I brought this up a few years ago, and had it shot down, because of a
few poorly substantiated claims of zImage-only machines; those claims
really need to be debugged since they might indicate A20-related failures.
Anyway...
Can we please kill zImage? In addition to be completely useless for
modern kernels, it causes unnecessary complexity in boot loaders.

These beasts are still alive and kicking. I boot a handful of
arm and ppc boards on a frequent basis that are zImage
only. The kicker is I don't have the bootloader source for
most of them, so changing to a different image format is
tough at best.
Not a vote one way or the other, just some observations
from my day to day.

Sorry, the zImage/bzImage distinction is x86 only. Some other
architectures call their output zImage, but it's a different format
entirely.
So I was referring specifically to x86.

Ah my mistake, I quickly scanned and didn't pick
up the x86 reference. Nothing to see here :)

I hope so.
BTW: I'd just kill old zImage and make it identical to bzImage
(I mean "make zImage" would now produce arch/i386/zImage identical
to arch/i386/bzImage made by "make bzImage").
Then we could use zImage as for other platforms.
