Subject: paravirt: unstatic leave_mm
X-Git-Tag: v3.12-rc1~28092^2~34
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=53787013248f52af81d99f63454e5a5cf34d6f12;p=kernel%2Fkernel-generic.git

paravirt: unstatic leave_mm

Make globally leave_mm visible, specifically so that Xen can use it to
shoot-down lazy uses of cr3.
