glibc and linux-man disagrees about pkey_alloc

[Szabolcs Nagy]

glibc sysdeps/unix/sysv/linux/bits/mman-shared.h:

int pkey_alloc (unsigned int __flags, unsigned int __access_rights) __THROW;

linux-man http://man7.org/linux/man-pages/man2/pkey_alloc.2.html :

int pkey_alloc(unsigned long flags, unsigned long access_rights);

i assume the documentation should be fixed (as the glibc
code is already in use)
