2006-03-20[SPARC64]: Kill pgtable quicklists and use SLAB.David S. Miller
Taking a nod from the powerpc port. With the per-cpu caching of both the page allocator and SLAB, the pgtable quicklist scheme becomes relatively silly and primitive. Signed-off-by: David S. Miller <davem@davemloft.net>
2006-03-20[SPARC64]: No need to D-cache color page tables any longer.David S. Miller
Unlike the virtual page tables, the new TSB scheme does not require this ugly hack. Signed-off-by: David S. Miller <davem@davemloft.net>
2006-03-20[SPARC64]: Move away from virtual page tables, part 1.David S. Miller
We now use the TSB hardware assist features of the UltraSPARC MMUs. SMP is currently knowingly broken, we need to find another place to store the per-cpu base pointers. We hid them away in the TSB base register, and that obviously will not work any more :-) Another known broken case is non-8KB base page size. Also noticed that flush_tlb_all() is not referenced anywhere, only the internal __flush_tlb_all() (local cpu only) is used by the sparc64 port, so we can get rid of flush_tlb_all(). The kernel gets it's own 8KB TSB (swapper_tsb) and each address space gets it's own private 8K TSB. Later we can add code to dynamically increase the size of per-process TSB as the RSS grows. An 8KB TSB is good enough for up to about a 4MB RSS, after which the TSB starts to incur many capacity and conflict misses. We even accumulate OBP translations into the kernel TSB. Another area for refinement is large page size support. We could use a secondary address space TSB to handle those. Signed-off-by: David S. Miller <davem@davemloft.net>
2005-09-19[SPARC64]: Move DCACHE_ALIASING_POSSIBLE define to asm/page.hDavid S. Miller
This showed that arch/sparc64/kernel/ptrace.c was not getting the define properly, and thus the code protected by this ifdef was never actually compiled before. So fix that too. Signed-off-by: David S. Miller <davem@davemloft.net>

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!
