Linus,

Please pull the latest efi-core-for-linus git tree from:

# HEAD: ac6119e7f25b842fc061e8aec88c4f32d3bc28ef efi/x86: Disable instrumentation in the EFI runtime handling code

The main changes in this cycle were:

- Cleanup of the GOP [graphics output] handling code in the EFI stub
- Complete refactoring of the mixed mode handling in the x86 EFI stub
- Overhaul of the x86 EFI boot/runtime code
- Increase robustness for mixed mode code
- Add the ability to disable DMA at the root port level in the EFI stub
- Get rid of RWX mappings in the EFI memory map and page tables, where possible
- Move the support code for the old EFI memory mapping style into its only
user, the SGI UV1+ support code.
- plus misc fixes, updates, smaller cleanups.

- And due to interactions with the RWX changes, another round of PAT
cleanups make a guest appearance via the EFI tree - with no side
effects intended.

Thanks,

Ingo
