[PATCH] x86: little fix in 'include/asm-x86/topology.h'
|
|
Before 'topology_32.h' and 'topology_64.h' were unified, topology defines in a
X86_64 kernel were declared if CONFIG_SMP was enabled.
Now, post unification, these same defines in a X86_64 kernel are only being
declared if CONFIG_NUMA and CONFIG_SMP are enabled.
This, for example, breaks 'perfmon_amd64.c' compilation.
This patch defines ENABLE_TOPO_DEFINE if this is a X86_64 kernel and we
have SMP support enabled.
