Ryan Stone f2c2231e0c Fix integer truncation bug in malloc(9)
A couple of internal functions used by malloc(9) and uma truncated
a size_t down to an int.  This could cause any number of issues
(e.g. indefinite sleeps, memory corruption) if any kernel
subsystem tried to allocate 2GB or more through malloc.  zfs would
attempt such an allocation when run on a system with 2TB or more
of RAM.

Note to self: When this is MFCed, sparc64 needs the same fix.
