Linus Torvalds 0413320900 sound fixes for 3.14-rc4
This time we got a slightly higher volume than previous times,
 but all device-specific good fixes.  Noticeable changes are fixes in
 davinci, and the removal of open-codes in HD-audio ca0132 driver.
 The rest are all small fixes and/or quirks.

Merge tag 'pci-v3.14-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci

Pull PCI updates from Bjorn Helgaas:
 "The most interesting thing here is the change to enable INTx (by
  clearing PCI_COMMAND_INTX_DISABLE) if the BIOS left INTx disabled.
  Apparently the Baytrail BIOS does this, which means EHCI doesn't work.

  Also, fix an AHCI MSI regression and other issues with the recent MSI
  changes.  This also adds pci_enable_msi_exact() and
  pci_enable_msix_exact(), which aren't regression fixes, but will keep
  us from touching drivers twice (once to stop using the deprecated
  pci_enable_msi(), etc., and again to use the *_exact() variants).

  There's also a minor MVEBU fix.

  Summary:

  MSI:
    - Fix AHCI single-MSI fallback (Alexander Gordeev)
    - Fix populate_msi_sysfs() error paths (Greg Kroah-Hartman)

Fix regression caused by commit b072e53, which breaks loading nouveau
driver on optimus laptops.

On some platforms, ACPI _DSM method (nouveau_op_dsm_muid, function 0)
has special requirements on the fourth parameter, which is different
from ACPI specifications. So revert to the private implementation
to check availability of _DSM functions instead of using common
acpi_check_dsm() interface.

Josh Cartwright e7d613d1db usb: phy: msm: fix compilation errors when !CONFIG_PM_SLEEP
Both the PM_RUNTIME and PM_SLEEP callbacks call into the common
msm_otg_{suspend,resume} routines, however these routines are only being
built when CONFIG_PM_SLEEP.  In addition, msm_otg_{suspend,resume} also
depends on msm_hsusb_config_vddcx(), which is only built when
CONFIG_PM_SLEEP.

Fix the CONFIG_PM_RUNTIME, !CONFIG_PM_SLEEP case by changing the
preprocessor conditional, and moving msm_hsusb_config_vddcx().

While we're here, eliminate the CONFIG_PM conditional for setting
up the dev_pm_ops.

This address the following errors Russell King has hit doing randconfig
builds:

drivers/usb/phy/phy-msm-usb.c: In function 'msm_otg_runtime_suspend':
drivers/usb/phy/phy-msm-usb.c:1691:2: error: implicit declaration of function 'msm_otg_suspend'

Andrzej Pietrasiewicz f0f42204d0 usb: gadget: fix NULL pointer dereference
Fix possible NULL pointer dereference introduced in
commit 219580e (usb: f_fs: check quirk to pad epout
buf size when not aligned to maxpacketsize)

In cases we do wait with:

wait_event_interruptible(epfile->wait, (ep = epfile->ep));

for endpoint to be enabled, functionfs_bind() has not been called yet
and epfile->ffs->gadget is still NULL and the automatic variable 'gadget'
has been initialized with NULL at the point of its definition.
Later on it is used as a parameter to:

usb_ep_align_maybe(gadget, ep->ep, len)

which in turn dereferences it.

This patch fixes it by moving the actual assignment to the local 'gadget'
variable after the potential waiting has completed.

Grant Likely 1f42e5dd50 of: Add self test for of_match_node()
Adds a selftest function for the of_match_node function. of_match_node
is supposed to handle precedence for the compatible property as well as
the name and device_type values. This patch adds some test case data and
a function that makes sure each test node matches against the correct
entry of an of_device_id table.

This code was written to verify the new of_match_node() implementation
that is an earlier part of this series.

Grant Likely b5190516b2 of: Move testcase FDT data into drivers/of
The testcase data is usable by any platform. This patch moves it into
the drivers/of directory so it can be included by any architecture.

Using the test cases requires manually adding #include <testcases.dtsi>
to the end of the boards .dtsi file and enabling CONFIG_OF_SELFTEST. Not
pretty though. A useful project would be to make the testcase code
easier to execute.

Kevin Hao 215a14cfac of: reimplement the matching method for __of_match_node()
In the current implementation of __of_match_node(), it will compare
each given match entry against all the node's compatible strings
with of_device_is_compatible().

To achieve multiple compatible strings per node with ordering from
specific to generic, this requires given matches to be ordered from
specific to generic. For most of the drivers this is not true and
also an alphabetical ordering is more sane there.

