Bob Copeland bdc71bc592 ath5k: fix error handling in ath5k_beacon_send
This cleans up error handling for the beacon in case of dma mapping
failure.  We need to free the skb when dma mapping fails instead of
nulling and leaking the pointer, and we should bail out to avoid
giving the hardware the bad descriptor.

Finally, we need to perform the null check after trying to update
the beacon, or else beacons will never be sent after a single
mapping failure.

Christoph Lameter 81107188f1 slub: Fix partial count comparison confusion
deactivate_slab() has the comparison if more than the minimum number of
partial pages are in the partial list wrong. An effect of this may be that
empty pages are not freed from deactivate_slab(). The result could be an
OOM due to growth of the partial slabs per node. Frees mostly occur from
__slab_free which is okay so this would only affect use cases where a lot
of switching around of per cpu slabs occur.

Switching per cpu slabs occurs with high frequency if debugging options are
enabled.

Akinobu Mita ef62fb32b7 slub: fix check_bytes() for slub debugging
The check_bytes() function is used by slub debugging.  It returns a pointer
to the first unmatching byte for a character in the given memory area.

If the character for matching byte is greater than 0x80, check_bytes()
doesn't work.  Becuase 64-bit pattern is generated as below.

	value64 = value | value << 8 | value << 16 | value << 24;
	value64 = value64 | value64 << 32;

The integer promotions are performed and sign-extended as the type of value
is u8.  The upper 32 bits of value64 is 0xffffffff in the first line, and
the second line has no effect.

This fixes the 64-bit pattern generation.

Dave Martin 2102a65e69 ARM: 7008/1: alignment: Make SIGBUS sent to userspace POSIXly correct
With the UM_SIGNAL alignment fault mode, no siginfo structure is

POSIX specifies how siginfo_t should be populated for alignment
faults, so this patch does just that:

  * si_signo = SIGBUS
  * si_code = BUS_ADRALN
  * si_addr = misaligned data address at which access was attempted

Dave Martin 088c01f1e3 ARM: 7007/1: alignment: Prevent ignoring of faults with ARMv6 unaligned access model
Currently, it's possible to set the kernel to ignore alignment
faults when changing the alignment fault handling mode at runtime
via /proc/sys/alignment, even though this is undesirable on ARMv6
and above, where it can result in infinite spins where an un-fixed-
up instruction repeatedly faults.

In addition, the kernel clobbers any alignment mode specified on
the command-line if running on ARMv6 or above.

This patch factors out the necessary safety check into a couple of
new helper functions, and checks and modifies the fault handling
mode as appropriate on boot and on writes to /proc/cpu/alignment.

Prior to ARMv6, the behaviour is unchanged.

For ARMv6 and above, the behaviour changes as follows:

  * Attempting to ignore faults on ARMv6 results in the mode being
    forced to UM_FIXUP instead.  A warning is printed if this
    happened as a result of a write to /proc/cpu/alignment.  The
    user's UM_WARN bit (if present) is still honoured.

  * An alignment= argument from the kernel command-line is now
    honoured, except that the kernel will modify the specified mode
    as described above.  This is allows modes such as UM_SIGNAL and
    UM_WARN to be active immediately from boot, which is useful for
    debugging purposes.

Without this, request_irq on subsequent device initialization fails, and
the codec cannot be used.

Stephen Warren 29591ed4ac ASoC: Tegra: wm8903 machine driver: Allow re-insertion of module
Two issues were preventing module snd-soc-tegra-wm8903.ko from being
removed and re-inserted:

a) The speaker-enable GPIO is hosted by the WM8903 chip. This GPIO must
   be freed before snd_soc_unregister_card() is called, because that
   triggers wm8903.c:wm8903_remove(), which calls gpiochip_remove(), which
   then fails if any of the GPIOs are in use. To solve this, free all GPIOs
   first, so the code doesn't care where they come from.

b) We need to call snd_soc_jack_free_gpios() to match the call to
   snd_soc_jack_add_gpios() during initialization. Without this, the
   call to snd_soc_jack_add_gpios() fails during any subsequent modprobe
   and initialization, since the GPIO and IRQ are already registered. In
   turn, this causes the headphone state not to be monitored, so the
   headphone is assumed not to be plugged in, and the audio path to it is
   never enabled.

Stephen Warren a96edd59b2 ASoC: Tegra: tegra_pcm_deallocate_dma_buffer: Don't OOPS
Not all PCM devices have all sub-streams. Specifically, the SPDIF driver
only supports playback and hence has no capture substream. Check whether
a substream exists before dereferencing it, when de-allocating DMA
buffers in tegra_pcm_deallocate_dma_buffer.

Arnaud Lacombe a7e6401e19 usb/host/pci-quirks.c: correct annotation of `ehci_dmi_nohandoff_table'
ehci_bios_handoff() is marked __devinit, `ehci_dmi_nohandoff_table' should be
marked __devinitconst, not __initconst. This fixes the following section
mismatch:

WARNING: vmlinux.o(.devinit.text+0x4f08): Section mismatch in reference from the function ehci_bios_handoff() to the variable .init.rodata:ehci_dmi_nohandoff_table
The function __devinit ehci_bios_handoff() references a variable __initconst ehci_dmi_nohandoff_table.
If ehci_dmi_nohandoff_table is only used by ehci_bios_handoff then annotate ehci_dmi_nohandoff_table with a matching annotation.

This patch adds the product ID of Huawei's Vodafone K4511 mobile broadband
modem to option.c. This is necessary so that the driver gets loaded on demand
without the intervention of usb_modeswitch. This has the benefit of it becoming

Uwe Bonnes 0ee404ccf1 usb: serial: ftdi_sio.c: For the FT232H FTDI_SIO_SET_BAUDRATE_REQUEST, index needs to be shifted too
the recent addition of the FT232H showed that baudrate was set wrong. See
gmane.linux.usb.general: "[ftdi_sio] FT232H support".  With the old code,
the MSB of the 4 encoded fractional divider bits and more important the
clock predivider bits got lost. Adding the FT232H to the code patch were
these bits are shifted solves the problem. I verified baud rates with a
scope now.

I suspect, that the BM device probably needs these bits shifted too. But
there is no predivider bit, so this is not obvious, and a missing MSB of the
encoded fractional divider only shifts the resulting baudrate minimal.
The AM has only 3 bits of encoded fractional divider, so it is not impacted.

I have no BM device to test, so I only added a comment and left the code for
the BM untouched.
