I plan to send a pull request to Russell targetting 3.12 pending no further feedback. Cheers, Will Will Deacon (12): ARM: mm: remove redundant dsb() prior to range TLB invalidation ARM: tlb: don't perform inner-shareable invalidation for local TLB ops ARM: tlb: don't bother with barriers for branch predictor maintenance ARM: tlb: don't perform inner-shareable invalidation for local BP ops ARM: barrier: allow options to be passed to memory barrier instructions ARM: tlb: reduce scope of barrier domains for TLB invalidation ARM: mm: use inner-shareable barriers for TLB and user cache operations ARM: spinlock: use inner-shareable dsb variant prior to sev instruction ARM: kvm: use inner-shareable barriers after TLB flushing ARM: mcpm: use -st dsb option prior to sev instructions ARM: l2x0: use -st dsb option for ordering writel_relaxed with unlock ARM: cacheflush: use -ishst dsb variant for ensuring flush completion arch/arm/common/mcpm_head.S | 2 +- arch/arm/common/vlock.S | 4 +- arch/arm/include/asm/assembler.h | 4 +- arch/arm/include/asm/barrier.h | 32 +++---- arch/arm/include/asm/cacheflush.h | 2 +- arch/arm/include/asm/spinlock.h | 2 +- arch/arm/include/asm/switch_to.h | 10 +++ arch/arm/include/asm/tlbflush.h | 181 +++++++++++++++++++++++++++++++------- arch/arm/kernel/smp_tlb.c | 10 +-- arch/arm/kvm/init.S | 2 +- arch/arm/kvm/interrupts.S | 4 +- arch/arm/mm/cache-l2x0.c | 2 +- arch/arm/mm/cache-v7.S | 4 +- arch/arm/mm/context.c | 6 +- arch/arm/mm/dma-mapping.c | 1 - arch/arm/mm/proc-v7.S | 2 +- arch/arm/mm/tlb-v7.S | 8 +- 17 files changed, 199 insertions(+), 77 deletions(-) -- 1.8.2.2
