Rename sysctl_init() to sysctl_init_bases() so to reflect exactly what
this is doing.

The only part of proc_dir_entry the code outside of fs/proc
really cares about is PDE(inode)->data. Provide a helper
for that; static inline for now, eventually will be moved
to fs/proc, along with the knowledge of struct proc_dir_entry
layout.

This hooks up the SET/GET_UNALIGN_CTL knobs cribbing the bulk of it from
the PPC and ia64 implementations. The thread flags happen to be the
logical inverse of what the global fault mode is set to, so this works
out pretty cleanly. By default the global fault mode is used, with tasks
now being able to override their own settings via prctl().

Presently the build bails with the following:
CC arch/sh/mm/alignment.o
cc1: warnings being treated as errors
arch/sh/mm/alignment.c: In function 'unaligned_fixups_notify':
arch/sh/mm/alignment.c:69: warning: cast to pointer from integer of different size
arch/sh/mm/alignment.c:74: warning: cast to pointer from integer of different size
make[2]: *** [arch/sh/mm/alignment.o] Error 1
This is due to the fact that regs->pc is always 64-bit, while the pointer size
depends on the ABI. Wrapping through instruction_pointer() takes care of the
appropriate casting for both configurations.

This splits out the unaligned access counters and userspace bits in to
their own generic interface, which will allow them to be wired up on sh64
too.
