Subject[PATCH v5 0/4] Certificate insertion support for x86 bzImages
These patches add support for modifying the reserved space for extra
certificates in a compressed bzImage in x86. This allows separating the
system keyring certificate from the kernel build process. After the kernel
image is distributed, the insert-sys-cert script can be used to insert the
certificate for x86.


* Added CRC fixing (3/4)

* Applied 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)
