This patch set introduces a new request_atomic() interface for the
MMC host controller, which is used to submit a request to host in
the atomic context, such as in the irq hard handler, to reduce the
request latency.

This patch set is based on mmc/next_host_sq branch:
https://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc.git/log/?h=next_host_sq

Any comments are welcome. Thanks.
