Ferruh Yigit 17fb1563d6 Input: cyttsp4 - add core driver for Cypress TMA4XX touchscreen devices
Cypress TrueTouch(tm) Standard Product controllers,
Generetion4 devices, Core driver.

Core driver is interface between host and TTSP controller and processes
data sent by controller.

Responsibilities of module are IRQ handling, reading system information
registers and sending multi-touch protocol type B events.

Ferruh Yigit 9664877ed8 Input: cyttsp - I2C driver split into two modules
Existing I2C code is for TrueTouch Gen3 devices

TrueTouch Gen4 device is using same protocol, will split driver into
two pieces to use common code with both drivers.

Read/Write functions parameter list modified, since shared code will
be used by two separate drivers and these drivers are not sharing same
structs, parameters updated to use common structures.

Daniel Drake b56ece9a3a Input: add OLPC AP-SP driver
The OLPC XO-1.75 and XO-4 laptops include a PS/2 touchpad and an AT
keyboard, yet they do not have a hardware PS/2 controller. Instead, a
firmware runs on a dedicated core ("Security Processor", part of the SoC)
that acts as a PS/2 controller through bit-banging.

Communication between the main cpu (Application Processor) and the
Security Processor happens via a standard command mechanism implemented
by the SoC. Add a driver for this interface to enable keyboard/mouse
input on this platform.

Peter Hutterer 257867dc8d Input: MT - Specify that ABS_MT_SLOT must have a minimum of 0
This is effectively already in force through input_mt_init_slots, and uinput
too ignores the actual minimum.

Since slots are a kernel-genenerated axis only, non-zero minimums make
little sense and are likely to cause errors. Better to treat a non-zero
minimum as kernel bug if it ever happens.

David Herrmann 483180281f Input: evdev - flush queues during EVIOCGKEY-like ioctls
If userspace requests current KEY-state, they very likely assume that no
such events are pending in the output queue of the evdev device.
Otherwise, they will parse events which they already handled via
EVIOCGKEY(). For XKB applications this can cause irreversible keyboard
states if a modifier is locked multiple times because a CTRL-DOWN event is
handled once via EVIOCGKEY() and once from the queue via read(), even
though it should handle it only once.

Therefore, lets do the only logical thing and flush the evdev queue
atomically during this ioctl. We only flush events that are affected by
the given ioctl.

This only affects boolean events like KEY, SND, SW and LED. ABS, REL and
others are not affected as duplicate events can be handled gracefully by
user-space.

Note: This actually breaks semantics of the evdev ABI. However,
investigations showed that userspace already expects the new semantics and
we end up fixing at least all XKB applications.
All applications that are aware of this race-condition mirror the KEY
state for each open-file and detect/drop duplicate events. Hence, they do
not care whether duplicates are posted or not and work fine with this fix.

Also note that we need proper locking to guarantee atomicity and avoid
dead-locks. event_lock must be locked before queue_lock (see input-core).
However, we can safely release event_lock while flushing the queue. This
allows the input-core to proceed with pending events and only stop if it
needs our queue_lock to post new events.
This should guarantee that we don't block event-dispatching for too long
while flushing a single event queue.

The first two fix the case where full RCU debugging is enabled, enabling
 function tracing causes a live lock of the system. This is due to the added
 debug checks in rcu_dereference_raw() that is used by the function tracer.
 These checks are also traced by the function tracer as well as cause enough
 overhead to the function tracer to slow down the system enough that
 the time to finish an interrupt can take longer than when the next
 interrupt is triggered, causing a live lock from the timer interrupt.
 
 Talking this over with Paul McKenney, we came up with a fix that adds
 a new rcu_dereference_raw_notrace() that does not perform these added checks,
 and let the function tracer use that.
 
 The third commit fixes a failed compile when branch tracing is enabled,
 due to the conversion of the trace_test_buffer() selftest that the
 branch trace wasn't converted for.
 
 The forth patch fixes a bug caught by the RCU lockdep code where a
 rcu_read_lock() is performed when rcu is disabled (either going to
 or from idle, or user space). This happened on the irqsoff tracer
 as it calls task_uid(). The fix here was to use current_uid() when
 possible that doesn't use rcu locking. Which luckily, is always used
 when irqsoff calls this code.

