Fixes for deadlocks of the ieee1394 and scsi subsystems and long delays in
futile error recovery attempts when SBP-2 devices are removed or drivers are
unloaded.
- Complete commands quickly with DID_NO_CONNECT if the 1394 node is gone or if
the 1394 low-level driver was unloaded.
- Skip unnecessary work in the eh_abort_handler and eh_device_reset_handler if
the node or 1394 low-level driver is gone.
- Let scsi's high-level shut down gracefully when sbp2 is being unloaded or
detached from the 1394 unit. A call to scsi_remove_device is added for this
purpose, which requires us to store a scsi_device pointer.
- scsi_device pointer is obtained from slave_alloc hook and cleared by
slave_destroy. This avoids usage of the pointer after the scsi device was
deleted e.g. by the user via scsi_mod's sysfs interface.

This change removes a bogus error message from the IOC4 serial driver
interrupt handler.
This error message is bogus for two reasons. First, it can never occur
given that current code takes care to initialize IOC4 in such a way that
these "unknown" interrupts could never occur. Second, this code fails to
take into account that other drivers can share the IOC4 interrupt mechanism
through SA_SHIRQ, and thus this driver is not in-fact "all-knowing".
Finally, this error message triggers every time some "unknown" interrupt
occurs -- it's not rate limited or repetition limited in any way, thereby
effectively denying use of the console device. Given its bogosity in the
first place, it's best to just get rid of it entirely.

When creating a multipath device, if the queue_if_no_path parameter is
specified it gets ignored.
While the queue_if_no_path variable is correctly set to 1, the
saved_queue_if_no_path gets set to 0. When the device is subsequently made
live (resumed), the saved value (0) always overwrites the live value (1) so
the option *always* gets turned off.
The fix adds a parameter to the queue_if_no_path() function to indicate
whether the previous value should be preserved or not - if not, as when the
device is being set up, the saved value is set to the new value (1).

The current kernel contains a very crude driver that doesn't do much more
than reading the real time clock synchronously. This is a completely
rewritten driver that provides interrupt based command queuing, a userland

Addresses some small bugs in the pegasus ethernet-over-USB driver.
Specifically, malformed long packets from the adapter could cause a kernel
panic; the interrupt interval calculation was inappropriate for high-speed
devices; the return code from read_mii_word was tested incorrectly; and
failure to unlink outstanding URBs before freeing them could lead to kernel
panics when unloading the driver.

- Elminate memory leak on one (rare) disable/shutdown path.
- For periodic transfers that don't need to be scheduled, update
urb->start_frame to represent the transfer phase correctly.
- Report the (single) port as removable, by default.
Since no drivers yet use start_frame or that part of the hub descriptor,

I'm using a 2 port USB RS232 dongle to connect to a serial-IR cradle for
a bar code reader). Detecting the baudrate of the serial-IR involves
keeping DTR low while changing baudrate.
This works using normal 16550A serial ports as well as the FTDI driver
version 1.4.0 (Linux 2.6.8) but stopped working with the change to
"ensure RTS and DTR are raised when changing baudrate" introduced in
version 1.4.1 (Linux 2.6.9).
The attached patch fixes this, so RTS and DTR is only raised when
changing baudrate iff the previous baudrate was B0.

This function expects an unsigned 32-bit type as its third argument:
static u32 pci_size(u32 base, u32 maxbase, u32 mask)
However, given these definitions:
#define PCI_BASE_ADDRESS_MEM_MASK (~0x0fUL)
#define PCI_ROM_ADDRESS_MASK (~0x7ffUL)
these two calls in drivers/pci/probe.c are problematic for architectures
for which a UL is not equivalent to a u32:
sz = pci_size(l, sz, PCI_BASE_ADDRESS_MEM_MASK);
sz = pci_size(l, sz, PCI_ROM_ADDRESS_MASK);

The class symlinks in sysfs don't properly handle changing device names.
To demonstrate, rename your network device from eth0 to eth1. Your

bus_rescan_devices_helper() does not hold the dev->sem when it checks for
!dev->driver(). device_attach() holds the sem, but calls again
device_bind_driver() even when dev->driver is set.
What happens is that a first device_attach() call (module insertion time)
is on the way binding the device to a driver. Another thread calls
bus_rescan_devices(). Now when bus_rescan_devices_helper() checks for
dev->driver it is still NULL 'cos the the prior device_attach() is not yet
finished. But as soon as the first one releases the dev->sem the second
device_attach() tries to rebind the already bound device again.
device_bind_driver() does this blindly which leads to a corrupt
driver->klist_devices list (the device links itself, the head points to the
device). Later a call to device_release_driver() sets dev->driver to NULL
and breaks the link it has to itself on knode_driver. Rmmoding the driver
later calls driver_detach() which leads to an endless loop 'cos the list
head in klist_devices still points to the device. And since dev->driver is
NULL it's stuck with the same device forever. Boom. And rmmod hangs.
Very easy to reproduce with new-style pcmcia and a 16bit card. Just loop
modprobe <pcmcia-modules> ;cardctl eject; rmmod <card driver, pcmcia
modules>.
Easiest fix is to check if the device is already bound to a driver in
device_bind_driver(). This avoids the double binding.

