172ae196da38208e5f1e3485715a89f2d53c6880vboxsync; The setjmp variant used for calling Ring-3.
172ae196da38208e5f1e3485715a89f2d53c6880vboxsync; This differs from the normal setjmp in that it will resume VMMR0CallHost if we're
de6e321f351aa489a6a62bed474390a0056e8093vboxsync; in the middle of a ring-3 call. Another differences is the function pointer and
de6e321f351aa489a6a62bed474390a0056e8093vboxsync; argument. This has to do with resuming code and the stack frame of the caller.
