Message-ID: <155402878327.25983.14339659161296384728.tglx@nanos.tec.linutronix.de>
Date: Sun, 31 Mar 2019 10:39:43 -0000

Subject: [GIT pull] perf updates for 5.1
Linus,
please pull the latest perf-urgent-for-linus git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-urgent-for-linus
up to: 22261fdf68f2 ("Merge tag 'perf-urgent-for-mingo-5.1-20190329' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent")
Perf tooling related fixes:
Core libraries:
- Fix max perf_event_attr.precise_ip detection.
- Fix parser error for uncore event alias
- Fixup ordering of kernel maps after obtaining the main kernel map address.
Intel PT:
- Fix TSC slip where A TSC packet can slip past MTC packets so that the
timestamp appears to go backwards.
- Fixes for exported-sql-viewer GUI conversion to python3.
ARM coresight:
- Fix the build by adding a missing case value for enumeration value introduced
in newer library, that now is the required one.
tool headers:
- Syncronize kernel headers with the kernel, getting new io_uring and
pidfd_send_signal syscalls so that 'perf trace' can handle them.
Thanks,
tglx
