- Fix a regression in the conversion of the 64-bit BookE interrupt entry to C.
- Fix KVM hosts running with the hash MMU since the recent KVM gfn changes.
- Fix a deadlock in our paravirt spinlocks when hcall tracing is enabled.
- Several fixes for oopses in our runtime code patching for security mitigations.
- A couple of minor fixes for the recent conversion of 32-bit interrupt entry/exit to C.
- Fix __get_user() causing spurious crashes in sigreturn due to a bad inline asm
constraint, spotted with GCC 11.
- A fix for the way we track IRQ masking state vs NMI interrupts when using the new scv
system call entry path.
- A couple more minor fixes.

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.
