[PATCH v4] flexcan: add err_irq handler for flexcan

2014-07-01 Thread Zhao Qiang
when flexcan is not physically linked, command 'cantest' will trigger an err_irq, add err_irq handler for it. Signed-off-by: Zhao Qiang --- Changes for v2: - use a space instead of tab - use flexcan_poll_state instead of print Changes for v3: - return IRQ_HANDLED if err is

[PATCH v2] powerpc/kvm: support to handle sw breakpoint

2014-07-01 Thread Madhavan Srinivasan

Patch also adds support for software breakpo
