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.
