On LP64 systems, reading a sysctl file containing an INT_MIN (-2147483648)
could incorrectly show -18446744071562067968 due to an incorrect conversion
in do_proc_dointvec_conv. This patch fixes the edge case by converting to
unsigned int first to avoid sign extending INT_MIN to unsigned long.

On LP64 systems, reading a sysctl file containing an INT_MIN (-2147483648)
could incorrectly show -18446744071562067968 due to an incorrect conversion
in do_proc_dointvec_conv. This patch fixes the edge case by converting to
unsigned int first to avoid sign extending INT_MIN to unsigned long.
