[Qemu-devel] [PATCH 3/3] PPC: Round VGA BIOS size to page boundary |
Date: |

When giving KVM a slot of a size not on page boundary, it chokes. So let's
just round up the VGA BIOS size so nobody complains anymore and we don't need
to implement sub-page slots.
Required for booting a PPC guest in KVM.
