CVS commit: src/sys/arch/xen/xen

[Jean-Yves Migeon <jym%netbsd.org@localhost>]

Module Name:    src
Committed By:   jym
Date:           Wed Mar  4 10:32:36 UTC 2009

Modified Files:
        src/sys/arch/xen/xen: privcmd.c

Log Message:
Do not continue silently on a page fault for an INVALID_PAGE, and instead
report an EFAULT like Xen does.

This avoids bad situations where a domain calls privpgop_fault() in a loop
by trying to map an invalid MFN.
