operations require VMM cooperation, even in CoCo environments
where the VMM is untrusted. While it's _possible_ that memory
pressure could trigger the new warning, the odds are that a
guest would only see this from an attacking VMM.
* Simplify page fault code by re-enabling interrupts unconditionally
* Avoid truncation issues when pfns are passed in to
pfn_to_kaddr() with small (<64-bit) types.

Pull x86 mm updates from Dave Hansen:
- Add a warning when memory encryption conversions fail. These
operations require VMM cooperation, even in CoCo environments where
the VMM is untrusted. While it's _possible_ that memory pressure
could trigger the new warning, the odds are that a guest would only
see this from an attacking VMM.
- Simplify page fault code by re-enabling interrupts unconditionally
- Avoid truncation issues when pfns are passed in to pfn_to_kaddr()
with small (<64-bit) types.

x86/mm/cpa: Warn for set_memory_XXcrypted() VMM fails
x86/mm: Get rid of conditional IF flag handling in page fault path
x86/mm: Ensure input to pfn_to_kaddr() is treated as a 64-bit type

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.
