Andrew, This patch has mostly survived both 0day and ozlabs multi-arch testing with 2 build errors being reported by both of them. I have posted patches for those separately. (and are attached here) other-patch-1: lkml.kernel.org/r/5664ced1-a0cd-7e4e-71b6-9c3a97d68...@infradead.org "lib/test_firmware: add header file to prevent build errors" other-patch-2: lkml.kernel.org/r/b3b7eebb-0e9f-f175-94a8-379c5ddca...@infradead.org "integrity/security: fix digsig.c build error" Will you see that these are merged or do you want me to repost them? thanks, -- ~Randy
