sgi-xpc: Use GFP_ATOMIC for kmalloc in atomic context.
xpc_send_activate_IRQ_uv is called from
<-xpc_send_activate_IRQ_part_uv
<-xpc_indicate_partition_disengaged_uv
(xpc_arch_ops.indicate_partition_disengaged)
<-xpc_die_deactivate
<-xpc_system_die
xpc_system_die is registered by atomic_notifier_chain_register,
which indicates xpc_system_die may be called in atomic context.
So the kmalloc in xpc_send_activate_IRQ_uv may be in atomic context.
Use GFP_ATOMIC instead of GFP_KERNEL in kmalloc.
