Alexey Dobriyan 17415606f9 tools/testing/selftests/proc/proc-pid-vm.c: test with vsyscall in mind
: selftests: proc: proc-pid-vm
: ========================================
: proc-pid-vm: proc-pid-vm.c:277: main: Assertion `rv == strlen(buf0)' failed.
: Aborted

Because the vsyscall mapping is enabled.  Read from vsyscall page to tell
if vsyscall is being used.

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.
