AP4EVB has to reparent PLLC2 to provide a precise HDMI clock, this is only
possible, if PLLC2 hasn't been enabled yet. Since no other driver currently
uses PLLC2 we can safely remove the CLK_ENABLE_ON_INIT flag. This fixes
the "Cannot set PLLC2 parent: -16, 1 users" error message, when trying to
use HDMI on AP4EVB.

Make do_execve() take a const filename pointer so that kernel_execve() compiles
correctly on ARM:
arch/arm/kernel/sys_arm.c:88: warning: passing argument 1 of 'do_execve' discards qualifiers from pointer target type
This also requires the argv and envp arguments to be consted twice, once for
the pointer array and once for the strings the array points to. This is
because do_execve() passes a pointer to the filename (now const) to
copy_strings_kernel(). A simpler alternative would be to cast the filename
pointer in do_execve() when it's passed to copy_strings_kernel().
do_execve() may not change any of the strings it is passed as part of the argv
or envp lists as they are some of them in .rodata, so marking these strings as
const should be fine.
Further kernel_execve() and sys_execve() need to be changed to match.

Commit 5a5f561 (convert OMAP3 PRCM macros to the _SHIFT/_MASK suffixes)
mistakenly removed the check for PER when disabling the IO chain.
During idle, if the PER powerdomain transitions into a lower state
and CORE does not, the IO pad wakeups are not being disabled in
the idle path after they are enabled. This can happen with the
lower C-states when using CPUidle for example.
This patch ensures that the check for disabling IO wakeups also checks
for PER transitions, matching the check done to enable IO wakeups.
Found when debugging PM/CPUidle related problems reported by Ameya
Palande <ameya.palande@nokia.com>. Problems were triggered
particularily on boards with UART2 consoles (n900, Overo) since UART2
is in the PER powerdomain.
Tested on l-o master (omap3_defonfig + CONFIG_CPU_IDLE=y) as well
as with current PM branch. Boards tested: n900, Overo, omap3evm.

sys_accept4() was added in kernel 2.6.28, but ARM was not updated
to include it. The number and types of parameters is such that
no ARM-specific processing is needed, so wiring up sys_accept4()
just requires defining __NR_accept4 and adding a direct call in
the syscall entry table.
Tested with an EABI 2.6.35 kernel and Ulrich Drepper's original
accept4() test program, modified to define __NR_accept4 for ARM.
Using the updated unistd.h also eliminates a warning then building
glibc (2.10.2 and newer) about accept4() being unimplemented.
