* sysdeps/hppa/dl-machine.h (elf_machine_fixup_plt): Remove
	lvalue cast.
	* sysdeps/hppa/dl-trampoline.S (_dl_fixup): Correct stack usage.
	(_dl_runtime_profile): LA fixups.
	* sysdeps/unix/sysv/linux/hppa/clone.S: Correct stack usage. Return
	-1 on error. Use branch and link for error handler funciton.
	* sysdeps/unix/sysv/linux/hppa/sysdep.h: Correct stack usage.
	Avoid register shuffling.
	* sysdeps/unix/sysv/linux/hppa/bits/atomic.h (ASM_EAGAIN): Define
	as -EAGAIN.
	* sysdeps/unix/sysv/linux/hppa/bits/mman.h: Adjust definitions to
	match required standards.
	* sysdeps/unix/sysv/linux/hppa/nptl/lowlevellock.h
	(lll_futex_wait): Return __ret.
	(lll_futex_timed_wait): Likewise.
	(lll_futex_wake): Likewise.
	(lll_futex_requeue): Likewise.
	* sysdeps/unix/sysv/linux/hppa/nptl/pt-vfork.S: Correct stack
	usage and adjust error return.
	* sysdeps/unix/sysv/linux/hppa/nptl/sysdep-cancel.h: Adjust
	stack usage for gdb, and avoid extra register loads.
	* sysdeps/unix/sysv/linux/hppa/nptl/unwind-forcedunwind.c: Copy
	nptl/sysdeps/pthread/unwind-forcedunwind.c.
	(LIBGCC_SO): Define and use.
	* sysdeps/unix/sysv/linux/hppa/nptl/unwind-resume.c: Copy
	nptl/sysdeps/pthread/unwind-resume.c.
	(LIBGCC_SO): Define and use.
