R300 family will hard lockup if host path read cache flush is
done through MMIO to HOST_PATH_CNTL. But scheduling same flush
through ring seems harmless. This patch remove the hdp_flush
callback and add a flush after each fence emission which means
a flush after each IB schedule. Thus we should have same behavior
without the hard lockup.
Tested on R100,R200,R300,R400,R500,R600,R700 family.

The Davicom DM9100 and DM9102 chips are used on the motherboards of
some SPARC systems (supported by the tulip driver) and also in PCI
expansion cards (supported by the dmfe driver). There is no
difference in the PCI device ids for the two different configurations,
so these drivers both claim the device ids. However, it is possible
to distinguish the two configurations by the presence of Open Firmware

For any given clock we can use the find_pll to get the corresponding DPLL
setting. It is unnecessary to use the find_reduce_pll callback function
to calculate the DPLL parameter for LVDS downclock in order to get the same
divider factor(P) for the normal and downclock.
In theory when the LVDS downclock is supported by LVDS panel, we should get the
same DPLL divider factor(P) for the normal clock and reduced downclock.
If we get the diferent divider factor(P) for normal clock and reduced downclock,
it means that the found downclock is incorrect and should be discarded.
So we should use find_pll callback to calculate the DPLL parameter for the
LVDS reduced downclock as for the normal clock. Then we can do the cleanup
about find_reduced_pll.

For configurations where Synaptics hardware is present but the Synaptics
extensions support is not compiled in, the mouse is reprobed and a new
device is allocated on every suspend/resume.
During probe, psmouse_switch_protocol() calls psmouse_extensions() with
set_properties=1. This calls the dummy synaptics_init() which returns an
error code, instructing us not to use the synaptics extensions.
During resume, psmouse_reconnect() calls psmouse_extensions() with
set_properties=0, in which case call to synaptics_init() is bypassed and
PSMOUSE_SYNAPTICS is returned. Since the result is different from previous
attempt psmouse_reconnect() fails and full re-probe happens.
Fix this by tweaking the set_properties=0 codepath in psmouse_extensions()
to be more careful about offering PSMOUSE_SYNAPTICS extensions.

If NET_SKB_PAD is not a multiple of the cache line size, mv643xx_eth
allocates a couple of extra bytes at the start of each receive buffer
to make the data payload end up on a cache line boundary.
These extra bytes are skb_reserve()'d before DMA mapping, so they
should not be included in the DMA map byte count (as the mapping is
done starting at skb->data), nor should they be included in the
receive descriptor buffer size field, or the hardware can end up
DMAing beyond the end of the buffer, which can happen if someone
sends us a larger-than-MTU sized packet.
This problem was introduced in commit 7fd96ce47f ("mv643xx_eth:
rework receive skb cache alignment", May 6 2009), but hasn't appeared
to be problematic so far, probably as the main users of mv643xx_eth
all have NET_SKB_PAD == L1_CACHE_BYTES.

it conflicts with some other register settings and can cause problems.

reclocking is supported, so I'm leaving that bit.

When using realtime signals, we'll enqueue one signal for every event.
This is unfortunate, because (for example) keyboard presses are three
events: key, msc scancode, and syn. They'll be enqueued fast enough in
kernel space that all three events will be ready to read by the time
userspace runs, so the first invocation of the signal handler will read
all three events, but then the second two invocations still have to run
to do no work.
Instead, only send the SIGIO notification on syn events. This is a
slight abuse of SIGIO semantics, in principle it ought to fire as soon
as any events are readable. But it matches evdev semantics, which is
more important since SIGIO is rather vaguely defined to begin with.

sysfs_remove_group() waits for sysfs attributes to be removed, therefore
we do not need to worry about driver-specific attributes being accessed
after driver has been detached from the device. In fact, attempts to take
serio->drv_mutex in attribute methods may lead to the following deadlock:
sysfs_read_file()
fill_read_buffer()
sysfs_get_active_two()
psmouse_attr_show_helper()
serio_pin_driver()
serio_disconnect_driver()
mutex_lock(&serio->drv_mutex);
<--------> mutex_lock(&serio_drv_mutex);
psmouse_disconnect()
sysfs_remove_group(... psmouse_attr_group);
....
sysfs_deactivate();
wait_for_completion();
Fix this by removing calls to serio_[un]pin_driver() and functions themselves
and using driver-private mutexes to serialize access to attribute's set()
methods that may change device state.

