Pull misc x86 fixes and updates from Ingo Molnar:

 - Fix a large number of x86 Kconfig dependency and help text accuracy
   bugs/problems, by Mateusz Jończyk and David Heideberg

 - Fix a VM_PAT interaction with fork() crash. This also touches core
   kernel code

 - Fix an ORC unwinder bug for interrupt entries

 - Fixes and cleanups

 - Fix an AMD microcode loader bug that can promote verification
   failures into success

 - Add early-printk support for MMIO based UARTs on an x86 board that
   had no other serial debugging facility and also experienced early
   boot crashes
