Re: [PATCH 0/7] x86/UV/KDB/NMI: Updates for NMI/KDB handler for SGIUV

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
