From: H. Peter Anvin Date: Wed, 28 Mar 2012 20:11:36 +0000 (-0700) Subject: Merge branch x86/build into x86/efi and fix up arch/x86/boot/tools/build.c X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a9aff3eaaf0966c2a1bb3717d811363d81e52c76;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git Merge branch x86/build into x86/efi and fix up arch/x86/boot/tools/build.c Reason for merge: The updates to the EFI boot stub generation conflicted with the changes to properly use the get/put_unaligned_le*() macros to generate images. This merge commit completes the conversion in arch/x86/boot/tools/build.c including the places in the code which had been changed on the x86/efi branch.
