From e680080e653b8c8725ca620bf22a5f8480f40cb5 Mon Sep 17 00:00:00 2001 From: Gleb Natapov Date: Wed, 28 Apr 2010 19:15:33 +0300 Subject: KVM: x86 emulator: fix X86EMUL_RETRY_INSTR and X86EMUL_CMPXCHG_FAILED values Currently X86EMUL_PROPAGATE_FAULT, X86EMUL_RETRY_INSTR and X86EMUL_CMPXCHG_FAILED have the same value so caller cannot distinguish why function such as emulator_cmpxchg_emulated() (which can return both X86EMUL_PROPAGATE_FAULT and X86EMUL_CMPXCHG_FAILED) failed.
