[PATCH] grant-table: don't set m2p override if kmap_ops is not set

2013-11-05 Thread Roger Pau Monne
IMHO there's no reason to set a m2p override if the mapping is done in kernel space, so only set the m2p override when kmap_ops is set. When kmap_ops is not set, just set the correct p2m translation, this avoids touching the m2p lock, reducing contention around it. Signed-off-by: Roger Pau Monné
