* [PARISC] Fix BLK_BOUNCE_HIGH on parisc by initializing max_low_pfnGrant Grundler2006-01-10
| | | | | | | | | max_low_pfn was not being set in arch/parisc/mm/init.c, causing severe problems whenever anything tried to use BLK_BOUNCE_HIGH. Set it to max_pfn like other similar architectures do. Signed-off-by: Grant Grundler <grundler@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
* [PARISC] Fix GSC graphics cards with 64MB regionsMatthew Wilcox2006-01-10
| | | | | | | | | Make knapps work with its 64MB gfx card. I probably just broke another machine in the process, but assuming 64MB when 64MB aligned is probably safer than assuming 32MB all the time.

* [PARISC] Fix and cleanup ioremap.c to work with 4level-fixup.hKyle McMartin2006-01-10
| | | | | | | | | Fixup ioremap a bit. It seems to work on 32-bit kernels, but fails miserably on the first ioremapped access on 64-bit kernels. Also, having STI enabled causes it to fail. Probably because we're passing an ioremapped region to a real-mode STI call... Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
* [PARISC] Make local cache flushes take a void *Matthew Wilcox2006-01-10
| | | | | | | | | | | | | Make flush_data_cache_local, flush_instruction_cache_local and flush_tlb_all_local take a void * so they don't have to be cast when using on_each_cpu(). This becomes a problem when on_each_cpu is a macro (as it is in current -mm). Also move the prototype of flush_tlb_all_local into tlbflush.h and remove its declaration from .c files.

* [PATCH] m68knommu: fix a5 reg corruption in signal handlersGreg Ungerer2006-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a patch adapted from a posting by Andrea Tarani which was pointed out to me by Bernardo Innocenti. Thanks to both of them for their help and patience. The original posting is here: http://mailman.uclinux.org/pipermail/uclinux-dev/2005-July/033543.html The problem first manifest itself as busybox ping terminating with an "Illegal instruction". I reduced this to a test case and found that variable size arrays allocated on the stack could lead to stacks not aligned on 32 bit boundaries. For the Coldfire this proved fatal. Having been pointed out this patch by Bernardo, I applied it and it fixed the first test case. I then went back to busybox's ping. This still failed with "Illegal instruction", but in a different way. Before it depended on the size allocated for the ping buffer, now it happened every time. I also found it depended on optimisation level (gcc-3.4.0) -Os was okay but not -O2. After a lot of looking, it turned out that register a5 was being corrupted by the signal handler (after applying the patch). I re-worked the patch a bit to save/restore a5 and now all seems well.
