sh: Rework irqflags tracing to fix up CONFIG_PROVE_LOCKING.

2009-07-29T14:01:24+00:00

This cleans up the irqflags tracing code quite a bit and ties it
in to various missing callsites that caused an imbalance when
CONFIG_PROVE_LOCKING was enabled.

Previously this was catching on:

 987 #ifdef CONFIG_PROVE_LOCKING
 988     DEBUG_LOCKS_WARN_ON(!p->hardirqs_enabled);
 989     DEBUG_LOCKS_WARN_ON(!p->softirqs_enabled);
 990 #endif
 991     retval = -EAGAIN;

with hardirqs being doubly enabled, and subsequently bailing out
with the following call trace:

	Call trace:

	[<88015a8c>] do_fork+0xf8/0x2b0

sh-sci: update receive error handling for muxed irqs

2009-07-03T08:45:58+00:00

This patch updates the receive error code for muxed
interrupts in the sh-sci driver.

Receive error interrupts may be generated by the hardware
if RE or REIE bits in SCSCR are set. Update the muxed
interrupt handling code to acknowledge error interrupts
if RE or REIE is set, instead of only acknowledging if
REIE is set.

Without this patch error interrupts may be generated but
never acked resulting in a "nobody cared" crash.
