Akinobu Mita 37d54111c1 [PATCH] bitops: hweight() related cleanup
By defining generic hweight*() routines

- hweight64() will be defined on all architectures
- hweight_long() will use architecture optimized hweight32() or hweight64()

I found two possible cleanups by these reasons.

Stefan Richter a80614d1ad sbp2: update 36byte inquiry workaround (fix compatibility regression)
Since about Linux 2.6.14, sbp2's inquiry workaround did not work anymore
due to changes in the SCSI layer. Update it to become effective again.
Testing one of the two known affected bridges has shown that skip_ms_page_8
is required as well.

Also, make force_inquiry_hack tunable via /sys/module/sbp2/parameters.

Stefan Richter 35bdddb83f sbp2: variable status FIFO address (fix login timeout)
Let the ieee1394 core select a suitable 1394 address range for sbp2's
status FIFO instead of using a fixed range. Since the core only selects
addresses which are guaranteed to be out of the "physical range" as per
OHCI 1.1, this patch also fixes an old bug:

OHCI controllers which implement a writeable PhysicalUpperBound register
included sbp2's status FIFO in the physical range. That way sbp2 was
never notified of a succesful login and always failed after timeout.
Affected OHCI host adapters include ALi and Fujitsu controllers.

As another side effect of this patch, the status FIFO is no longer
located in a range for which OHCI chips perform "posted writes". Each
status write now requires a response subaction. But since large data
transfers involve only few status writes, there is no measurable
decrease of I/O throughput. What's more, the status FIFO is now safe
from potential host bus errors. Nevertheless, posted writes could be
re-enabled by extensions to the ARM features of the 1394 stack.

Stefan Richter bf637ec3ef sbp2: fix another deadlock after disconnection
If there were commands enqueued but not completed before an SBP-2 unit
was unplugged (or an attempt to reconnect failed), knodemgrd or any
process which tried to remove the device would sleep uninterruptibly
in blk_execute_rq().  Therefore make sure that all commands are
completed when sbp2 retreats.

Al Viro e30809fde5 [PATCH] don't mangle INQUIRY if cmddt or evpd bits are set
sbp2.c mangles INQUIRY response in a way that only applies to standard
inquiry data (i.e. when both cmddt and evpd bits are 0).  Leave other cases
alone; e.g. when asking for VPD the length of reply is in byte 3, not 4
and byte 4 is the first byte of device serial number.

Stefan Richter d51e86c18a ieee1394: write broadcast_channel only to select nodes (fixes device recognition)
Some old 1394-1995 SBP-2 bridges would hang if they received a broadcast write
request to BROADCAST_CHANNEL before the config ROM was read.  Affected devices
include Datafab MD2-FW2 2.5" HDD and SmartDisk VST FWCDRW-V8 portable CD writer.
The write request is now directed to specific nodes instead of being broadcast
to all nodes at once, and it is only performed if a previous read request at
this register succeeded.

Stefan Richter 51c1d80e92 ieee1394: run high-level updates before high-level probes
After a bus reset, let nodemgr call high-level update hooks first for nodes
which do not need to be probed.  The main benefit is for a bus with more
than one SBP-2 device:  SBP-2 reconnects will be performed before SBP-2
logins, thus have a much higher chance to succeed, and their SCSI devices
will not be blocked much longer than necessary.  This was demonstrated for
Linux 2.4 by Dave Cinege a while ago.

A better approach would be to perform time-consuming probes in parallel by a
subthread.  I actually plan to implement this for sbp2 but it may take a
while to get that done and tested.  Until then, this tweak is a huge
improvement for users with multiple SBP-2 devices.
