[PATCH v10 10/17] powerpc/64: Rename soft_enabled to irq_soft_mask
Madhavan Srinivasan
maddy at linux.vnet.ibm.com
Wed Dec 20 14:55:50 AEDT 2017
Rename the paca->soft_enabled to paca->irq_soft_mask as it is no
longer used as a flag for interrupt state, but a mask.
Signed-off-by: Madhavan Srinivasan <maddy at linux.vnet.ibm.com>
