Subject: [PATCH 1/3] qemu: fix page_check_range

Fixes a segfault. In a case, where signals are delivered
back to back. The second signal causes a segfalt, because
the frame cannot be written to (it was protected beause
the restorer executed from it), but the unprotect
logic exited too early if the checked range exceeded
1 page.
