Hi Linus,

Please pull a single x86/urgent change for 6.4-rc4.  This works around
and issue where the INVLPG instruction may miss invalidating kernel
TLB entries.  I do expect an eventual microcode fix for this.  When
the microcode version numbers are known, we can circle back around and
add them the model table to disable this workaround.
