[PARISC] Add prototypes for flush_user_dcache_range and flush_user_icache_range

2007-02-17T05:43:51Z

They're called from signal.c, so need to be prototyped Signed-off-by: Matthew Wilcox Signed-off-by: Kyle McMartin

[ARM] pass vma for flush_anon_page()

2007-01-08T19:49:54Z

Since get_user_pages() may be used with processes other than the current process and calls flush_anon_page(), flush_anon_page() has to cope in some way with non-current processes. It may not be appropriate, or even desirable to flush a region of virtual memory cache in the current process when that is different to the process that we want the flush to occur for. Therefore, pass the vma into flush_anon_page() so that the architecture can work out whether the 'vmaddr' is for the current process or not. Signed-off-by: Russell King

[PATCH] Optimize D-cache alias handling on fork

2006-12-13T17:27:08Z

Virtually index, physically tagged cache architectures can get away without cache flushing when forking. This patch adds a new cache flushing function flush_cache_dup_mm(struct mm_struct *) which for the moment I've implemented to do the same thing on all architectures except on MIPS where it's a no-op.

[PARISC] parisc specific kmap API implementation for pa8800

2006-10-04T12:46:21Z

This patch fixes the pa8800 at a gross level (there are still other subtle incoherency issues which can still cause crashes and HPMCs). What it does is try to force eject inequivalent aliases before they become visible to the L2 cache (which is where we get the incoherence problems). A new function (parisc_requires_coherency) is introduced in asm/processor.h to identify the pa8x00 processors (8800 and 8900) which have the issue.

[PARISC] Add parisc implementation of flush_kernel_dcache_page()

2006-03-30T17:48:44Z

We need to do a little renaming of our original syntax because of the difference in arguments. Signed-off-by: James Bottomley Signed-off-by: Kyle McMartin

[PATCH] mm: parisc pte atomicity

2005-10-30T04:40:42Z

There's a worrying function translation_exists in parisc cacheflush.h, unaffected by split ptlock since flush_dcache_page is using it on some other mm, without any relevant lock. Oh well, make it a slightly more robust by factoring the pfn check within it. And it looked liable to confuse a camouflaged swap or file entry with a good pte: fix that too.
