source: vbox/trunk/src/VBox/VMM/testcase/tstSSM.cpp@ 94018

Last change on this file since 94018 was 93554, checked in by vboxsync, 3 years ago

VMM: Changed PAGE_SIZE -> GUEST_PAGE_SIZE / HOST_PAGE_SIZE, PAGE_SHIFT -> GUEST_PAGE_SHIFT / HOST_PAGE_SHIFT, and PAGE_OFFSET_MASK -> GUEST_PAGE_OFFSET_MASK / HOST_PAGE_OFFSET_MASK. Also removed most usage of ASMMemIsZeroPage and ASMMemZeroPage since the host and guest page size doesn't need to be the same any more. Some work left to do in the page pool code. bugref:9898
