Incrementing the timeout count value that we stuff into the TIMEOUT_CONTROL register gets us a value that works. This bug was originally discovered by Pierre Ossman, I believe.

The Marvell CaFe chip's SD implementation chokes during card insertion if one attempts to set the voltage and power up in the same SDHCI_POWER_CONTROL register write. This adds a quirk that does that particular dance in two steps. It also adds an entry to pci_ids.h for the CaFe chip's SD device.

Most Smart Array controllers can support up to 1024 commands, the notable exceptions are the E200 and E200i. The next generation of controllers which were just added support a mode of operation called Zero Memory Raid (ZMR). In this mode they only support 64 outstanding commands. In Full Function Raid (FFR) mode they support 1024. We have been setting the queue depth by arbitrarily assigning some value for each controller. We needed a better way to set the queue depth to avoid lots of annoying "fifo full" messages. So we made the driver a little smarter. We now read the config table and subtract 4 from the returned value. The -4 is to allow some room for ioctl calls which are not tracked the same way as io commands are tracked. Please consider this for inclusion.

As I never saw that before, I thought about hardware problems. But in fact it is a bug in the Linux kernel. The end of the rodata section is marked with the "__end_rodata" symbol. This symbol have different aligning constraints than the inittext parts and therefor the start marked "_sinittext". Because of that the __end_rodata symbol shifts between < _sinittext and == _sinittext. The later variant is seen as a code symbol and recorded in the kallsyms data. On fix would be to move the exception table a little bit and get some space between that two areas.
