This series adds the ability to use the entire PE image space for
decompression, provides the preferred address to the PE loader via the
header, and finally restricts efi_relocate_kernel to cases where we
really need it rather than whenever we were loaded at something other
than preferred address.

Based on tip:efi/core + the cleanup series just posted [1]
[1] https://lore.kernel.org/linux-efi/20200301230436.2246909-1-nivedita@alum.mit.edu/

Arvind Sankar (5):
  x86/boot/compressed/32: Save the output address instead of
    recalculating it
  efi/x86: Decompress at start of PE image load address
  efi/x86: Add kernel preferred address to PE header
  efi/x86: Remove extra headroom for setup block
  efi/x86: Don't relocate the kernel unless necessary
