	sparc64: Log warning for invalid hugepages boot param
Removes "#include <linux/dtrace_os.h>" from arch/sparc/mm/fault_64.c.

The topic/uek-4.1/sparc code base has:
    #include <linux/context_tracking.h>
    #include <linux/hugetlb.h>
    #include <linux/dtrace_os.h>

v4.1.12-46 has:
    #include <linux/context_tracking.h>
    #include <linux/dtrace_os.h>

Remove "#include <linux/hugetlb.h>" so that bd52d0fd57 will merge with
v4.1.12-46.
