You're right - I got the IOMUX tables wrong and thought UART0 pins are
selected unconditionally. But as it turns out TXD1/RXD1 is for UART0
(mxc_uart_device0), TXD2/RXD2 for UART1 (mxc_uart_device1) etc.
Below is a new patch.
Thanks,
Daniel

mx31: correct csi_clk parent (v2)
changes since v1: we now check if the parent configuration bit was
changed since reset and change the parent when needed.
csi_clk parent was defined with ahb_clk. However, according to the
m31 reference manual, it should be serial_pll_clk.
Guennadi always used a 20 MHz clock that was by chance changed to
a 45 MHz that fits in the mt9t031 spec. Now the clocks are computed
and output correctly (measured on oscillo).

This patch solve those two issues. Until now i based my patches to

mxc: emulate GPIO interrupt on both-edges
MXC GPIO controller does not support generation of interrupts on both
edges. Emulate this mode in software by reconfiguring the irq trigger
polarity on each interrupt. This follows an example of
drivers/mfd/asic3.c.

Move dtc and libfdt sources from arch/powerpc/boot to scripts/dtc
The powerpc kernel always requires an Open Firmware like device tree
to supply device information. On systems without OF, this comes from
a flattened device tree blob. This blob is usually generated by dtc,
a tool which compiles a text description of the device tree into the
flattened format used by the kernel. Sometimes, the bootwrapper makes
small changes to the pre-compiled device tree blob (e.g. filling in
the size of RAM). To do this it uses the libfdt library.
Because these are only used on powerpc, the code for both these tools
is included under arch/powerpc/boot (these were imported and are
periodically updated from the upstream dtc tree).
However, the microblaze architecture, currently being prepared for
merging to mainline also uses dtc to produce device tree blobs. A few
other archs have also mentioned some interest in using dtc.
Therefore, this patch moves dtc and libfdt from arch/powerpc into
scripts, where it can be used by any architecture.
The vast bulk of this patch is a literal move, the rest is adjusting
the various Makefiles to use dtc and libfdt correctly from their new
locations.

vmscan: avoid multiplication overflow in shrink_zone()
Local variable `scan' can overflow on zones which are larger than
(2G * 4k) / 100 = 80GB.
Making it 64-bit on 64-bit will fix that up.

kernel-doc: restrict syntax for private: and public:
scripts/kernel-doc can (incorrectly) delete struct members that are
surrounded by /* ... */ <struct members> /* ... */ if there is a /*

Fix that by making the "/* private:" only allow whitespace between /* and

Because NR_CPUS can be greater than 1000 and meminfo_proc_show() does
not check for underflow.
But NR_CPUS proportional isn't good calculation. In general,
possibility of lock contention is proportional to the number of online
cpus, not theorical maximum cpus (NR_CPUS).
The current kernel has generic percpu-counter stuff. using it is right
way. it makes code simplify and percpu_counter_read_positive() don't
make underflow issue.

of: make of_(un)register_platform_driver common code
Some drivers using of_register_platform_driver() wrapper break on sparc
because the wrapper isn't in the header file. This patch moves it from

alpha: binfmt_aout fix
This fixes the problem introduced by commit
3bfacef412 (get rid of
special-casing the /sbin/loader on alpha): osf/1 ecoff binary segfaults
when binfmt_aout built as module. That happens because aout binary
handler gets on the top of the binfmt list due to late registration, and
kernel attempts to execute the binary without preparatory work that must
be done by binfmt_loader.
Fixed by changing the registration order of the default binfmt handlers
using list_add_tail() and introducing insert_binfmt() function which
places new handler on the top of the binfmt list. This might be generally
useful for installing arch-specific frontends for default handlers or just
for overriding them.
