This series fixes the setting of tunable values and ranges from within
glibc through the TUNABLE_SET* macros.  The current way will result in
overreads when reading 4 byte values since do_tunable_update_val always
reads an 8 byte value.  This also results in simplification of the
TUNABLE_SET* macros since they no longer need a type to be passed.

Siddhesh Poyarekar (3):
  Fix casts when setting tunable range
  tunables: Remove C type arg from TUNABLE_SET* macros
  x86: Use SIZE_MAX instead of (long int)-1 for tunable range value
