Will Newton 50cec37c1a mmc: Improve MMC_TEST config text.
The test file is created under debugfs, not sysfs. Also remove
the unnecessary default n.

Olof Johansson 5e71b7a64c mmc: make number of mmcblk minors configurable
The old limit of number of minor numbers per mmcblk device was hardcoded
at 8.  This isn't enough for some of the more elaborate partitioning
schemes, for example those used by Chrome OS.

Since there might be a bunch of systems out there with static /dev
contents that relies on the old numbering scheme, let's make it a
build-time option with the default set to the previous 8.

Also provide a boot/modprobe-time parameter to override the config
default: mmcblk.perdev_minors.

This currently only accepts the GPS class since that's all I have for
testing.  Tested with a Matsushita GPS and gpsd version 2.34.

Pierre Ossman 98ccf14909 mmc: bounce requests for simple hosts
Some hosts cannot do scatter/gather in hardware. Since not doing sg
is such a big performance hit, we (optionally) bounce the requests
to a simple linear buffer that we hand over to the driver.
