grub2/0195-Use-grub-file-to-figure-out-whether-multiboot2-shoul.patch
Peter Jones 81987f4958 Update grub2 for f28
- Try to fix things for new compiler madness.
  I really don't know why gcc decided __attribute__((packed)) on a "typedef
  struct" should imply __attribute__((align (1))) and that it should have a
  warning that it does so.  The obvious behavior would be to keep the alignment
  of the first element unless it's used in another object or type that /also/
  hask the packed attribute.  Why should it change the default alignment at
  all?
- Merge in the BLS patches Javier and I wrote.
- Attempt to fix pmtimer initialization failures to not be super duper slow.

Subject: [PATCH 195/206] Use grub-file to figure out whether multiboot2 should
be used for Xen.gz
The multiboot2 is much more preferable than multiboot. Especiall
if booting under EFI where multiboot does not have the functionality
to pass ImageHandler.
