#1732122 — microblaze fails to to compile with allmodconfig

Hi,
I've started seeing the following compilation failures with microblaze
with the current linux-next (next-20170913). I have no idea when this
has been introduced but microblaze clearly doesn't have arch specific
kvm_para.h.

In file included from ./include/linux/kvm_para.h:4:0,
                 from kernel/watchdog.c:29:
./include/uapi/linux/kvm_para.h:32:26: fatal error: asm/kvm_para.h: No such file or directory
 #include <asm/kvm_para.h>
                          ^
compilation terminated.
make[1]: *** [kernel/watchdog.o] Error 1
make[1]: *** Waiting for unfinished jobs....

allyesconfig and allnoconfig compile just fine. Maybe allmodconfig needs
an update?

arch/microblaze/include/uapi/asm/Kbuild needs a line

    generic-y += kvm_para.h

?

Thanks for reporting this.

tile/arm/alpha/frv/nm10300/hexagon/sparc/score have
#include <asm-generic/kvm_para.h>

ppc and x86 contain implementation.

s390 and mips are just empty files

Issue was likely introduced by:
"uapi: export all headers under uapi directories"
(commit fcc8487d477a3452a1d0ccbdd4c5e0e1e3cb8bed)

Where header-y += kvm_para.h was removed.

Masahiro/Nicolas: Any issue with this proposed fix?

Thanks,
Michal

Yes.

I think it is the right thing to do.

No.
Nicolas's commit is innocent.



I think the bad commit is this:


commit 83f0124ad81e87b74c2f461b1794e57ab5e7fea0
Author: Tobias Klauser <tklauser@distanz.ch>
Date:   Fri May 19 13:45:16 2017 +0200

    microblaze: remove asm-generic wrapper headers

    Some of microblaze's asm and uapi header are merely including their
    asm-generic counterpart. Thus, the arch specific headers can be removed
    and the asm-generic header can be used directly via generic-y.

    The headers removed from uapi don't need to be added to generic-y in the
    uapi Kbuild in order to get exported, as they are already listed in
    mandatory-y.

    Also order the generic-y list alphabetically.

It removed
arch/microblaze/include/uapi/asm/kvm_para.h
but, missed to add  "generic-y += kvm_para.h"
