Backport for 3.4-stable for the following patch:
https://lkml.org/lkml/2013/5/10/20
This patch fixes a bug of error handling in Linux MMC driver.
Current MMC driver doesn't handle generic error (bit19 of device
status) in write sequence. As a result, write data gets lost when
generic error
A PCI Based SD Host Controller can support up to a total of six SD Slots, and
the base addresses are specified by Slot Information Register of its PCI header.
Please refer to C.3.3 of SD Host Controller Standard Specification Version 3.0.

Hi,
On next-20130628 I get the following Oops during reboot:

Adds support for sd cards that are locked by a password and rereading an
already enumerated card.
This fixes compatibility issues with password locked cards as they would
not enumerate correctly when detecting them. The card side locking
functionality is specified as mandatory in the Physical
Add commands for locking and unlocking SD cards by password. This is to be used
in conjunction with a kernel that enumerates locked sd cards and provides an
ioctl
for rereading the card after unlocking.

It looks like commit 7628774 mmc: core: Handle card shutdown from
mmc_bus causes a crash during reboot at least on Tegra platforms. The
issue appears to be in:
static void mmc_bus_shutdown(struct device *dev)
{
struct mmc_driver *drv = to_mmc_driver(dev-driver);
struct mmc_card

only sd0 has the issue that WP is inverted, so we drop the global set of
SDHCI_QUIRK_INVERTED_WRITE_PROTECT and only enable the wp-inverted prop
for sd0 in dts.
