Kalle Valo says:

====================
wireless-drivers fixes for 4.10

Only two fixes at this time. The rtlwifi fix is an important one as it
fixes a reported oops and Linus was already asking about it. The
orinoco fix is not tested on a real device, because it's old legacy
hardware and hardly no-one use it, but it should fix a (theoretical)
issue with VMAP_STACK.
