commit f0342e66b397947ed8c3eef8c37b5ca2d5b1bb50 upstream.
In order to ensure the correct width cycles on the VME bus, the VME bridge
drivers implement an algorithm to utilise the largest possible width reads and
writes whilst maintaining natural alignment constraints. The algorithm
currently looks at the start address rather than the current read/write address
when determining whether a 16-bit width cycle is required to get to 32-bit
alignment. This results in incorrect alignment,

put_device() must be called after device_register() fails,
since device_register() always initializes the refcount
on the device structure.

Since we will be removing items off the list using list_del() we need
to use a safer version of the list_for_each() macro aptly named
list_for_each_safe(). We should use the safe macro if the loop
involves deletions of items.

The memcpy_fromio() and memcpy_toio() functions use the __memcpy() function,
at least on x86. This function carries out transfers smaller than 32 bits as
multiple 8 bit transfers, causing a single (aligned) 16 bit transfer to be
split into 2 8 bit transfers which may not be supported by the target VME
device.
The commit 53059aa059 fixed this for the
ca91cx42, however this was not fixed for the tsi148 at the time. This patch
uses the same algorithm to fix the tsi148.

This moves the VME core, VME board drivers, and VME bridge drivers out
of the drivers/staging/vme/ area to drivers/vme/.
The VME device drivers have not moved out yet due to some API questions
they are still working through, that should happen soon, hopefully.
