Two hardware event flags on x86 platform has overshot PERF_EVENT_FLAG_ARCH (0x0000ffff). These flags are PERF_X86_EVENT_PEBS_LAT_HYBRID (0x20000) and PERF_X86_EVENT_AMD_BRS (0x10000). Lets expand PERF_EVENT_FLAG_ARCH mask to accommodate those flags, and also create room for two more in the future.

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.
