The Inventra DMA engine in version 1.8 and later of the MUSB
controller cannot handle DMA addresses that are not aligned
to a 4 byte boundary. It ends up ignoring the last two bits
programmed in the DMA_ADDR register. This is a deliberate
design change in the controller and is documented in the
programming guide.
Earlier versions of the controller could handle these
accesses just fine.
Fail dma_channel_program if we see an unaligned address when
using the newer controllers, so that the caller can carry out
the transfer using PIO mode.

All of the hard problems for BKL removal appear to be solved in the
v4l-dvb/master tree. This removes the BKL from the various open
functions that do not need it, or only use it to protect an
open count.
The zoran driver is nontrivial in this regard, so I introduce
a new mutex that locks both the open/release and the ioctl
functions. Someone with access to the hardware can probably
improve that by using the existing lock in all cases.
Finally, all drivers that still use the locked version of the
ioctl function now get called under a new mutex instead of
the BKL.

Bit 22 of AR_WA should be set to fix the situation where chip reset
is asynchronous to clock of analog shift registers, such that when
reset is released, it could mess up the values of analog shift registers
and cause some hw issue on AR9280.
This bit is write only, but the driver does a read-modify-write
on AR_WA without setting bit 22 in ar9002_hw_configpcipowersave()
during radio disable. This causes surprise removal of hw. It can
never recover from this state and the hw will become usable only
after a power on/off cycle, and sometimes only during a cold reboot.
This issue can be triggered by doing frequent roaming with the
simple/test-roam script available from the wifi-test project [1]
when roaming between APs quickly. When roaming there is a is a high
possibility that the device being put into idle (radio disable) state

- libipw_proc = proc_mkdir(DRV_NAME, init_net.proc_net);
+ libipw_proc = proc_mkdir("ieee80211", init_net.proc_net);
but then the cleanup was kept as
remove_proc_entry(DRV_NAME, init_net.proc_net);
in both places (both in the failure case and in the unload case). The
error string is also total crap, and says
"Unable to create " DRV_NAME " proc directory\n");
Even though it doesn't actually create a proc directory named DRV_NAME at all.
So that patch looks like total and utter crap to me. The commit message says
"Keep /proc/net/ieee80211 under the original name to avoid breaking user
interface."
but the thing is, it really didn't fix anything but that one create
thing. It needs to fix all the other cases too.

Commit 27ae60f8f7 ("ipw2x00: replace "ieee80211" with "libipw" where
appropriate") changed DRV_NAME to be "libipw", but didn't properly fix
up the places where it was used to specify the name for the /proc/net/
directory.
For backwards compatibility reasons, that directory name remained
"ieee80211", but due to the DRV_NAME change, the error case printouts
and the cleanup functions now used "libipw" instead. Which made it all
fail badly.
For example, on module unload as reported by Randy:
WARNING: at fs/proc/generic.c:816 remove_proc_entry+0x156/0x35e()
name 'libipw'
because it's trying to unregister a /proc directory that obviously
doesn't even exist.
Clean it all up to use DRV_PROCNAME for the actual /proc directory name.

Commit 9f445cb29918dc488b7a9a92ef018599cce33df7[USB: musb: disable
double buffering for older RTL versions] tries to disable double
buffer mode by writing endpoint hw max packet size to TXMAP/RXMAP.
First the approach can break full speed and cause overflow problems.
We should always set those registers with the actual max packet size
from endpoint descriptor.
Second, the problem describe by commit 9f445cb299
was caused by musb gadget driver; nothing to do with RTL revision as
originaly suspected.
The real fix to the problem is to always use actual max packet
size from endpoint descriptor to config TXMAP/RXMAP registers.

Some actions like musb_platform_exit are only performed on module
removal and not on shutdown, which results in PHY being left enabled
on reboot at least. This is sometimes causing strange failures after
reboot (observed on OMAP3 pandora board), when DEVCTL does not report
VBUS state correctly due to unknown reasons (possibly because of
communication issues between musb IP and PHY). Running
musb_platform_exit before reset seems to resolve that issue.
Move some exit code from musb_remove() to musb_shutdown() so that it
is performed on both module removal and shutdown/reset. Also convert
the host check so that it doesn't need #ifdef.

On certain VIA chipsets AES-CBC requires the input/output to be
a multiple of 64 bytes. We had a workaround for this but it was
buggy as it sent the whole input for processing when it is meant
to only send the initial number of blocks which makes the rest
a multiple of 64 bytes.
As expected this causes memory corruption whenever the workaround

