Pull perf fixes from Thomas Gleixner: "A pile of perf fixes: Kernel side: - AMD uncore driver: Replace the open coded sanity check with the core variant, which provides the correct error code and also leaves a hint in dmesg Tooling: - Fix the stdio input handling with glibc versions >= 2.28 - Unbreak the futex-wake benchmark which was reduced to 0 test threads due to the conversion to cpumaps - Initialize sigaction structs before invoking sys_sigactio() - Plug the mapfile memory leak in perf jevents - Fix off by one relative directory includes - Fix an undefined string comparison in perf diff" * tag 'perf-urgent-2020-03-15' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: perf/amd/uncore: Replace manual sampling check with CAP_NO_INTERRUPT flag tools: Fix off-by 1 relative directory includes perf jevents: Fix leak of mapfile memory perf bench: Clear struct sigaction before sigaction() syscall perf bench futex-wake: Restore thread count default to online CPU count perf top: Fix stdio interface input handling with glibc 2.28+ perf diff: Fix undefined string comparision spotted by clang's -Wstring-compare perf symbols: Don't try to find a vmlinux file when looking for kernel modules perf bench: Share some global variables to fix build with gcc 10 perf parse-events: Use asprintf() instead of strncpy() to read tracepoint files perf env: Do not return pointers to local variables perf tests bp_account: Make global variable static
