Replace smp_call_function_single_async with smp_call_csd and modify all the invocations.
Signed-off-by: Donghai Qiao <dqiao@redhat.com> --- v1 -> v2: Removed 'x' from the function names and change XCALL to SMP_CALL from the new macros v2 -> v3: Modifed all the invocations of smp_call_function_single_async() to smp_call_csd() arch/mips/kernel/process.c | 2 +- arch/mips/kernel/smp.c | 2 +- arch/s390/pci/pci_irq.c | 2 +- arch/x86/kernel/cpuid.c | 2 +- arch/x86/lib/msr-smp.c | 2 +- block/blk-mq.c | 2 +- drivers/clocksource/ingenic-timer.c | 2 +- drivers/cpuidle/coupled.c | 2 +- drivers/net/ethernet/cavium/liquidio/lio_core.c | 2 +- include/linux/smp.h | 3 --- kernel/debug/debug_core.c | 2 +- kernel/sched/core.c | 2 +- kernel/sched/fair.c | 2 +- net/core/dev.c | 2 +- 14 files changed, 13 insertions(+), 16 deletions(-)
