We must save and restore r19 in both PIC and non-PIC
situations since the kernel paths that clobber r19
are independent of that PIC-ness of userspace.
In addition we choose r4 as the temporary register over
r3 which is being used by recent gcc's as the frame
pointer.
* sysdeps/unix/sysv/linux/hppa/bits/fcntl.h: Remove all
definitions and declarations that are provided by
<bits/fcntl-linux.h> and include <bits/fcntl-linux.h>.
(__O_PATH): Define.
Updates the hppa-specific pthread.h from the generic version.
After this update the only difference between the generic
version and the hppa version is the footer protected by the
_PTHREAD_H_HPPA_ guard.
Fix a build failure by using __prlimit64 as the internal
function name for the versioned symbol prlimit64. Without
this patch the build system attempts to alias prlimit64
to itself and that is invalid.
All other arches have this in their syscall list. Looks like hppa
is missing it though and breaks one or two apps that try to call it.
