90d8dabf74 drivers/misc: Move misplaced pci_dev_put's
Move pci_dev_put outside the loops in which it occurs.  Within the loop,
pci_dev_put is done implicitly by pci_get_device.

The problem was detected using the following semantic patch, and corrected
by hand.

@@
expression dev;
expression E;
@@

- pci_dev_put(dev)
   ... when != dev = E
- pci_get_device(...,dev)

e62aa046e1 paride: pf driver fixes
The pf driver for parallel port floppy drives seems to be broken.  At least
with Imation SuperDisk with EPAT chip, the driver calls pi_connect() and
pi_disconnect after each transferred sector.  At least with EPAT, this
operation is very expensive - causes drive recalibration.  Thus, transferring
even a single byte (dd if=/dev/pf0 of=/dev/null bs=1 count=1) takes 20
seconds, making the driver useless.

The pf_next_buf() function seems to be broken as it returns 1 always (except
when pf_run is non-zero), causing the loop in do_pf_read_drq (and
do_pf_write_drq) to be executed only once.

The following patch fixes this problem.  It also fixes swapped descriptions in
pf_lock() function and removes DBMSG macro, which seems useless.

a4b1d50e61 RTCs: handle NVRAM better
Several of the RTC drivers are exporting binary "nvram" files in sysfs.  Such
NVRAM (or on many systems, EEPROM) data is often initialized during system
manufacture to hold data about identity (serial numbers, Ethernet addresses,
etc), configuration, calibration, and so forth.

This patch improves integrity and security of those files:

  - Correctly initializes the size in one of the two cases where
    that was not yet being done.

  - Improves system security/integrity by making this state not
    be world-writable by default.

Letting arbitrary userspace code mangle such state by default is at least Not
A Good Thing; and it could sometimes be worse, depending on the particular
data that might be corrupted.  (I disregard the paranoiac "don't let anyone
read it either" approach.  Anyone storing passwords in such memory doesn't
really care about security.)

779d20892f rtc_hctosys expects RTCs in UTC (doc)
The RTC "hctosys" mechanism expects that RTC clock will use UTC, not local
time (e.g.  PST).  Say so in Kconfig and in the kernel message.

(Strictly speaking, the RTC clock should be tracking the POSIX epoch.  That's
not worth going into here.  Goofing timezones means clocks are wrong by many
hours; the POSIX-v-UTC differences just cost seconds.)

since for rt2500usb and rt73usb different registers
should be read. When rt2500usb was loaded for a rt73
device it would false think the chipset was correct
because the wrong register was read and validated.

This has been fixed by expanding the check to also
see if the first 4 bits of the revision is not-0
(When reading the wrong register offset the returned
value is usually 0 which can be interpreted as invalid)

9a7666494b RDMA/cxgb3: Set the max_qp_init_rd_atom attribute in query_device
The device attribute max_qp_init_rd_atom is not getting set in cxgb3's
query_device method.  Version 1.0.4 of librdmacm now validates the
user's requested initiator and responder resources against the max
supported by the device.  Since iw_cxgb3 wasn't setting this attribute
(and it defaulted to 0), all rdma_connect()s fail if there are
initiator resources requested by the app.  Fix this by setting the
correct value in iwch_query_device().

c88864df27 [TG3]: Fix 5761 PXEboot crash
When 5761 devices boot the machine using PXEboot, PXE leaves the device
active when it terminates.  The tg3 driver has code to detect this
condition and resets the device during initialization.  On 5761 devices,
device resets involve sending a driver state update message to the APE
on the 5761.  However, during this initialization stage, communications
to the APE registers have not yet been set up.  The driver then
dereferences a NULL pointer and crashes the machine.  The fix is to move
the APE register access setup earlier in the initialization code to
cover this condition.

62768e28d6 [SUNGEM]: Fix suspend regression due to NAPI changes.
Commit bea3348e (the NAPI changes) made sungem unconditionally enable
NAPI when resuming and unconditionally disable when suspending, this,
however, makes napi_disable() hang when suspending when the interface
was taken down before suspend because taking the interface down also
disables NAPI. This patch makes touching the napi struct in
suspend/resume code paths depend on having the interface up, thereby
fixing the hang on suspend.

The patch also moves the napi_disable() in gem_close() under the lock so
that the NAPI state is always modified atomically together with the
"opened" variable.

42b36cc0ce virtio: Force use of power-of-two for descriptor ring sizes
The virtio descriptor rings of size N-1 were nicely set up to be
aligned to an N-byte boundary.  But as Anthony Liguori points out, the
free-running indices used by virtio require that the sizes be a power
of 2, otherwise we get problems on wrap (demonstrated with lguest).

So we replace the clever "2^n-1" scheme with a simple "align to page
boundary" scheme: this means that all virtio rings take at least two
pages, but it's safer than guessing cache alignment.

1bc4953ed4 virtio: Fix used_idx wrap-around
The more_used() function compares the vq->vring.used->idx with last_used_idx.
Since vq->vring.used->idx is a 16-bit integer, and last_used_idx is an
unsigned int, this results in unpredictable behavior when vq->vring.used->idx
wraps around.

This patch corrects this by changing last_used_idx to the correct type.

60d78c4473 ssb: Fix PCMCIA-host lowlevel bus access
This fixes the lowlevel bus access routines for
PCMCIA based devices.

There are still a few issues with register access sideeffects after
this patch. This will be addressed in a later patch.

f51359a8fb iwlwifi: select proper rate control algorithm
Prior to this patch, iwlwifi would always use the first
registered rate control algorithm which, depending on system
setup, could be anything. After the mac80211 patch to make
the simple algorithm built-in, it would always be simple.

This has always been a bug in iwlwifi.

This fixes it by requesting that mac80211 selects the right
rate control algorithm.

a6baf3af89 r8169: prevent bit sign expansion error in mdio_write
Oops.

The current code does not like being given an u16 with the highest
bit set as an argument to mdio_write. Let's enforce a correct range of
values for both the register address and value (resp. 5 and 16 bits).

The callers are currently left as-is.

3e23b7d3b5 qla3xxx: bugfix: Move link state machine into a worker thread
The link state machine requires access to some resources that
are shared with the iSCSI function on the chip.  (See iSCSI
driver at drivers/scsi/qla4xxx)  If the interface is being
up/downed at a rapid pace this driver may need to sleep
waiting to get access to the common resources. For this we
are moving the state machine to run as a work thread.

3a1521b7e5 bonding: don't validate address at device open
The standard validate_addr handler refuses to accept the all zeroes address
as valid.  However, it's common historical practice for the bonding
master to be configured up prior to having any slaves, at which time the
master will have a MAC address of all zeroes.

Resolved by setting the dev->validate_addr to NULL.  The master still can't
end up with an invalid address, as the set_mac_address function tests
for validity.

1466a21997 bonding: fix rtnl locking merge error
Looks like I incorrectly merged one of the rtnl lock changes,
so that one function, bonding_show_active_slave, held rtnl but didn't
release it, and another, bonding_store_active_slave, never held rtnl but
did release it.

	Fixed so the first function doesn't mess with rtnl, and the
second correctly acquires and releases rtnl.

440cb58a7a b43legacy: fix shared IRQ race condition
Fix an IRQ race condition in b43legacy. If we call
b43legacy_wireless_core_stop(), it will set the status of the device to
INITIALIZED and the IRQ handler won't care any longer about IRQs, thus the
kernel will disable the IRQ if it's shared (unless we boot it with the
'irqpoll' option). So we must disable IRQs before changing the device
status.
