After cancelling all reads from the disable hook, we need to reset the

Linux' notion of cpuid is different from the Host's notion of CPUID. In the
call to bind the channel interrupts, we should use the host's notion of
CPU Ids. Fix this bug.

John W. Linville says:
====================
This pull request is intended for the 3.10 series. It contains a
variety of fixes for problems discovered during the merge window and
after 3.10-rc1.
For the mac80211 bits, Johannes says the following:
"This is what I have:
* a patch from Felix to fix RCU usage in his rate table code
* a patch from Ilan to add the wdev id to some notifications so they can
actually be used by userspace
* Sasha Levin found an issue in how hwsim handles devices
* a fix for a bug in the wiphy_register() error path that's been there forever
* three fixes for WoWLAN
* AP mode frame matching was erroneously giving frames to all virtual AP
interfaces (reported by Jouni)
* a fix for HT handling in my CSA changes, found by Sujith
* a fix for some locking simplifications gone wrong
* Ben Greear found more cfg80211/mac80211 state confusion
* and a fix for another bug found by Jouni: local state changes need to be
reported by mac80211 to cfg80211 so it disconnects properly."
And for the iwlwifi bits, he says:
"I have fixes for a firmware crash during resume, multicast RX,
aggregation and a workaround for a firmware scanning bug."
Along with those...
Albert Pool adds a USB ID to the rtl8192cu driver.
Arend van Spriel restores a driver option support flag that had been
removed from 3.9 due to a bug in that version of the driver.
Felix Fietkau fixes a trio of ath9k issues with a series of small
patches.
Geert Uytterhoeven provides a Kconfig fix for ath9k (which you also
merged, so it isn't in the diff here).
Larry Finger gives us a fix for a build warning on big-endian systems
for rtlwifi.
Rafał Miłecki adds some core IDs to the bcma driver.
Sujith Manoharan fixes a module unloading crash in ath9k, and corrects
some calibration settings for AR9485.

I meet emacs hang in start if I do the operation below:
1: echo 3 > /proc/sys/vm/drop_caches
2: emacs BigFile
3: Press CTRL-S follow 2 immediately
Then emacs hang on, CTRL-Q can't resume, the terminal
hang on, you can do nothing with this terminal except
close it.
The reason is before emacs takeover control the tty,
we use CTRL-S to XOFF it. Then when emacs takeover the
control, it may don't use the flow-control, so emacs hang.
This patch fix it.
This patch will fix a kind of strange tty relation hang problem,

Now that the tty port owns the flip buffers and i/o is allowed
from the driver even when no tty is attached, the destruction
of the tty port (and the flip buffers) must ensure that no
outstanding work is pending.
Unfortunately, this creates a lock order problem with the
console_lock (see attached lockdep report [1] below).
For single console deallocation, drop the console_lock prior
to port destruction. When multiple console deallocation,
defer port destruction until the consoles have been
deallocated.
tty_port_destroy() is not required if the port has not
been used; remove from vc_allocate() failure path.

Commit ffc3ae6dd "serial: 8250_dw: Enable runtime PM" introduced runtime
PM management, which enables/disables the clk without checking if the clk
is valid. However, this driver allows to be probed without a defined clk,
using clock-frequency, as a fallback.
Therefore, on platforms that are device tree probed using clock-frequency
instead of clk, we get an ugly NULL pointer dereference.
This patch fixes it by simply adding a check before accessing the clk api.

The current driver doesn't use the set and clear registers found on the
mxs gpio controller.
This leads the generic gpio controller to be using some internal value
to avoid looking up the value stored in the registers, making it behave
pretty much like a cache.
This raises some coherency problem when a gpio is not modified by the
gpio controller, while it can easily be fixed by using the set and clear
registers.

When DT is not used IOAPIC does not register irq domain. As result
IOAPIC won't care about gpio-langwell's virq and may cause conflict if
an irq number is equal to gpio-langwell's virq mapped beforehand.
This patch tells gpio_langwell to not ignore irq_base if != 0 and
preferably use it to avoid the conflict.
If DT is used, irq_base can safely be 0.

When CONFIG_I2C=m, meaning we can't build the drivers in with I2C support.
Thus don't allow the drivers to be compiled as built-in when CONFIG_I2C=m.
The real fix though is to break the driver apart into a SPI part, an I2C part
and a common part. But that's something for 3.11 while this is something for
3.10/stable.

Starting with commit 91226790bbe2dbfbba48dd79d49f2b38ef10eb97
`bnx2x: use FW 7.8.17', the bnx2x driver no longer requests the FW to perform
IP checksums for IPv4 packets.
This behaviour needs to be revised for 57710/57711 chips -
when using GSO, if the driver will not set the IP checksum flag then packets
will be transmitted by the chip without a valid IP checksum, resulting in
a drop of all such packets on the receiver-side.

8168evl offloaded checksums are wrong since commit
e5195c1f31f399289347e043d6abf3ffa80f0005 ("r8169: fix 8168evl frame padding.")
pads small packets to 60 bytes (without ethernet checksum). Typical symptoms
appear as UDP checksums which are wrong by the count of added bytes.
It isn't worth compensating. Let the driver checksum.
Due to the skb length changes, TSO code is moved before the Tx descriptor gets
written.

When bond_3ad_get_active_agg_info() is used in all show_ad_ functions
it is not protected against slave manipulation and since it walks over
the slaves and uses them, this can easily result in NULL pointer
dereference or use of freed memory. Both the new wrapper and the
internal function are exported to the bonding as they're needed in
different places.
