Masami Hiramatsu a58f4afe22 selftests: proc: Make va_max 1MB
[ Upstream commit 2f3571ea71311bbb2cbb9c3bbefc9c1969a3e889 ]

Currently proc-self-map-files-002.c sets va_max (max test address
of user virtual address) to 4GB, but it is too big for 32bit
arch and 1UL << 32 is overflow on 32bit long.
Also since this value should be enough bigger than vm.mmap_min_addr
(64KB or 32KB by default), 1MB should be enough.

Make va_max 1MB unconditionally.

README

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.
