grub2/0042-sparc64-Don-t-use-devspec-to-determine-the-OBP-path.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 042/206] sparc64: Don't use devspec to determine the OBP path
Don't use devspec to determine the OBP path on SPARC hardware. Within all
versions of Linux on SPARC, the devspec returns one of three values:
"none", "vnet-port", or "vdisk". Unlike on PPC, none of these values
are useful in determining the OBP path.
Before this patch grub-ofpathname always returned the wrong value
for a virtual disk. For example:
% grub-ofpathname /dev/vdiskc2
vdisk/disk@2:b
After this patch it now returns the correct value:
% grub-ofpathname /dev/vdiskc2
/virtual-devices@100/channel-devices@200/disk@2:b
