Andrew, since the arch patches depend on the base patch, maybe the mm tree is the right one? I have acks/reviews for the s390/x86 part. As CONFIG_DEBUG_PAGEALLOC can be enabled/disabled via kernel parameters we can optimize some cases by checking the enablement state. I have done s390 and x86 as examples. s390 should be ok, I tested several combinations, x86 seems to work as well. Power can probably do the same, Michael/Ben? I am not sure about sparc. Sparc seems to allocate the TSB buffer really early. David? V2->V3: - Fix whitespace/indent breakage in s390 patch V1->V2: - replace DEBUG_PAGEALLOC(disabled/enabled) with DEBUG_PAGEALLOC dump_stack for s390/x86 - add /* CONFIG_DEBUG_PAGEALLOC */ to else and endif Christian Borntraeger (3): mm: provide debug_pagealloc_enabled() without CONFIG_DEBUG_PAGEALLOC x86: query dynamic DEBUG_PAGEALLOC setting s390: query dynamic DEBUG_PAGEALLOC setting arch/s390/kernel/dumpstack.c | 6 +++--- arch/s390/mm/vmem.c | 10 ++++------ arch/x86/kernel/dumpstack.c | 5 ++--- arch/x86/mm/init.c | 7 ++++--- arch/x86/mm/pageattr.c | 14 ++++---------- include/linux/mm.h | 9 +++++++-- 6 files changed, 24 insertions(+), 27 deletions(-) -- 2.3.0 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
