Subject[PATCH] kvm: provide kvm.h for all architecture: fixes headers_install
Date
Ok, here goes the second version.
Andrew, if there are no further complaints, please replace the old patch,
with this version. Thank you.

[PATCH v2] kvm: provide kvm.h for all architecture: fixes headers_install

Currently include/linux/kvm.h is not considered by make headers_install,
because Kbuild cannot handle " unifdef-$(CONFIG_FOO) += foo.h.
This problem was introduced by 040922c04cf2c8ac70be2e88a8a9614ecdb41d2e,
which makes this an 2.6.25 regression.

One way of solving the issue is to enhance Kbuild, but Avi Kivity and David
Woodhouse conviced me, that changing headers_install is not the way to go.
This patch changes the definition for linux/kvm.h to unifdef-y.

If  unifdef-y is used for linux/kvm.h "make headers_check" will fail on all
architectures without asm/kvm.h. Therefore, this patch also provides
asm/kvm.h on all architectures.

Changes since v1:
o use asm-generic/Kbuild.asm (Arnd Bergmann)
o fix comment in asm-frv (David Howells)
