The spinlock in traps_64.c is used without initialization.
This fixes it by declaring DEFINE_SPINLOCK() and makes the spinlock static
variable.

This is needed to fix up the build at the moment. Gradually this will be
reworked to follow the 32-bit initialization path and deal with delayed
VBR initialization.

This updates the sh64 processor info with the sh32 changes in order to
tie in to the generic task_xstate management code.

After the recent FPU optimisation commit the signature of save_fpu()
changed. "regs" wasn't used in the implementation of save_fpu() anyway.

For consistency drop & in front of every proc_handler. Explicity
taking the address is unnecessary and it prevents optimizations
like stubbing the proc_handlers to NULL.

Now that sys_sysctl is a generic wrapper around /proc/sys .ctl_name
and .strategy members of sysctl tables are dead code. Remove them.
Also add an C99 named initializer to the child member of unaligned_root
to prevent chaos as the ctl_table definition changes over time.

sh64 has traditionally had this configurable via a Kconfig option
(CONFIG_SH64_USER_MISALIGNED_FIXUP). In practice it has never really been
terribly useful to turn this off, so just get rid of the option entirely.
We leave the sysctl around so we don't end up breaking existing root
file systems, and to allow folks that really want this off to do so at
their own risk.

This patch fixes some compile errors due to missing save_fpu()
prototypes on sh64 caused by

(sh: Fix occasional FPU register corruption under preempt).