Many of the IBM Terminal keyboards from the 1980s and early 1990s communicate
using a protocol similar, but not identical to the AT keyboard protocol.
(Models known to be like this include 6110344, 6110668, 1390876, 1386887, and
possibly others.)
When the connector is rewired or adapter to an AT-DIN or PS/2 connector, they
can be connected to a standard PC, with three caveats:
a) They can only use scancode set 3; requests to use anything else are
quietly ignored.
b) The AT Command to request Make, Break and Repeat codes is not properly
interpreted.
c) The top function keys on a 122 key keyboard, and the arrow/edit keys in
the middle of the board send non-standard scancodes.
C) is easily taken care of in userspace, by use of setkeycodes
B) can be taken care of by a userspace hack (that makes the kernel complain
in dmesg)
A) is fixable in theory, but on the keyboard i tested on (6110668), it seems
to be detected unoverridably as Set 2, causing userspace oddities that make
it harder to fix C).
Enclosed is a small patch to the kernel that fixes A) and B) in the kernel,
making it much easier to fix C) in userspace. It adds a single kernel
command line parameter that overrides the detection that sets these boards
as set 2, and instead of sending the Make-break-repeat command to the
keyboard, it sends the make-break command, which is properly recognized by
these keyboards. Software level key repeating seems to make up for the lack
of hardware repeat codes perfectly.
Without manually setting the command line parameter (tentatively named
atkbd.terminal), this code has no effect, and the driver works exactly as
before.

Part of the issue here was that Eric slipped in a debug hack for
testing the i915 IPS code before the intel_ips.c driver had landed.
This caused the driver to always use the full range of frequencies,
which is only legal when IPS tells us we have the headroom. Once that
hack was removed, there was confusion about the driver's frequency
clamping variables: max_delay is the driver's current limit on the
highest frequency the IPS driver wants us to use, while dev_priv->fmax
is the hardware-reported limit that the IPS driver can increase up to.
Tested with IPS driver loaded or not. Note that on Ironlake systems
without the IPS driver loaded this will result in a performance
reduction, and the inital warmup of frequency limits can impact
benchmarking on systems with IPS loaded.

If the controller is storing a split packet and therefore changing
d->res_count to zero between the two reads by the driver, we end up with
an end pointer that is not at a packet boundary, and therefore overflow
the buffer when handling the split packet.
To fix this, read the field once, atomically. The compiler usually
merges the two reads anyway, but for correctness, we have to enforce it.

Freeing an AR buffer page just to allocate a new page immediately

When handling an AR buffer that has been completely filled, we assumed
that its descriptor will not be read by the controller and can be
overwritten. However, when the last received packet happens to end at
the end of the buffer, the controller might not yet have moved on to the
next buffer and might read the branch address later. If we overwrite
and free the page before that, the DMA context will either go dead
because of an invalid Z value, or go off into some random memory.
To fix this, ensure that the descriptor does not get overwritten by
using only the actual buffer instead of the entire page for reassembling
the split packet. Furthermore, to avoid freeing the page too early,
move on to the next buffer only when some data in it guarantees that the
controller has moved on.
This should eliminate the remaining firewire-net problems.

When the controller had to split a received asynchronous packet into two
buffers, the driver tries to reassemble it by copying both parts into
the first page. However, if size + rest > PAGE_SIZE, i.e., if the yet
unhandled packets before the split packet, the split packet itself, and
any received packets after the split packet are together larger than one
page, then the memory after the first page would get overwritten.
To fix this, do not try to copy the data of all unhandled packets at
once, but copy the possibly needed data every time when handling
a packet.
This gets rid of most of the infamous crashes and data corruptions when
using firewire-net.

read_lock(&tasklist_lock);
tty_audit_push_task();

--> buf->mutex is locked with preemption disabled.
Solve this by acquiring a reference to the task struct under

tty_audit_push_task() and use lock/unlock_sighand as we do not hold

The "kgdb_connected" variable of debug_core just indicates whether or
not kgdbts is connected to the debug_core. It does not completely
prevent a script from trying invoke kgdbts again and possibly crashing
the system (see Call Trace below).
The configured variable in kgtbts can be used instead of
kgdb_connected instead of kgdb_connected. The cleanup_kgdbts() can
also be removed because there is no possible way to build kgdbts as a
kernel module that you could unload with rmmod.

...
The OCTEON II SOC has USB EHCI and OHCI controllers connected directly
to the internal I/O bus. This patch adds the necessary 'glue' logic
to allow ehci-hcd and ohci-hcd drivers to work on OCTEON II.
The OCTEON normally runs big-endian, and the ehci/ohci internal
registers have host endianness, so we need to select
USB_EHCI_BIG_ENDIAN_MMIO.
The ehci and ohci blocks share a common clocking and PHY
infrastructure. Initialization of the host controller and PHY clocks
is common between the two and is factored out into the
octeon2-common.c file.
Setting of USB_ARCH_HAS_OHCI and USB_ARCH_HAS_EHCI is done in
arch/mips/Kconfig in a following patch.

The creation of the I/O clock domain requires some adjustments. Since
the watchdog counters are clocked by the I/O clock, use its rate for
timing calculations.

The following are the fixes in this patch:
1. Added support of set timestamp command in the driver
2. Pass all status code to mgmt application. Earlier we were passing
only failed ones.
3. Call class_destroy after unregister_chrdev and pci_unregister_driver
