This is another rebase, on top of mainline now (don't need the asm-generic tree), and without any x86 or membarrier changes. This makes the series far smaller and more manageable and without the controversial bits. Thanks, Nick Nicholas Piggin (5): lazy tlb: introduce lazy mm refcount helper functions lazy tlb: allow lazy tlb mm switching to be configurable lazy tlb: shoot lazies, a non-refcounting lazy tlb option powerpc: use lazy mm refcount helper functions powerpc/64s: enable MMU_LAZY_TLB_SHOOTDOWN arch/Kconfig | 30 ++++++++++ arch/arm/mach-rpc/ecard.c | 2 +- arch/powerpc/Kconfig | 1 + arch/powerpc/kernel/smp.c | 2 +- arch/powerpc/mm/book3s64/radix_tlb.c | 4 +- fs/exec.c | 4 +- include/linux/sched/mm.h | 20 +++++++ kernel/cpu.c | 2 +- kernel/exit.c | 2 +- kernel/fork.c | 52 ++++++++++++++++ kernel/kthread.c | 11 ++-- kernel/sched/core.c | 88 ++++++++++++++++++++-------- kernel/sched/sched.h | 4 +- 13 files changed, 184 insertions(+), 38 deletions(-) -- 2.23.0
