New Revision: 248825
URL: http://svnweb.freebsd.org/changeset/base/248825
Log:
Except one case mps(4) driver does not touch the data and works well with
unmapped I/O. That one exception is access to INQUIRY VPD request result.
Those requests are never unmapped now, but to be safe add respective check
there and allow unmapped I/O for the SIM by setting PIM_UNMAPPED flag.
