[PATCH] Add MAP_HUGETLB and MAP_STACK defines for hppa

[Helge Deller]

The attached patch adds some upstream defines like MAP_HUGETLB and MAP_STACK 
in mman.h for the hppa architecture. 

The glibc mman.h header file for the hppa architecture (sysdeps/unix/sysv/linux/hppa/bits/mman.h)
is missing the Linux upstream defines for MAP_HUGETLB, MCL_ONFAULT, MADV_HUGEPAGE, MADV_NOHUGEPAGE,
MADV_DONTDUMP and MADV_DODUMP. Those are added by this patch.

The existing MADV_xxK_PAGES defines were dropped upstream, because they were
originally added many years ago based on a proposed patch for the Linux kernel
which was never applied. So, this patch drops those unneeded defines.

The change closes BZ #19285].

Please install if okay.

Thanks,
Helge
