Subject: m32r, mm: set all online nodes in N_NORMAL_MEMORY
X-Git-Tag: v3.0-rc1~247
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0091a47da0b720ca39511c7d90dcc768cafcaf58;p=platform%2Fkernel%2Flinux-exynos.git

m32r, mm: set all online nodes in N_NORMAL_MEMORY

For m32r, N_NORMAL_MEMORY represents all nodes that have present memory
since it does not support HIGHMEM.  This patch sets the bit at the time
the node is initialized.

If N_NORMAL_MEMORY is not accurate, slub may encounter errors since it
uses this nodemask to setup per-cache kmem_cache_node data structures.
