The following patch series is targetted at two things - fixing the SDIO
interrupt handling, and fixing problems with the sdhci driver.
- the first two patches from Thomas Gleixner provide genirq support to
allow us to fix the SDIO interrupt handling in a graceful manner.
- patch 3 adds support for avoiding the buggy sdio_irq thread - the
problem is described in that commit. Other solutions were explored,
but this is the one which was settled on after discussions between
Thomas, scheduler people and myself.
- patches 4 to 7 update sdhci to use a genirq to deal with the threaded
part of the interrupts.
- patch 8 allows card interrupts to be received from a SDIO card while
runtime suspended. Without this patch, Wifi cards attached to a
kernel with runtime PM support built in totally fail to work. This
allows them to work. Tested in 4-bit mode.
- patches 9 onwards are cleanups and fixes to the sdhci code.

FTTC broadband for 0.8mile line: 5.8Mbps down 500kbps up. Estimation
in database were 13.1 to 19Mbit for a good line, about 7.5+ for a bad.
Estimate before purchase was "up to 13.2Mbit".

Rather than having platform_reset_enter/platform_reset_exit methods,
turn the core of the reset handling into a library function which
platforms can call at the appropriate moment in their (new) reset
method.

Add sdhci_set_uhs_signaling() and always call the set_uhs_signaling
method. This avoids quirks being added into sdhci_set_uhs_signaling().
