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-71b6-9c3a97d68927 at infradead.org
"lib/test_firmware: add header file to prevent build errors"

other-patch-2:
lkml.kernel.org/r/b3b7eebb-0e9f-f175-94a8-379c5ddcaa86 at 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,
