New Revision: 290656
URL: https://svnweb.freebsd.org/changeset/base/290656
Log:
Fix cp15 PAR definition and function. While here, add cp15 ATS1CPW
function which checks an address for privileged (PL1) write access.
The function is inlined so it does not bring any cost, but makes
function set for checking privileged access complete.
