Pull x86 entry code updates from Thomas Gleixner:
"More consolidation and correctness fixes for the debug exception:
- Ensure BTF synchronization under all circumstances
- Distangle kernel and user mode #DB further
- Get ordering vs. the debug notifier correct to make KGDB work more
reliably.
- Cleanup historical gunk and make the code simpler to understand"

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.
