Subject: [PATCH] x86/paravirt: return full 64-bit result
Date: Tue, 03 Feb 2009 16:00:38 -0800 [thread overview]
Message-ID: <4988DAA6.7000102@goop.org> (raw)
A hunk went missing in the original patch, and callee-save callsites were
not marked as returning the upper 32-bit of result, causing Badness.
