Wei Yongjun 43f5e46c8e vme: vme_ca91cx42.c: use list_for_each_safe() when delete list items
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.

Martyn Welch 363e2e6f9e VME: Prevent D16 cycles being split into 8-bit blocks
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.

Greg Kroah-Hartman db3b9e990e Staging: VME: move VME drivers out of staging
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.
