[IA64] Move include/asm-ia64 to arch/ia64/include/asm

2008-08-01T17:21:21+00:00

After moving the the include files there were a few clean-ups: 1) Some files used #include , changed to 2) Some comments alerted maintainers to look at various header files to make matching updates if certain code were to be changed. Updated these comments to use the new include paths. 3) Some header files mentioned their own names in initial comments. Just deleted these self references. Signed-off-by: Tony Luck

[IA64] Multiple outstanding ptc.g instruction support

2008-04-04T18:05:59+00:00

According to SDM2.2, Itanium supports multiple outstanding ptc.g instructions. But current kernel function ia64_global_tlb_purge() uses a spinlock to serialize ptc.g instructions issued by multiple processors. This serialization might have scalability issue on a big SMP machine where many processors could purge TLB in parallel. The patch fixes this problem by issuing multiple ptc.g instructions in ia64_global_tlb_purge(). It also adds support for the "PALO" table to get a platform view of the max number of outstanding ptc.g instructions (which may be different from the processor view found from PAL_VM_SUMMARY). PALO specification can be found at: http://www.dig64.org/home/DIG64_PALO_R1_0.pdf spinaphore implementation by Matthew Wilcox. Signed-off-by: Fenghua Yu Signed-off-by: Tony Luck

[IA64] make flush_tlb_kernel_range() an inline function

2007-12-19T20:30:30+00:00

This fixes an unused variable warning in mm/vmalloc.c. Tony: also fix resulting fallout in uncached.c with a typo in args to flush_tlb_kernel_range(). Signed-off-by: Jan Beulich Signed-off-by: Tony Luck

remove unused flush_tlb_pgtables

2007-10-19T18:53:34+00:00

Nobody uses flush_tlb_pgtables anymore, this patch removes all remaining traces of it from all archs. Signed-off-by: Benjamin Herrenschmidt Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[IA64] Optional method to purge the TLB on SN systems

2007-05-08T21:50:43+00:00

This patch adds an optional method for purging the TLB on SN IA64 systems. The change should not affect any non-SN system. Signed-off-by: Jack Steiner Signed-off-by: Tony Luck

[IA64] Use bitmaps for efficient context allocation/free

2005-10-31T22:36:05+00:00

Corrects the very inefficent method of finding free context_ids in get_mmu_context(). Instead of walking the task_list of all processes, 2 bitmaps are used to efficently store and lookup state, inuse and needs flushing. The entire rid address space is now used before calling wrap_mmu_context and global tlb flushing. Special thanks to Ken and Rohit for their review and modifications in using a bit flushmap.

Linux-2.6.12-rc2

2005-04-16T22:20:36+00:00

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!
