which shows two things:
1- a8f5034540195307362d071a8b387226b410469f should have a x86-64 version
2- the limit looks entirely artificial

So, is removing the limit prone to bite me?

OG.

The build system merely tries to warn you it's not going to fit on a floppy disk. "bzImage" means "Big zImage", not "bz2-compressed Image", so unless you're building a floppy disk, don't use zImage.


You failed to notice the "is_big_kernel ? 0x40000 : ..." part, which
means the 4Mb limit is for bzImage. And the "die(...)" part, which
means it's not a warning but an error.


Sorry, I thought it was you who made that patch.
