Pull powerpc fix from Michael Ellerman:
 "Just one fix to correctly return SEGV_ACCERR when we take a SEGV on a
  mapped region. The bug was introduced in the refactoring of the page
  fault handler we did in the previous release.

  Thanks to John Sperbeck"

Pull  more x86 pti fixes from Thomas Gleixner:
 "Another small stash of fixes for fallout from the PTI work:

   - Fix the modules vs. KASAN breakage which was caused by making
     MODULES_END depend of the fixmap size. That was done when the cpu
     entry area moved into the fixmap, but now that we have a separate
     map space for that this is causing more issues than it solves.

   - Use the proper cache flush methods for the debugstore buffers as
     they are mapped/unmapped during runtime and not statically mapped
     at boot time like the rest of the cpu entry area.

   - Make the map layout of the cpu_entry_area consistent for 4 and 5
     level paging and fix the KASLR vaddr_end wreckage.

   - Use PER_CPU_EXPORT for per cpu variable and while at it unbreak
     nvidia gfx drivers by dropping the GPL export. The subject line of
     the commit tells it the other way around, but I noticed that too
     late.

   - Fix the ASM alternative macros so they can be used in the middle of
     an inline asm block.

   - Rename the BUG_CPU_INSECURE flag to BUG_CPU_MELTDOWN so the attack
     vector is properly identified. The Spectre mitigations will come
     with their own bug bits later"

Pull EFI updates from Thomas Gleixner:

 - A fix for a add_efi_memmap parameter regression which ensures that
   the parameter is parsed before it is used.

 - Reinstate the virtual capsule mapping as the cached copy turned out
   to break Quark and other things

 - Remove Matt Fleming as EFI co-maintainer. He stepped back a few days
   ago. Thanks Matt for all your great work!
