[Mesa-dev] [PATCH] auxilary/os: correct sysctl use in os_get_total_physical_memory()

[Jonathan Gray]

The length argument passed to sysctl was the size of the pointer
not the type.  The result of this is sysctl calls would fail on
32 bit BSD/Mac OS X.

Additionally the wrong pointer was passed as an argument to store
the result of the sysctl call.
