I was working on patches which add new transport error values, when I
noticed that DID_REQUEUE was not in the hostbyte_table. I do not think
there is any way to hit the code path where scsi_show_result is called
and where you return DID_REQUEUE, because DID_REQUEUE causes scsi-ml to
always requeue the command. However, for completeness and because I want
to one day send a patch that tries to add new host bytes values, I am
sending this patch.

 1. Create a file "update_bios" in sysfs to allow user to update bios
    from user space.

 2. The BIOS image file can be downloaded from web site

"http://www.adaptec.com/en-US/downloads/bios_fw/bios_fw_ver?productId=SAS-48300&dn=Adaptec+Serial+Attached+SCSI+48300"
    and copy the BIOS image into /lib/firmware folder.

 3. The aic994xx will accept "update bios_file" and "verify bios_file"
    commands to perform update and verify BIOS image .

    For example:

     Type "echo "update asc483c01.ufi" > /sys/devices/.../update_bios"
          to update BIOS image from /lib/firmware/as483c01.ufi file into
          HBA's flash memory.

     Type "echo "verify asc483c01.ufi" > /sys/devices/.../update_bios"
          to verify BIOS image between /lib/firmware/asc48c01.ufi file
and
          HBA's flash memory.

 4. Type "cat  /sys/devices/.../update_bios" to view the status or
result
    of updating BIOS.

Since the introduction of the acquire_console_sem calls in
0333d835, kexecing can cause the
kernel to deadlock:

 ps3fb_shutdown()
  -> unregister_framebuffer()
  -> fb_notifier_call_chain(FB_EVENT_FB_UNBIND)
  -> fbcon_fb_unbind()
  -> unbind_con_driver()
  -> bind_con_driver()
	[ acquires console_sem ]
  -> fbcon_deinit()
  -> fbops->fb_release(newinfo, 0)
  -> ps3fb_release()
  -> ps3fb_sync()
	[ acquires console_sem ]

This change avoids the deadlock by moving the acquire_console_sem()
out of ps3fb_sync(), and puts it into the two other callsites, leaving
ps3fb_release() to call ps3fb_sync() without the console semaphore.

[Geert]
  - Corrected call sequence above
  - ps3fb_release() may be called with and without console_sem held. This is an
    inconsistency that should be fixed at the fb level, but for now, try to
    acquire console_sem in ps3fb_release().

    I think it's safer to let ps3fb_release() try to acquire console_sem and
    not refresh the screen if it fails, than to call ps3fb_sync() without
    holding console_sem, as ps3fb_par may be modified at the same time, causing
    crashes or lockups.

    Besides, ps3fb_release() only calls ps3fb_sync() to refresh the screen
    when display flipping is disabled, which is an uncommon case (except during
    shutdown/kexec).

The bug causes corruptions of data read from flash.

The original code performs cache invalidation from "adr" to "adr + len"
in do_write_buffer().  Since len and adr could be updated in the code
before invalidation - it causes improper setting of cache invalidation

I noticed that the commit f1974653
(MIPS Tech: Get rid of volatile in core code) broke the software
reset functionality for MIPS Malta boards in big-endian mode.

According to the MIPS Malta board user's manual, writing the magic
32-bit GORESET value into the SOFTRES register initiates board soft
reset. My experimentation has shown that the endianness of the GORESET
integer should thereby be the same as the endianness, which has been
set for the CPU itself. The writew() function used to write the magic
value in the code introduced by the commit mentioned above, however,
swaps bytes for big-endian kernels and transfers 16 bits instead of 32.

The patch below replaces the writew() function by the __raw_writel()
routine, which leaves the byte order intact and transfers the whole
MIPS machine word. Trivial code cleanup (replacing spaces by a tab
and cutting oversized lines to make checkpatch.pl happy) is also
included.

The patch was tested using a Malta evaluation board running in both
BE and LE modes. For both modes, software reset was fully functional
after the change.

P.S. I suspect that the same commit broke the "standby" functionality
for MIPS Atlas boards. However, I did not touch the Atlas code as I
don't have such board at my disposal and also because the linux-mips.org
Web site claims that Atlas support is scheduled for removal.
