Nathan Whitehorn	97f7cde42c	Remove some dead code: unnecessary isyncs and memory sorting, which are ... handled in mtmsr() and mem_regions(), respectively.	2011-06-02 14:15:44 +00:00
Nathan Whitehorn	52a190480f	Only keep track of PTE validity statistics for pages not locked in the ... table. The 'locked' attribute is used to circumvent the regular page table locking for some special pages, with the result that including locked pages here causes races when updating the stats.	2010-12-28 17:02:15 +00:00
Nathan Whitehorn	41f15bbbd9	Add some isync()s related to the 64-bit MMU scratch page to avoid race ... conditions on its invalidation.	2010-12-11 20:29:52 +00:00
Nathan Whitehorn	bef5da7f98	Add an abstraction layer to the 64-bit AIM MMU's page table manipulation ... logic to support modifying the page table through a hypervisor. This uses KOBJ inheritance to provide subclasses of the base 64-bit AIM MMU class with additional methods for page table manipulation. Many thanks to Peter Grehan for suggesting this design and implementing the MMU KOBJ inheritance mechanism.	2010-12-04 02:42:52 +00:00
