5e9c85d983 [media] dib8096: enhancement
The intend of this patch is to improve the support of the dib8096. The PLL
parameters are not automatically computed. The limit to set/unset external
diode for attenuation has been updated. The TFE8096P board is using the
new I2C API.

79d852bf5e NFS: Retry SETCLIENTID with AUTH_SYS instead of AUTH_NONE
Recently I changed the SETCLIENTID code to use AUTH_GSS(krb5i), and
then retry with AUTH_NONE if that didn't work.  This was to enable
Kerberos NFS mounts to work without forcing Linux NFS clients to
have a keytab on hand.

Rick Macklem reports that the FreeBSD server accepts AUTH_NONE only
for NULL operations (thus certainly not for SETCLIENTID).  Falling
back to AUTH_NONE means our proposed 3.10 NFS client will not
interoperate with FreeBSD servers over NFSv4 unless Kerberos is
fully configured on both ends.

If the Linux client falls back to using AUTH_SYS instead for
SETCLIENTID, all should work fine as long as the NFS server is
configured to allow AUTH_SYS for SETCLIENTID.

This may still prevent access to Kerberos-only FreeBSD servers by
Linux clients with no keytab.  Rick is of the opinion that the
security settings the server applies to its pseudo-fs should also
apply to the SETCLIENTID operation.

Linux and Solaris NFS servers do not place that limitation on
SETCLIENTID.  The security settings for the server's pseudo-fs are
determined automatically as the union of security flavors allowed on
real exports, as recommended by RFC 3530bis; and the flavors allowed
for SETCLIENTID are all flavors supported by the respective server
implementation.

5ddfbbb9ca [media] cx88: Fix unsafe locking in suspend-resume
Legacy PCI suspend-resume handlers are called with interrupts enabled.

But cx8800_suspend/cx8800_resume and
cx8802_suspend_common/cx8802_resume_common use spin_lock/spin_unlock
functions to acquire dev->slock, while the same lock is acquired in the
corresponding irq-handlers: cx8800_irq and cx8802_irq.

That means a deadlock is possible if an interrupt happens while suspend
or resume owns the lock. The patch replaces spin_lock/spin_unlock with
spin_lock_irqsave/spin_unlock_irqrestore.

a50188dae3 acpi: video: enhance the quirk detect logic of _BQC
Currently we decide if the _BQC is using index by first setting the
level to maximum, and then check if _BQC returned maximum; if not, we
say it is using index.

This is not true for some buggy systems, where the _BQC method will
always return a constant value(e.g. 0 or 100 for the two broken system)
and thus break the current logic. So this patch tries to enhance the
quirk detect logic for _BQC: we do this by picking a test_level, it can
be the maximum level or the mininum one based on some condition. And we
don't make the assumption that if _BQC returned a value that is not what
we just set, it must be using an index. Instead, we will compare the
value returned from _BQC and if it doesn't match, see if the returned
value is an index. And if still no, clear the capability of _BQC.

0b4184c26b metag: avoid unnecessary builtin dtb rebuilds
The builtin .dtb.S intermediate file needs to be marked with .SECONDARY
so that it isn't automatically deleted (which causes it to be
regenerated on every build). Also add *.dtb.S to clean-files so it gets
cleaned up by make clean.

Similarly, if the specified builtin dtb isn't already in dtb-y (e.g.
imported into the tree and specified in CONFIG_METAG_BUILTIN_DTB_NAME)
it too will be treated as an intermediate and deleted automatically
(again causing it to be regenerated on every build), so add it to dtb-y
so it gets added to targets and the dtbs target.

3dcb9f1b17 ARM: OMAP3: remove cpuidle_wrap_enter
In a previous commit the en_core_tk_irqen flag has been added but we missed
the cpuidle_wrap_enter which was doing the job to measure the time for the
'omap3_enter_idle' function.

Actually, I don't see any reason to use this wrapper in the code. In the better
case, the time computation is not correctly done because of the different
operations done in omap3_enter_idle_bm which were not taken into account
before the en_core_tk_irqen flag was set.

As the time is reflected for the state overridden by the omap3_enter_idle_bm,
using the wrapper is pointless now, so removing it.

1dfd89af86 LOCKD: Ensure that nlmclnt_block resets block->b_status after a server reboot
After a server reboot, the reclaimer thread will recover all the existing
locks. For locks that are blocked, however, it will change the value
of block->b_status to nlm_lck_denied_grace_period in order to signal that
they need to wake up and resend the original blocking lock request.

Due to a bug, however, the block->b_status never gets reset after the
blocked locks have been woken up, and so the process goes into an
infinite loop of resends until the blocked lock is satisfied.

34f8f1031c ACPI: update comments for acpi_event_status
ACPI_EVENT_FLAG_HANDLE is a flag for acpi_event_status.
When it is set, it indicates that the ACPI event,
either GPE or fixed event, is associated with a handler.

Update the comments to reflect this flag.
