For multi-node Loongson-3 (NUMA configuration), r4k_blast_scache() can only flush Node-0's scache. So we add r4k_blast_scache_node() by using (CAC_BASE | (node_id << NODE_ADDRSPACE_SHIFT)) instead of CKSEG0 as the start address. Signed-off-by: Huacai Chen <chenhc@lemote.com> [paul.burton@mips.com: Include asm/mmzone.h from asm/r4kcache.h for nid_to_addrbase(). Add asm/mach-generic/mmzone.h to allow inclusion for all platforms.] Signed-off-by: Paul Burton <paul.burton@mips.com> Patchwork: https://patchwork.linux-mips.org/patch/21129/ Cc: Ralf Baechle <ralf@linux-mips.org> Cc: James Hogan <james.hogan@mips.com> Cc: Steven J .
