Pull x86 fixes from Borislav Petkov:

 - Add a terminating zero end-element to the array describing AMD CPUs
   affected by erratum 1386 so that the matching loop actually
   terminates instead of going off into the weeds

 - Update the boot protocol documentation to mention the fact that the
   preferred address to load the kernel to is considered in the
   relocatable kernel case too

 - Flush the memory buffer containing the microcode patch after applying
   microcode on AMD Zen1 and Zen2, to avoid unnecessary slowdowns

 - Make sure the PPIN CPU feature flag is cleared on all CPUs if PPIN
   has been disabled
