Merge tag 'pull-headers_param' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

Pull asm/param cleanup from Al Viro:
 "This massages asm/param.h to simpler and more uniform shape:

   - all arch/*/include/uapi/asm/param.h are either generated includes
     of <asm-generic/param.h> or a #define or two followed by such
     include

   - no arch/*/include/asm/param.h anywhere, generated or not

   - include <asm/param.h> resolves to arch/*/include/uapi/asm/param.h
     of the architecture in question (or that of host in case of uml)

   - include/asm-generic/param.h pulls uapi/asm-generic/param.h and
     deals with USER_HZ, CLOCKS_PER_SEC and with HZ redefinition after
     that"

* tag 'pull-headers_param' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
