fix issue with WE+ bit becoming unset, fix pagefault:not-mapped-in logic

• Fri, 04 Mar 2011 01:36:30 +0000
• by Philip Pemberton <philpem@philpem.me.uk> [Fri, 04 Mar 2011 01:36:30 +0000] rev 104
• fix issue with WE+ bit becoming unset, fix pagefault:not-mapped-in logic
  
  - The WE+ (page write enable) bit was becoming unset when the Page Status bits were being set.
  A stupid mistake in an AND expression was unsetting the write-enable, thus making S4TEST 12,2 and 12,3 fail spectacularly.
  
  - Pagefaults were not being generated correctly for pages which were not mapped in. Even Supervisor code accessing unmapped pages should get a PF.
