mdu_array_info_t->size is 'int', which isn't big enough for the size (in KB of
each component in) some arrays.
So rather than a random overflow, set size to -1 when it cannot be set
correctly.
To update aspect on an array, userspace will sometimes:
get_array_info
change one field
set_array_info
in this case, we don't want the '-1' in 'size' to change to size, or look like
a size change at all. So test for that in update_array_info.

As 'array_size' is a 'sector_t', it may overflow inappropriately when shifted
10 bits. So We should cast it to a loff_t first.
There are two places with this problem, but the second (in update_raid_disks)
isn't needed so just remove it:
The only personality that handles ->reshape currently is raid1,
and it doesn't change the size of the array.
When added for raid5/6, reshape again won't change the size of the array,
at least not straight away.
This code might be need for reshaping 'linear' but linear->shape,
if implemented, should probably do the i_size_write itself.

Several bug reports have come in, noting that disabling CONFIG_PCI_MSI
has fixed their problems with this driver. This may be generic system
issues, but there is also the probability of unimplemented hardware
errata workarounds. Until this ream of bug reports is sorted out, we
can get them going in non-MSI interrupt mode.
As such, this change adds an 'msi' module option, which defaults to off.
It seems serial_core intend to initialize port->lock just once for each
ports. This is done in uart_set_options() for console, and in
uart_add_one_port() for other ports. But there is a case the port->lock is
not initialized by serial_core. If the setup function for the console was
failed, it will not call uart_set_options() but the port is marked as
console (uart_console(port) returns 1). It can happen if console was PCI
port which can not detected at the time of register_console.
This patch is to initialize port->lock for such console port. With this
change, most of spin_lock_init() (some of them are labeled "Temporary
fix.") in low-level serial drivers can be omitted.

Clean up the code responsible for the on-disk mirror logs by using the
set_le_bit test_le_bit functions of ext2. That makes the BE machines keep the
bitmap internally in LE order - it does mean you can't use any other type of
operations on the bitmap words but that looks to be OK in this instance. The
efficiency tradeoff is very minimal as you would expect for something that
ext2 uses.
This allows us to remove bits_to_core(), bits_to_disk() and log->disk_bits.
Also increment the mirror log disk version transparently to avoid sharing with

Kernel 2.6.16-rc1 broke the ide-scsi driver: ide-scsi loads but fails to
find any devices to bind to. It also triggers a message "Driver 'ide-scsi'
needs updating - please use bus_type methods" from the driver core.
The IDE core in 2.6.16-rc1 changed the location of an IDE driver's
->probe()/->remove()/->shutdown() methods: they are now in the ide_driver_t
struct not in the gen_driver sub-struct. drivers/ide/ was updated for this
change but ide-scsi.c wasn't. Hence the breakage.
This patch repairs ide-scsi and also eliminates the driver core warning.

Removing and then adding a PCI slot to a running partition results in
a kernel panic. The current code attempts to add iospace for an entire
root bus, which is inappropriate, and silently fails. When a pci device
tries to use the iospace, a page fault is taken, as the iospace had not
been mapped, and of course the page fault cannot be resolved.
This only occurs for PCI adapters using pio, which may be why it hadn't
been seen earlier (this seems to have been broken for a while).
This patch has survived testing of dozens of slot add and removes.

This patch adds the support for isochronous pipe.
A new module parameter is added to select iso mode. It is set to iso by
default because bulk mode doesn't work well at high speed rate (>3 Mbps
for upload).
We use UDSL_IGNORE_EILSEQ flags because ADI firmware doesn't reply to
ISO IN when it has nothing to send [1].
[1]
from cypress datasheet :
The ISOSEND0 Bit (bit 7 in the USBPAIR Register) is used when the EZ-USB
FX chip receives an isochronous IN token while the IN FIFO is empty. If
ISOSEND0=0 (the default value), the USB core does not respond to the IN
token. If ISOSEND0=1, the USB core sends a zero-length data packet in
response to the IN token. The action to take depends on the overall
system design. The ISOSEND0 Bit applies to all of the isochronous IN
endpoints, IN-8 through IN-15.

