Hi Linus,
Could you pull this branch please?
There are three main parts:
(1) I found I needed some more fixups in the wake of testing Arm64 (some
asm/unistd.h files had weird guards that caused problems - mostly in
arches for which I don't have a compiler) and some __KERNEL__ splitting
needed to take place in Arm64.
(2) I found that c6x was missing some __KERNEL__ guards in its asm/signal.h.
Mark Salter pointed me at a tree with a patch to remove that file
entirely and use the asm-generic variant instead.
(3) Lastly, m68k turned out to have a header installation problem due to it
lacking a kvm_para.h file.
The conditional installation bits for linux/kvm_para.h, linux/kvm.h and
linux/a.out.h weren't very well specified - and didn't work if an arch
didn't have the asm/ version of that file, but there *was* an
asm-generic/ version.
It seems the "ifneq $((wildcard ...),)" for each of those three headers
in include/kernel/Kbuild is invoked twice during header installation, and
the second time it matches on the just installed asm-generic/kvm_para.h
file and thus incorrectly installs linux/kvm_para.h as well.
Most arches actually have an asm/kvm_para.h, so this wasn't detectable in
those.
