perf stat:
- Keep the '/' event modifier separator in fallback, for example when
fallbacking from 'cpu/cpu-cycles/' to user level only, where it should
become 'cpu/cpu-cycles/u' and not 'cpu/cpu-cycles/:u' (Jiri Olsa)
- Fix PMU events parsing rule, improving error reporting for
invalid events (Jiri Olsa)
- Disable write_backward and other event attributes for !group
events in a group, fixing, for instance this group: '{cycles,msr/aperf/}:S'
that has leader sampling (:S) and where just the 'cycles',
the leader event, should have the write_backward attribute
set, in this case it all fails because the PMU where 'msr/aperf/'
lives doesn't accepts write_backward style sampling (Jiri Olsa)
- Only fall back group read for leader (Kan Liang)
- Fix core PMU alias list for X86 platform (Kan Liang)
- Print out hint for mixed PMU group error (Kan Liang)
- Fix duplicate PMU name for interval print (Kan Liang)
Core:
- Set main kernel end address properly when reading kernel and
module maps (Namhyung Kim)
perf mem:
- Fix incorrect entries and add missing man options (Sangwon Hong)
s/390:
- Remove s390 specific strcmp_cpuid_cmp function (Thomas Richter)
- Adapt 'perf test' case record+probe_libc_inet_pton.sh for s390
- Fix s390 undefined record__auxtrace_init() return value in
'perf record' (Thomas Richter)

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
