powerpc: Move include files to arch/powerpc/include/asm

2008-08-04T02:02:00+00:00

from include/asm-powerpc.  This is the result of a

mkdir arch/powerpc/include/asm
git mv include/asm-powerpc/* arch/powerpc/include/asm

Followed by a few documentation/comment fixups and a couple of places
where  was being used explicitly.  Of the latter only
one was outside the arch code and it is a driver only built for powerpc.

[POWERPC] Split out asm-ppc/mmu.h portions for PowerPC 8xx

2007-07-03T08:00:28+00:00

arch/powerpc still relies on asm-ppc/mmu.h for some 32-bit MMU types.
This patch is another step towards fixing this.  It takes the portions
of asm-ppc/mmu.h related to 8xx embedded CPUs which are still relevant
in arch/powerpc and puts them in a new asm-powerpc/mmu-8xx.h,
included when appropriate from asm-powerpc/mmu.h.

[POWERPC] Split out asm-ppc/mmu.h portions for the "classic" hash-based MMU

2007-06-14T12:30:15+00:00

[POWERPC] Revise PPC44x MMU code for arch/powerpc

2007-05-02T10:04:29+00:00

This patch takes the definitions for the PPC44x MMU (a software loaded
TLB) from asm-ppc/mmu.h, cleans them up of things no longer necessary
in arch/powerpc and puts them in a new asm-powerpc/mmu_44x.h file.  It
also substantially simplifies arch/powerpc/mm/44x_mmu.c and makes a
couple of small fixes necessary for the 44x MMU code to build and work
properly in arch/powerpc.

[POWERPC] Prepare for splitting up mmu.h by MMU type

2007-04-27T11:14:26+00:00

Currently asm-powerpc/mmu.h has definitions for the 64-bit hash based
MMU.  If CONFIG_PPC64 is not set, it instead includes asm-ppc/mmu.h
which contains a particularly horrible mess of #ifdefs giving the
definitions for all the various 32-bit MMUs.

It would be nice to have the low level definitions for each MMU type
neatly in their own separate files.  It would also be good to wean
arch/powerpc off dependence on the old asm-ppc/mmu.h.

This patch makes a start on such a cleanup by moving the definitions
for the 64-bit hash MMU to their own file, asm-powerpc/mmu_hash64.h.
Definitions for the other MMUs still all come from asm-ppc/mmu.h,
however each MMU type can now be one-by-one moved over to their own
file, in the process cleaning them up stripping them of cruft no
longer necessary in arch/powerpc.

[POWERPC] spufs: make spu page faults not block scheduling

2007-04-23T19:18:55+00:00

Until now, we have always entered the spu page fault handler
with a mutex for the spu context held. This has multiple
bad side-effects:
- it becomes impossible to suspend the context during
  page faults
- if an spu program attempts to access its own mmio
  areas through DMA, we get an immediate livelock when
  the nopage function tries to acquire the same mutex

This patch makes the page fault logic operate on a
struct spu_context instead of a struct spu, and moves it
from spu_base.c to a new file fault.c inside of spufs.

We now also need to copy the dar and dsisr contents
of the last fault into the saved context to have it
accessible in case we schedule out the context before
activating the page fault handler.
