Mainline Linux tree for various devices, only for fun :)

If me_huge_page meets a truncated but not yet freed hugepage, it won't be dissolved even if we hold the last refcnt. It's because the hugepage has NULL page_mapping while it's not anonymous hugepage too. Thus we lose the last chance to dissolve it into buddy to save healthy subpages. Remove PageAnon check to handle these hugepages too.

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.
