The MM PAT bits touching mm/memory.c and include/linux/mm.h were reviewed and acked by Nick, the DMAR bits are part of a longer x2apic fix series from Suresh. (Jesse Cc:-ed) [ The sched.c bit is an odd one out: due to previous cpumask changes it developed a dependency/conflict on the cpumask tree which depended on the x86 tree. Should i have started a separate branch for it? I didnt want to merge the x86 tree into the scheduler tree. We had really excessive dependencies and cross-merges in this cycle around the x86 tree and i very much hope this is an exception - there's been too many infrastructure projects going on in parallel. Nothing of this scale will happen in the .31 cycle - with the TLB, APIC, percpu unification in this cycle we've modernized and unified the whole x86 infrastructure. Future work will interact a lot less. ] out-of-topic modifications in x86-stage-3-for-linus: ---------------------------------------------------- drivers/pci/dmar.c # fa4b57c: x86, dmar: use atomic allocations # 1531a6a: x86, dmar: start with sane state # eba67e5: x86, dmar: routines for disabling # 9d783ba: x86, x2apic: enable fault handlin # 0ac2491: x86, dmar: move page fault handli drivers/pci/intel-iommu.c # 1531a6a: x86, dmar: start with sane state # 9d783ba: x86, x2apic: enable fault handlin # 0ac2491: x86, dmar: move page fault handli drivers/pci/intr_remapping.c # fa4b57c: x86, dmar: use atomic allocations # 2e93456: x86, intr-remapping: fix free_irt # 1531a6a: x86, dmar: start with sane state # eba67e5: x86, dmar: routines for disabling # 9d783ba: x86, x2apic: enable fault handlin # 4c5502b: x86, x2apic: fix lock ordering du include/linux/dmar.h # 29b61be: x86, x2apic: cleanup ifdef CONFIG # 1531a6a: x86, dmar: start with sane state # 9d783ba: x86, x2apic: enable fault handlin include/linux/intel-iommu.h # eba67e5: x86, dmar: routines for disabling # 9d783ba: x86, x2apic: enable fault handlin include/linux/mm.h # 895791d: VM, x86, PAT: add a new vm flag t # 4bb9c5c: VM, x86, PAT: Change is_linear_pf kernel/sched.c # 7a46c59: cpuacct: reduce one NULL check in mm/memory.c # 895791d: VM, x86, PAT: add a new vm flag t # 4bb9c5c: VM, x86, PAT: Change is_linear_pf Known risks: - We had some boot regression trouble with the e820 changes, on systems with odd/small memory layouts: x86: fix e820_update_range() x86: make e820_update_range() handle small range update - The very-early-brk changes had several regressions along the way: x86: add brk allocation for very, very early allocations - The IO-APIC/APIC cleanups were relatively trouble-free, but that code is always a risk area. - No known regressions at the moment.
