Subject: [PATCH v2] Correct use of IBRS_ATT name, should be IBRS_ALL
Date: Mon, 5 Feb 2018 11:02:20 +0000	[thread overview]
Message-ID: <20180205110220.ky2ih34egygmg4xs@starbug-vm.ie.oracle.com> (raw)

Fixes a comment in commit 117cc7a908c83697b0b737d15ae1eb5943afe35b
("x86/retpoline: Fill return stack buffer on vmexit")

While the original name was "IBRS All The Time" (IBRS_ATT),
the publicly documented name is IBRS_ALL, we should be using that.
