    SRU Justification

    Impact:
       The upstream process for stable tree updates is quite similar
       in scope to the Ubuntu SRU process, e.g., each patch has to
       demonstrably fix a bug, and each patch is vetted by upstream
       by originating either directly from a mainline/stable Linux tree or
       a minimally backported form of that patch. The following upstream
       stable patches should be included in the Ubuntu kernel:

       v5.4.250 upstream stable release
       from git://git.kernel.org/

Linux 5.4.250
x86/cpu/amd: Add a Zenbleed fix
x86/cpu/amd: Move the errata checking functionality up
x86/microcode/AMD: Load late on both threads too
