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: Fix building of arch/powerpc/mm/mem.o when MEMORY_HOTPLUG=y and SPARSEMEM=n

2008-07-03T06:58:07+00:00

Currently the kernel fails to build with the above config options with:
  CC      arch/powerpc/mm/mem.o
arch/powerpc/mm/mem.c: In function 'arch_add_memory':
arch/powerpc/mm/mem.c:130: error: implicit declaration of function 'create_section_mapping'

This explicitly includes asm/sparsemem.h in arch/powerpc/mm/mem.c and
moves the guards in include/asm-powerpc/sparsemem.h to protect the
SPARSEMEM specific portions only.

[POWERPC] Add error return from htab_remove_mapping()

2008-04-01T09:43:08+00:00

If the platform doesn't support hpte_removebolted(), gracefully
return failure rather than success.

[POWERPC] Add code for removing HPTEs for parts of the linear mapping

2008-02-26T11:17:03+00:00

For memory remove, we need to clean up htab mappings for the
section of the memory we are removing.

This implements support for removing htab bolted mappings for pSeries
logical partitions.  Other sub-archs may need to implement similar
functionality for hotplug memory remove to work on them.

[POWERPC] PS3: Remove lpar address workaround

2008-01-25T11:52:53+00:00

Remove the PS3 workaround needed to support sparsemem SPU mappings.
The SPU mappings no longer use sparsemem, so this workaround is no
longer needed.

[POWERPC] ps3: add lpar addressing

2006-12-04T09:40:52+00:00

Adds some needed bits for a config option PS3_USE_LPAR_ADDR that disables
the PS3 lpar address translation mechanism.  This is a currently needed
workaround for limitations in the design of the generic cell spu support.

[PATCH] powerpc: sanitize header files for user space includes

2006-01-09T04:13:08+00:00

include/asm-ppc/ had #ifdef __KERNEL__ in all header files that
are not meant for use by user space, include/asm-powerpc does
not have this yet.

This patch gets us a lot closer there. There are a few cases
where I was not sure, so I left them out. I have verified
that no CONFIG_* symbols are used outside of __KERNEL__
any more and that there are no obvious compile errors when
including any of the headers in user space libraries.

[PATCH] powerpc: numa placement for dynamically added memory

2006-01-09T03:51:57+00:00

This places dynamically added memory within the appropriate
numa node.  A new routine hot_add_scn_to_nid() replicates most of
the memory scanning code in parse_numa_properties().

[PATCH] ppc64: Increase sparsemem defaults

2005-11-11T11:21:41+00:00

The definitions in sparsemem.h arent sufficient. We currently sell
machines with 2TB of RAM, and in order to give us room for a few years
growth lets set it to 16TB.

[PATCH] revised Memory Add Fixes for ppc64

2005-11-08T04:17:13+00:00

Add the create_section_mapping() routine to create hptes for memory
sections dynamically added after system boot.
