- Introduce a errno code to string facility to allow tools such as 'perf trace' to support multi-arch perf.data decoding/beautifying, uses errno header files copied from the kernel, this allows removing the need for audit-libs in arches generating its syscall tables from the kernel sources, so far x86 and s/390 (Hendrik Brueckner) - Intel-PT/BTS sample synthesizing fixes (Adrian Hunter) - Intel vendor event JSON updates for the Broadwell, BroadwellDE, BroadwellX, Goldmont, Haswell, HaswellX, IvyBridge, IvyBridge, IvyTown, IvyTown, Silvermont, Skylake and SkylakeX architectures. (Andi Kleen) - Use ui__error() to have --field error handling messages not to disappear due to TUI exit cleanup (Arnaldo Carvalho de Melo) - Don't warn about unavailability of builtin clang in 'perf trace', just continue fallbacking to using the external toolchain (Arnaldo Carvalho de Melo) - Move conditional O_CLOEXEC define to util.h to keep the build working on older distros where that is not available now that this define will be used in more source files (Arnaldo Carvalho de Melo) - Using O_CLOEXEC in do_open() to avoid having too many open files when using 'perf script' from the 'perf report' TUI scripts browser (Wang YanQing) - Add 'perf trace --print-sample' to help in debugging the printing of timestamp calculations, for instance (Arnaldo Carvalho de Melo) - Do not print from time delta for interrupted syscall lines in 'perf trace' (those ending with '...') just print the total syscall duration at raw_syscalls:sys_exit time (Arnaldo Carvalho de Melo) - Beautify FUTEX_BITSET_MATCH_ANY in the futex syscall in 'perf trace' (Arnaldo Carvalho de Melo) - Display EXTRA features for 'make VF=1' build (Jiri Olsa) - Add support for CoreSight trace decoding by making the perf tools use the external openCSD (Mathieu Poirier, Tor Jeremiassen) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEELb9bqkb7Te0zijNb1lAW81NSqkAFAlppqAAACgkQ1lAW81NS qkCK6A/8DJx1ua5X+WQ2W2pf/5le5HFihiLw3PEA54b77MVIuV1FS0+/nzSzgK3h KtMGXnDQqrLET9mqFZHQ3CC+5TIR2fJbg1CAj8p8sBFeSU9mztcsO1ogi1GdAA/q PGyXJI9/n/MkiMKVlQRAHADXRg3ysrLplJJ+m9HDAPx6BR0OSts0Nqo5DgJF38s9 6qpHK1VFqSudBsl08MRPjtZXDZsFpFllgclw9aw7CW1T7y/UxwtYR9F8e8t/gdMS m4mbYwmNicaZ+TAN/tKZ1aewa6FIBdtwK42kQlbpF7vg/2foU1OPUIIebjJmDs0b qkSZUQcN5aBIqwdnMyB5YzJAfTgA4SEogPA0n9YqIQwRA7Wbgw2hsg6UxOJM+uJO ax4IiHdcGDodhPjdlIMCUEJmPZeZiL3WvpIjwodQCrhIA1JplWIaFMjCgaAlMmYL T0s8CGL0VvMtZP+0NGAS95WcLzjK0N9b4PpaZB6Nklgh9ArZ4cBogN1tt0IyeoWl l+4TxZhYzXvtWQwDgRnStoYEht0VqG6hJH5w9T/nttAGSh7z6xrQjkgzrXbklI7L y0RswNoIDJ0eBgvUzDl1gmc+MVaMoX1GfVRFnZYiRHli+nTWIEsZ2l+1RDA4Aoxv r0GhBCSIghM2hwsZQCjhfXEig9yacFrWCGR1492t0rg9u3FLbIw= =Zg7u -----END PGP SIGNATURE----- Merge tag 'perf-core-for-mingo-4.16-20180125' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo: - Introduce a errno code to string facility to allow tools such as 'perf trace' to support multi-arch perf.data decoding/beautifying, uses errno header files copied from the kernel, this allows removing the need for audit-libs in arches generating its syscall tables from the kernel sources, so far x86 and s/390 (Hendrik Brueckner) - Intel-PT/BTS sample synthesizing fixes (Adrian Hunter) - Intel vendor event JSON updates for the Broadwell, BroadwellDE, BroadwellX, Goldmont, Haswell, HaswellX, IvyBridge, IvyBridge, IvyTown, IvyTown, Silvermont, Skylake and SkylakeX architectures.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
