Hello Ian, We had bug in usage of pmap_remap_vm_attr() and fixing it didn't help for the issue so the second bug has been found here. > Should we consider merging this to 11-stable? As far as I know nobody besides Armada38x is using this function in HEAD and nobody uses it in 11. You may merge it to 11 though (just for the safety of this code in the future). > > -- Ian _______________________________________________ svn-src-head@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
