We do our best to keep copyright headers up to date, yet
git history provides better information on this subject
and is more accurate than copyright headers.
* linux/*/get_error.c: Rename all arch-specific implementations
of get_error() to arch_get_error().
* linux/*/get_syscall_args.c: Rename all arch-specific implementations
of get_syscall_args() to arch_get_syscall_args().
* syscall.c (get_syscall_args, get_error): New functions.
(tamper_with_syscall_exiting, get_syscall_result): Do not clear
tcp->u_error before get_error() invocation as the latter does it now.
By very popular demand.
While we are here, let's refactor the condition for old_mmap_pgoff into
an arch-specific one, as it is used more than in one place.
* NEWS: Mention this.
* strace.1.in (.SH "MULTIPLE PERSONALITY SUPPORT"): Likewise.
* configure.ac (case "$host_cpu" in) <s390x>: Set arch_m32 to s390, set
cc_flags_m32 to -m31.
(st_MPERS([m32])): Add s390x.
* defs.h [S390X]: Define NEED_UID16_PARSERS.
* linux/s390/arch_sigreturn.c [!S390_FRAME_PTR] (S390_FRAME_PTR): New
macro, define to s390_frame_ptr.

__SIGNAL_FRAMESIZE.
[!PTR_TYPE] (PTR_TYPE): New macro, define to unsigned long.
(arch_sigreturn): Use S390_FRAME_PTR, SIGNAL_FRAMESIZE, and PTR_TYPE
instead of s390_frame_ptr, __SIGNAL_FRAMESIZE, and pointer-sized type,
respectively.
* linux/s390/get_error.c [!ARCH_REGSET] (ARCH_REGSET): New macro, define
* to s390_regset.
(get_error): Use it instead of s390_regset.

variables.

ARCH_IOVEC_FOR_GETREGSET, ARCH_PC_REG, ARCH_PERSONALITY_0_IOV_SIZE,
ARCH_PERSONALITY_1_IOV_SIZE): New macros.
