[Qemu-devel] [PATCH] kvm-all: PAGE_SIZE should be real host page size

[Andrew Jones <drjones@redhat.com>]

Just noticed this while grepping TARGET_PAGE_SIZE for an unrelated
reason. I didn't use qemu_real_host_page_size as kvm_set_phys_mem()
does, because we'd need to make sure page_size_init() has run first.
