Last change on this file since 103980 was 103980, checked in by vboxsync, 11 months ago

ValKit/bs3kit,bs3-cpu-instr-3: Don't set g_uBs3TrapEipHint automatically in Bs3TrapSetJmpAndRestoreWithExtCtx as we don't know the actual trap/exit EIP and it may have a different value in the top word from pCtxRestore->rip. Instead the caller has to set it like with Bs3RegCtxRestore. bugref:9898