Olof Johansson 090878aa95 The mxs fixes for 3.10:
- Since the time we move to MULTI_IRQ_HANDLER, the 0x7f polling for no
   interrupt in icoll_handle_irq() becomes insane, because 0x7f is an
   valid interrupt number, the irq of gpio bank 0.  That unnecessary
   polling results in the driver not detecting when irq 0x7f is active
   which makes the machine effectively dead lock.  The fix removes the
   interrupt poll loop and allows usage of gpio0 interrupt without an
   infinite loop.

   The clock is needed by spi driver to calculate bit rate divisor.
   The spi node in the current device trees either does not have the
   clock or is defined as dummy clock, in which case the driver probe
   will fail or spi will run at a wrong bit rate.

Doug Anderson 9c1fcdccc7 ARM: exynos: add debug_ll_io_init() call in exynos_init_io()
If the early MMU mapping of the UART happens to get booted out of the
TLB between the start of paging_init() and when we finally re-add the
UART at the very end of s3c_init_cpu(), we'll get a hang at bootup if
we've got early_printk enabled.  Avoid this hang by calling
debug_ll_io_init() early.

Without this patch, you can reliably reproduce a hang when early
printk is enabled by adding flush_tlb_all() at the start of
exynos_init_io().  After this patch the hang goes away.

Tushar Behera 437d8ac510 ARM: EXYNOS: uncompress - print debug messages if DEBUG_LL is defined
Printing low-level debug messages make an assumption that the specified
UART port has been preconfigured by the bootloader. Incorrectly
specified UART port results in system getting stalled while printing the
message "Uncompressing Linux... done, booting the kernel"
This UART port number is specified through S3C_LOWLEVEL_UART_PORT. Since
the UART port might different for different board, it is not possible to
specify it correctly for every board that use a common defconfig file.

Calling this print subroutine only when DEBUG_LL fixes the problem. By
disabling DEBUG_LL in default config file, we would be able to boot
multiple boards with different default UART ports.

With this current approach, we miss the print "Uncompressing Linux...
done, booting the kernel." when DEBUG_LL is not defined.

Commit b378549 (ACPI / PM: Do not power manage devices in unknown
initial states) added code to force devices without _PSC, but having
_PS0 defined in the ACPI namespace, into ACPI power state D0 by
executing _PS0 for them.  That turned out to break Toshiba P870-303,
however, so revert that code.

Pull networking fix from David Miller:
 "This is a quick one commit pull request to cure the regression
  introduced by the MSG_CMSG_COMPAT change."

(Background: commit 1be374a051 completely broke 32-bit COMPAT handling
by not only disallowing MSG_CMSG_COMPAT from user APIs, but clearing it
in our own internal use too!)

Pull more xfs updates from Ben Myers:
 "Here are several fixes for filesystems with CRC support turned on:
  fixes for quota, remote attributes, and recovery.  There is also some
  feature work related to CRCs: the implementation of CRCs for the inode
  unlinked lists, disabling noattr2/attr2 options when appropriate, and
  bumping the maximum number of ACLs.

  I would have preferred to defer this last category of items to 3.11.
  This would require setting a feature bit for the on-disk changes, so
  there is some pressure to get these in 3.10.  I believe this
  represents the end of the CRC related queue.

   - Rework of dquot CRCs
   - Fix for remote attribute invalidation of a leaf
   - Fix ordering of transaction replay in recovery
   - Implement CRCs for inode unlinked list

Attempt to reboot the system gracefully when a key combo is detected.
If the reste combination is pressed the 2nd time we assume that graceful
reboot failed and perform emergency reboot. This fucntionality is useful
when UI is stuck but the system is otherwise working fine.

Andy Lutomirski a7526eb5d0 net: Unbreak compat_sys_{send,recv}msg
I broke them in this commit:

    commit 1be374a051
    Author: Andy Lutomirski <luto@amacapital.net>
    Date:   Wed May 22 14:07:44 2013 -0700

        net: Block MSG_CMSG_COMPAT in send(m)msg and recv(m)msg

This patch adds __sys_sendmsg and __sys_sendmsg as common helpers that accept
MSG_CMSG_COMPAT and blocks MSG_CMSG_COMPAT at the syscall entrypoints.  It
also reverts some unnecessary checks in sys_socketcall.

Apparently I was suffering from underscore blindness the first time around.
