glibc/sysdeps/mach/getsysstats.c
Roland McGrath 9ce8b3c817 * hurd/Versions (libc: GLIBC_2.0): Add _S_catch_exception_raise_state,
_S_catch_exception_raise_state_identity,
	_hurdsig_fault_catch_exception_raise_state,
	_hurdsig_fault_catch_exception_raise_state_identity.

	* mach/shortcut.awk: Don't apply the /^}$/ rule when $proto == "".

	* sysdeps/mach/getsysstats.c (__get_avphys_pages) [HOST_VM_INFO]: Use
	__host_info with HOST_VM_INFO flavor instead of __vm_statistics.

	* sysdeps/mach/hurd/getpriority.c [TASK_SCHED_TIMESHARE_INFO]: Find
	`base_priority' in PIP->timeshare_base_info instead of PIP->taskinfo.

	* sysdeps/mach/hurd/dl-sysdep.c [FMH]: Define for i386 only.
	(fmh, unfmh): Define these functions only #if FMH.  Otherwise define
	them as no-op macros.
	[FMH] (ELF_MACHINE_USER_ADDRESS_MASK): Redefine it to zero.
	(__mmap): Uncomment uses of ELF_MACHINE_USER_ADDRESS_MASK.

	* sysdeps/powerpc/dl-machine.h
	(ELF_MACHINE_USER_ADDRESS_MASK): New macro.
