The tlbie can # race with an mtpid (move to PID register, essentially MMU context # switch) on another thread of the core, which can cause stores to # continue to go to a page after it's unmapped. # # - A fix in our KVM code to add a missing barrier, the lack of which # has been observed to cause missed IPIs and subsequently stuck CPUs # in the host. # # - A change to the way we initialise PCR (Processor Compatibility # Register) to make it forward compatible with future CPUs. # # - On some older PowerVM systems our H_BLOCK_REMOVE support could # oops, fix it to detect such systems and fallback to the old # invalidation method. # # - A fix for an oops seen on some machines when using KASAN on 32-bit. # # - A handful of other minor fixes, and two new selftests. # # Thanks to: Alistair Popple, Aneesh Kumar K.V, Christophe Leroy, # Gustavo Romero, Joel Stanley, Jordan Niethe, Laurent Dufour, Michael # Roth, Oliver O'Halloran" # # * tag 'powerpc-5.4-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux: # powerpc/eeh: Fix eeh eeh_debugfs_break_device() with SRIOV devices # powerpc/nvdimm: use H_SCM_QUERY hcall on H_OVERLAP error # powerpc/nvdimm: Use HCALL error as the return value # selftests/powerpc: Add test case for tlbie vs mtpidr ordering issue # powerpc/mm: Fixup tlbie vs mtpidr/mtlpidr ordering issue on POWER9 # powerpc/book3s64/radix: Rename CPU_FTR_P9_TLBIE_BUG feature flag # powerpc/book3s64/mm: Don't do tlbie fixup for some hardware revisions # powerpc/pseries: Call H_BLOCK_REMOVE when supported # powerpc/pseries: Read TLB Block Invalidate Characteristics # KVM: PPC: Book3S HV: use smp_mb() when setting/clearing host_ipi flag # powerpc/mm: Fix an Oops in kasan_mmu_init() # powerpc/mm: Add a helper to select PAGE_KERNEL_RO or PAGE_READONLY # powerpc/64s: Set reserved PCR bits # powerpc: Fix definition of PCR bits to work with old binutils # powerpc/book3s64/radix: Remove WARN_ON in destroy_context() # powerpc/tm: Add tm-poison test # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 a2953204b576ea3ba4afd07b917811d50fc49778 # < make -s -j 120 ARCH=arm64 O=/kisskb/build/linus_arm64-allmodconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- allmodconfig # make -s -j 120 ARCH=arm64 O=/kisskb/build/linus_arm64-allmodconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- arch/arm64/Makefile:27: ld does not support --fix-cortex-a53-843419;
