hyper-v: use GFP_KERNEL for hv_context.hv_numa_map
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. Signed-off-by: Jia-Ju Bai <baijiaju1990@gmail.com> Reviewed-by: Vitaly Kuznetsov <vkuznets@redhat.com> Signed-off-by: K. Y.
