Barry Song 6434e69814 mm: arm64: fix the out-of-bounds issue in contpte_clear_young_dirty_ptes 
We are passing a huge nr to __clear_young_dirty_ptes() right now.  While
we should pass the number of pages, we are actually passing CONT_PTE_SIZE.
This is causing lots of crashes of MADV_FREE, panic oops could vary
everytime.

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 reStructuredText 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.
