Use the newly introduced pci_ioremap_bar() function in drivers/i2c.
pci_ioremap_bar() just takes a pci device and a bar number, with the goal
of making it really hard to get wrong, while also having a central place
to stick sanity checks.

For ethernet support, we need to reserve QPs for the ethernet and
fibre channel driver. The QPs are reserved at the end of the QP
table. (This way we assure that they are aligned to their size)
We need to consider these reserved ranges in bitmap creation, so we
extend the mlx4 bitmap utility functions to allow reserved ranges at
both the bottom and the top of the range.

This patch (as1152) may help prevent some problems associated with the
new policy of unbinding drivers that don't support suspend/resume or
pre_reset/post_reset. If for any reason the resume or reset fails, and
the device is logically disconnected, there's no point in trying to
rebind the driver. So the patch checks for success before carrying
out the unbind/rebind.
There was a report from one user that this fixed a problem he was
experiencing, but the details never became fully clear. In any case,
adding these tests can't hurt.

In this patch, we want to do one thing: add more Huawei product IDs into the
USB driver. Then it can support more Huawei data card devices. So to declare
the unusual device for new Huawei data card devices in unusual_devs.h and to
declare more new product IDs in option.c.
To modify the data value and length in the function of
usb_stor_huawei_e220_init in initializers.c That's because based on the USB
standard, while sending SET_FETURE_D to the device, it requires the
corresponding data to be zero, and its sending length also must be zero. In
our old solution, it can be compatible with our WCDMA data card devices, but
can not support our CDMA data card devices. But in this new solution, it can
be compatible with all of our data card devices.
