I should have the maintainers' acks in place. # # Summary: # # - Spectre v4 mitigation (Speculative Store Bypass Disable) support # for arm64 using SMC firmware call to set a hardware chicken bit # # - ACPI PPTT (Processor Properties Topology Table) parsing support and # enable the feature for arm64 # # - Report signal frame size to user via auxv (AT_MINSIGSTKSZ). The # primary motivation is Scalable Vector Extensions which requires # more space on the signal frame than the currently defined # MINSIGSTKSZ # # - ARM perf patches: allow building arm-cci as module, demote # dev_warn() to dev_dbg() in arm-ccn event_init(), miscellaneous # cleanups # # - cmpwait() WFE optimisation to avoid some spurious wakeups # # - L1_CACHE_BYTES reverted back to 64 (for performance reasons that # have to do with some network allocations) while keeping # ARCH_DMA_MINALIGN to 128. cache_line_size() returns the actual # hardware Cache Writeback Granule # # - Turn LSE atomics on by default in Kconfig # # - Kernel fault reporting tidying # # - Some #include and miscellaneous cleanups" # # * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (53 commits) # arm64: Fix syscall restarting around signal suppressed by tracer # arm64: topology: Avoid checking numa mask for scheduler MC selection # ACPI / PPTT: fix build when CONFIG_ACPI_PPTT is not enabled # arm64: cpu_errata: include required headers # arm64: KVM: Move VCPU_WORKAROUND_2_FLAG macros to the top of the file # arm64: signal: Report signal frame size to userspace via auxv # arm64/sve: Thin out initialisation sanity-checks for sve_max_vl # arm64: KVM: Add ARCH_WORKAROUND_2 discovery through ARCH_FEATURES_FUNC_ID # arm64: KVM: Handle guest's ARCH_WORKAROUND_2 requests # arm64: KVM: Add ARCH_WORKAROUND_2 support for guests # arm64: KVM: Add HYP per-cpu accessors # arm64: ssbd: Add prctl interface for per-thread mitigation # arm64: ssbd: Introduce thread flag to control userspace mitigation # arm64: ssbd: Restore mitigation status on CPU resume # arm64: ssbd: Skip apply_ssbd if not using dynamic mitigation # arm64: ssbd: Add global mitigation state accessor # arm64: Add 'ssbd' command-line option # arm64: Add ARCH_WORKAROUND_2 probing # arm64: Add per-cpu infrastructure to call ARCH_WORKAROUND_2 # arm64: Call ARCH_WORKAROUND_2 on transitions between EL0 and EL1 # ... # < /opt/cross/kisskb/arcompact-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc-gcc --version # < git log --format=%s --max-count=1 410feb75de245664d66bc05ab2e2412751d10acf # < make -s -j 48 ARCH=arc O=/kisskb/build/linus_axs101_defconfig_arcompact CROSS_COMPILE=/opt/cross/kisskb/arcompact-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc- axs101_defconfig # Added to kconfig CONFIG_INITRAMFS_SOURCE="" # yes \n | make -s -j 48 ARCH=arc O=/kisskb/build/linus_axs101_defconfig_arcompact CROSS_COMPILE=/opt/cross/kisskb/arcompact-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 48 ARCH=arc O=/kisskb/build/linus_axs101_defconfig_arcompact CROSS_COMPILE=/opt/cross/kisskb/arcompact-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc- In file included from /kisskb/src/include/asm-generic/bug.h:18:0, from /kisskb/src/arch/arc/include/asm/bug.h:32, from /kisskb/src/include/linux/bug.h:5, from /kisskb/src/include/linux/mmdebug.h:5, from /kisskb/src/include/linux/gfp.h:5, from /kisskb/src/include/linux/slab.h:15, from /kisskb/src/mm/nobootmem.c:14: /kisskb/src/mm/nobootmem.c: In function '__free_pages_memory': /kisskb/src/include/linux/kernel.h:812:29: warning: comparison of distinct pointer types lacks a cast [enabled by default] (!!(sizeof((typeof(x) *)1 == (typeof(y) *)1))) ^ /kisskb/src/include/linux/kernel.h:826:4: note: in expansion of macro '__typecheck' (__typecheck(x, y) && __no_side_effects(x, y)) ^ /kisskb/src/include/linux/kernel.h:836:24: note: in expansion of macro '__safe_cmp' __builtin_choose_expr(__safe_cmp(x, y), \ ^ /kisskb/src/include/linux/kernel.h:845:19: note: in expansion of macro '__careful_cmp' #define min(x, y) __careful_cmp(x, y, <) ^ /kisskb/src/mm/nobootmem.c:104:11: note: in expansion of macro 'min' order = min(MAX_ORDER - 1UL, __ffs(start)); ^ /kisskb/src/net/ipv4/tcp_input.c: In function 'tcp_data_queue': /kisskb/src/net/ipv4/tcp_input.c:4296:49: warning: array subscript is above array bounds [-Warray-bounds] tp->selective_acks[i-1] = tp->selective_acks[i]; ^ /kisskb/src/net/xfrm/xfrm_policy.c: In function '__xfrm_policy_check': /kisskb/src/net/xfrm/xfrm_policy.c:2377:15: warning: array subscript is above array bounds [-Warray-bounds] if (sp->xvec[k]->props.mode != XFRM_MODE_TRANSPORT) { ^ Completed OK # rm -rf /kisskb/build/linus_axs101_defconfig_arcompact # Build took: 0:01:33.502363
