Linus Torvalds db87114dcf - Explicitly disable the TSC deadline timer when going idle to address
some CPU errata in that area
 
 - Do not apply the Zenbleed fix on anything else except AMD Zen2 on the
   late microcode loading path
 
 - Clear CPU buffers later in the NMI exit path on 32-bit to avoid
   register clearing while they still contain sensitive data, for the
   RDFS mitigation
 
 - Do not clobber EFLAGS.ZF with VERW on the opportunistic SYSRET exit
   path on 32-bit
 
 - Fix parsing issues of memory bandwidth specification in sysfs for
   resctrl's memory bandwidth allocation feature
 
 - Other small cleanups and improvements

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 reStructuredText 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.
