x86/UV: Check for alloc_cpumask_var() failures properly in uv_nmi_setup()
GCC warned about:
arch/x86/platform/uv/uv_nmi.c: In function ‘uv_nmi_setup’:
arch/x86/platform/uv/uv_nmi.c:664:2: warning: the address of ‘uv_nmi_cpu_mask’ will always evaluate as ‘true’
The reason is this code:
alloc_cpumask_var(&uv_nmi_cpu_mask, GFP_KERNEL);
BUG_ON(!uv_nmi_cpu_mask);
which is not the way to check for alloc_cpumask_var() failures - its
return code should be checked instead.