Therefore, we define a following priority order for the match, and
then scan all the entries to find the best match.
  1. specific compatible && type && name
  2. specific compatible && type
  3. specific compatible && name
  4. specific compatible
  5. general compatible && type && name
  6. general compatible && type
  7. general compatible && name
  8. general compatible
  9. type && name
  10. type
  11. name

v5: Fix nested locking bug
v4: Short-circuit failure cases instead of mucking with score, and
    remove extra __of_device_is_compatible() wrapper stub.
    Move scoring logic directly into __of_device_is_compatible()
v3: Also need to bail out when there does have a compatible member in match
    entry, but it doesn't match with the device node's compatible.
v2: Fix the bug such as we get the same score for the following two match
    entries with the empty node 'name2 { };'
	struct of_device_id matches[] = {
		{.name = "name2", },
		{.name = "name2", .type = "type1", },

Hui Wang 1de7ca5e84 ALSA: hda - Enable front audio jacks on one HP desktop model
The front headphone and mic jackes on a HP desktop model (Vendor Id:
0x111d76c7 Subsystem Id: 0x103c2b17) can not work, the codec on this
machine has 8 physical ports, 6 of them are routed to rear jackes
and all of them work very well, while the remaining 2 ports are
routed to front headphone and mic jackes, but the corresponding
pin complex node are not defined correctly.

After apply this fix, the front audio jackes can work very well.

 fix issues which will prevent correct operation in some use cases and
 only affect that particular driver so are reasonably safe.

Paul Gortmaker a56b072fa3 sparc32: make copy_to/from_user_page() usable from modular code
While copy_to/from_user_page() users are uncommon, there is one in
drivers/staging/lustre/lustre/libcfs/linux/linux-curproc.c which leads
to the following:

ERROR: "sparc32_cachetlb_ops" [drivers/staging/lustre/lustre/libcfs/libcfs.ko] undefined!

during routine allmodconfig build coverage.  The reason this happens
is as follows:

In arch/sparc/include/asm/cacheflush_32.h we have:

 #define flush_cache_page(vma,addr,pfn) \
        sparc32_cachetlb_ops->cache_page(vma, addr)

 #define copy_to_user_page(vma, page, vaddr, dst, src, len) \
        do {                                                    \
                flush_cache_page(vma, vaddr, page_to_pfn(page));\
                memcpy(dst, src, len);                          \
        } while (0)
 #define copy_from_user_page(vma, page, vaddr, dst, src, len) \
        do {                                                    \
                flush_cache_page(vma, vaddr, page_to_pfn(page));\
                memcpy(dst, src, len);                          \
        } while (0)

However, sparc32_cachetlb_ops isn't exported and hence the error.

Paul Gortmaker 4f6500fff5 sparc32: fix build failure for arch_jump_label_transform
In arch/sparc/Kernel/Makefile, we see:

   obj-$(CONFIG_SPARC64)   += jump_label.o

However, the Kconfig selects HAVE_ARCH_JUMP_LABEL unconditionally
for all SPARC.  This in turn leads to the following failure when
doing allmodconfig coverage builds:

kernel/built-in.o: In function `__jump_label_update':
jump_label.c:(.text+0x8560c): undefined reference to `arch_jump_label_transform'
kernel/built-in.o: In function `arch_jump_label_transform_static':
(.text+0x85cf4): undefined reference to `arch_jump_label_transform'
make: *** [vmlinux] Error 1

Change HAVE_ARCH_JUMP_LABEL to be conditional on SPARC64 so that it
matches the Makefile.

Aaron Lu 0e9f81d3b7 ACPI / video: Add systems that should favour native backlight interface
Some system's ACPI video backlight control interface is broken and the
native backlight control interface should be used by default. This patch
sets the use_native_backlight parameter to true for those systems so
that video backlight control interface will not be created. For detailed
models that are added here, reference the following list.

Note that the user specified kernel cmdline option will always have the
highest priority, i.e. if use_native_backlight=0 is specified and the
system is in the DMI table, the video module will not skip registering
backlight interface for it.

Hans de Goede bd8ba20597 ACPI / video: Filter the _BCL table for duplicate brightness values
Some devices have duplicate entries in there brightness levels table, ie
on my Dell Latitude E6430 the table looks like this:

[    3.686060] acpi backlight index   0, val 80
[    3.686095] acpi backlight index   1, val 50
[    3.686122] acpi backlight index   2, val 5
[    3.686147] acpi backlight index   3, val 5
[    3.686172] acpi backlight index   4, val 5
[    3.686197] acpi backlight index   5, val 5
[    3.686223] acpi backlight index   6, val 5
[    3.686248] acpi backlight index   7, val 5
[    3.686273] acpi backlight index   8, val 6
[    3.686332] acpi backlight index   9, val 7
[    3.686356] acpi backlight index  10, val 8
[    3.686380] acpi backlight index  11, val 9
etc.

