mainlining shenanigans
100198322b
This new PR_SET_VMA value isn't in sequence with all the other prctl
arguments and instead uses a big, 0x prefixed hex number: 0x53564d41 (S V M A).
This makes it harder to generate a string table as it would be rather
sparse, so make the regexp more stricter to avoid catching those.
A followup patch for 'perf trace' to cope with such oddities will be
needed, but then its a matter for the next merge window.
The next patch will update the prctl.h file to cope with this perf build

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.
