Subject: KVM: PPC: Rename deliver_interrupts to prepare_to_enter
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=7e28e60ef974d0eeb43112ef264d8c130f7b7bf4;p=openwrt%2Fstaging%2Fblogic.git

KVM: PPC: Rename deliver_interrupts to prepare_to_enter

This function also updates paravirt int_pending, so rename it
to be more obvious that this is a collection of checks run prior
to (re)entering a guest.
