2009-12-16mm: export stable page flagsWu Fengguang
Rename get_uflags() to stable_page_flags() and make it a global function for use in the hwpoison page flags filter, which need to compare user page flags with the value provided by user space. Also move KPF_* to kernel-page-flags.h for use by user space tools.
