The big kernel lock has been removed from all these files at some point,
leaving only the #include.

Remove this too as a cleanup.

According to commit 5e3d20a68f63fc5a310687d81956c3b96e488b84
(init: Remove the BKL from startup code) these sparse notations
should be removed also.

early_init_irq_lock_class() is called way before anything touches the
irq descriptors. In case of SPARSE_IRQ=y this is a NOP operation
because the radix tree is empty at this point. For the SPARSE_IRQ=n
case it's sufficient to set the lock class in early_init_irq().

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.

This has been test built on x86_64, frv, arm and mips.

Since this section can be read-only (they're in .rodata), they should
always have been const.  Minor flow-through various functions.

Andrew Morton suggested that the do_one_initcall and do_one_initcall_debug
functions can be marked __init_or_module such that they can be discarded
for the CONFIG_MODULES=N case.

Using:

	gcc (GCC) 4.5.0 20100610 (prerelease)

The following warning appears:

	init/main.c: In function `do_one_initcall':
	init/main.c:730:10: warning: `calltime.tv64' may be used uninitialized in this function

This warning is actually correct, as the global initcall_debug could
arguably be changed by the initcall.

Correct this warning by extracting a new function, do_one_initcall_debug,
that performs the initcall for the debug case.
