fe25591e7b SH4: Privilege check for instructions
This patch adds check for all SH4 instructions which are
executed only in privileged mode.

f24f381b2d SH4: sleep instruction bug fix
fix a bug on 'sleep' instruction, which have caused halt of idle task.
As i386 'hlt' instruction does, it should save PC before sleep.

0fd3ca30c4 sh4: CPU versioning.
Trivial patch adding CPU listing and the ability to do per-subtype
CVR/PVR/PRR values. Presently SH7750R and SH7751R definitions are
provided, as these are the ones in present use in-tree.

The CVR value for SH7751R is intentionally restricted so the kernel
boots, though this will want to be switched to the proper CVR value
once system emulation has sufficiently stabilized.

This also makes it trivial to abstract subtype specific registers like
MMU_PTEA and to set up feature bits in line with the kernel probing for
things like conditionalizing FPU/DSP context.

7da76bcef2 [sh4] code translation bug fix
When a TLB miss occurs while pre-decrement store instruction such as
"mov.l Rm, @-Rn" is executed, re-execution of such instruction cause
status confusion. Because pre Rn decrement is executed before TLB miss,
re-execution decrements Rn again.
In other words, in a translated instruction array, register status
should not modified before memory access instruction.

274a9e70de [sh4] delay slot bug fix
Two bugs about delay slot handlings are fixed.

- After an exception occurred in delay slot, the branch instruction
  before delay slot should be executed again. To judge such re-execution
  is necessery or not, delay slot status is kept in SH4 CPU data structure.
- When a branch instruction is placed at the end of memory segment,
  the delay slot is placed at the start of next memory segment.
  It means delay slot comes to the start of a translation block.
  In such occasion, DELAY_SLOT_CLAREME flag is used to transmit status
  between translation blocks. When an exception occurs on this kind of
  delay slot, DELAY_SLOT_CLEARME flag cause a status confusion in exception
  handling. DELAY_SLOT_CLEARME flag should be cleared on exceptions.

And some items are added to CPU status dump.
