There are 3 kinds of headers included in the bus driver components--
misc linux/include files, public bus driver includes, and includes
private to the bus driver.
Cleanup the order and formatting of includes in the bus driver to be
consistent:
#include <linux/include/[file].h>
#include ../include/[file].h // public bus driver includes (eventually
// destined for: linux/include/fsl)
[blank line]
#include "[file].h" // private bus driver includes

An mc-io is a software abstraction of a dpmcp object (an MC portal).
Routines to create/initialize/reset this portal abstraction were split
between the allocator and mc-sys.c (MC command interface). Move
mc-io/portal related definitions into one source file.

The mc- prefix on the source files names of some internal components
of the fsl-mc bus driver makes things less clear that they could be.
The string "mc" generally refers to hardware-- the physical DPAA
'management complex'. Names like "mc-allocator.c" have nothing to
with the "MC" hardware per se. Improve clarity by using the prefix
string "fsl-mc" instead which is what we are calling this bus.

The definitions in mc-private.h are not strictly speaking

accurately reflect expected use.

The semaphore 'lock' in 'pwrctrl_priv' is used as a simple mutex, so it
should be written as one. Semaphores are going away in the future.
_enter_pwrlock was using down_interruptible(), so the lock could be broken
by sending a signal. This could be a bug, because nothing checks the return
code here. Hence, using mutex_lock instead of the interruptible version.
Removing the now unused _enter_pwrlock and _down_sema.

Currently it is not possible to send LNet traffic between
two nodes using infiniband hardware that have different
page sizes for the case when RDMA fragments are used.
When two nodes establish a connection they tell the other
node the maximum number of RDMA fragments they support.
The issue is that the units are pages, and 256 64K pages
corresponds to 16MB of data, whereas a 4K page system is
limited to messages with 1MB of data. The solution is to
report over the wire the maximum number of fragments in
4K unites regardless of the native page size. The recipient
then uses its native page size to translate into the
maximum number of pages sized fragments it can send to
the other node.

ll_find_alias is responsible for getting alias for inode
which can be reused. Directories are assumed to have unique
alias, where in case of non-directories there can be multiple
aliases. In case of lustre there can be two type of aliases
i.e. discon_alias and invalid_alias. Usage of discon_alias in
case of non-directories may corrupt dcache and leads to kernel
crash. Changes made to avoid use of discon_alias in case of
non-directories.
