MPSC serial driver tx locking
The MPSC serial driver assumes that interrupt is always on to pick up the
DMA transmit ops that aren't submitted while the DMA engine is active.
However when irqs are off for a period of time such as operations under
kernel crash dump console messages do not show up due to additional DMA ops
are being dropped. This makes console writes to process through all the tx
DMAs queued up before submitting a new request.
Also, the current locking mechanism does not protect the hardware registers
and ring buffer when a printk is done during the serial write operations.
The additional per port transmit lock provides a finer granular locking and
protects registers being clobbered while printks are nested within UART
writes.

serial: define FIXED_PORT flag for serial_core
At present, the serial core always allows setserial in userspace to change the
port address, irq and base clock of any serial port. That makes sense for
legacy ISA ports, but not for (say) embedded ns16550 compatible serial ports
at peculiar addresses. In these cases, the kernel code configuring the ports
must know exactly where they are, and their clocking arrangements (which can
be unusual on embedded boards). It doesn't make sense for userspace to change
these settings.
Therefore, this patch defines a UPF_FIXED_PORT flag for the uart_port
structure. If this flag is set when the serial port is configured, any
attempts to alter the port's type, io address, irq or base clock with
setserial are ignored.
In addition this patch uses the new flag for on-chip serial ports probed in
arch/powerpc/kernel/legacy_serial.c, and for other hard-wired serial ports
probed by drivers/serial/of_serial.c.

serial driver PMC MSP71xx
Serial driver patch for the PMC-Sierra MSP71xx devices.
There are three different fixes:
1 Fix for DesignWare APB THRE errata: In brief, this is a non-standard
16550 in that the THRE interrupt will not re-assert itself simply by
disabling and re-enabling the THRI bit in the IER, it is only re-enabled
if a character is actually sent out.
It appears that the "8250-uart-backup-timer.patch" in the "mm" tree
also fixes it so we have dropped our initial workaround. This patch now
needs to be applied on top of that "mm" patch.
2 Fix for Busy Detect on LCR write: The DesignWare APB UART has a feature
which causes a new Busy Detect interrupt to be generated if it's busy
when the LCR is written. This fix saves the value of the LCR and
rewrites it after clearing the interrupt.
3 Workaround for interrupt/data concurrency issue: The SoC needs to
ensure that writes that can cause interrupts to be cleared reach the UART
before returning from the ISR. This fix reads a non-destructive register
on the UART so the read transaction completion ensures the previously
queued write transaction has also completed.

add new_id to PCMCIA drivers
PCI drivers have the new_id file in sysfs which allows new IDs to be added
at runtime. The advantage is to avoid re-compilation of a driver that
works for a new device, but it's ID table doesn't contain the new device.
This mechanism is only meant for testing, after the driver has been tested
successfully, the ID should be added in source code so that new revisions
of the kernel automatically detect the device.
The implementation follows the PCI implementation. The interface is documented
in Documentation/pcmcia/driver.txt. Computations should be done in userspace,
so the sysfs string contains the raw structure members for matching.

Revert "[PATCH] x86: __pa and __pa_symbol address space separation"
This was broken. It adds complexity, for no good reason. Rather than
separate __pa() and __pa_symbol(), we should deprecate __pa_symbol(),
and preferably __pa() too - and just use "virt_to_phys()" instead, which
is more readable and has nicer semantics.
However, right now, just undo the separation, and make __pa_symbol() be
the exact same as __pa(). That fixes the bugs this patch introduced,
and we can do the fairly obvious cleanups later.
Do the new __phys_addr() function (which is now the actual workhorse for
the unified __pa()/__pa_symbol()) as a real external function, that way
all the potential issues with compile/link-time optimizations of
constant symbol addresses go away, and we can also, if we choose to, add
more sanity-checking of the argument.

it821x: PIO mode setup fixes
* limit max PIO mode to PIO4, this driver doesn't support PIO5 and attempt
to setup PIO5 by it821x_tuneproc() could result in incorrect PIO timings
+ incorrect base clock being set for controller in the passthrough mode
* move code limiting max PIO according to the pair device capabilities from
config_it821x_chipset_for_pio() to it821x_tuneproc() so the check is also
applied for mode change requests coming through ->tuneproc and ->speedproc
interfaces
* set device speed in it821x_tuneproc()
* in it821x_tune_chipset() call it821x_tuneproc() also if the controller is
in the smart mode (so the check for pair device max PIO is done)
* rename it821x_tuneproc() to it821x_tune_pio(), then add it821x_tuneproc()
wrapper which does the max PIO mode check; it worked by the pure luck
previously, pio[4] and pio_want[4] arrays were used with index == 255
so random PIO timings and base clock were set for the controller in the
passthrough mode, thankfully PIO timings and base clock were corrected
later by config_it821x_chipset_for_pio() call (but it was not called for
PIO-only devices during resume and for user requested PIO autotuning)
* remove config_it821x_chipset_for_pio() call from config_chipset_for_dma()
as the driver sets ->autotune to 1 and ->tuneproc does the proper job now
* convert the last user of config_it821x_chipset_for_pio() to use
it821x_tuneproc(drive, 255) and remove no longer needed function

total/active times instead of the clock counts, and convert them into the
active/recovery clocks there instead of cmd64x_tune_pio() -- this causes
quantize_timing() to also move;
- contrarywise, move all the code handling the address setup timing into

timings by twiddling bits in the BMIDE status register, handle setting MWDMA
by just calling program_cycle_times(); while at it, improve the style of that
whole switch statement;

not enable DMA, and are properly dealt with by the dma_host_{on,off} methods;
- don't set hwif->swdma_mask in the init_hwif() method anymore.

- in cmd64x_tune_pio(), when writing to ARTTIM23 register preserve the interrupt
status bit, eliminate local_irq_{save|restore}() around this code as there's
*no* actual race with the interrupt handler, and move cmdprintk() to a more
fitting place -- after ide_get_best_pio_mode() call;
- make {arttim|drwtim}_regs arrays single-dimensional, indexed with drive->dn;
- rename {setup|recovery}_counts[] into more fitting {setup|recovery}_values[];
- in the speedproc() method, get rid of the duplicate reads/writes from/to the

value after filtering, use another method of determining master/slave drive,

- Minor tweak to the 24xx non-wakeup gpio stuff: no need to check such

iomap: make the default iomap functions fail softer
We used to BUG_ON() for a badly mapped IO port, which is certainly
correct, but actually made it harder to debug the case where the ATA
drivers had incorrectly mapped a nonconnected ATA port.
So make badly mapped ports trigger a WARN_ON(), and throw the IO away
instead (and return all ones for reads). For things like broken driver
initialization - which is the most likely cause anyway - that should
mean that the machine comes up and is usable (at least that was the case
for the ATA breakage that triggered this patch).
It tends to be a whole lot easier to do a "dmesg" on a working machine
than to try to capture logs off a dead one.

[CIFS] Make sec=none force an anonymous mount
We had a customer report that attempting to make CIFS mount with a null
username (i.e. doing an anonymous mount) doesn't work. Looking through the
code, it looks like CIFS expects a NULL username from userspace in order
to trigger an anonymous mount. The mount.cifs code doesn't seem to ever
pass a null username to the kernel, however.
It looks also like the kernel can take a sec=none option, but it only seems
to look at it if the username is already NULL. This seems redundant and
effectively makes sec=none useless.
The following patch makes sec=none force an anonymous mount.

No longer send poll commands with the ADBREQ_REPLY flag -- doing that caused

Don't autopoll by continuously sending new Talk commands. Get the controller to
