Subject: devm_memremap_pages: use numa_mem_id
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=7eff93b7c99f5d0024aee677c6c92e32af22e1d2;p=openwrt%2Fstaging%2Fblogic.git

devm_memremap_pages: use numa_mem_id

Hint to closest numa node for the placement of newly allocated pages.
As that is where the device's other allocations will originate by
default when it does not specify a NUMA node.
