ARM: mach-shmobile: ap4evb: FSI clock use proper process for HDMI
Current AP4 FSI set_rate function used bogus clock process
which didn't care enable/disable and clk->usecound.
To solve this issue, this patch also modify FSI driver to call
set_rate with enough options.

of/phylib: Use device tree properties to initialize Marvell PHYs.
Some aspects of PHY initialization are board dependent, things like
indicator LED connections and some clocking modes cannot be determined
by probing. The dev_flags element of struct phy_device can be used to
control these things if an appropriate value can be passed from the
Ethernet driver. We run into problems however if the PHY connections
are specified by the device tree. There is no way for the Ethernet
driver to know what flags it should pass.
If we are using the device tree, the struct phy_device will be
populated with the device tree node corresponding to the PHY, and we
can extract extra configuration information from there.
The next question is what should the format of that information be?
It is highly device specific, and the device tree representation
should not be tied to any arbitrary kernel defined constants. A
straight forward representation is just to specify the exact bits that
should be set using the "marvell,reg-init" property:
The Marvell PHYs have a page select register at register 22 (0x16), we
can specify any register by its page and register number. These are
the first and second word. The third word contains a mask to be ANDed
with the existing register value, and the fourth word is ORed with the
result to yield the new register value. The new marvell_of_reg_init
function leaves the page select register unchanged, so a call to it
can be dropped into the .config_init functions without unduly
affecting the state of the PHY.
If CONFIG_OF_MDIO is not set, there is no of_node, or no
"marvell,reg-init" property, the PHY initialization is unchanged.

When I did my first PA testing recently, the period size bug resulted
in quite precisely observeable half-period-based playback distortion.
PA-based operation is quite a bit more underrun-prone (despite its
zero-copy optimizations etc.) than raw ALSA with this rather spartan
sound hardware implementation on my puny Athlon.
Note that even with this patch, azt3328 still doesn't work for both
cases yet, PA tsched=0 and tsched
(on tsched=0 it will playback tiny fragments of periods, leading to tiny
stuttering sounds with some pauses in between, whereas with
timer-scheduled operation playback works fine - minus some quite increased
underrun trouble on PA vs. ALSA, that is).

Filesystem independent ioctl was rejected as not common enough to be in

commit adds ext4 specific ioctl EXT4_IOC_TRIM to dispatch
ext4_trim_fs().
It takes fstrim_range structure as an argument. fstrim_range is definec in
the include/linux/fs.h and its definition is as follows.
start - first Byte to trim
len - number of Bytes to trim from start
minlen - minimum extent length to trim, free extents shorter than this
number of Bytes will be ignored. This will be rounded up to fs
block size.
After the FITRIM is done, the number of actually discarded Bytes is stored
in fstrim_range.len to give the user better insight on how much storage
space has been really released for wear-leveling.

At first I thought it actually hung the box, but it continued booting
after 5 minutes, and I was able to log in. It dropped back to the
text console instead of the graphical bootup display for that period
of time. dmesg surprisingly still works. I've bisected the problem
down to this commit (commit 59365d136d205cc20fe666ca7f89b1c5001b0d5a)
The box is running klogd 1.5.5ubuntu3 (from Jaunty). Yes, I know
that's old. I read the bit in the commit about changing the
permissions of kallsyms after boot, but if I can't boot that doesn't
help."
So let's just keep the old default, and encourage distributions to do
the "chmod -r /proc/kallsyms" in their bootup scripts. This is not
worth a kernel option to change default behavior, since it's so easily
done in user space.

Both IBX and CPT have an automatic hotplug detection mode which appears to work reliably enough
that we can dispense with the manual force hotplug trigger stuff. This means that
hotplug detection is as simple as reading the current hotplug register values.
The first time the hotplug detection is activated, the code synchronously waits for a hotplug
sequence in case the hardware hasn't bothered to do a detection cycle since being initialized.

drm/i915: Do not hold mutex when faulting in user addresses
Linus Torvalds found that it was rather trivial to trigger a system
freeze:
In fact, with lockdep, I don't even need to do the sysrq-d thing: it
shows the bug as it happens. It's the X server taking the same lock
recursively.
Here's the problem:
=============================================
[ INFO: possible recursive locking detected ] 2.6.37-rc2-00012-gbdbd01a #7
---------------------------------------------
Xorg/2816 is trying to acquire lock:
(&dev->struct_mutex){+.+.+.}, at: [<ffffffff812c626c>] i915_gem_fault+0x50/0x17e
but task is already holding lock:
(&dev->struct_mutex){+.+.+.}, at: [<ffffffff812c403b>] i915_mutex_lock_interruptible+0x28/0x4a
other info that might help us debug this:
2 locks held by Xorg/2816:
#0: (&dev->struct_mutex){+.+.+.}, at: [<ffffffff812c403b>] i915_mutex_lock_interruptible+0x28/0x4a
#1: (&mm->mmap_sem){++++++}, at: [<ffffffff81022d4f>] page_fault+0x156/0x37b
This recursion was introduced by rearranging the locking to avoid the
double locking on the fast path (4f27b5d and fbd5a26d) and the
introduction of the prefault to encourage the fast paths (b5e4f2b). In
order to undo the problem, we rearrange the code to perform the access
validation upfront, attempt to prefault and then fight for control of the
mutex. the best case scenario where the mutex is uncontended the
prefaulting is not wasted.
