Merge tag 'perf-tools-fixes-for-v5.19-2022-07-02' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
Pull perf tools fixes from Arnaldo Carvalho de Melo:
- BPF program info linear (BPIL) data is accessed assuming 64-bit
alignment resulting in undefined behavior as the data is just byte
aligned. Fix it, Found using -fsanitize=undefined.
- Fix 'perf offcpu' build on old kernels wrt task_struct's
state/__state field.
- Fix perf_event_attr.sample_type setting on the 'offcpu-time' event
synthesized by the 'perf offcpu' tool.
- Don't bail out when synthesizing PERF_RECORD_ events for pre-existing
threads when one goes away while parsing its procfs entries.
- Don't sort the task scan result from /proc, its not needed and
introduces bugs when the main thread isn't the first one to be
processed.
- Fix uninitialized 'offset' variable on aarch64 in the unwind code.
- Sync KVM headers with the kernel sources.
