sh: Fix up DSP context save/restore.

2009-04-04T15:48:11+00:00

There were a number of issues with the DSP context save/restore code,
mostly left-over relics from when it was introduced on SH3-DSP with
little follow-up testing, resulting in things like task_pt_dspregs()
referencing incorrect state on the stack.

This follows the MIPS convention of tracking the DSP state in the
thread_struct and handling the state save/restore in switch_to() and
finish_arch_switch() respectively. The regset interface is also updated,
which allows us to finally be rid of task_pt_dspregs() and the special
cased task_pt_regs().

sh: hibernation support

2009-03-10T03:55:40+00:00

Add Suspend-to-disk / swsusp / CONFIG_HIBERNATION support
to the SuperH architecture.

To suspend, use "swapon /dev/sda2; echo disk > /sys/power/state"
To resume, pass "resume=/dev/sda2" on the kernel command line.

The patch "pm: rework includes, remove arch ifdefs V2" is
needed to allow the generic swsusp code to build properly.

Hibernation is not enabled with this patch though, a patch
setting ARCH_HIBERNATION_POSSIBLE will be submitted later.

sh: Fix up SH-X3 general exception handler build.

2009-02-27T08:02:28+00:00

With the recent entry.S refactoring, the SH-X3 path had a mov.l for a
register to register copy, resulting in:

  AS      arch/sh/kernel/cpu/sh4/../sh3/entry.o
arch/sh/kernel/cpu/sh4/../sh3/entry.S: Assembler messages:
arch/sh/kernel/cpu/sh4/../sh3/entry.S:366: Error: invalid operands for opcode
make[3]: *** [arch/sh/kernel/cpu/sh4/../sh3/entry.o] Error 1

Switch it over to a mov to fix it up.

sh: prefetch early exception data on sh4/sh4a.

2009-02-27T07:41:17+00:00

Prefetch early exception data. There is unused space in our
exception handler cache line anyway, so this is almost free.

sh: remove EXPEVT vector from stack on sh3/sh4/sh4a

2009-02-27T07:26:19+00:00

Remove EXPEVT vector from the stack, lookup_exception_vector()
for sh3/sh4/sh4a is already using k2 to get the vector.
