sh: Fixup last users of irq_chip->typename

2009-11-18T01:50:22+00:00

The typename member of struct irq_chip was kept for migration purposes
and is obsolete since more than 2 years. Fix up the leftovers.

sh: unwinder: Fix up invalid PC refetch in dwarf unwinder.

2009-11-06T08:23:33+00:00

The dwarf unwinder presently attempts to provide a sane PC value if none
is provided, however the logic is broken and cases where a previous valid
dwarf frame exists along with a bogus PC value can still proceed. This
fixes up the test and prevents the unwinder from blowing up.

sh: Check for return_to_handler when unwinding the stack

2009-10-26T01:04:56+00:00

When CONFIG_FUNCTION_GRAPH_TRACER is enabled the function graph tracer
may patch return addresses on the stack with the address of
return_to_handler(). This really confuses the DWARF unwinder because it
will try find the caller of return_to_handler(), not the caller of the
real return address.

So teach the DWARF unwinder how to find the real return address whenever
it encounters return_to_handler().

This patch does not cope very well when multiple return addresses on the
stack have been patched. To make it work properly it would require state
to track how many return_to_handler()'s have been seen so that we'd know
where to look in current->curr_ret_stack[]. So for now, instead of
trying to handle this, just moan if more than one return address on the
stack has been patched.

sh: __irq_entry annotate do_IRQ().

2009-10-26T00:58:31+00:00

This adds an __irq_entry annotation for do_IRQ() so that the IRQ
annotation in the function graph tracer works as advertized. We already
have the IRQENTRY section wired up, so this is just a trivial addition
to actually make use of it.

sh: Fix a TRACE_IRQS_OFF typo.

2009-10-14T06:50:28+00:00

The resume_userspace path had TRACE_IRQS_OFF written incorrectly and so
never handled the transition properly. This was fixed once before but
seems to have made it back in the tree. Fix it for good.

sh: Optimize the setup_rt_frame() I-cache flush.

2009-10-14T06:49:45+00:00

This only needs to flush the return code via the legacy path, and just
invalidates uselessly otherwise. This makes the behaviour consistent for
all of the trampoline setup paths.

sh: Populate initial secondary CPU info from boot_cpu_data.

2009-10-14T06:44:12+00:00

The secondary CPU info was seeing corrupted results due to not entering
all of the setup paths taken by the boot CPU. So we just memcpy() the
boot cpu data over directly, and then fix up the per-CPU bits.

sh: Tidy up SMP cpuinfo.

2009-10-14T06:43:52+00:00

Trivial change for cleaning up the cpuinfo pretty printing on SMP, adds a
newline between CPUs.

sh: Use boot_cpu_data for FPU tests in sigcontext paths.

2009-10-14T06:43:41+00:00

We do not want to use smp_processor_id() from these paths, as they trip
preempt BUGs. Switch the test over to the boot cpu directly.
