Pull x86 fixes from Thomas Gleixner:
"A set of x86 fixes and functional updates:
- Prevent stale huge I/O TLB mappings on 32bit. A long standing bug
which got exposed by KPTI support for 32bit
- Prevent bogus access_ok() warnings in arch_stack_walk_user()
- Add display quirks for Lenovo devices which have height and width
swapped
- Add the missing CR2 fixup for 32 bit async pagefaults. Fallout of
the CR2 bug fix series.
- Unbreak handling of force enabled HPET by moving the 'is HPET
counting' check back to the original place.
- A more accurate check for running on a hypervisor platform in the
MDS mitigation code. Not perfect, but more accurate than the
previous one.
- Update a stale and confusing comment vs. IRQ stacks"

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.
