#1445295 — linux-next: build failure after merge of the tip tree

Hi all,

After merging the tip tree, today's linux-next build (x86_64 allnoconfig)
failed like this:

In file included from arch/x86/kernel/x8664_ksyms_64.c:10:0:
arch/x86/include/asm/pgtable.h:38:8: error: unknown type name 'spinlock_t'
 extern spinlock_t pgd_lock;
        ^

Probably caused by commit

  186f43608a5c ("x86/kernel: Audit and remove any unnecessary uses of module.h")

I added this patch for today (maybe adding the include to
arch/x86/include/asm/pgtable.h would be better?):

Wondering why I didn't see this, when I _thought_ I did the same
coverage, I learned an interesting thing.  I'd been doing 

make ARCH=i386 allnoconfig
make allnoconfig

...figuring on x86_64 host that I'd need to explicitly choose i386 and
that w/o an ARCH specified, I'd get the native arch...  Not so.  I just
end up doing the i386 arch coverage twice.  :-(   I'll go out on a limb
here and guess I'm not the only person to fall into that trap.

I'll now be using:

make ARCH=i386 allnoconfig
make ARCH=x86_64 allnoconfig

Thanks Stephen for the fix and for helping find this gap in my tests.
If my build coverage moves to Power like yours, I'll still be good. :)

Paul.
