[PATCH 1/4] i386/x86_64: make linux header definitions arch-specific |
|
Date: |
Tue, 5 Sep 2017 21:41:11 +0100 |
Rename GRUB_LINUX_MAGIC_SIGNATURE -> GRUB_LINUX_I386_MAGIC_SIGNATURE
and linux_kernel_header -> linux_i386_kernel_header.
Also change the include guard on grub/i386/linux.h to prevent clashes
when including multiple linux.h headers (like in commands/file.c).

OK, so one question here: in order to follow existing style, I have kept
to the existing linux_ format. Is that the appropriate prefix, or should
this be grub_linux_ like I originally used in the ARM series?
Regardless, I intend to align the ARM patches to whatever format ends up
being used for this patch.
