This change modifes the PE .text section to start after the first sector of the kernel image. The header may be modified by the UEFI secure boot signing, so it is not appropriate for it to be included in one of the image sections. Since the sections are part of the secure boot hash, this modification to the .text section contents would invalidate the secure boot signed hash. Note: UEFI secure boot does hash the image header, but fields that are changed by the signing process are excluded from the hash calculation. This exclusion process is only handled for the image header, and not image sections. Luckily, we can still easily boot without the first sector by initializing a few fields in arch/x86/boot/compressed/eboot.c.
