It looks like commit 71ae8aac3e19 ("lib: introduce arch optimized hash library") added the asm/hash.h include, and then commit e3fec2f74f7f ("lib: Add missing arch generic-y entries for asm-generic/hash.h") added the asm-generic plumbing for arches that don't have that file in asm/. However, perf doesn't seem to be picking this up for some reason. Does anyone have any ideas as to what could be going wrong here? josh -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
