2008-05-08 David S. Miller <davem@davemloft.net>
* sysdeps/unix/sysv/linux/sparc/sparc32/setcontext.S: Use
HIDDEN_JUMPTARGET.
* sysdeps/unix/sysv/linux/sparc/sparc32/sysdep.h
(__SYSCALL_CLOBBERS): Remove %g* registers.
* sysdeps/unix/sysv/linux/sparc/sparc64/sysdep.h
(__SYSCALL_CLOBBERS): Likewise.
2008-05-21 Jakub Jelinek <jakub@redhat.com>

HIDDEN_JUMPTARGET for __errno_location call in libc.so.
