From: Thierry Reding <treding@nvidia.com>
The nasid_to_try variable is an array of integers, so plain integers can be used when assigning values to the elements rather than casting a NULL pointer to an integer, which results in the following warning from GCC:
arch/ia64/sn/kernel/bte.c:117:22: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] nasid_to_try[1] = (int)NULL; ^ arch/ia64/sn/kernel/bte.c:125:22: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] nasid_to_try[1] = (int)NULL; ^
Replace (int)NULL with a simple 0 to silence these warnings.
