Sean Christopherson 368340a3c7 KVM: SVM: Invert user pointer casting in SEV {en,de}crypt helpers 
Invert the user pointer params for SEV's helpers for encrypting and
decrypting guest memory so that they take a pointer and cast to an
unsigned long as necessary, as opposed to doing the opposite.  Tagging a
non-pointer as __user is confusing and weird since a cast of some form
needs to occur to actually access the user data.  This also fixes Sparse
warnings triggered by directly consuming the unsigned longs, which are
"noderef" due to the __user tag.

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.
