Subject: [ia64] fix ppoll and pselect syscalls
Message-id: 20090917153358.10812.22682.sendpatchset@prarit.bos.redhat.com
O-Subject: [RHEL5 PATCH] ia64 fix ppoll and pselect syscalls
Bugzilla: 520867
RH-Acked-by: Dean Nelson <dnelson@redhat.com>
RH-Acked-by: Jarod Wilson <jarod@redhat.com>

syscalls for ppoll and pselect were missing from ia64's unistd.h file.  This
resulted in glibc not executing ppoll and pselect on ia64.

Tested by doing

1.  compile reproducer with existing glibc.  Test fails.

2.  apply patch to tree, and install kernel-headers.

3.  rebuild glibc rpms

4.  reinstall glibc rpms

5.  compile reproducer.  Test succeeds:

[root@altix4 tmp]# ./doit
Calling pselect.
Test succeeded.

Successfully compiled and tested by me.

Resolves BZ 520867.
