Later patchsets will gradually build out the functionality. The most critical issue that came up awhile back was how to configure the size of the percpu area. Here we simply use a kernel parameter and use the static size of the existing percpu allocator for modules as a default. The effect of this patchset is to make the size of percpu data for modules configurable. Its no longer fixed at 8000 bytes. Changes: V5->V6: - Fix various issues in the per cpu alloc - Make percpu reserve not depend on CONFIG_MODULES. V4->V5: - Fix various things pointed out by Pekka. - Remove page alignment check from module.c and put it into cpu_alloc.c V3->V4: - Gut patches to the bare essentials: Only replace modules.c percpu alloocator - Make percpu reserve area configurable via a kernel parameter -- -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
