adds a separate
exception level for debug exceptions.  Part of this patch helps to cleanup a
few cases that are true for all Freescale Book-E parts, not just e500.

Kumar Gala 252fcaed48 [PATCH] ppc32: Fix some minor issues related to FSL Book-E KGDB support
Some debug registers needed to be initialized early on to allow proper
support for KGDB.  Additionally, we need to setup the
ppc.md_early_serial_map function pointer on boards that have serial support
for KGDB.

Paul Mackerras 443a848cd3 [PATCH] ppc32: refactor FPU exception handling
Moved common FPU exception handling code out of head.S so it can be used by
several of the sub-architectures that might of a full PowerPC FPU.

Also, uses new CONFIG_PPC_FPU define to fix alignment exception handling
for floating point load/store instructions to only occur if we have a
hardware FPU.

Kumar Gala f50b153b19 [PATCH] ppc32: Support 36-bit physical addressing on e500
To add support for 36-bit physical addressing on e500 the following changes
have been made.  The changes are generalized to support any physical address
size larger than 32-bits:

* Allow FSL Book-E parts to use a 64-bit PTE, it is 44-bits of pfn, 20-bits
  of flags.

* Introduced new CPU feature (CPU_FTR_BIG_PHYS) to allow runtime handling of
  updating hardware register (SPRN_MAS7) which holds the upper 32-bits of
  physical address that will be written into the TLB.  This is useful since
  not all e500 cores support 36-bit physical addressing.

* Currently have a pass through implementation of fixup_bigphys_addr

* Moved _PAGE_DIRTY in the 64-bit PTE case to free room for three additional
  storage attributes that may exist in future FSL Book-E cores and updated
  fault handler to copy these bits into the hardware TLBs.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
