Sam Ravnborg did the build-test that the direct header file move works,
I'm just committing it.
This is a pure move:
mkdir arch/alpha/include
git mv include/asm-alpha arch/alpha/include/asm
with no other changes.

A fuzzed fileystem image failed with OMFS when the extent count was
used in a loop without being checked against the max number of extents.
It also provoked a signed division for an array index that was checked
as if unsigned, leading to index by -1.
omfsck will be updated to fix these cases, in the meantime bail out
gracefully.

Testing with a modified fsfuzzer reveals a couple of locations in omfs
where filesystem variables are ultimately used as loop counters with
insufficient sanity checking. In this case, dir->i_size is used to
compute the number of buckets in the directory hash. If too large,
readdir will overrun a buffer.
Since it's an invariant that dir->i_size is equal to the sysblock
size, and we already sanity check that, just use that value instead.
This fixes the following oops:

When reviewing a recent patch I noticed a potential trouble spot in the
registration of new SPI devices. The SPI master driver is told to set
the device up before adding it to the driver model, so that it's always
properly set up when probe() is called. (This is important, because in
the case of inverted chipselects, this device can make the bus misbehave
until it's properly deselected. It's got to be set up even if no driver
binds to the device.)
The trouble spot is that it doesn't first verify that no other device
has been added using that chipselect. If such a device has been added,
its configuration gets trashed. (Fortunately this has not been a common
error!)
The fix here adds an explicit check, and a mutex to protect the relevant
critical region.

write_cache_pages() uses i_mapping->writeback_index to pick up where it
left off the last time a given inode was found by pdflush or
balance_dirty_pages (or anyone else who sets wbc->range_cyclic)
alloc_inode() should set it to a sane value so that writeback doesn't
start in the middle of a file. It is somewhat difficult to notice the bug
since write_cache_pages will loop around to the start of the file and the
elevator helps hide the resulting seeks.
For whatever reason, Btrfs hits this often. Unpatched, untarring 30
copies of the linux kernel in series runs at 47MB/s on a single sata
drive. With this fix, it jumps to 62MB/s.

Currently, all sensors are read when the energy meter is queried via
sysfs. This introduces a considerable amount of delay and variation in
the sysfs reading, which is not desirable when trying to profile energy
use. Therefore, read only the energy meters when a sysfs query comes in
for them, and don't cache the results so that we always get the latest
reading.

On older machines, probing for a nonexistent AEM interface returned an
IPMI error; when we saw this, we'd stop probing. On the x3650 M2 and
(presumably) later, we are returned a value indicating success and a
buffer full of garbage or zeroes. This causes the probe function to run
in an infinite loop. To fix this, we add one last check--if the
interface number we're looking for is higher than the number of
interfaces that AEM claims to have, stop probing.

Previously the driver was only using DMI to prevent smbus probing on
non-Abit motherboards. However, since the manual probing method is
brittle and prone to failure on some Abit motherboards (esp. the Abit
IP35 Pro) it is better to use DMI to also read the board name and then
decide whether or not to probe the bus.
At the moment, we do not have a list of valid DMI name strings to use
for existing and supported motherboards. This patch only implements DMI
probing for the IP35 Pro. For motherboards that can not yet use DMI
probing, a warning will be printed to the kernel log asking those users
to email me their dmidecode output.
The existing manual probing mechanism will be used if CONFIG_DMI is not
enabled, if DMI probing fails (for DMI-unsupported motherboards), or if
DMI probing fails and the "force" option is set (for DMI-supported
motherboards). Ideally in the longer term this manual probing method
would be removed.
This patch should be safe to apply as it does not change the probing
behaviour for most of the supported motherboards, just the IP35 Pro,
which already has regressions filed against it in 2.6.26.

