There's no reason for the PXAMCI debug code to print so many lines - it
causes the kernel buffer to overflow when trying to debug this driver.
Remove some debug messages which are duplicated by core code, and
combine other messages, resulting in fewer characters written to the

The CSD contains a "read2write factor" which determines the multiplier to
be applied to the read timeout to obtain the write timeout.  We were
ignoring this parameter, resulting in the possibility for writes being

Patch from Pavel Pisa

The clock starting imxmci_start_clock() function contains hardware
issue workaround, which repeats start attempt, if SDHC does not react on
the first trial. But the second start attempt can be taken even, if the
first succeed and test code misses time limited clock running phase
due to delay caused by schedule to other task or some another device
interrupt. This change enables to detect such situation.
The performance is not issue, because usually at full clock rate
only about six loops in delay cycle are needed.

With CONFIG_SLAB_DEBUG=y networking over qeth doesn't work.  The problem is
that the qib structure embedded in the qeth_irq structure needs an alignment
of 256 but kmalloc only guarantees an alignment of 8.  When using SLAB
debugging the alignment of qeth_irq is not sufficient for the embedded qib
structure which causes all users of qdio (qeth and zfcp) to stop working.
Allocate qeth_irq structure with __get_free_page.  That wastes a small amount
of memory (~2500 bytes) per online adapter.

The dasd state machine is not designed to enable an unformatted device, since
'unformatted' is a final state.  The BIODASDENABLE ioctl calls
dasd_enable_device() which never returns if the device is in this special
state.  Return -EPERM in dasd_increase_state for unformatted devices to make
dasd_enable_device terminate.  Note: To get such an unformatted device online
it has to be re-analyzed.  This means that the device needs to be disabled
prior to re-enablement.
