Could you run this just before cutting 4.10-rc1?

PATT='^[[:blank:]]*#[[:blank:]]*include[[:blank:]]*<asm/uaccess.h>'
sed -i -e "s!$PATT!#include <linux/uaccess.h>!" \
	`git grep -l "$PATT"|grep -v ^include/linux/uaccess.h`

Doing that against 4.9 would only cause a bunch of pointless trivial
conflicts during the merge window and would probably need to be run
again to pick the newly added includes of asm/uaccess.h after the end
of the window anyway.  It's 100% mechanical search-and-replace - the only
remaining include of asm/uaccess.h should be in linux/uaccess.h and
everything else should switch to asm/uaccess.h.  There used to be several
places where linux/uaccess.h would cause trouble (the worst was probably
asm/processor.h on x86), but all of those had been taken out and shot during
the last window and AFAICS nothing new of that sort has appeared in anything
merged into -next.
