Pull EFI fixes from Thomas Gleixner:
 "A set of EFI fixes:

   - Don't return a garbage screen info when EFI framebuffer is not
     available

   - Make the early EFI console work properly with wider fonts instead
     of drawing garbage

   - Prevent a memory buffer leak in allocate_e820()

   - Print the firmware error record properly so it can be decoded by
     users

   - Fix a symbol clash in the host tool build which only happens with
     newer compilers.

   - Add a missing check for the event log version of TPM which caused
     boot failures on several Dell systems due to an attempt to decode
     SHA-1 format with the crypto agile algorithm"
