KVM: rename is_writeble_pte() to is_writable_pte()
There are two spellings of "writable" in arch/x86/kvm/mmu.c and paging_tmpl.h . This patch renames is_writeble_pte() to is_writable_pte() and makes grepping easy. New name is consistent with the definition of itself: return pte & PT_WRITABLE_MASK; Signed-off-by: Takuya Yoshikawa <yoshikawa.takuya@oss.ntt.co.jp> Signed-off-by: Avi Kivity <avi@redhat.com>
