This patch is based on an original patch from Kuan Luo of NVIDIA,
posted under subject "fixed a bug of adma in rhel4u5 with HDS7250SASUN500G".
His description follows. I've reworked it a bit to avoid some unnecessary
repeated checks but it should be functionally identical.
"The patch is to solve the error message "ata1: CPB flags CMD err,
flags=0x11" when testing HDS7250SASUN500G in rhel4u5.
I tested this hd in 2.6.24-rc7 which needed to remove the mask in
blacklist to run the ncq and the same error also showed up.
I traced the bug and found that the interrupt finished a command (for
example, tag=0) when the driver got that adma status is
NV_ADMA_STAT_DONE and cpb->resp_flags is NV_CPB_RESP_DONE.
However, For this hd, the drive maybe didn't clear bit 0 at this moment.
It meaned the hardware had not completely finished the command.
If at the same time the driver freed the command(tag 0) and sended
another command (tag 0), the error happened.
The notifier register is 32-bit register containing notifier value.
Value is bit vector containing one bit per tag number (0-31) in
corresponding bit positions (bit 0 is for tag 0, etc). When bit is set
then ADMA indicates that command with corresponding tag number completed
execution.
So i added the check notifier code. Sometimes i saw that the notifier
reg set some bits , but the adma status set NV_ADMA_STAT_CMD_COMPLETE
,not NV_ADMA_STAT_DONE. So i added the NV_ADMA_STAT_CMD_COMPLETE check
code."

In preparation for supporting NCQ, we must allocate separate SG tables
for each command tag, rather than just a single table per port as before.
Gen-I hardware cannot do NCQ, though, so we still allocate just a single
table for that, but populate it in all 32 slots to avoid special-cases
elsewhere in hotter paths of the code.

Create host-owned DMA memory pools, for use in allocating/freeing per-port

We were checking for the ASYM_PAUSE bit for 1000Base-X twice instead
checking for both the 1000Base-X bit and the 10/100/1000Base-T bit.
The purpose of the logic is to tell the firmware that ASYM_PAUSE is
set on either the Serdes or Copper interface.

rtnl_link_register() fails.
In drivers/net/macvlan.c, when rtnl_link_register() fails in
macvlan_init_module(), there is no point to set it (second time in
this method) to macvlan_handle_frame; macvlan_init_module() will
return a negative number, so instead this patch sets
macvlan_handle_frame_hook to NULL.
