sparc,sparc64: unify kernel/

2008-12-04T17:17:21+00:00

o Move all files from sparc64/kernel/ to sparc/kernel
  - rename as appropriate
o Update sparc/Makefile to the changes
o Update sparc/kernel/Makefile to include the sparc64 files

NOTE: This commit changes link order on sparc64!

Link order had to change for either of sparc32 and sparc64.
And assuming sparc64 see more testing than sparc32 change link
order on sparc64 where issues will be caught faster.

sparc64: Fix sparse warnings in global reg snapshotting.

2008-09-12T06:19:22+00:00

Lots of shadowed local variables and global_reg_snapshot[] needs
an extern declaration in asm/ptrace_64.h.

sparc64: Move reboot handling into seperate file and kill power reg programming.

2008-09-02T07:31:11+00:00

We should always use prom_power_off().

sparc64: Kill __show_regs().

2008-08-01T03:33:43+00:00

The story is that what we used to do when we actually used
smp_report_regs() is that if you specifically only wanted to have the
current cpu's registers dumped you would call "__show_regs()"
otherwise you would call show_regs() which also invoked
smp_report_regs().

Now that we killed off smp_report_regs() there is no longer any
reason to have these two routines, just show_regs() is sufficient.

Also kill off a stray declaration of show_regs() in sparc64_ksym.c

sparc64: Kill smp_report_regs().

2008-07-31T08:06:02+00:00

All the call sites are #if 0'd out and we have a much more
useful global cpu dumping facility these days.  smp_report_regs()
is way too verbose to be usable.

sparc64: Kill VERBOSE_SHOWREGS code.

2008-07-31T07:58:35+00:00

It just clutters everything up and even though I wrote that hack I
can't remember having used it in the last 5 years or so.

sparc64: Hook up trigger_all_cpu_backtrace().

2008-07-31T05:35:00+00:00

We already have code that does this, but it is only currently attached
to sysrq-'y'.

sparc64: Make global reg dumping even more useful.

2008-07-31T04:57:59+00:00

Record one more level of stack frame program counter.

Particularly when lockdep and all sorts of spinlock debugging is
enabled, figuring out the caller of spin_lock() is difficult when the
cpu is stuck on the lock.

sparc64: Fix global reg snapshotting on self-cpu.

2008-07-28T07:44:29+00:00

We were picking %i7 out of the wrong register window
stack slot.
