We should disable irqs when we take the tu->qlock because it is used in the irq handler. The only place that doesn't is snd_timer_user_ccallback(). Most of the time snd_timer_user_ccallback() is called with interrupts disabled but the the first ti->ccallback() call in snd_timer_notify1() has interrupts enabled.

-
David Howells authored
key_gc_keyring() needs to either hold the RCU read lock or hold the keyring semaphore if it's going to scan the keyring's list. Given that it only needs to read the key list, and it's doing so under a spinlock, the RCU read lock is the thing to use. Furthermore, the RCU check added in e7b0a61b is incorrect as holding the spinlock on key_serial_lock is not grounds for assuming a keyring's pointer list can be read safely. Instead, a simple rcu_dereference() inside of the previously mentioned RCU read lock is what we want. Reported-by:

Some FSC hardware monitoring chips (Syleus at least) doesn't like quick writes we typically use to probe for I2C chips. Use a regular byte read instead for the address they live at (0x73). These are the only known chips living at this address on PC systems. For clarity, this fix should not be needed for kernels 2.6.30 and later, as we started instantiating the hwmon devices explicitly based on DMI data. Still, this fix is valuable in the following two cases: * Support for recent FSC chips on older kernels. The DMI-based device instantiation is more difficult to backport than the device support itself. * Case where the DMI-based device instantiation fails, whatever the reason. We fall back to probing in that case, so it should work. This fixes kernel bug #15634: https://bugzilla.kernel.org/show_bug.cgi?id=15634 Signed-off-by:

Receiving small packet(s) in a fast pace leads to not receiving any packets at all after some time. After ethernet packet(s) arrived the receive descriptor is incremented by the number of frames processed. If another packet arrives while processing, this is processed in another call of ep93xx_rx. This second call leads that too many receive descriptors getting released. This fix increments, even in these case, the right number of processed receive descriptors. Signed-off-by:

Use correct bit positions in DM_SHARED_CTRL register for writes. Michael Planes recently encountered a 'KY-RS9600 USB-LAN converter', which came with a driver CD containing a Linux driver. This driver turns out to be a copy of dm9601.c with symbols renamed and my copyright stripped. That aside, it did contain 1 functional change in dm_write_shared_word(), and after checking the datasheet the original value was indeed wrong (read versus write bits). On Michaels HW, this change bumps receive speed from ~30KB/s to ~900KB/s. On other devices the difference is less spectacular, but still significant (~30%). Reported-by:

In ppp_input(), PPP_PROTO(skb) may refer to invalid data in the skb. If this happens and (proto >= 0xc000 || proto == PPP_CCPFRAG) then the packet is passed directly to pppd. This occurs frequently when using PPPoE with an interface MTU greater than 1500 because the skb is more likely to be non-linear. The next 2 bytes need to be pulled in ppp_input(). The pull of 2 bytes in ppp_receive_frame() has been removed as it is no longer required. Signed-off-by:
