[PATCH 5/8] [SCSI] tgt: Pass pointers to virt_to_page(), notintegers

From: Ben Hutchings
Date: Sun Oct 27 2013 - 17:53:21 EST

Most architectures define virt_to_page() as a macro that casts its
argument such that an argument of type unsigned long will be accepted
without complaint. However, the proper type is void *, and passing
unsigned long results in a warning on MIPS.

Compile-tested only.

If at first you don't succeed, you're doing about average.
