H A Ddevice_pager.cdiff e9d37c9f8d5dd0072a00e3c7db33b0cc36c93ca4 Sun May 01 19:48:43 CEST 2016 Konstantin Belousov <kib@FreeBSD.org> Avoid duplicated calls to pmap_page_get_memattr().

Avoid logging inconsistency for the /dev/mem device at all. The driver
leaves memattr intact, and the corrective action in the device pager
handles it right.

In the logged warning, name the driver we blame, and show memory
attributes values.
