I need to revert:
"x86/mm/pat: Fix effective RW computation in lookup_address_in_pgd_attr()"
otherwise I get:
[ 0.108037] ------------[ cut here ]------------ [ 0.108037] CPA detected W^X
Could you send your .config and the full dmesg around the W^X warning, and let us know whether current mainline shows the same warning? The patch stays queued for now.
