Linus Torvalds cab6d5b66b Merge branch 'akpm' (patches from Andrew)
Merge misc VM fixes from Andrew Morton:
 "A bunch of hotfixes, all affecting mm/.

  The two-patch series from Andrea may be controversial. This restores
  patches which were reverted in Dec 2018 due to a regression report [*].

  After extensive discussion it is evident that the problems which these
  patches solved were significantly more serious than the problems they
  introduced. I am told that major distros are already carrying these
  two patches for this reason"

[*] See

      https://lore.kernel.org/lkml/alpine.DEB.2.21.1812061343240.144733@chino.kir.corp.google.com/
      https://lore.kernel.org/lkml/alpine.DEB.2.21.1812031545560.161134@chino.kir.corp.google.com/

  for the google-specific issues brought up by David Rijentes. And as
  Andrew says:

    "I'm unaware of anyone else who will be adversely affected by this,
     and google already carries over a thousand kernel patches - another
     won't kill them.

     There has been sporadic discussion about fixing these things for
     real but it's clear that nobody apart from David is particularly
     motivated"

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.
