mmc,sdio: helper function for transfer padding

There are a lot of crappy controllers out there that cannot handle
all the request sizes that the MMC/SD/SDIO specifications require.
In case the card driver can pad the data to overcome the problems,
this commit adds a helper that calculates how much that padding
should be.

A corresponding helper is also added for SDIO, but it can also deal
with all the complexities of splitting up a large transfer efficiently.

Anton Vorontsov [Tue, 17 Jun 2008 14:17:39 +0000 (18:17 +0400)]
mmc: change .get_ro() callback semantics

Now get_ro() callback must return 0/1 values for its logical states, and
negative errno values in case of error. If particular host instance doesn't
support RO/WP switch, it should return -ENOSYS.

This patch changes some hosts in two ways:

1. Now functions should be smart to not return negative values in
   "RO asserted" case (particularly gpio_ calls could return negative
   values for the outermost GPIOs).

   Also, board code usually passes get_ro() callbacks that directly return
   gpioreg & bit result, so at91_mci, imxmmc, pxamci and mmc_spi's get_ro()
   handlers need take special care when returning platform's values to the
   mmc core.

2. In case of host instance didn't implement get_ro() callback, it should
   really return -ENOSYS and let the mmc core decide what to do about it
   (mmc core thinks the same way as the hosts, so it isn't functional

[S390] sclp_tty: Fix scheduling while atomic bug.

Finally fixes a possible scheduling while in atomic context bug. The driver
used to wait on a waitqueue if no empty buffer was available. This could
lead to a deadlock if the driver was called from non-schedulable context.
So fix this. The write operation may fail now. It returns the number of
characters accepted. put_char will never fail, since it writes characters
to an intermediate buffer which gets flushed as soon as it is full.
That means the driver now can busy wait if something is in the intermediate
buffer and a write_string operation follows. Seems to be an acceptable
compromise, since that shouldn't happen too often.
