tools/mm/page-types: fix typo in madvise() error message

Browse Source 
Patch series "tools/mm/page-types: Fix misc bugs".

This series fixes three issues in tools/mm/page-types.c:

1. Fix two typos in madvise() error messages ("madvice" -> "madvise")
2. Fix operator precedence bug in the sigbus handler where the ternary
   operator binds looser than addition, producing incorrect offset
   calculation when sigbus_addr is non-NULL
3. Fix --kpageflags option declaration in getopt_long: has_arg should
   be 1 (required_argument) since the option requires a file path


This patch (of 3):

Two error messages incorrectly spelled the madvise() function name as
"madvice".  Fix the typo in both occurrences.
