From aa6b54461cc5c0019b9d792adf3176b444c10763 Mon Sep 17 00:00:00 2001 From: Mike Travis Date: Mon, 31 Mar 2008 08:41:55 -0700 Subject: asm-generic: add node_to_cpumask_ptr macro Create a simple macro to always return a pointer to the node_to_cpumask(node) value. This relies on compiler optimization to remove the extra indirection: #define node_to_cpumask_ptr(v, node) \ cpumask_t _##v = node_to_cpumask(node), *v = &_##v For those systems with a large cpumask size, then a true pointer to the array element can be used: #define node_to_cpumask_ptr(v, node) \ cpumask_t *v = &(node_to_cpumask_map[node]) A node_to_cpumask_ptr_next() macro is provided to access another node_to_cpumask value. The other change is to always include asm-generic/topology.h moving the ifdef CONFIG_NUMA to this same file. Note: there are no references to either of these new macros in this patch, only the definition.
