Date: Thu, 21 May 2015 13:57:04 +0530 From: "Gautham R. Shenoy" <ego@...ux.vnet.ibm.com> To: Paul Mackerras <paulus@...ba.org>, Benjamin Herrenschmidt <benh@...nel.crashing.org>, Michael Ellerman <mpe@...erman.id.au> Cc: linux-kernel@...r.kernel.org, kvm-ppc@...r.kernel.org, linuxppc-dev@...ts.ozlabs.org, "Aneesh Kumar K.V" <aneesh.kumar@...ux.vnet.ibm.com>, "Gautham R. Shenoy" <ego@...ux.vnet.ibm.com> Subject: [PATCH] book3s_hv_rmhandlers:Pass the correct trap argument to kvmhv_commence_exit In guest_exit_cont we call kvmhv_commence_exit which expects the trap number as the argument. However r3 doesn't contain the trap number at this point and as a result we would be calling the function with a spurious trap number. Fix this by copying r12 into r3 before calling kvmhv_commence_exit as r12 contains the trap number Signed-off-by: Gautham R.
