Linus Torvalds dfd437a257 arm64 updates for 5.3: ... - arm64 support for syscall emulation via PTRACE_SYSEMU{,_SINGLESTEP} - Wire up VM_FLUSH_RESET_PERMS for arm64, allowing the core code to manage the permissions of executable vmalloc regions more strictly - Slight performance improvement by keeping softirqs enabled while touching the FPSIMD/SVE state (kernel_neon_begin/end) - Expose a couple of ARMv8.5 features to user (HWCAP): CondM (new XAFLAG and AXFLAG instructions for floating point comparison flags manipulation) and FRINT (rounding floating point numbers to integers) - Re-instate ARM64_PSEUDO_NMI support which was previously marked as BROKEN due to some bugs (now fixed) - Improve parking of stopped CPUs and implement an arm64-specific panic_smp_self_stop() to avoid warning on not being able to stop secondary CPUs during panic - perf: enable the ARM Statistical Profiling Extensions (SPE) on ACPI platforms - perf: DDR performance monitor support for iMX8QXP - cache_line_size() can now be set from DT or ACPI/PPTT if provided to cope with a system cache info not exposed via the CPUID registers - Avoid warning on hardware cache line size greater than ARCH_DMA_MINALIGN if the system is fully coherent - arm64 do_page_fault() and hugetlb cleanups - Refactor set_pte_at() to avoid redundant READ_ONCE(*ptep) - Ignore ACPI 5.1 FADTs reported as 5.0 (infer from the 'arm_boot_flags' introduced in 5.1) - CONFIG_RANDOMIZE_BASE now enabled in defconfig - Allow the selection of ARM64_MODULE_PLTS, currently only done via RANDOMIZE_BASE (and an erratum workaround), allowing modules to spill over into the vmalloc area - Make ZONE_DMA32 configurable -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE5RElWfyWxS+3PLO2a9axLQDIXvEFAl0eHqcACgkQa9axLQDI XvFyNA/+L+bnkz8m3ncydlqqfXomQn4eJJVQ8Uksb0knJz+1+3CUxxbO4ry4jXZN fMkbggYrDPRKpDbsUl0lsRipj7jW9bqan+N37c3SWqCkgb6HqDaHViwxdx6Ec/Uk gHudozDSPh/8c7hxGcSyt/CFyuW6b+8eYIQU5rtIgz8aVY2BypBvS/7YtYCbIkx0 w4CFleRTK1zXD5mJQhrc6jyDx659sVkrAvdhf6YIymOY8nBTv40vwdNo3beJMYp8 Po/+0Ixu+VkHUNtmYYZQgP/AGH96xiTcRnUqd172JdtRPpCLqnLqwFokXeVIlUKT KZFMDPzK+756Ayn4z4huEePPAOGlHbJje8JVNnFyreKhVVcCotW7YPY/oJR10bnc eo7yD+DxABTn+93G2yP436bNVa8qO1UqjOBfInWBtnNFJfANIkZweij/MQ6MjaTA o7KtviHnZFClefMPoiI7HDzwL8XSmsBDbeQ04s2Wxku1Y2xUHLx4iLmadwLQ1ZPb lZMTZP3N/T1554MoURVA1afCjAwiqU3bt1xDUGjbBVjLfSPBAn/25IacsG9Li9AF 7Rp1M9VhrfLftjFFkB2HwpbhRASOxaOSx+EI3kzEfCtM2O9I1WHgP3rvCdc3l0HU tbK0/IggQicNgz7GSZ8xDlWPwwSadXYGLys+xlMZEYd3pDIOiFc= =0TDT -----END PGP SIGNATURE----- Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Catalin Marinas: -