It turns out that some PCI devices require extra delays when changing
power state from D3 to D0 (and the other way around). Although this
is against the PCI specification, we can handle it quite easily by
allowing drivers to define arbitrary D3 delays for devices known to
require extra time for switching power states.
Introduce additional field d3_delay in struct pci_dev and use it to
store the value of the device's D0->D3 delay, in miliseconds. Make
the PCI PM core code use the per-device d3_delay unless
pci_pm_d3_delay is greater (in which case the latter is used).
[This also allows the driver to specify d3_delay shorter than the
10 ms required by the PCI standard if the device is known to be able
to handle that.]
Make the sky2 driver set d3_delay to 150 for devices handled by it.

updating the code to consider devices with custom EEPROM sizes.
Devices with custom sized EEPROMs have the upper limit size stuffed
in the EEPROM. Use this as the upper limit instead of the static
default size. In case of a checksum error also provide back the
max size and whether or not this was the default size or a custom
one. If the EEPROM is busted we add a failsafe check to ensure
we don't loop forever or try to read bogus areas of hardware.

During a manual scan, a user can send command to a nonexistent
lun, precisely at the point of max_lun. Normally it's possible
(but not required) that the firmware has the knowledge that it
is an invalid lun. In the particular case when max_lun is 256,
however, the nonexistent lun 256 will be confused with lun 0,
because the lun member in a request message is only u8, and 256
will become 0. So we need to fix the problem, at least, at the

On MTU change, velocity_give_many_rx_descs() is again called before
velocity_init_registers(). I'm not sure whether this is unsafe but

[...]
Here is why.
On suspend:
- PM core starts suspending devices, ucc_geth_suspend gets called;
- ucc_geth calls phy_stop() on suspend. Note that phy_stop() is
mostly asynchronous so it doesn't block ucc_geth's suspend routine,
it just sets PHY_HALTED state and disables PHY's interrupts;
- Suddenly the state machine gets scheduled, it grabs the phydev->lock
mutex and tries to process the PHY_HALTED state, so it calls
phydev->adjust_link(phydev->attached_dev). In ucc_geth case
adjust_link() calls msleep(), which reschedules the code flow back to
PM core, which now finishes suspend and so we end up sleeping with
phydev->lock mutex held.
On resume:
- PM core starts resuming devices (notice that nobody rescheduled
the state machine yet, so the mutex is still held), the core calls
ucc_geth's resume routine;
- ucc_geth_resume restarts the PHY with phy_stop()/phy_start()
sequence, and the phy_*() calls are trying to grab the phydev->lock
mutex. Here comes the deadlock.
This patch fixes the issue by stopping the state machine on suspend
and starting it again on resume.

Today's -tip failed to build because commit
9e368fa011 ("ipmi: add PNP discovery (ACPI

build failure on x86, for CONFIG_ACPI=n && CONFIG_IPMI_SI=y:
drivers/char/ipmi/ipmi_si_intf.c:3208: error: 'ipmi_pnp_driver' undeclared (first use in this function)

drivers/char/ipmi/ipmi_si_intf.c:3334: error: 'ipmi_pnp_driver' undeclared (first use in this function)
The reason is that the ipmi_pnp_driver depends on ACPI facilities and is only
made available under ACPI - while the registration and unregistration is made
dependent on CONFIG_PNP:
#ifdef CONFIG_PNP
pnp_register_driver(&ipmi_pnp_driver);
#endif
The solution is to only register this driver under ACPI. (Also, the CONFIG_PNP
dependency is not needed because pnp_register_driver() is stubbed out in the
!CONFIG_PNP case.)

If two arrays share a device, then they will not both resync at the
same time. One will wait for the other to complete.
While waiting, the MD_RECOVERY_INTR flag is not checked so a device
failure, which would make the resync pointless, does not cause the
resync to abort, so the failed device cannot be removed (as it cannot
be remove while a resync is happening).
So add a test for MD_RECOVERY_INTR.

By default md_do_sync() will perform recovery if no other actions are

The start_ro modules parameter can be used to force arrays to be
started in 'auto-readonly' in which they are read-only until the first
write. This ensures that no resync/recovery happens until something
else writes to the device. This is important for resume-from-disk
off an md array.
However if an array is started 'readonly' (by writing 'readonly' to
the 'array_state' sysfs attribute) we want it to be really 'readonly',
not 'auto-readonly'.
So strengthen the condition to only set auto-readonly if the
array is not already read-only.

evms configures md arrays by:
open device
send ioctl
close device
for each different ioctl needed.
Since 2.6.29, the device can disappear after the 'close'
unless a significant configuration has happened to the device.
The change made by "SET_ARRAY_INFO" can too minor to stop the device
from disappearing, but important enough that losing the change is bad.
So: make sure SET_ARRAY_INFO sets mddev->ctime, and keep the device
active as long as ctime is non-zero (it gets zeroed with lots of other
things when the array is stopped).
This is suitable for -stable kernels since 2.6.29.

