mm/debug_pagealloc: fix build failure on ppc and some other archs

2015-02-05T21:35:30+00:00

Kim Phillips reported following build failure.

  LD      init/built-in.o
  mm/built-in.o: In function `free_pages_prepare':
  mm/page_alloc.c:770: undefined reference to `.kernel_map_pages'
  mm/built-in.o: In function `prep_new_page':
  mm/page_alloc.c:933: undefined reference to `.kernel_map_pages'
  mm/built-in.o: In function `map_pages':
  mm/compaction.c:61: undefined reference to `.kernel_map_pages'
  make: *** [vmlinux] Error 1

Reason for this problem is that commit 031bc5743f15
("mm/debug-pagealloc: make debug-pagealloc boottime configurable")
forgot to remove the old declaration of kernel_map_pages() for some
architectures.  This patch removes them to fix build failure.

MN10300: Allow some cacheflushes to be avoided if cache snooping is available

2010-10-27T16:28:46+00:00

The AM34 core is able to do cache snooping, and so can skip some of the cache
flushing.

MN10300: SMP: Differentiate local cache flushing

2010-10-27T16:28:45+00:00

Differentiate local cache flushing from global cache flushing so that they can
be done differently on SMP systems.

Rename the cache functions from:

	mn10300_[id]cache_*()

to:

	mn10300_[id]_localcache_*()

and on a UP system, assign the global labels to the local labels.

MN10300: Cacheflush functions should take unsigned long addresses

2010-10-27T16:28:44+00:00

The functions that perform cache flushing should take addresses of unsigned
long type, not unsigned int.

MN10300: Reorder asm/cacheflush.h to put primitives first

2010-10-27T16:28:43+00:00

Reorder asm/cacheflush.h to put arch primitives first, before the main
functions so that the main functions can be inline asm rather than #defines
when non-trivial.

MN10300: Provide a MN10300_CACHE_ENABLED config option

2010-10-27T16:28:42+00:00

Provide a MN10300_CACHE_ENABLED config option as inverted logic of
MN10300_CACHE_DISABLED to make things simpler.

block: add helpers to run flush_dcache_page() against a bio and a request's pages

2009-11-26T08:16:19+00:00

Mtdblock driver doesn't call flush_dcache_page for pages in request.  So,
this causes problems on architectures where the icache doesn't fill from
the dcache or with dcache aliases.  The patch fixes this.

The ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE symbol was introduced to avoid
pointless empty cache-thrashing loops on architectures for which
flush_dcache_page() is a no-op.  Every architecture was provided with this
flush pages on architectires where ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE is
equal 1 or do nothing otherwise.

See "fix mtd_blkdevs problem with caches on some architectures" discussion
on LKML for more information.
