Hi all, Today's linux-next merge of the s390 tree got a conflict in: arch/s390/kernel/smp.c between commit: 8ebf6da9db1b ("s390/ftrace: fix potential crashes when switching tracers") from Linus' tree and commit: 11886c199d8d ("s390: add machine check SIGP") from the s390 tree. I fixed it up (see below) and can carry the fix as necessary. This is now fixed as far as linux-next is concerned, but any non trivial conflicts should be mentioned to your upstream maintainer when your tree is submitted for merging. You may also want to consider cooperating with the maintainer of the conflicting tree to minimise any particularly complex conflicts. -- Cheers, Stephen Rothwell diff --cc arch/s390/kernel/smp.c index 10dbb12eb14d,fc1041257c60..000000000000 --- a/arch/s390/kernel/smp.c +++ b/arch/s390/kernel/smp.c @@@ -403,7 -404,12 +404,12 @@@ int smp_find_processor_id(u16 address return -1; } + void schedule_mcck_handler(void) + { + pcpu_ec_call(pcpu_devices + smp_processor_id(), ec_mcck_pending); + } + -bool arch_vcpu_is_preempted(int cpu) +bool notrace arch_vcpu_is_preempted(int cpu) { if (test_cpu_flag_of(CIF_ENABLED_WAIT, cpu)) return false;
