So, if I apply this on top of next-20180116 I do get a BUG from
bio_split() on line 1833 in block/bio.c. However, that BUG also exists
without these patches.

More importantly, read-only detection with this applied still works on
for example Jetson TK1:

[ 28.547261] mmc1: new high speed SDHC card at address 59b4
[ 28.558814] mmcblk1: mmc1:59b4 SDC 14.7 GiB (ro)

So:

Tested-by: Thierry Reding <treding@nvidia.com>

and:

Acked-by: Thierry Reding <treding@nvidia.com>