This is the minimal sequence that jams the allocator:
void *p, *q, *r;
p = alloc_bootmem(PAGE_SIZE);
q = alloc_bootmem(64);
free_bootmem(p, PAGE_SIZE);
p = alloc_bootmem(PAGE_SIZE);
r = alloc_bootmem(64);
after this sequence (assuming that the allocator was empty or page-aligned
before), pointer "q" will be equal to pointer "r".
What's hapenning inside the allocator:
p = alloc_bootmem(PAGE_SIZE);
in allocator: last_end_off == PAGE_SIZE, bitmap contains bits 10000...
q = alloc_bootmem(64);
in allocator: last_end_off == PAGE_SIZE + 64, bitmap contains 11000...
free_bootmem(p, PAGE_SIZE);
in allocator: last_end_off == PAGE_SIZE + 64, bitmap contains 01000...
p = alloc_bootmem(PAGE_SIZE);
in allocator: last_end_off == PAGE_SIZE, bitmap contains 11000...
r = alloc_bootmem(64);
and now:
it finds bit "2", as a place where to allocate (sidx)
it hits the condition
if (bdata->last_end_off && PFN_DOWN(bdata->last_end_off) + 1 == sidx))
start_off = ALIGN(bdata->last_end_off, align);
-you can see that the condition is true, so it assigns start_off =
ALIGN(bdata->last_end_off, align); (that is PAGE_SIZE) and allocates
over already allocated block.
With the patch it tries to continue at the end of previous allocation only
if the previous allocation ended in the middle of the page.

Use platform_data to pass musb configuration-specific
details to musb driver.
This patch will prevent that other platforms selecting
HAVE_CLK and enabling musb won't break tree building.
The other parts of it will come when linux-omap merge
up more omap2/3 board-files.

If we try to modprobe a second gadget driver before
rmmoding the first one, the reference for the first
gadget driver would get NULLed avoiding usb to change
gadget drivers later.

This patch adds support for MUSB and TUSB controllers
integrated into omap2430 and davinci. It also adds support
for external tusb6010 controller.

These drivers should not be relying on CONFIG_USB_DEBUG. By doing this,
it prevents users of kernels that do not enable this option from
enabling debugging in these drivers, unlike all other usb-serial
drivers.

This adds the vendor and product id (19d2:0015) of the ZTE MF628 HSDPA
modem to the option driver. It still needs a mode switch command issued
beforehand, this is currently handled by a userspace tool.

On some AMD 700 series southbridges, ISO OUT transfers (such as audio
playback through speakers) on the USB OHCI controller may be corrupted
when an A-Link express power saving feature is active.
PLL power down mode in conjunction with link power management feature
L1 being enabled is the bad combination ... this patch prevents them
from being enabled when ISO transfers are pending.

Add a mechanism to let the write queue drain naturally before
closing the TTY, rather than always losing that data. There
is a timeout, so it can't wait too long.
Provide missing locking inside acm_wb_is_avail(); it matters
more now. Note, this presumes an earlier patch was applied,
removing a call to this routine where the lock was held.
Slightly improved diagnostics on write URB completion, so we
can tell when a write URB gets killed and, if so, how much
data it wrote first ... and so that I/O path is normally
silent (and can't much change timings).

The "increase cdc-acm write throughput" patch left in place two
now-obsolete mechanisms, either of which can make the cdc-acm
driver drop TX data (nasty!). This patch removes them:
- The write_ready flag ... if an URB and buffer were found,
they can (and should!) always be used.
- TX path acm_wb_is_used() ... used when the buffer was just
allocated, so that check is pointless.
Also fix a won't-yet-matter leak of a write buffer on a disconnect path.

Bugfixes to the usb_driver_release_interface() usage;
(a) make sure releasing *either* interface first will release
the other, instead of insisting it be the control interface;
(b) remove the recently-added self-deadlock.
(The "fix disconnect bug in cdc-acm" patch was incomplete and incorrect.)
Plus a small "sparse" fix: rename a local variable so it doesn't
shadow a function parameter.

Update the CDC-ACM gadget code to support the peripheral-to-host
notifications when the tty is opened or closed, or issues a BREAK.
The serial framework code calls new generic hooks; right now only
CDC-ACM uses those hooks. This resolves several REVISIT comments
in the code. (Based on a patch from Felipe Balbi.)
Note that this doesn't expose USB_CDC_CAP_BRK to the host, since
this code still rejects USB_CDC_REQ_SEND_BREAK control requests
for host-to-peripheral BREAK signaling (received via /dev/ttyGS*).
