I'm running this patch set since October on amd64 armhf arm64, no
explosions -- besides the obvious when it's not applied yet I forget to
reconfigure initramfs-tools.  Which is getting tedious, so let's merge this
already. :)

I've tested initrd on all of these archs; here's a debug patch to check if
you're actually using it.

As for compressing the kernel itself: the second patch works as submitted
(ie, x86 only).  Porting it to other architectures is straightforward, but
eg. on arm, most boards use u-boot which insists on decompressing the kernel
by itself instead of passing control.  EFI/grub should work, but I haven't
tested that yet.
