Subject: RDMA/mthca: Make explicit conversion to 64bit value
Patch-mainline: v4.14-rc1
Git-commit: 623248955d985b86cd778c63efe6a7ad03a018c4
References: bsc#1046306 FATE#322942

The "lg" variable is declared as int so in all places where
this variable is used as a shift operand, the output will be
int too.

This produces the following smatch warning:
drivers/infiniband/hw/mthca/mthca_cmd.c:701 mthca_map_cmd() warn:
	should '1 << lg' be a 64 bit type?

Simple declaration of "1" to be "1ULL" will fix the issue.
