From f32269a0d09113b12b68f08dbc5361195176e2dc Mon Sep 17 00:00:00 2001 From: Carsten Otte Date: Tue, 27 Dec 2011 11:27:11 +0100 Subject: [S390] disable MACHINE_IS_VM check for pfault This patch disables the check for MACHINE_IS_VM when initializing the pfault infrastructure. The code checks for successful completion of diag 258 anyway, thus it's safe to try initialization on LPAR anyway. This is needed to use pfault on kvm Signed-off-by: Carsten Otte Signed-off-by: Martin Schwidefsky --- arch/s390/mm/fault.c | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) (limited to 'arch/s390/mm/fault.c') diff --git a/arch/s390/mm/fault.c b/arch/s390/mm/fault.c index a9a301866b3c..a9d3583922ec 100644 --- a/arch/s390/mm/fault.c +++ b/arch/s390/mm/fault.c @@ -509,7 +509,7 @@ int pfault_init(void) .reserved = __PF_RES_FIELD }; int rc; - if (!MACHINE_IS_VM || pfault_disable) + if (pfault_disable) return -1; asm volatile( " diag %1,%0,0x258\n" @@ -530,7 +530,7 @@ void pfault_fini(void) .refversn = 2, }; - if (!MACHINE_IS_VM || pfault_disable) + if (pfault_disable) return; asm volatile( " diag %0,0,0x258\n" @@ -643,8 +643,6 @@ static int __init pfault_irq_init(void) { int rc; - if (!MACHINE_IS_VM) - return 0; rc = register_external_interrupt(0x2603, pfault_interrupt); if (rc) goto out_extint; -- cgit v1.2.3
