[Qemu-devel] [PULL 6/7] kvm: initialize qemu_host_page_size |

StGit/0.17-dirty |
From: Alexey Kardashevskiy <address@hidden>
There is a HOST_PAGE_ALIGN macro which makes sense for KVM accelerator
but it uses qemu_host_page_size/qemu_host_page_mask which initialized
for TCG only.
This moves qemu_host_page_size/qemu_host_page_mask initialization from
TCG's page_init() and adds a call for it from kvm_init().
