The link may be up already via the chip's reset strapping, or though action
of U-Boot, or from the last time the interface was brought up. Resetting
the link causes it to go down for several seconds. This can significantly
increase the time from power-on to DHCP completion and a device being
accessible to the network.

The init_phy() function attaches to the PHY, then configures the
SerDes<->TBI link (in SGMII mode). The TBI is on the MDIO bus with the PHY
(sort of) and is accessed via the gianfar's MDIO registers, using the
functions gfar_local_mdio_read/write(), which don't do any locking.
The previously attached PHY will start a work-queue on a timer, and
probably an irq handler as well, which will talk to the PHY and thus use
the MDIO bus. This uses phy_read/write(), which have locking, but not
against the gfar_local_mdio versions.
The result is that PHY code will try to use the MDIO bus at the same time
as the SerDes setup code, corrupting the transfers.
Setting up the SerDes before attaching to the PHY will insure that there is
no race between the SerDes code and *our* PHY, but doesn't fix everything.
Typically the PHYs for all gianfar devices are on the same MDIO bus, which
is associated with the first gianfar device. This means that the first
gianfar's SerDes code could corrupt the MDIO transfers for a different
gianfar's PHY.
The lock used by phy_read/write() is contained in the mii_bus structure,
which is pointed to by the PHY. This is difficult to access from the
gianfar drivers, as there is no link between a gianfar device and the
mii_bus which shares the same MDIO registers. As far as the device layer
and drivers are concerned they are two unrelated devices (which happen to
share registers).
Generally all gianfar devices' PHYs will be on the bus associated with the
first gianfar. But this might not be the case, so simply locking the
gianfar's PHY's mii bus might not lock the mii bus that the SerDes setup
code is going to use.
We solve this by having the code that creates the gianfar platform device
look in the device tree for an mdio device that shares the gianfar's
registers. If one is found the ID of its platform device is saved in the
gianfar's platform data.
A new function in the gianfar mii code, gfar_get_miibus(), can use the bus
ID to search through the platform devices for a gianfar_mdio device with
the right ID. The platform device's driver data is the mii_bus structure,
which the SerDes setup code can use to lock the current bus.

A panic was discovered with bonding when using mode 5 or 6 and trying to
remove the slaves from the bond after the interface was taken down.
When calling 'ifconfig bond0 down' the following happens:
bond_close()
bond_alb_deinitialize()
tlb_deinitialize()
kfree(bond_info->tx_hashtbl)
bond_info->tx_hashtbl = NULL
Unfortunately if there are still slaves in the bond, when removing the
module the following happens:
bonding_exit()
bond_free_all()
bond_release_all()
bond_alb_deinit_slave()
tlb_clear_slave()
tx_hash_table = BOND_ALB_INFO(bond).tx_hashtbl
u32 next_index = tx_hash_table[index].next
As you might guess we panic when trying to access a few entries into the
table that no longer exists.
I experimented with several options (like moving the calls to
tlb_deinitialize somewhere else), but it really makes the most sense to
be part of the bond_close routine. It also didn't seem logical move
tlb_clear_slave around too much, so the simplest option seems to add a
check in tlb_clear_slave to make sure we haven't already wiped the
tx_hashtbl away before searching for all the non-existent hash-table
entries that used to point to the slave as the output interface.

If there are several snapshots sharing an origin and one is removed
while the origin is being written to, the snapshot's mempool may get
deleted while elements are still referenced.
Prior to dm-snapshot-use-per-device-mempools.patch the pending
exceptions may still have been referenced after the snapshot was
destroyed, but this was not a problem because the shared mempool
was still there.
This patch fixes the problem by tracking the number of mempool elements
in use.
The scenario:
- You have an origin and two snapshots 1 and 2.
- Someone writes to the origin.
- It creates two exceptions in the snapshots, snapshot 1 will be primary
exception, snapshot 2's pending_exception->primary_pe will point to the
exception in snapshot 1.
- The exceptions are being relocated, relocation of exception 1 finishes
(but it's pending_exception is still allocated, because it is referenced
by an exception from snapshot 2)
- The user lvremoves snapshot 1 --- it calls just suspend (does nothing)
and destructor. md->pending is zero (there is no I/O submitted to the
snapshot by md layer), so it won't help us.
- The destructor waits for kcopyd jobs to finish on snapshot 1 --- but
there are none.
- The destructor on snapshot 1 cleans up everything.
- The relocation of exception on snapshot 2 finishes, it drops reference
on primary_pe. This frees its primary_pe pointer. Primary_pe points to
pending exception created for snapshot 1. So it frees memory into
non-existing mempool.

