Max Filippov 147128e775 xtensa: fix TLB sanity checker ... commit 36de10c478 upstream. Virtual and translated addresses retrieved by the xtensa TLB sanity checker must be consistent, i.e. correspond to the same state of the checked TLB entry. KASAN shadow memory is mapped dynamically using auto-refill TLB entries and thus may change TLB state between the virtual and translated address retrieval, resulting in false TLB insanity report. Move read_xtlb_translation close to read_xtlb_virtual to make sure that read values are consistent.
