[PATCH 2/2] KVM: arm64: Depend on HAVE_KVM => OF instead of directly on OF

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Select HAVE_KVM if the KVM dependency is met (OF / Open Firmware), and
make KVM depend on HAVE_KVM instead of directly on OF.  This fixes the
oddity where arm64 configs can end up with KVM=y and HAVE_KVM=n, and will
hopefully prevent breakage if there are future users of HAVE_KVM.

Note, arm64 unconditionally selects OF, and has always done so (see
commit 8c2c3df31e3b ("arm64: Build infrastructure").  Keep the somewhat
pointless HAVE_KVM dependency on OF to document that KVM requires Open
Firmware support.

No functional change intended.
