The patch titled Subject: lib/bitmap.c: guard exotic bitmap functions by CONFIG_NUMA has been removed from the -mm tree. Its filename was lib-bitmapc-guard-exotic-bitmap-functions-by-config_numa.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Rasmus Villemoes <linux@xxxxxxxxxxxxxxxxxx> Subject: lib/bitmap.c: guard exotic bitmap functions by CONFIG_NUMA The bitmap_remap, _bitremap, _onto and _fold functions are only used, via their node_ wrappers, in mm/mempolicy.c, which is only built for CONFIG_NUMA. The helper bitmap_ord_to_pos used by these functions is global, but its only external caller is node_random() in lib/nodemask.c, which is also guarded by CONFIG_NUMA.
