The patch set beginning with commit:
"ARM: ux500: Apply a ste-* prefix onto snowball.dts"
thru commit:
"ARM: ux500: Remove u9540.dts as it's been replaced"
altered the names of the ux500 device tree files but forgot
to:
- Rename the ccu8540-pinctrl.dtsi file
- Update #include statements from files using these
files, so the build broke.
- Update the Makefile for the device trees so the build
broke.
Fix it up so we can build them all again.

Instead of evenly splitting the 512 MiB area between prefetchable and
non-prefetchable memory spaces, increase the prefetchable memory space
to 384 MiB while at the same time decreasing the non-prefetchable memory
space to 128 MiB. This is a more useful default as most PCIe devices
require more prefetchable than non-prefetchable memory.

Beaver's PCIe lane configuration most closely matches x2 x2 x2 rather
than x4 x1 x1, since clocks 0 and 2 are used, and lanes 0 and 5 are used,
and the only way those align is with a x2 x2 x2 configuration.
Also, disable root port 1; there's nothing connected to it. Root port 0
is the on-board PCIe Ethernet, and port 2 is the mini-PCIe slot.

When btrfs readdir() hits the last entry it sets the readdir offset to a
huge value to stop buggy apps from breaking when the same name is
returned by readdir() with concurrent rename()s.
But unconditionally setting the offset to INT_MAX causes readdir() to
loop returning any entries with offsets past INT_MAX. It only takes a
few hours of constant file creation and removal to create entries past
INT_MAX.
So let's set the huge offset to LLONG_MAX if the last entry has already
overflowed 32bit loff_t. Without large offsets behaviour is identical.
With large offsets 64bit apps will work and 32bit apps will be no more
broken than they currently are if they see large offsets.

I noticed while running multi-threaded fsync tests that sometimes fsck would
complain about an improper gap. This happens because we fail to add a hole
extent to the file, which was happening when we'd split a hole EM because
btrfs_drop_extent_cache was just discarding the whole em instead of splitting
it. So this patch fixes this by allowing us to split a hole em properly, which
means that added holes actually get logged properly and we no longer see this
fsck error. Thankfully we're tolerant of these sort of problems so a user would
not see any adverse effects of this bug, other than fsck complaining. Thanks,

Because we don't mess with the offset into the extent for compressed we will
properly find both extents for this case
[extent a][extent b][rest of extent a]
but because we already added a ref for the front half we won't add the inode
information for the second half. This causes us to leak that memory and not
print out the other offset when we do logical-resolve. So fix this by calling
ulist_add_merge and then add our eie to the existing entry if there is one.
With this patch we get both offsets out of logical-resolve. With this and the
other 2 patches I've sent we now pass btrfs/276 on my vm with compress-force=lzo
set. Thanks,

If you do btrfs inspect-internal logical-resolve on a compressed extent that has
been partly overwritten it won't find anything. This is because we try and
match the extent offset we've searched for based on the extent offset in the
data extent entry. However this doesn't work for compressed extents because the
offsets are for the uncompressed size, not the compressed size. So instead only
do this check if we are not compressed, that way we can get an actual entry for
the physical offset rather than nothing for compressed. Thanks,

xfstest btrfs/276 was freaking out on slower boxes partly because fiemap was
offsetting the physical based on the extent offset. This is perfectly fine with
uncompressed extents, however the extent offset is into the uncompressed area,
not the compressed. So we can return a physical value that isn't at all within
the area we have allocated on disk. Fix this by returning the start of the
extent if it is compressed no matter what the offset. Thanks,

For partial extents, snapshot-aware defrag does not work as expected,
since
a) we use the wrong logical offset to search for parents, which should be
disk_bytenr + extent_offset, not just disk_bytenr,
b) 'offset' returned by the backref walking just refers to key.offset, not
the 'offset' stored in btrfs_extent_data_ref which is
(key.offset - extent_offset).
The reproducer:
$ mkfs.btrfs sda
$ mount sda /mnt
$ btrfs sub create /mnt/sub
$ for i in `seq 5 -1 1`; do dd if=/dev/zero of=/mnt/sub/foo bs=5k count=1 seek=$i conv=notrunc oflag=sync; done

Create a small file and fallocate it to a big size with
FALLOC_FL_KEEP_SIZE option, then truncate it back to the
small size again, the disk free space is not changed back
in this case. i.e,
total 4
-rw-r--r-- 1 root root 512 Jun 28 11:35 test
Filesystem Size Used Avail Use% Mounted on
....
/dev/sdb1 8.0G 56K 7.2G 1% /mnt
-rw-r--r-- 1 root root 512 Jun 28 11:35 /mnt/test
Filesystem Size Used Avail Use% Mounted on
....
/dev/sdb1 8.0G 5.1G 2.2G 70% /mnt
Filesystem Size Used Avail Use% Mounted on
....
/dev/sdb1 8.0G 5.1G 2.2G 70% /mnt
With this fix, the truncated up space is back as:
Filesystem Size Used Avail Use% Mounted on
....
/dev/sdb1 8.0G 56K 7.2G 1% /mnt

Pull ACPI and power management fixes from Rafael Wysocki:
- ACPI-based memory hotplug stopped working after a recent change,
because it's not possible to associate sufficiently many "physical"
devices with one ACPI device object due to an artificial limit. Fix
from Rafael J Wysocki removes that limit and makes memory hotplug
work again.
- A change made in 3.9 uncovered a bug in the ACPI processor driver
preventing NUMA nodes from being put offline due to an ordering
issue. Fix from Yasuaki Ishimatsu changes the ordering to make
things work again.
- One of the recent ACPI video commits (that hasn't been reverted so
far) uncovered a bug in the code handling quirky BIOSes that caused
some Asus machines to boot with backlight completely off which made
it quite difficult to use them afterward. Fix from Felipe Contreras
improves the quirk to cover this particular case correctly.
- A cpufreq user space interface change made in 3.10 inadvertently
renamed the ignore_nice_load sysfs attribute to ignore_nice which
resulted in some confusion. Fix from Viresh Kumar changes the name
back to ignore_nice_load.
- An initialization ordering change made in 3.9 broke cpufreq on
loongson2 boards. Fix from Aaro Koskinen restores the correct
initialization ordering there.
- Fix breakage resulting from a mistake made in 3.9 and causing the
detection of some graphics adapters (that were detected correctly
before) to fail. There are two objects representing the same PCIe
port in the affected systems' ACPI tables and both appear as
"enabled" and we are expected to guess which one to use. We used to
choose the right one before by pure luck, but when we tried to
address another similar corner case, the luck went away. This time
we try to make our guessing a bit more educated which is reported to
work on those systems.
- The /proc/acpi/wakeup interface code is missing some locking which
may lead to breakage if that file is written or read during hotplug
of wakeup devices. That should be rare but still possible, so it's
better to start using the appropriate locking there.
