Better fix for quitting X hang. Interrupted mailbox reads are not something we can reliably recover from, so down_interruptable is not a safe call.

commit 052b1987 upstream. When swapon() was not passed the SWAP_FLAG_DISCARD option, sys_swapon() will still perform a discard operation. This can cause problems if discard is slow or buggy. Reverse the order of the check so that a discard operation is performed only if the sys_swapon() caller is attempting to enable discard.

resulting in overrun of the input buffer and memory corruption causing an OOPS. We should be checking for the fact that we might get more data than we want. Thanks Naren.

Commit d64b84ca by accident reduced the maximum overall DMA sync timeout. The maximum overall timeout was reduced from 100ms to 30ms, which isn't enough for many cards. Increase it to 150ms, just to be extra safe. According to commit 872a8ff7 in the MMC subsystem, some cards require crazy long timeouts (3s), but as we're busy-waiting, and shouldn't delay for such a long time, let's hope 150ms will be enough for most cards.

80 MHz clock isnt't suited well to be dividable to get SD clocks of 25 MHz (default mode) or 50 MHz (high speed mode). 50 MHz are perfect to drive the SD interface at ideal frequencies.

Add a parameter to disable high-speed mode for the few cards that still might have problems. High-speed mode is enabled by default.

Some additional quirks are needed for correct operation. There's no SDHCI capabilities register documented, and it always reads zero, so add SDHCI_QUIRK_MISSING_CAPS. Apparently SDHCI_QUIRK_NO_HISPD_BIT is needed for many cards to work correctly in high-speed mode, so add it as well.

The custom clock handling code is redundant and buggy. The MMC/SDHCI subsystem does a better job than it, so remove it for good.

Experiments show that it doesn't really take that long to sync, so we can reduce the poll interval slightly. Might improve performance a bit.

Adds a quirk that sets the data read timeout to a fixed value instead of relying on the information in the CSD. The timeout value chosen is 300ms since that has proven enough for the problematic cards found, but could be increased if other cards require this. This patch also enables this quirk for certain Micron cards known to have this problem.
