sh: Simplify kernel_thread_helper() for sh32.

2008-12-22T09:44:44+00:00

This can use the same implementation as sh64, the generated assembly is
the same between the new and old version, so there is not much point in
leaving it open coded in inline assembly.

This is preparatory work for future consolidation of the _32/_64
variants.

sh: Split out the idle loop for reuse between _32/_64 variants.

sh: do not latency trace idle.

2008-12-22T09:43:49+00:00

Description snipped from Steven Rostedt's PPC patch:

    When idle is called, interrupts are blocked, but the idle
    function will still wake up on an interrupt. The problem is
    that the interrupt disabled latency tracer will take this call
    to idle as a latency.

    This patch disables the latency tracing when going into idle.

sh: Tidy up backtrace formatting with kallsyms disabled.

sh: Add a simple code dumper for SUPERH32 show_regs().

2008-12-22T09:43:49+00:00

This implements a simple show_code() that is in turn plugged in to
show_regs() to provide minimal code dumping at the end of the trace.

Built on top of a simple instruction disassembler derived from the
binutils opcode table.

sh: Trivial trace_mark() instrumentation for core events.

2008-09-21T04:56:39+00:00

This implements a few trace points across events that are deemed
interesting. This implements a number of trace points:

	- The page fault handler / TLB miss
	- IPC calls
	- Kernel thread creation

The original LTTng patch had the slow-path instrumented, which
fails to account for the vast majority of events. In general
placing this in the fast-path is not a huge performance hit, as
we don't take page faults for kernel addresses.

The other bits of interest are some of the other trap handlers, as
well as the syscall entry/exit (which is better off being handled
through the tracehook API). Most of the other trap handlers are corner
cases where alternate means of notification exist, so there is little
value in placing extra trace points in these locations.

Based on top of the points provided both by the LTTng instrumentation
patch as well as the patch shipping in the ST-Linux tree, albeit in a
stripped down form.

sh/kernel/ cleanups

2008-07-28T09:10:30+00:00

This patch contains the following cleanups:
- make the following needlessly global code static:
  - cf-enabler.c: cf_init()
  - cpu/clock.c: __clk_enable()
  - cpu/clock.c: __clk_disable()
  - process_32.c: default_idle()
  - time_32.c: struct clocksource_sh
  - timers/timer-tmu.c: struct tmu_timer_ops
- remove the following unused functions (no CONFIG_BLK_DEV_FD on sh):
  - process_{32,64}.c: disable_hlt()
  - process_{32,64}.c: enable_hlt()