This patch (as1153) fixes a potential problem in hub initialization.
Starting in 2.6.28, initialization was split into several tasks to
help speed up booting. This opens the possibility that the hub may be
autosuspended before all the initialization tasks can complete.
Normally that wouldn't matter, but with incomplete initialization
there is a risk that the hub would never autoresume -- especially if
devices were plugged into the hub beforehand. The solution is a
simple one-line change to suppress autosuspend until the
initialization is finished.

This patch (as1151) protects usbcore against drivers that try to
unlink an URB after the URB's device or bus have been removed. The
core does not currently check for this, and certain drivers can cause
a crash if they are running while an HCD is unloaded.
Certainly it would be best to fix the guilty drivers. But a little
defensive programming doesn't hurt, especially since it appears that
quite a few drivers need to be fixed.
The patch prevents the problem by grabbing a reference to the device
while an unlink is in progress and using a new spinlock to synchronize
unlinks with device removal. (There's no need to acquire a reference
to the bus as well, since the device structure itself keeps a
reference to the bus.) In addition, the kerneldoc is updated to
indicate that URBs should not be unlinked after the disconnect method
returns.

Take care to handle register 0xa228 exactly as in the HAL released by
Atheros. This change is required to make ath5k work again on my system
since commit 2203d6be (ath5k: Misc hw_reset updates), thus fixing a
regression in 2.6.27 and therefore hopefully eligible for inclusion into
a stable release.
v2: Only overwrite initial register values on later revisions of AR5212
chips.
v3: Use standard macros to manipulate the register.

If somebody sends an invalid beacon/probe response, that can trash the

The iscsi_ibft.c changes are almost certainly a bugfix as the
pointer 'ip' is a u8 *, so they never print the last 8 bytes
of the IPv6 address, and the eight bytes they do print have
a zero byte with them in each 16-bit word.

md arrays are not currently destroyed when they are stopped - they
remain in /sys/block. Last time I tried this I tripped over locking
too much.
A consequence of this is that udev doesn't remove anything from /dev.
This is rather ugly.
As an interim measure until proper device removal can be achieved,
make sure all partitions are removed using the BLKRRPART ioctl, and
send a KOBJ_CHANGE when an md array is stopped.

Add an appropriate entry for the Promise PDC42819 controller. It has an
AHCI mode and so far works correctly with board_ahci.
This chip is found on Promise's FastTrak TX2650 (2 port) and TX4650 (4 port)
software-based RAID cards (for which there is a binary driver, t3sas) and
can be found on some motherboards, for example the MSI K9A2 Platinum,
which calls the chip a Promise T3 controller.
Although this controller also supports SAS devices, its default bootup mode
is AHCI and the binary driver has to do some magic to get the chip into the
appropriate mode to drive SAS disks.
Seeing as no documentation is provided by Promise, adding this entry to the
ahci driver allows the controller to be useful to people as a SATA
controller (with no ill effects on the system if a SAS disk is connected -
probing of the port just times out with "link online but device
misclassified"), without having to resort to using the binary driver. Users
who require SAS or the proprietary software raid can get this functionality
using the binary driver.

The LM99 differs from the LM86, LM89 and LM90 in that it reports
remote temperatures (temp2) 16 degrees lower than they really are. So
far we have been cheating and handled this in userspace but it really
should be handled by the driver directly.
Signed-off-by: Jean Delvare <khali@linux-fr.org>
Cc: Matthew Garrett <mjg59@srcf.ucam.org>
There are several problems in the way the hysteresis value is handled
by the lm90 driver:
* In show_temphyst(), specific handling of the MAX6646 is missing, so
the hysteresis is reported incorrectly if the critical temperature
is over 127 degrees C.
* In set_temphyst(), the new hysteresis register value is written to
the chip but data->temp_hyst isn't updated accordingly, so there is
a short period of time (up to 2 seconds) where the old hystereris
value will be returned while the new one is already active.
* In set_temphyst(), the critical temperature which is used as a base
to compute the value of the hysteresis register lacks
device-specific handling. As a result, the value of the hysteresis
register might be incorrect for the ADT7461 and MAX6646 chips.
Fix these 3 bugs.