Summary of Changes:
* splitting mpt_interrupt per Christophs suggestion
about a month ago
* rename ScsiCfgData to SpiCfgData structure,
then move all the raid related info into
new structure called RaidCfgData. This is
done because SAS supports RAID, as well as SPI,
so the raid stuff should be seperate.
* incorrect timeout calculation for cntdn
inside WaitForDoorbellAck and WaitForDoortbellInt
* add support for interpreting SAS Log Info
* Increase Event Log Size from 0xA to 0x32
* Fix bug in mptsas/mptfc/mptspi - when controller
has Initiator Mode Disabled, and only running in
TargetMode, the mptctl would panic when loading.
The fix is to return 0, instead of -ENODEV, in
SCSI LLD respective probe routines
* Fix bug in mptlan.c - driver will panic if
there is host reset, due to dev being set to
zero in mpt_lan_ioc_reset
* Fix's for SPI - Echo Buffer
* Several fix's in mptscsih_io_done - FCP Response
info, RESIDUAL_MISMATCH, Data Underrun, etc.
* Cleanup Error Handling - EH handlers,
mptscsih_flush_cmds, and zeroing out ScsiLookup
from mptscsih_qcmd
* Cleanup asyn event handling from
mptscsih -> mptscsih_event_process. Also
added support for SAS Persistent Table Full,

This patch (as545) fixes the list traversals in __scsi_remove_target and
scsi_forget_host. In each case the existing code list_for_each_entry_safe
in an _unsafe_ manner, because the list was not protected from outside
modification while the iteration was running.
The new scsi_forget_host routine takes the moderately controversial step
of iterating over devices for removal rather than iterating over targets.
This makes more sense to me because the current scheme treats targets as
second-class citizens, created and removed on demand, rather than as
objects corresponding to actual hardware. (Also I couldn't figure out any
safe way to iterate over the target list, since it's not so easy to tell
when a target has already been removed.)

BUG fixes:
The driver used to allocate memory with spinlock held which has been
fixed in this patch.
The driver was printing the entire buffer when it received a invalid
entry in image_type. The fix is to only print a warning message and not
the buffer.
Usability enhancements:
It is possible that due to user error the /sys/class/firmware/dell_rbu
entries might be missing, this can happen if the user does the following
echo 1 > /sys/class/firmware/dell_rbu/loading
echo 0 > /sys/class/firmware/dell_rbu/loading
This will make the entries in /sys/class/firmware/ to disappear and the
only way get them back was bby unloading and loading the driver.
This patch makes the user recreate these entries by echoing init in to
image_type.
This patch has been tested with Libsmbios and Dell OpenManage.

Got confused with the crypto update. The last patch added a call to
destroy_workqueue() for a non-existent workqueue with the comment "Remove
device workqueue on module unload". This is nonsense. Remove the offending

Fix and simplify the workaround code for the 4GB boundary tx buffer
hardware bug.
1. Need to unmap the original SKB's dma addresses if a new SKB cannot
be allocated.
2. Need to pass the base flag to tigon3_4gb_hwbug_workaround() or TSO
won't work properly.
3. The guilty entry and length parameters for
tigon3_4gb_hwbug_workaround() are removed as they are not necessary.
4. Remove assumption that only one fragment can hit the 4GB boundary.
Another fragment can hit 8GB for example.

Make sure we that completion is the final action we take; prior to this
change, another CPU may have changed ap->pio_task_state before we tested
it a final time.
Spotted by, and original patch by Albert Lee @ IBM.
Also includes a minor optimization: eliminate a ton of unnecessary
queue_work() calls, simply by jumping to the beginning of the FSM
function ata_pio_task().
This patch makes the driver work with any BladeCenter
network switch, it used to work only with certain
models.
Please apply.

Reported by: walt <wa1ter@myrealbox.com>
"I routinely switch the console font during bootup to
8x8 so I can get 50 lines per screen. Until 09 Sept,
just changing to the small font automatically gave me
all 50 lines -- but now I'm only getting 25 lines even
with the small font. The bottom half of the screen
displays the text that already scrolled off the top."
This bug is due to an erroneous check in the recently added hook,
vgacon_resize(). It checks the new height against the original number of
rows of the console. Because the original number of rows depends on both
the scanline and the font height, check it instead against the
scanline/fontheight.

The virt_to_bus() wasn't correctly taken out of this driver. It needs
to be able to track both physical and virtual addresses for its prd table.
Update the driver to do this with separate tracking entries.
