[PATCH v5 0/4] Certificate insertion support for x86 bzImages

> These patches add support for modifying the reserved space for extra

I know it's been a while since these patches were posted and they seem to
fail between the cracks ...
Is there anything that prevents merging them?
> * Added CRC fixing (3/4)
> * Applied checkpatch.pl suggestions (2/4, 3/4)
> * Cleaned up the commit messages (1/4, 2/4)
> * Added the build file to .gitignore (1/4)
> * Rewrote 1/4 to insert incompressible bytes are at build time. Previous
> solution required changes to <arch>/boot/Makefile's for modifying the
> vmlinux file after linking, and did not work well with cross compilation.
> * Added 2/4 for ELF class-independent processing of vmlinux file, in case
> the script was compiled for 64-bit and the kernel was compiled for 32-bit.
> * Reordered 3/4, added x86 bzImage boot version (>=2.08) verification.
> * Rebased arch/boot/x86/Makefile patch (removed in v3)
