Matt Fleming 70fe224743 sh: Enable GENERIC_HARDIRQS_NO__DO_IRQ for all SuperH machines
After the recent changes to switch SuperH board support over to irq_chip
it is now possible to set GENERIC_HARDIRQS_NO__DO_IRQ for all SuperH
boards.

Matt Fleming 1a94757fae sh: Convert Cayman boards from hw_interrupt_type to irq_chip
I've been unable to even compile-test this change because I don't have
an sh5 toolchain. All uses of hw_interrupt_type for SuperH boards have
now been converted to use irq_chip.

Matt Fleming e85a47744b sh: Convert Dreamcast support from hw_interrupt_type to irq_chip
Switch the dreamcast IRQ code over to the irq_chip way of doing things,
so that we can set GENERIC_HARDIRQS_NO__DO_IRQ for all SuperH boards.

Also, whilst I'm here change some things to make checkpatch.pl happy:
	- Indent with tabs, not with spaces
	- Include <linux/io.h>, not <asm/io.h>
	- Fix the multi-line comment style
	- Fix some typos in the comments

Takashi YOSHII 3b041227f7 sh: Add plain udivsi3 (not _i4*) for gcc-4.1 and lower.
We chan't share code for udivsi3 and udivsi3_i4, because they
have a different clobber list. Copy udivsi3 from gcc-4.1.2.

As shown in arch/sh/lib/udivsi3.S (and -Os.S),

  .global __udivsi3_i4i
  .global __udivsi3_i4
  .global __udivsi3
__udivsi3_i4i:
  ...

Three symbols are sharing one code, which is actually udivsi3_i4i.
But, this results unwanted code with gcc 4.1.

In gcc, these three are treated as pseudo instructions that have
their own clobber list apart from the usual calling convention.

According to sh's machine description. The clobber list is as
follows:

 - udivsi3_i4i : t,r1,pr,mach,macl
 - udivsi3_i4  : t,r0,r1,r4,r5,pr,dr0,dr2,dr4
 - udivsi3     : t,r4,pr

The caller of udivsi3 will be left with a broken r1 and mac*.

gcc-4.1.x and older(at least to 3.4) generate udivsi3.
ST's gcc-4.1.1 seems to be OK because it has _i4i.
