Hm, do you test-build your patches? This series produces the following
annoying warning:
arch/x86/platform/uv/uv_nmi.c: In function âuv_nmi_setupâ:
arch/x86/platform/uv/uv_nmi.c:664:2: warning: the address of âuv_nmi_cpu_maskâ will always evaluate as âtrueâ [-Waddress]
This:
alloc_cpumask_var(&uv_nmi_cpu_mask, GFP_KERNEL);
BUG_ON(!uv_nmi_cpu_mask);
the way to check for allocation failures is by checking the return value
of alloc_cpumask_var():
BUG_ON(!alloc_cpumask_var(&uv_nmi_cpu_mask, GFP_KERNEL));
I've fixed this in the patch.
Thanks,
Ingo
