Ard Biesheuvel c1badd7b65 arm64: mm: fix thinko in non-global page table attribute check ... commit 753e8abc36 upstream. The routine pgattr_change_is_safe() was extended in commit 4e60205655 ("arm64: mm: Permit transitioning from Global to Non-Global without BBM") to permit changing the nG attribute from not set to set, but did so in a way that inadvertently disallows such changes if other permitted attribute changes take place at the same time. So update the code to take this into account. Fixes: 4e60205655 ("arm64: mm: Permit transitioning from Global to ...")
