Linus Torvalds f9e2bb42cf Some more perf tools fixes for v5.12:
- Avoid write of uninitialized memory when generating PERF_RECORD_MMAP* records.
 
 - Fix 'perf top' BPF support related crash with perf_event_paranoid=3 + kptr_restrict.
 
 - Validate raw event with sysfs exported format bits.
 
 - Fix waipid on SIGCHLD delivery bugs in 'perf daemon'.
 
 - Change to use bash for daemon test on Debian, where the default is dash and
   thus fails for use of bashisms in this test.
 
 - Fix memory leak in vDSO found using ASAN.
 
 - Remove now useless (due to the fact taht BPF now supports static vars)
   failing sub test "BPF relocation checker".
 
 - Fix auxtrace queue conflict.
 
 - Sync linux/kvm.h with the kernel sources.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

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.
