As originally noted by Frederic Temporelli, the aic79xx supports 64
bit addressing, but the initialization code of the driver is wrong: it
tests the available memory size instead of testing the maximum
available memory address.
This patch uses the correct dma_get_required_mask() macros to
determine the correct addressing method.

These changes work compatibly with the old V17 firmware
Contribution:
Ed Chim <ed_chim@adaptec.com>
Gilbert Wu <gilbert_wu@adaptec.com>
Change Log:
1. Use dword instead of qword to display the value of Connection
State register for debug purpose.
2. There are some registers location of AIC94xx chip has been changed
according to the new V28 firmware. The patch has redefined the register
location and provided initialization.
3. The new sequencer firmware v28 for Aic94xx SAS/SATA Linux open
source device driver can be downloaded from

If an EH command times out today, the LLDD's abort handler
will be called to abort the command. It is assumed that this
completes successfully, which can result in the command getting
completed later resulting in an oops. Improve the current
implementation by escalating all the way to host reset if
necessary in order to clean up the EH command.

In asd_initiate_ssp_tmf, the TMF result code is replaced with
TMF_RESP_FUNC_FAILED except when the TMF returns a result code immediately.
However, TMFs can return result codes via an ESCB... yet these codes are
also replaced with "FAILED". The only values that can fall into that case
are TMF_* codes anyway, so get rid of this code where COMPLETE and SUCCESS
are turned into FAILED. This also lets us propagate those TMF_* codes up
to the caller.

libsas: Don't BUG when connecting two expanders via wide port
When a device is connected to an expander, the discovery process goes through
sas_ex_discover_dev to figure out what's attached to the phy. If it is the
case that the phy being discovered happens to be the second phy of a wide link
to an expander, that discover_dev function will incorrectly call
sas_ex_discover_expander, which creates another sas_port and tries to attach the
other sas_phys to the new port, thus triggering a BUG. The correct thing to do is
to check the other ex_phys of the expander to see if there's a sas_port for this
sas_phy, and attach the sas_phy to the existing sas_port.
This is easily triggered if one enables the phys of a wide port between
expanders one by one.
This second version of the patch fixes a small regression in the case where
all the phys show up at once and we accidentally try to attach to a port
that hasn't been created yet.

Write does not trigger this bug because the driver refuses in fixed block
mode writes that are not a multiple of the block size. Read does trigger
it in my system.
The bug is not associated with any specific HBA. st tries to do direct i/o
in fixed block mode with reads that are not a multiple of tape block size.
The patch in this message fixes the st problem by switching to using the
driver buffer up to the next close of the device file in fixed block mode
if the user asks for a read like this.
I don't know why the bug has surfaced only after 2.6.17 although the st
problem is old. There may be another bug in the block subsystem and this
patch works around it. However, the patch fixes a problem in st and in
this way it is a valid fix.
This patch may also fix the bug 7900.
The patch compiles and is lightly tested.

Fusion firmware requires target reset following hotplug removal event,
with purpose to flush target outstanding request in fw. Current implementation
does the target resets from delayed work tasks, that in heavy load
conditions, take too long to be invoked, resulting in command time outs
This patch will issue target reset immediately from ISR context, and will
queue remaining target resets to be issued after the previous one completes.
The delayed work tasks are spawned during the target reset completion.

whereby unneeded and intrusive 'error-handling' would take

Use the same signal frame alignment calculations as the underlying

subtracting 8 * sizeof(struct rt_sigframe) rather than 8 bytes.
