sh: Tidy up NEFF-based sign extension for SH-5.

2009-08-04T08:14:39+00:00

This consolidates all of the NEFF-based sign extension for SH-5.
In the future the other SH code will need to make use of this as well,
so make it generic in preparation for more 32/64 consolidation.

ptrace: remove PT_DTRACE from avr32, mn10300, parisc, s390, sh, xtensa

2009-06-18T20:03:48+00:00

avr32, mn10300, parisc, s390, sh, xtensa:

They never set PT_DTRACE, but clear it after do_execve().

sh: remove stray markers.

2009-06-18T04:38:26+00:00

arch/sh has a couple of stray markers without any users introduced
in commit 3d58695edbfac785161bf282dc11fd42a483d6c9.  Remove them in
preparation of removing the markers in favour of the TRACE_EVENT
macro (and also because we don't keep dead code around).

sh: Drop the BKL from sys_execve() on SH-5.

2009-01-21T08:42:55+00:00

Brings it in line with the SH implementation, the BKL is not
necessary here.

sh: Convert sh64 /proc/asids to debugfs and generic sh.

2008-12-22T09:44:03+00:00

This converts the sh64 /proc/asids entry to debugfs and enables it for
all SH parts that have debugfs enabled.

On MMU systems this can be used to determine which processes are using
which ASIDs which in turn can be used for finer grained cache tag
analysis.

sh: Kill off sh64's unused alloc/free_task_struct() definitions.

2008-12-22T09:44:03+00:00

These were left over from some time ago, sh64 never got around to
defining __HAVE_ARCH_TASK_STRUCT_ALLOCATOR during the conversion, and it
has no need to. Kill these off and use the generic versions instead.

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.
