[media] gspca_sonixj: Probe sensor type independent of bridge type
Looking at the windows inf file, for usb ids with a sensor type where probing
is needed to determine the type (for example ov7630 or soi768), this is
needed for all bridge variants with a usb id indicating this sensor type.
So do the probing to determine the actual sensor type for types where the
usb-id info is not 100% deterministic, independent of the bridge type.
If you look through the list of currently active usb ids in sonixj, this
effectively only changes the code path for 0c45:60fe (sn9c105 + ov7630) and
0c45:612e (sn9c110 + ov7630), which according to the inf file can have a
soi768 instead of a ov7630 just like the sn9c120 + ov7630 models where we
already probe for a soi7630.
The main reason for this code change is to keep the code paths as bridge
variant independent as possible, so that we don't need a lot of special
per bridge cases, as we enable more usb-ids in the future.
This change makes the 0c45:60fe code path identical to the successfully
tested 0c45:613e, so also make sonixj the default driver for 0c45:60fe.

Before this patch we were not setting the memory type to GSPCA_MEMORY_NO

the memory type be set to GSPCA_MEMORY_NO on device close, as capture_file
already is NULL on device close because of the reqbufs 0. This caused the
following problem:
-app1 does reqbufs USERPTR for 4 buffers
-app1 does reqbufs USERPTR for 0 buffers
-app2 tries to do reqbufs MMAP for 4 buffers
fails because gspca_dev->memory still is USERPTR
Fixing this also allows an app to switch memory type's by unrequesting
the buffers and re-requesting them of a different type.

to after alloc_frame succeeding, so that they are not changed when allocating

[media] gspca_main: Locking fixes 2
Before this patch vidioc_dqbuf is using its own read_lock, where as
other queue related functions use queue_lock. This means that dqbuf is
accessing several variables in a racy manor. The most important one
being fr_o, which may be changed from underneath dqbuf by vidioc_reqbufs
or vidioc_streamoff. Other variables which it accesses unprotected
are gspca_dev->memory, gspca_dev->streaming and gspca_dev->capt_file.
This patch fixes this by changing vidioc_dqbuf to also use the queue_lock.

The gspca_dev->streaming boolean is protected against multiple access
through gspca_dev->queue_lock everywhere except for 2 places. This patch
fixes this by bringing it under the lock in vidioc_streamoff. And by
removing the check for gspca_dev->streaming in gspca_disconnect,
the destroy_urbs call may be called multiple times (and is protected
by the usb_lock) and calling wake_up_interruptible can also always be done

In commit
411674fd189abe5910ea4caf08b7eac5c4a4d967 the tda9875 support was
added to tvaudio. This means that tda9875 is no longer used since mid-2009.
If there are out-of-tree users of this driver, then they can switch to tvaudio
instead.
The original commit message read as follows:
This change allows bttv to use tvaudio for this device. Since this device
has the same i2c address as the tda9874 we need to support both in the same
tvaudio driver. This makes it possible for tvaudio to detect which chip is
used. Originally the tda9875 was only available in the dedicated tda9875
driver, but that makes life very hard for bttv since loading tvaudio might
misdetect a tda9875 as a tda9874.
So there were good reasons for moving the tda9875 code into tvaudio.

MIPS: Add initial support for the Atheros AR71XX/AR724X/AR931X SoCs
This patch adds initial support for various Atheros SoCs based on the
MIPS 24Kc core. The following models are supported at the moment:
- AR7130
- AR7141
- AR7161
- AR9130
- AR9132
- AR7240
- AR7241
- AR7242
The current patch contains minimal support only, but the resulting
kernel can boot into user-space with using of an initramfs image on
various boards which are using these SoCs. Support for more built-in
devices and individual boards will be implemented in further patches.

On the off chance that uasm ever warns about overflow, there is no way

Change the printks to WARNs, so we can get a nice stack trace. It has
the added benefit of being much more noticeable than the short single

perf: Fix contexted inheritance
Linus reported that the RCU lockdep annotation bits triggered for this
rcu_dereference() because we're not holding rcu_read_lock().
Going over the code I cannot convince myself its correct:
- holding a ref on the parent_ctx, doesn't avoid it being uncloned
concurrently (as the comment says), so we can race with a free.
- holding parent_ctx->mutex doesn't avoid the above free from taking
place either, it would at best avoid parent_ctx from being freed.
I.e. the warning is correct. To fix the bug, serialize against the
unclone_ctx() call by extending the reach of the parent_ctx->lock.

x86: Make relocatable kernel work with new binutils
The CONFIG_RELOCATABLE=y option is broken with new binutils, which will make

According to Lu Hongjiu, the affected binutils are from 2.20.51.0.12 to
2.21.51.0.3, which are release since Oct 22 this year. At least ubuntu 10.10 is
using such binutils. See:
http://sourceware.org/bugzilla/show_bug.cgi?id=12327
The reason of the boot panic is that we have 'jiffies = jiffies_64;' in
vmlinux.lds.S. The jiffies isn't in any section. In kernel build, there is
warning saying jiffies is an absolute address and can't be relocatable. At
runtime, jiffies will have virtual address 0.
