Subject: RISC-V: Make NUMA depend on SMP
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f01e631cccab4b299cf005c42a3176595a3f3f9d;p=linux.git

RISC-V: Make NUMA depend on SMP

In theory these are orthogonal, but in practice all NUMA systems are
SMP.  NUMA && !SMP doesn't build, everyone else is coupling them, and I
don't really see any value in supporting that configuration.
