Sean Christopherson ec495f2ab1 KVM: Write the per-page "segment" when clearing (part of) a guest page 
Pass "seg" instead of "len" when writing guest memory in kvm_clear_guest(),
as "seg" holds the number of bytes to write for the current page, while
"len" holds the total bytes remaining.

Luckily, all users of kvm_clear_guest() are guaranteed to not cross a page
boundary, and so the bug is unhittable in the current code base.

Fixes: 2f5414423e ("KVM: remove kvm_clear_guest_page")

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.
