Linux kernel source tree
210b09fa42
A new bit PERF_CAPABILITIES[17] called "PEBS_TIMING_INFO" bit is added to indicated if PEBS supports to record timing information in a new "Retried Latency" field. Since KVM requires user can only set host consistent PEBS capabilities, otherwise the PERF_CAPABILITIES setting would fail, add pebs_timing_info into the "immutable_caps" to block host inconsistent PEBS configuration and cause errors. Opportunistically drop the anythread_deprecated bit. It isn't and likely never was a PERF_CAPABILITIES flag, the test's definition snuck in when the union was copy+pasted from the kernel's definition.

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 reStructuredText 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.
