Subject: [PATCH 0/3] x86, efi: EFI boot stub documentation

From: Matt Fleming <matt.fleming@...el.com>

Some people trying out the EFI stub have been confused about the
syntax for the initrd= option, so this series adds some information to
Documentation/x86. It also adds some helpful error messages, as
previously if the user specified an incorrect initrd filename the
machine just appeared to hang. Now at least it will print a message
saying that it couldn't open the file.

The first patch is actually a bug fix for an issue where the wrong
loop counter was used when trying to close initrd files in the error
path, which caused the machine to hang because a garbage pointer was
dereferenced.

Ideally I'd like to squeeze at least the last two patches in before
v3.3 is released.

Matt Fleming (3):
  x86, efi: Only close open files in error path
  x86, efi; Add EFI boot stub console support
  x86, efi: Add EFI boot stub documentation
