e6af578c53 virtio-pci: make reset operation safer
virtio pci device reset actually just does an I/O
write, which in PCI is really posted, that is it
can complete on CPU before the device has received it.

Further, interrupts might have been pending on
another CPU, so device callback might get invoked after reset.

This conflicts with how drivers use reset, which is typically:
	reset
	unregister
a callback running after reset completed can race with
unregister, potentially leading to use after free bugs.

Fix by flushing out the write, and flushing pending interrupts.

This assumes that device is never reset from
its vq/config callbacks, or in parallel with being
added/removed, document this assumption.

cc1b0765da ARM: OMAP: hwmod: Fix the addr space, irq, dma count APIs
The address spaces, irqs and dma reqs count APIs return the
number of corresponding entries in a hwmod including a additional
null value or a -1 terminator in the structure introduced recently.
More information here:

- 212738a4: omap_hwmod: use a terminator record with omap_hwmod_mpu_irqs
  arrays

- 78183f3f: omap_hwmod: use a null structure record to terminate
  omap_hwmod_addr_space arrays

- bc614958: omap_hwmod: use a terminator record with omap_hwmod_dma_info
  arrays

The issue with irqs and dma info was originally reported by Benoit Cousson.

The devices which have multiple hwmods and use device_build_ss are
broken with this, as their resources are populated with a extra null
value, subsequently the probe fails. So fix the API not to include
the array terminator in the count.

0f751e641a eCryptfs: Extend array bounds for all filename chars
From mhalcrow's original commit message:

    Characters with ASCII values greater than the size of
    filename_rev_map[] are valid filename characters.
    ecryptfs_decode_from_filename() will access kernel memory beyond
    that array, and ecryptfs_parse_tag_70_packet() will then decrypt
    those characters. The attacker, using the FNEK of the crafted file,
    can then re-encrypt the characters to reveal the kernel memory past
    the end of the filename_rev_map[] array. I expect low security
    impact since this array is statically allocated in the text area,
    and the amount of memory past the array that is accessible is
    limited by the largest possible ASCII filename character.

This patch solves the issue reported by mhalcrow but with an
implementation suggested by Linus to simply extend the length of
filename_rev_map[] to 256. Characters greater than 0x7A are mapped to
0x00, which is how invalid characters less than 0x7A were previously
being handled.

Dirty pages weren't being written back when an mmap'ed eCryptfs file was

b59db43ad4 eCryptfs: Prevent file create race condition
The file creation path prematurely called d_instantiate() and
unlock_new_inode() before the eCryptfs inode info was fully
allocated and initialized and before the eCryptfs metadata was written
to the lower file.

This could result in race conditions in subsequent file and inode
operations leading to unexpected error conditions or a null pointer
dereference while attempting to use the unallocated memory.

Count of selector voltage is required for regulator_set_voltage

so regulator_set_voltage won't work for VDD1/2.
Update count (n_voltages) for VDD1/2.

Output Voltage = (step value * 12.5 mV + 562.5 mV) * gain

With above expr, number of voltages that can be selected is
step value count * gain count

constant for gain count will be called VDD1_2_NUM_VOLT_COARSE

existing constant for step value count is VDD1_2_NUM_VOLTS,
use VDD1_2_NUM_VOLT_FINE instead to make clear that step value
is not the only component in deciding selectable voltage count

When the imux entries are rebuilt in alc_rebuild_imux_for_auto_mic(),
the initialization of index field is missing.  It may work without it
casually when the original imux was created by the auto-parser, but
it's definitely broken in the case of static configs where no imux was

work properly on some model options.

6dfeb703e3 ALSA: hda - Fix invalid pin and GPIO for Apple laptops with CS codecs
The PCI SSID 8086:7270 is commonly used for multiple Apple machines,
thus we can't use it as identifier for a unique model.  Because of this
conflict, some machines show weird behavior.  For example, MacBook Air
shows Front and Surround speakers although only Surround works due to
the wrongly overridden pin-configuration for imac27.

This patch fixes two things:
- Stop the wrong pin-config override of imac27 by removing PCI SSID
  entry for avoiding the wrong mappings,
- Add the generic GPIO setup for Apple machines by checking the codec
  SSID vendor bits

b4bbb02934 Revert "of/irq: of_irq_find_parent: check for parent equal to child"
This reverts commit dc93728084.

As requested by Ben Herrenschmidt:
  "This breaks some powerpc platforms at least.  The practice of having
   a node provide an explicit "interrupt-parent" property pointing to
   itself is an old trick that we've used in the past to allow a
   device-node to have interrupts routed to different controllers.

   In that case, the node also contains an interrupt-map, so the node is
   its own parent, the interrupt resolution hits the map, which then can
   route each individual interrupt to a different parent."

Grant says:
  "Ah, nuts, yes that is broken then.  Yes, please revert the commit and
   Rob & I will come up with a better solution.

   Rob, I think it can be done by explicitly checking for np ==
   desc->interrupt_parent in of_irq_init() instead of relying on
   of_irq_find_parent() returning NULL."

24ca9a8477 SUNRPC: Ensure we return EAGAIN in xs_nospace if congestion is cleared
By returning '0' instead of 'EAGAIN' when the tests in xs_nospace() fail
to find evidence of socket congestion, we are making the RPC engine believe
that the message was incorrectly sent and so it disconnects the socket
instead of just retrying.

The bug appears to have been introduced by commit
5e3771ce2d (SUNRPC: Ensure that xs_nospace
return values are propagated).

c916874d60 drivers/gpu/vga/vgaarb.c: add missing kfree
kbuf is a buffer that is local to this function, so all of the error paths
leaving the function should release it.

21240f9bc1 drm/radeon/kms/atom: unify i2c gpio table handling
Split the quirks and i2c_rec assignment into separate
functions used by both radeon_lookup_i2c_gpio() and
radeon_atombios_i2c_init().  This avoids duplicating code
and cases where quirks were only added to one of the
functions.

d724502a9d drm/radeon/kms: fix up gpio i2c mask bits for r4xx for real
Fixes i2c test failures when i2c_algo_bit.bit_test=1.

The hw doesn't actually require a mask, so just set it
to the default mask bits for r1xx-r4xx radeon ddc.

I missed this part the first time through.

e5a2132764 ARM: perf: check that we have a platform device when reserving PMU
Attempting to use a hardware counter on a platform with a supported PMU
but where the platform_device (defining the interrupts) has not been
registered results in a NULL pointer dereference.

This patch fixes the problem by checking that we actually have a platform
device registered before attempting to grab the interrupts.