Update the Kconfig help texts of both stacks to encourage a general move
from the older to the newer drivers. However, do not label ieee1394 as
"Obsolete" yet, as the newer drivers have not been deployed as default
stack in the majority of Linux distributions yet, and those who start
doing so now may still want to install the old drivers as fallback for
unforeseen issues.
Since Linux 2.6.32, FireWire audio devices can be driven by the newer
firewire driver stack too, hence remove an outdated comment about audio
devices. Also remove comments about library versions since the 2nd

This is a minimal change meant for the short term: Never set the
ohci->use_dualbuffer flag to true.
There are two reasons to do so:
- Packet-per-buffer mode and dual-buffer mode do not behave the same
under certain circumstances, notably if several packets are covered
by a single fw_cdev_iso_packet descriptor.
http://marc.info/?l=linux1394-devel&m=124965653718313
Therefore the driver stack should not silently choose one or the
other mode but should leave the choice to the high-level driver
(regardless if kernel driver or userspace driver). Or simply always
only offer packet-per-buffer mode, since a considerable number of
controllers, even current ones, does not offer dual-buffer support.
- Even under circumstances where packet-per-buffer mode and
dual-buffer mode behave exactly the same --- notably when used
through libraw1394, libdc1394, as well as the current two kernel
drivers which use isochronous reception (firewire-net and firedtv)
--- we are still faced with the problem that several OHCI 1.1
controllers have bugs in dual-buffer mode. Although it looks like
we have identified most of those buggy controllers by now, we
cannot be quite sure about that.
So, use packet-per-buffer by default from now on. This change should
be followed up by a more complete solution: Either extend the
in-kernel API and the userspace ABI by a choice between the two IR modes
or remove all dual-buffer related code from firewire-ohci.

Control of more than one AV/C device at once --- e.g. camcorders, tape
decks, audio devices, TV tuners --- failed or worked only unreliably,
depending on driver implementation. This affected kernelspace and
userspace drivers alike and was caused by firewire-core's inability to
accept multiple registrations of FCP listeners.
The fix allows multiple address handlers to be registered for the FCP
command and response registers. When a request for these registers is
received, all handlers are invoked, and the Firewire response is
generated by the core and not by any handler.
The cdev API does not change, i.e., userspace is still expected to send
a response for FCP requests; this response is silently ignored.

The calibration period is now invoked by triggering a software
interrupt from within the ISR by ath5k_hw_calibration_poll()
instead of via a timer.
However, the calibration interval isn't initialized before
interrupts are enabled, so we can have a situation where an
interrupt occurs before the interval is assigned, so the
interval is actually negative. As a result, the ISR will
arm a software interrupt to schedule the tasklet, and then
rearm it when the SWI is processed, and so on, leading to a
softlockup at modprobe time.
Move the initialization order around so the calibration interval
is set before interrupts are active. Another possible fix
is to schedule the tasklet directly from the poll routine,
but I think there are additional plans for the SWI.

The gfar_select_queue() function was used to set queue mapping
only for forwarding/bridging applications and the condition
for locally generated packets was completely ignored.
The solution is to remove the gfar_select_queue() function and
use skb_record_rx_queue to set queue mapping for
forwarding/bridging applications. This will ensure that in case of
forwarding/bridging applications txq = rxq will be selected and
skb_tx_hash will be used to pick up a txq for locally generated packets.

This is because ucc_geth_tx() tries to process an empty queue when
queues are logically stopped. Stopping the queues doesn't disable
polling, and since nowadays ucc_geth_tx() is actually called from
the polling routine, the oops above might pop up.
Fix this by removing 'netif_queue_stopped() == 0' check.

This not only saves some memory, but also allows the thinkpad-acpi

control interface is not wanted.
This change fixes a build problem that is causing some annoyances, in

However, in September 2008 commit 898b054f3e
("dock: make dock driver not a module") removed the possibility of having
CONFIG_ACPI_DOCK=m and therefore there is no need for selecting it when
CONFIG_ATA_ACPI=y.
This makes the kernel ~5 Kb smaller for people who don't have a dock by
