Linus Torvalds 05017fed92 - Make retbleed mitigations 64-bit only (32-bit will need a bit more
work if even needed, at all).
 
 - Prevent return thunks patching of the LKDTM modules as it is not needed there
 
 - Avoid writing the SPEC_CTRL MSR on every kernel entry on eIBRS parts
 
 - Enhance error output of apply_returns() when it fails to patch a return thunk
 
 - A sparse fix to the sev-guest module
 
 - Protect EFI fw calls by issuing an IBPB on AMD

Pull x86 fixes from Borislav Petkov:
 "A couple more retbleed fallout fixes.

  It looks like their urgency is decreasing so it seems like we've
  managed to catch whatever snafus the limited -rc testing has exposed.
  Maybe we're getting ready... :)

   - Make retbleed mitigations 64-bit only (32-bit will need a bit more
     work if even needed, at all).

   - Prevent return thunks patching of the LKDTM modules as it is not
     needed there

   - Avoid writing the SPEC_CTRL MSR on every kernel entry on eIBRS
     parts

   - Enhance error output of apply_returns() when it fails to patch a
     return thunk

   - A sparse fix to the sev-guest module

   - Protect EFI fw calls by issuing an IBPB on AMD"

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.
