Subject: KVM: PPC: Book3S: ifdef on CONFIG_KVM_BOOK3S_32_HANDLER for 32bit
X-Git-Tag: v4.14-rc1~7478^2~2^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ab78475c76bd8c54375d8a778200c59314973d30;p=platform%2Fkernel%2Flinux-rpi.git

KVM: PPC: Book3S: ifdef on CONFIG_KVM_BOOK3S_32_HANDLER for 32bit

The book3s_32 target can get built as module which means we don't see the
config define for it in code. Instead, check on the bool define
CONFIG_KVM_BOOK3S_32_HANDLER whenever we want to know whether we're building
for a book3s_32 host.

This fixes running book3s_32 kvm as a module for me.