While the usbatm core has had some support for using isoc urbs
for some time, there was no way for users to turn it on. While
use of isoc transfer should still be considered experimental, it
now works well enough to let users turn it on. Minidrivers signal
to the core that they want to use isoc transfer by setting the new
UDSL_USE_ISOC flag. The speedtch minidriver gets a new module
parameter enable_isoc (defaults to false), plus some logic that
checks for the existence of an isoc receive endpoint (not all
speedtouch modems have one).

Change the module parameters rcv_buf_size and snd_buf_size to
specify buffer sizes in bytes rather than ATM cells. Since
there is some danger that users may not notice this change,
the parameters are renamed to rcv_buf_bytes etc. The transmit
buffer needs to be a multiple of the ATM cell size in length,
while the receive buffer should be a multiple of the endpoint
maxpacket size (this wasn't enforced before, which causes trouble
with isochronous transfers), so enforce these restrictions. Now
that the usbatm probe method inspects the endpoint maxpacket size,
minidriver bind routines need to set the correct alternate setting
for the interface in their bind routine. This is the reason for
the speedtch changes.

This patch causes vcc_release_async to be applied to any open
vcc's when the modem is disconnected. This signals a socket
shutdown, letting the socket user know that the game is up.
I wrote this patch because of reports that pppd would keep
connections open forever when the modem is disconnected.
This patch does not fix that problem, but it's a step in the
right direction. It doesn't help because the pppoatm module
doesn't yet monitor state changes on the ATM socket, so simply
never realises that the ATM connection has gone down (meaning
it doesn't tell the ppp layer). But at least there is a socket
state change now. Unfortunately this patch may create problems
for those rare users like me who use routed IP or some other
non-ppp connection method that goes via the ATM ARP daemon: the
daemon is buggy, and with this patch will crash when the modem
is disconnected. Users with a buggy atmarpd can simply restart
it after disconnecting the modem.

If SCSI commands are submitted while other commands are still processed,
the dispatch loop turns, and we stop the work_timer. Then, if URB fails
to complete, ub hangs until the device is unplugged.
This does not happen often, becase we only allow one SCSI command per
block device, but does happen (on multi-LUN devices, for example).
The fix is to stop timer only when we actually going to change the state.
The nicest code would be to have the timer stopped in URB callback, but
this is impossible, because it can be called from inside a timer, through
the urb_unlink. Then we get BUG in timer.c:cascade(). So, we do it a
little dirtier.

One notable change: the "early handoff" version always enabled
an SMI IRQ ... and did so even if the pre-Linux code said it was
not using EHCI (and not expecting EHCI SMIs). Looks like a goof
in a workaround for some unknown BIOS version.
This merged version only forcibly enables those IRQs when pre-Linux

Convert semaphores to mutexes in mthca. Leave firmware command

Signed-off-by: Roland Dreier <rolandd@cisco.com>
We have run into the following problem: if a task receives a signal
while in the process of e.g. destroying a resource (which could be
because the relevant file was closed) mthca could bail out from trying
to take a command interface semaphore without performing the
appropriate command to tell hardware that the resource is being
destroyed.
As a result we see messages like
ib_mthca 0000:04:00.0: HW2SW_CQ failed (-4)
In this case, hardware could access the resource after the memory has
been freed, possibly causing memory corruption.
A simple solution is to replace down_interruptible() by down() in
command interface activation.

when disabled=1.
Now, in managed mode, iwconfig will not show "TX Power" if the radio is not

The MII registers read/write function blindly busy waits for an
amount of 1000 us (1 ms), then up to 200 ms. These functions are

it triggers lost ticks events. Since the value is way above the
standard delay required for mii register access, it strangely looks
like a bandaid against posted writes.

On occasion, a user will submit a patch that enables the "mod15write"
quirk for their device. Enabling this quirk has the effect of clamping
all ATA commands to no more than 15 sectors. The intended use of this
quirk is to stop the controller from generating FIS's of unusual size
("but Wesley, what about the FOUS's?"), which in turn works around
problems in a <list> of hard drives.
One side effect of this quirk is greatly decreased performance. Users
often enable the mod15write quirk to fix various system, power, chip,
and/or driver problems. For a few rare problematic cases, enabling this
has cured lockups or data corruption.
Rather than add bogus listings to the mod15write quirk list (I get a
patch every month doing such), we add a 'slow_down' module parameter.
This allows users to employ a performance sledgehammer in the hopes
of curing a problem. It defaults to off (0), of course.
