08932d8196 ep93xx: Configure GPIO ports in core code
Move the pinmux setting of the EP93xx GPIOs to the core code. This
removes the need for the GPIO driver to have access to the system
controller registers.

a05baf335b ep93xx: Move peripheral defines to local SoC header
Move the AHB/APB peripheral defines to local SoC header since they are
only needed by the core SoC code. The UART defines are not moved
because they are used by the mach/uncompress.h header.

0fd1958050 ep93xx: Use ioremap for backlight driver
The ep93xx backlight driver uses a single register within the
framebuffer's register space. Currently the backlight driver uses a
static IO mapping for the register since the memory cannot be
requested by both drivers.

Convert the static mapping to use ioremap so that we can remove the
dependency on mach/hardware.h. To do so, we need remove the
request_mem_region from both the backlight and framebuffer drivers,
since whichever driver is loaded second will fail with -EBUSY
otherwise.

A proper fix is still required, and a FIXME comment has been added to
both drivers.

From Tony Lindgren:

"Here's one more kernel panic fix that I dropped from last weeks
fixes as it was still being discussed.

This is a fix for the regression caused by fixing an earlier
regression for smsc911x fixed regulators :(

Turns out that we have more than one smsc911x on some boards,
and the earlier fix causes a kernel panic for board trying to
register second smsc911x instance, even if the second smsc911x
is on an add-on board that is not connected.

Note that the boards with second smsc911x will also need to be
patched later on to provide their own regulators."

ad09233835 tile: Use set_current_blocked() and block_sigmask()
As described in e6fa16ab ("signal: sigprocmask() should do
retarget_shared_pending()") the modification of current->blocked is
incorrect as we need to check whether the signal we're about to block
is pending in the shared queue.

Also, use the new helper function introduced in commit 5e6292c0f2
("signal: add block_sigmask() for adding sigmask to current->blocked")
which centralises the code for updating current->blocked after
successfully delivering a signal and reduces the amount of duplicate
code across architectures. In the past some architectures got this
code wrong, so using this helper function should stop that from
happening again.

9993bc635d sched/x86: Fix overflow in cyc2ns_offset
When a machine boots up, the TSC generally gets reset.  However,
when kexec is used to boot into a kernel, the TSC value would be
carried over from the previous kernel.  The computation of
cycns_offset in set_cyc2ns_scale is prone to an overflow, if the
machine has been up more than 208 days prior to the kexec.  The
overflow happens when we multiply *scale, even though there is
enough room to store the final answer.

We fix this issue by decomposing tsc_now into the quotient and
remainder of division by CYC2NS_SCALE_FACTOR and then performing
the multiplication separately on the two components.

Refactor code to share the calculation with the previous
fix in __cycles_2_ns().

81e46f7b6d ARM: smp_twd: add runtime registration support
Add support for the new registration interface to smp_twd.
Platforms can populate a struct twd_local_timer with MMIO
and IRQ resources, and then call twd_local_timer_register()
to have the timer registered with the core.

0ef330e10d ARM: local timers: introduce a new registration interface
In order to switch to a runtime selectable local timer,
add a registration interface that timer drivers can use to
register to the core.

local_timer_setup() and local_timer_stop() are made weak symbols
in order not to break existing setups.

abde710ca8 ARM: smp_twd: make local_timer_stop a symbol instead of a #define
When CONFIG_HAVE_ARM_TWD is selected, local_timer_stop is a #define,
while all other local timers are using a real function.

Convert it to an alias of twd_timer_stop, as it helps converting
all local timers to another internal API in a sane way.

1dde9f75b6 iomux-mx25.h slew rate adjusted for LCD __LD pins
For some reason (sadly i don't identifying the patch right now)
two LCD data lines configured PAD_CTL_SRE_SLOW (wrong slew rate)
since Kernel 3.1. MX25_PAD_GPIO_E__LD16 and MX25_PAD_GPIO_F__LD17
This results in an fauly behaviour and strange color effects.

To ensure that all LCD data pins configured with the proper slew rate,
this patch changes to IOMUX define of all LCD __LDxx pins to PAD_CTL_SRE_FAST.

This problem may affect other mx25 platforms like mx25pdk. Sadly i can't test
it. Of course this problem shouldn't occur when you done your LCD muxing
correctly in the bootloader.

Best regards,
Torsten
