Author: marcel Date: Mon Jul 2 21:21:12 2012 New Revision: 238033 URL: http://svn.freebsd.org/changeset/base/238033
Log: Fix a typo that resulted in or-ing PTE_UW twice whrn PTE_SW was needed. Note that setting the PTE_MODIFIED bit based on whether write is possible is incorrect. We should set PTE_MODIFIED based on whether the access is a write operation.
