Presently with preempt enabled there's the possibility to be preempted
after the TIF_USEDFPU test and the register save, leading to bogus
state post-__switch_to(). Use an explicit preempt_disable()/enable()
pair around unlazy_fpu()/clear_fpu() to avoid this. Follows the x86
change.

Presently the SH-2/SH-2A address error exception dispatch copies off the
register state from the stack and skips over the first register, skewing
the rest. Fix up the math here so that the proper register state is
handed down to the exception handler itself.

This header is needed on other architectures as well (namely h8300),
which currently fails to build without this in place. Rather than
duplicating the port definition completely there, just move this to a
common location instead.

This should get h8300 working again for 2.6.25, in addition to the
changes already pushed by Sato-san in -rc2.

The C99 specification states in section 6.11.5:

The placement of a storage-class specifier other than at the
beginning of the declaration specifiers in a declaration is an
obsolescent feature.
