mbcache used several different types to represent the number of entries
in the cache. For consistency within mbcache and with the shrinker API,
always use unsigned long.
This does not change behavior for current mbcache users (ext2 and ext4)
since they limit the entry count to a value which easily fits in an int.

When mbcache is built as a module, any modules that use it (ext2 and/or
ext4) will depend on its symbols directly, incrementing its reference
count. Therefore, there is no need to do module_get/module_put.
Also note that since the module_get/module_put were in the mbcache
module itself, executing those lines of code was already dependent on
another reference to the mbcache module being held.

As of commit 8f32b90981dcdb355516fb95953133f8d4e6b11d
("net: ethernet: ti: davinci_cpdma: add set rate for a channel") the
ARM allmodconfig builds would fail modpost with:
ERROR: "cpdma_chan_set_weight" [drivers/net/ethernet/ti/ti_cpsw.ko] undefined!
ERROR: "cpdma_chan_get_rate" [drivers/net/ethernet/ti/ti_cpsw.ko] undefined!

ERROR: "cpdma_chan_set_rate" [drivers/net/ethernet/ti/ti_cpsw.ko] undefined!
Since these weren't declared as static, it is assumed they were
meant to be shared outside the file, and that modular build testing
was simply overlooked.

mbcache entries have an 'e_referenced' bit which users can set with
mb_cache_entry_touch() to indicate that an entry should be given another
pass through the LRU list before the shrinker can delete it. However,
mb_cache_shrink() actually would, when seeing an e_referenced entry at
the front of the list (the least-recently used end), place it right at
the front of the list again. The next iteration would then remove the
entry from the list and delete it. Consequently, e_referenced had
essentially no effect, so ext2/ext4 xattr blocks would sometimes not be
reused as often as expected.
Fix this by making the shrinker move e_referenced entries to the back of
the list rather than the front.

As David Miller pointed out for for the previous patch, the whitespace
in some functions looks rather odd. This was caused by commit 6329da5f258a
("obsolete config in kernel source: USE_INTERNAL_TIMER"), which removed
some conditions but did not reindent the code.
This fixes the indentation in the file and removes extraneous whitespace
at the end of the lines and before tabs.
There are many other minor coding style problems in the driver, but I'm
not touching those here.

If the resources of cq are freed while executing the user case, hardware
can not been notified in hip06 SoC. Then hardware will hold on when it
writes the cq buffer which has been released.
In order to slove this problem, RoCE driver checks the CQE counter, and
ensure that the outstanding CQE have been written. Then the cq buffer
can be released.

If the resources of mr are freed while executing the user case, hardware
can not been notified in hip06 SoC. Then hardware will hold on when it
reads the payload by the PA which has been released.
In order to slove this problem, RoCE driver creates 8 reserved loopback
QPs to ensure zero wqe when free mr. When the mac address is reset, in
order to avoid loopback failure, we need to release the reserved loopback
QPs and recreate them.

If send queue is still working when qp is in reset state by modify qp
in destroy qp function, hardware will hold on and don't work in hip06
SoC. In current codes, RoCE driver check hardware pointer of sending and
hardware pointer of processing to ensure that hardware has processed all
the dbs of this qp. But while the environment of wire becomes not good,
The checking time maybe too long.
In order to solve this problem, RoCE driver created a workqueue at probe
function. If there is a timeout when checking the status of qp, driver
initialize work entry and push it into the workqueue, Work function will
finish checking and release the related resources later.

IB core has implemented the calculation of GIDs and the management
of GID tables, and it is now responsible to supply query function
for GIDs. So the calculation of GIDs and the management of GID
tables in the RoCE driver is redundant.
The patch is to implement the add_gid/del_gid to set the GIDs in
the RoCE driver, remove the redundant calculation and management of
GIDs in the notifier call of the net device and the inet, and
update the query_gid.

This patch modified the condition of notifying hardware loopback.
In hip06, RoCE Engine has several ports, one QP is related
to one port. hardware only support loopback in the same port,
not in the different ports.
So, If QP related to port N, the dmac in the QP context equals
the smac of the local port N or the loop_idc is 1, we should
set loopback bit in QP context to notify hardware.
