Huawei use the product code HUAWEI_PRODUCT_E353 (0x1506) for a
number of different devices, which each can appear with a number
of different descriptor sets. Different types of interfaces
can be identified by looking at the subclass and protocol fields
Subclass 1 protocol 8 is actually the data interface of a CDC
ECM set, with subclass 1 protocol 9 as the control interface.
Neither support serial data communcation, and cannot therefore
be supported by this driver.
At the same time, add a few other sets which appear if the
device is configured in "Windows mode" using this modeswitch

Found one system with UEFI/iBFT, kernel does not detect the iBFT during
iscsi_ibft module loading.
Root cause: on x86 (UEFI), we are calling of find_ibft_region() much earlier
- specifically in setup_arch() before ACPI is enabled.
Try to split acpi checking code out and call that later
At that time ACPI iBFT already get permanent mapped with ioremap.
So isa_virt_to_bus() will get wrong phys from right virt address.
We could just skip that phys address printing.
For legacy one, print the found address early.
-v2: update comments and description according to Konrad.
-v3: fix problem about module use case that is found by Konrad.
-v4: use acpi_get_table() instead of acpi_table_parse() to handle module use case that is found by Konrad again..

The old PowerMac swim3 driver has some "interesting" locking issues,
using a private lock and failing to lock the queue before completing
requests, which triggered WARN_ONs among others.
This rips out the private lock, makes everything operate under the
block queue lock, and generally makes things simpler.
We used to also share a queue between the two possible instances which
was problematic since we might pick the wrong controller in some cases,
so make the queue and the current request per-instance and use
queuedata to point to our private data which is a lot cleaner.
We still share the queue lock but then, it's nearly impossible to actually
use 2 swim3's simultaneously: one would need to have a Wallstreet
PowerBook, the only machine afaik with two of these on the motherboard,
and populate both hotswap bays with a floppy drive (the machine ships
only with one), so nobody cares...
While at it, add a little fix to clear up stale interrupts when loading
the driver or plugging a floppy drive in a bay.

This function can wait for 5min under certain scenarios. One of them is when
the port is down from switch and bus reset is issued. The bus reset used to
wait for 5 minutes for the loop and upper layer callers used to hang and give
stack trace because of getting stuck for 120 sec. It is legacy code that was
used when the driver used to do queuing of the commands.

mmc_suspend_host() tries to claim host during suspend
and release it only when the bus suspend operation is
compeleted. If CONFIG_MMC_UNSAFE_RESUME is defined and
the host is flagged as removable, mmc_suspend_host()
tries to remove the card. In this process, the file system
sync can get blocked trying to acquire host which is already
claimed by mmc_suspend_host() causing deadlock.
Fix this deadlock by releasing host before ->remove() is called.

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.

When we can't configure the dma channel we want to fall
back to PIO. We do this by setting host->do_dma to zero.
This does not work as do_dma is used to see whether dma
can be used for the current transfer. Instead, we have
to set host->dma to NULL.

This fixes a Data bus error on some SoCs. The first fix for this

ssb: fix init regression of hostmode PCI core
In ssb_pcicore_fix_sprom_core_index() the sprom on the PCI core is
accessed, but the sprom only exists when the ssb bus is connected over
a PCI bus to the rest of the system and not when the SSB Bus is the
main system bus. SoCs sometimes have a PCI host controller and there
this code will not be executed, but there are some old SoCs with an PCI
controller in client mode around and ssb_pcicore_fix_sprom_core_index()
should not be called on these devices too. The PCI controller on these
devices are unused, but without this fix it results in an Data bus
error when it gets initialized.

Once a device is failed we really want to completely ignore it.
It should go away soon anyway.
In particular the presence of bad blocks on it should not cause us to
block as we won't be trying to write there anyway.
So as soon as we can check if a device is Faulty, do so and pretend
that it is already gone if it is Faulty.
