[PATCH 02/12] hyper-v: use GFP_KERNEL for hv_context.hv_numa_map

From: kys
Date: Sun Feb 11 2018 - 19:47:54 EST


From: Jia-Ju Bai <baijiaju1990@xxxxxxxxx>

The kzalloc function is called with GFP_ATOMIC.
But according to driver call graph, it is not in atomic context,
namely no spinlock is held nor in an interrupt handler.

This GFP_ATOMIC is unnecessary, and replace with GFP_KERNEL.
