* [PARISC] Ensure Space ID hashing is turned offKyle McMartin2006-06-271-1/+9
| | | | | | | | | | | Check PDC_CACHE to see if spaceid hashing is turned on, and fail to boot if that is the case. However, some old machines do not implement the PDC_CACHE_RET_SPID firmware call, so continue to boot if the call fails because of PDC_BAD_OPTION (but fail in all other error returns).

* [PARISC] Match show_cache_info with realityKyle McMartin2006-06-271-8/+10
| | | | | | | | show_cache_info and struct pdc_cache_cf were out of sync with published documentation. Fix the reporting of cache associativity and update the pdc_cache_cf bitfields to match documentation. Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
* [PARISC] Misc. janitorial workHelge Deller2006-04-211-2/+2
| | | | | | | | Fix a spelling mistake, add a KERN_INFO flag, and fix some whitespace uglies. Signed-off-by: Helge Deller <deller@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
* [PARISC] Add parisc implementation of flush_kernel_dcache_page()James Bottomley2006-03-301-3/+3
| | | | | | | | We need to do a little renaming of our original syntax because of the difference in arguments. Signed-off-by: James Bottomley <jejb@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
* [PARISC] Make local cache flushes take a void *Matthew Wilcox2006-01-101-4/+4
| | | | | | | | | | | | | 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.

* [PARISC] Add __read_mostly section for pariscHelge Deller2006-01-101-6/+6
| | | | | | | | Flag a whole bunch of things as __read_mostly on parisc. Also flag a few branches as unlikely() and cleanup a bit of code. Signed-off-by: Helge Deller <deller@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
* [PATCH] mm: parisc pte atomicityHugh Dickins2005-10-291-15/+9
| | | | | | | | | | | | 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.

* [PARISC] Fix parisc_setup_cache_timing to choose a better flush thresholdStuart Brady2005-10-211-4/+6
| | | | | | | | | | | | | | | | update comment about CAFL_STRIDE Signed-off-by: Kyle McMartin <kyle@parisc-linux.org> Fixed a bug in parisc_setup_cache_timing() which caused it to calculate a poor value for parisc_cache_flush_threshold. Thanks to Joel Soete for spotting the bug. Thanks to James Bottomley for pointing out the clean way to fix this.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
