Kdump will come later (requires updates to libfdt). # # - Optimisation of our dynamic CPU feature framework, so that all # detected features are enabled via a single stop_machine() # invocation # # - KPTI whitelisting of Cortex-A CPUs unaffected by Meltdown, so that # they can benefit from global TLB entries when KASLR is not in use # # - 52-bit virtual addressing for userspace (kernel remains 48-bit) # # - Patch in LSE atomics for per-cpu atomic operations # # - Custom preempt.h implementation to avoid unconditional calls to # preempt_schedule() from preempt_enable() # # - Support for the new 'SB' Speculation Barrier instruction # # - Vectorised implementation of XOR checksumming and CRC32 # optimisations # # - Workaround for Cortex-A76 erratum #1165522 # # - Improved compatibility with Clang/LLD # # - Support for TX2 system PMUS for profiling the L3 cache and DMC # # - Reflect read-only permissions in the linear map by default # # - Ensure MMIO reads are ordered with subsequent calls to Xdelay() # # - Initial support for memory hotplug # # - Tweak the threshold when we invalidate the TLB by-ASID, so that # mremap() performance is improved for ranges spanning multiple PMDs. # # - Minor refactoring and cleanups" # # * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (125 commits) # arm64: kaslr: print PHYS_OFFSET in dump_kernel_offset() # arm64: sysreg: Use _BITUL() when defining register bits # arm64: cpufeature: Rework ptr auth hwcaps using multi_entry_cap_matches # arm64: cpufeature: Reduce number of pointer auth CPU caps from 6 to 4 # arm64: docs: document pointer authentication # arm64: ptr auth: Move per-thread keys from thread_info to thread_struct # arm64: enable pointer authentication # arm64: add prctl control for resetting ptrauth keys # arm64: perf: strip PAC when unwinding userspace # arm64: expose user PAC bit positions via ptrace # arm64: add basic pointer authentication support # arm64/cpufeature: detect pointer authentication # arm64: Don't trap host pointer auth use to EL2 # arm64/kvm: hide ptrauth from guests # arm64/kvm: consistently handle host HCR_EL2 flags # arm64: add pointer authentication register bits # arm64: add comments about EC exception levels # arm64: perf: Treat EXCLUDE_EL* bit definitions as unsigned # arm64: kpti: Whitelist Cortex-A CPUs that don't implement the CSV3 field # arm64: enable per-task stack canaries # ... # < /opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux-gcc --version # < /opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux-ld --version # < git log --format=%s --max-count=1 5694cecdb092656a822287a6691aa7ce668c8160 # < make -s -j 10 ARCH=xtensa O=/kisskb/build/linus_xtensa-allmodconfig_xtensa CROSS_COMPILE=/opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux- allmodconfig drivers/staging/mt7621-dts/Kconfig:4:warning: 'BUILTIN_DTB' has wrong type.
