6773712672 if: fix bio_get stack corruption when bio is on stack 
I am unsure whether this might break compatibility to some
very ancient kernels.

AFAICR, it could have been needed long ago, when some old 32bit
kernels needed kmap().

Anyway, I don't have those old kernels anymore.

0d579d48ba net: fix O_NONBLOCK races 
Runtime modification of _shared_ socket flags like O_NONBLOCK
is a bad idea. If I remember correctly, long ago there was no
other way. Current kernels allow different flags on the stack per
kernel_*() call, but I am not sure whether this could break
compatibility with some very ancient kernels. Unfortunately, I
cannot test MARS with these dinosaur kernels anymore, but hopefully
nobody uses them anyway.