Notice that brightness values 0-5 are all mapped to 5. This means that
if userspace writes any value between 0 and 5 to the brightness sysfs attribute
and then reads it, it will always return 0, which is somewhat unexpected.

This is a problem for ie gnome-settings-daemon, which uses read-modify-write
logic when the users presses the brightness up or down keys. This is done
this way to take brightness changes from other sources into account.

On this specific laptop what happens once the brightness has been set to 0,
is that gsd reads 0, adds 5, writes 5, and on the next brightness up key press
again reads 0, so things get stuck at the lowest brightness setting.

Filtering out the duplicate table entries, makes any write to brightness
read back as the written value as one would expect, fixing this.

Stephen Boyd 5ae8aabeae sched_clock: Prevent callers from seeing half-updated data
The generic sched_clock registration function was previously
done lockless, due to the fact that it was expected to be called
only once. However, now there are systems that may register
multiple sched_clock sources, for which the lack of locking has
casued problems:

If two sched_clock sources are registered we may end up in a
situation where a call to sched_clock() may be accessing the
epoch cycle count for the old counter and the cycle count for the
new counter. This can lead to confusing results where
sched_clock() values jump and then are reset to 0 (due to the way
the registration function forces the epoch_ns to be 0).

Fix this by reorganizing the registration function to hold the
seqlock for as short a time as possible while we update the
clock_data structure for a new counter. We also put any
accumulated time into epoch_ns instead of resetting the time to
0 so that the clock doesn't reset after each successful
registration.

Hsin-Yu Chao 13c12dbe3a ALSA: hda/ca0132 - Fix recording from mode id 0x8
Incorrect ADC is picked in ca0132_capture_pcm_prepare(),
where it assumes multiple streams while there is one stream
per ADC. Note that ca0132_capture_pcm_cleanup() already does
the right thing.

The Chromebook Pixel has a microphone under the keyboard that
is attached to node id 0x8. Before this fix, recording would
always go to the main internal mic (node id 0x7).

When a HDMI stream is opened with the same stream tag
as a following opened stream to ca0132, audio will be
heard from two ports simultaneously.
Fix this issue by change to use snd_hda_codec_setup_stream
and snd_hda_codec_cleanup_stream instead, so that an
inactive stream can be marked as 'dirty' when found
with a conflict stream tag, and then get purified.

Eric Sandeen 5ef11eb070 xfs: limit superblock corruption errors to actual corruption
Today, if

xfs_sb_read_verify
  xfs_sb_verify
    xfs_mount_validate_sb

detects superblock corruption, it'll be extremely noisy, dumping
2 stacks, 2 hexdumps, etc.

This is because we call XFS_CORRUPTION_ERROR in xfs_mount_validate_sb
as well as in xfs_sb_read_verify.

Also, *any* errors in xfs_mount_validate_sb which are not corruption
per se; things like too-big-blocksize, bad version, bad magic, v1 dirs,
rw-incompat etc - things which do not return EFSCORRUPTED - will
still do the whole XFS_CORRUPTION_ERROR spew when xfs_sb_read_verify
sees any error at all.  And it suggests to the user that they
should run xfs_repair, even if the root cause of the mount failure
is a simple incompatibility.

I'll submit that the probably-not-corrupted errors don't warrant
this much noise, so this patch removes the warning for anything
other than EFSCORRUPTED returns, and replaces the lower-level
XFS_CORRUPTION_ERROR with an xfs_notice().

Eric Sandeen daba5427da xfs: skip verification on initial "guess" superblock read
When xfs_readsb() does the very first read of the superblock,
it makes a guess at the length of the buffer, based on the
sector size of the underlying storage.  This may or may
not match the filesystem sector size in sb_sectsize, so
we can't i.e. do a CRC check on it; it might be too short.

In fact, mounting a filesystem with sb_sectsize larger
than the device sector size will cause a mount failure
if CRCs are enabled, because we are checksumming a length
which exceeds the buffer passed to it.

So always read twice; the first time we read with NULL
buffer ops to skip verification; then set the proper
read length, hook up the proper verifier, and give it
another go.

Once we are sure that we've got the right buffer length,
we can also use bp->b_length in the xfs_sb_read_verify,
rather than the less-trusted on-disk sectorsize for
secondary superblocks.  Before this we ran the risk of
passing junk to the crc32c routines, which didn't always
handle extreme values.

Eric Sandeen 7a01e707a3 xfs: xfs_sb_read_verify() doesn't flag bad crcs on primary sb
My earlier commit 10e6e65 deserves a layer or two of brown paper
bags.  The logic in that commit means that a CRC failure on the
primary superblock will *never* result in an error return.

Hopefully this fixes it, so that we always return the error
if it's a primary superblock, otherwise only if the filesystem
has CRCs enabled.
