ssm.h@ 55000

Last change on this file since 55000 was 50575, checked in by vboxsync, 11 years ago
VMM: Added SSMR3RegisterStub and used it to provide saved state load-exec stubs for ignoring CSAM and PATM state when VBOX_WITH_RAW_MODE isn't defined or when HM is active.
Property svn:eol-style set to `native` Property svn:keywords set to `Author Date Id Revision`
