2015-02-06mm/debug_pagealloc: fix build failure on ppc and some other archsJoonsoo Kim1-7/+0
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.

2010-10-27MN10300: Allow some cacheflushes to be avoided if cache snooping is availableDavid Howells1-6/+10
The AM34 core is able to do cache snooping, and so can skip some of the cache flushing. Signed-off-by: David Howells <dhowells@redhat.com>
2010-10-27MN10300: SMP: Differentiate local cache flushingAkira Takeuchi1-0/+50
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.

2010-10-27MN10300: Cacheflush functions should take unsigned long addressesAkira Takeuchi1-9/+9
The functions that perform cache flushing should take addresses of unsigned long type, not unsigned int. Signed-off-by: Akira Takeuchi <takeuchi.akr@jp.panasonic.com> Signed-off-by: Kiyoshi Owada <owada.kiyoshi@jp.panasonic.com> Signed-off-by: David Howells <dhowells@redhat.com>
2010-10-27MN10300: Reorder asm/cacheflush.h to put primitives firstDavid Howells1-44/+44
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. Signed-off-by: David Howells <dhowells@redhat.com>
2010-10-27MN10300: Provide a MN10300_CACHE_ENABLED config optionDavid Howells1-3/+3
Provide a MN10300_CACHE_ENABLED config option as inverted logic of MN10300_CACHE_DISABLED to make things simpler. Signed-off-by: David Howells <dhowells@redhat.com>
2009-11-26block: add helpers to run flush_dcache_page() against a bio and a request's ↵Ilya Loginov1-0/+1
pages 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.
