There seemed to be another bug introduced as well as a performance hit
with the addtion of the sentinel descriptor workaround. Removal of
this workaround appears to prevent the hang. We'll take a risk
and remove it, as we had never seen the originally reported bug
under linux.

Moved interrupt masking to before requesting the interrupt from the OS.
Moved interrupt enable to after netif_poll_enable. This fixes a racy
BUG() where polling would be running on another CPU at the same time
that netif_poll_enable would run.

This fixes various odd things that missed update together with cpm_uart
platform_device move. Unified resources names, restructurisation, etc.
Also, addressed issue with recent phys/virt translation rework. Being
cache-coherent, CPM2's do alloc_bootmem() for the console stuff, and it was
used to treat console buffer descriptor mapping 1:1 (as in CPM1 case),
which is definitely wrong.

If a SIR dongle is built in the kernel while IRTTY_SIR is built
as a module, kernel compilation will fail.
Thus, the SIR dongle config should depend on the IRTTY_SIR.

Add read/write function pointers to struct nand_ecc_ctrl to
prepare the modulaization of nand_read/write functions. The
current implementation handles every type of ecc mode

schemes in one switch/if construct. Thats too complex to
maintain and too inflexible to expand. Modularization will
also shorten the code pathes of the read/write functions.

If we post a list of length exactly a multiple of 256, nreq in
doorbell gets set to 256 which is wrong: it should be encoded by 0.
This is because we only zero it out on the next WR, which may not be
there. The solution is to ring the doorbell after posting a WQE, not
before posting the next one.
This is the same bug that we just fixed for QPs with non-shared RQ.

It looks like metapage_releasepage was making in invalid assumption that
the releasepage method would not be called on a dirty page. Instead of
issuing a warning and releasing the metapage, it should return 0, indicating
that the private data for the page cannot be released.
I also realized that metapage_releasepage had the return code all wrong. If
it is successful in releasing the private data, it should return 1, otherwise
it needs to return 0.
Lastly, there is no need to call wait_on_page_writeback, since
try_to_release_page will not call us with a page in writback state.

This patch provides a sysfs interface to change some properties of the
ibmveth buffer pools (size of the buffers, number of buffers per pool,
and whether a pool is active). Ethernet drivers use ethtool to provide
this type of functionality. However, the buffers in the ibmveth driver
can have an arbitrary size (not only regular, mini, and jumbo which are
the only sizes that ethtool can change), and also ibmveth can have an
arbitrary number of buffer pools
Under heavy load we have seen dropped packets which obviously kills TCP
performance. We have created several fixes that mitigate this issue,
but we definitely need a way of changing the number of buffers for an
adapter dynamically. Also, changing the size of the buffers allows
users to change the MTU to something big (bigger than a jumbo frame)
greatly improving performance on partition to partition transfers.
The patch creates directories pool1...pool4 in the device directory in
sysfs, each with files: num, size, and active (which default to the
values in the mainline version).
Comments and suggestions are welcome...
