* sh: migrate to arch/sh/include/Paul Mundt2008-07-291-275/+0
| | | | | | | | | | | | | This follows the sparc changes a439fe51a1f8eb087c22dd24d69cebae4a3addac. Most of the moving about was done with Sam's directions at: http://marc.info/?l=linux-sh&m=121724823706062&w=2 with subsequent hacking and fixups entirely my fault.

* sh: Consolidate segment modifiers across mmu/nommu systems.Paul Mundt2008-07-281-4/+0
| | | | | | | | | | This moves get_fs/set_fs() and friends in to asm/segment.h. The mm_segment_t definition is likewise consolidated from the _32/_64 split. This is prepatory groundwork for using the generic address space limit and verification routines across mmu/nommu configs. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Fix occasional FPU register corruption under preempt.Paul Mundt2008-03-261-0/+1
| | | | | | | | | | | 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.

| | | | | | | | | | Move STACK_TOP[_MAX] out of asm/a.out.h and into asm/processor.h as they're required whether or not A.OUT format is available.
