slab: use new API for remaining command line parameters

Browse source

Use core_param() and __core_param_cb() instead of __setup() or
__setup_param() to improve syntax checking and error messages.

Replace get_option() with kstrtouint(), because:
* the latter accepts a pointer to const char,
* these parameters should not accept ranges,
* error value can be passed directly to parser.

There is one more change apart from the parsing of numeric parameters:
slab_strict_numa parameter name must match exactly. Before this patch the
kernel would silently accept any option that starts with the name as an
undocumented alias.
