Hi,
This is a patch to incorporate comments from earlier 12 patches.
It also fixes a few issues we found during this time.
Following is a list of changes in this patch. Item 1 incorporates
earlier comments. Issues addressed in items 2 to 4 were discovered
recently.

1. wmb() call in s2io_xmit() replaced with mmiowb().
2. The dtx_control register was earlier programmed incorrectly
   for Xframe II adapter.
3. As suggested by hardware team, after a reset, in case of
   Xframe II adapter, we clear certain spurious errors by
   clearing PCI-X ECC status register, "detected parity error"
   bit in PCI_STATUS register and PCI_STATUS bit in txpic_int register.
4. On IBM PPC platforms, we found that in the Rx buffer replenish
   function, two memory writes(one to the the descriptor length and
   another to the ownership) were getting reordered. This was causing
   the adapter to see the ownership transfered to it before the length
   was updated.

   One solution was to add a wmb() but since this would turnout expensive
   on some platforms if called for every descriptor, we set the ownership
   bit and other fields of '2' to 'N' Rx descriptors followed by a wmb()
   and then set the ownership of first descriptor ('1').

   Here the value 'N' is configurable by making it a module loadable
   parameter (rxsync_frequency).
   (NOTE: This parameter is a power of 2).
5. Bumped up the driver version no. to 2.0.2.1

Hi,
The last patch in this series fixes the following issues found during
testing.
1. Ensure we don't pass zero sized buffers to the card(which can lockup)
2. Restore the PCI-X parameters(in case of Xframe I adapter) after a reset.
3. Make sure total size of all FIFOs does not exceed 8192.

Hi,
This is a patch to provide bimodal interrupt moderation support for
Xframe II adapter. Basically, in this moderation scheme, the adapter
raises a traffic interrupt if the no. of packets transmitted and/or
received reaches a programmable threshold.

Hi,
This patch provides basic support for the Xframe II adapter.
Includes the following changes:
1. New values to program XAUI interface.
2. Print the PCI/PCI-X mode(bus frequency, width).
3. Remove EOI from reset during intialization.
4. Enable all 8 PCCs if Xframe II adapter.
5. Programs the RLDRAM size depending on the device.
(Note: RLDRAM size on XFARME-I is 64Mb whereas on XFRAME-II it's 32 Mb).
6. Enable extended(64-bit) statistics counters.
7. Program timer interrupt duration based on PCI/PCI-X clock speed.
8. Not required to save/restore PCI config space before/after reset.

Hi,
This patch relates to mostly performance related changes.
1. Fixed incorrect computation of PANIC level in rx_buffer_level().
2. Removed unnecessary PIOs(read/write of tx_traffic_int and
   rx_traffic_int) from interrupt handler and removed read of
   general_int_status register from xmit routine.
3. Enable two-buffer mode(for Rx path) automatically for SGI
   systems. This improves Rx performance dramatically on
   SGI systems.

Hi,
Below patch includes fixes for few purely software bugs identified
since last release.
1. Keep track and display(as part of ethtool command output) the no.
   of single-bit and double-bit ECC errors.
2. Handle race condition between intr handler and "interface down"
   routine.
3. Initial link state setting modified so that the link state displayed
   after "interface Up" is correct.
4. Fix for "Incorrect Tx packet count when TSO is enabled".
5. Disable periodic DMA of statistics and schedule one-shot DMA
   only when required.

Hi,
Below patch addresses few h/w specific issues.
1. Check for additional ownership bit on Rx path before
   starting Rx processing.
2. Enable only 4 PCCs(Per Context Controller) for Xframe I
   revisions less than 4.
3. Program Rx and Tx round robin registers depending on
   no. of rings/FIFOs.
4. Tx continous interrupts is now a loadable parameter.
5. Reset the card if we get double-bit ECC errors.
6. A soft reset of XGXS being done to force a link state change has been
   eliminated.
7. After a reset, clear "parity error detected" bit,
   PCI-X ECC status register, and PCI_STATUS bit in
   tx_pic_int register.
8. The error in the disabling allmulticast implementation has been
   rectified.
9. Leave the PCI-X parameters MMRBC, OST etc. at their
   BIOS/system defaults.

We have a chek in there to make sure that the name won't overflow
task_struct.comm[], but it's triggering for scsi with lots of HBAs, only
scsi is using single-threaded workqueues which don't append the "/%d"
anyway.

All too hard.  Just kill the BUG_ON.

Need to use list_for_entry_safe(), as we're removing items during the
traversal.  list_for_each_entry() uses the first ptr also as an iterator, if
you kfree() it slab takes it, might poison it and then you try to use it to
iterate to the next object in list.

Yet another hack due to the fact that libata is the only user of SCSI's
->eh_strategy_handler() hook.

 sata_sx4 directly references sg->length to calculate total_len in
pdc20621_dma_prep().  This is incorrect as dma_map_sg() could have
merged multiple sg's into one and, in such case, sg->length doesn't
reflect true size of the entry.  This patch makes it use
sg_dma_len(sg).

Unfortunately, we can't use the "user" bit in the page tables to
control whether a page table entry is "global" or "asid" specific,
since the vector page is mapped as "user" accessible but is not
process specific.

Therefore, give direct control of the ARMv6 "nG" (not global)
bit to the mm layers.
