According to arch/arm/kernel/sys_oabi-compat.c,
struct statfs64 has extra padding with EABI.
* statfs.c [AARCH64 || defined ARM] (COMPAT_STATFS64_PADDED_SIZE):
Define.
(do_statfs64_fstatfs64): New function, factored out from sys_statfs64.
[COMPAT_STATFS64_PADDED_SIZE]: Check it in addition to
sizeof(struct compat_statfs64).
(sys_statfs64, sys_fstatfs64): Use do_statfs64_fstatfs64.

Newer architectures have no chown syscall, so use fchown* syscalls
for testing printuid.

of __NR_chown and __NR_chown32.

Newer architectures have no stat syscall, so stat() is implemented there
using newfstatat syscall.
* tests/stat.c (STAT_FNAME): Rename to STAT_PREFIX. Update callers.
[_FILE_OFFSET_BITS == 64] (STAT_PREFIX): Add newfstatat support.
(main) [!NR_stat]: Add newfstatat support.

STRUCT_STAT.st_[acm]time are declared as unsigned int for some
personalities, while time_t is signed.
* printstat.h (DO_PRINTSTAT): If st_[acm]time have the same size as int,
explicitly cast them to int.
* tests/stat64-v.test: Test that negative time_t is decoded properly.

On architectures where the semctl call is implemented by the ipc syscall
the 4th argument is passed by reference.
* ipc.c (sys_semctl): Handle the indirect ipc subcall case.
* tests/ipc_sem.c (main): Optionally match indirection
in the 4th argument of semctl calls.
Reported-by: Andreas Schwab <schwab@suse.de>
* tests/ipc_msg.c (main): Optionally match "IPC_64|" in the third
argument of the ipc call.
* tests/ipc_sem.c (main): Likewise.
* tests/ipc_shm.c (main): Likewise.
Properly use union semun as argument of semctl.
* tests/ipc_sem.c (main): Properly use union semun as argument of
semctl. Don't handle EFAULT specially.
* tests/ipc_sem.test: Revert last change.
* linux/aarch64/ioctls_inc0.h: Rename from ioctls_inc1.h.
* linux/aarch64/ioctls_inc1.h: Rename from ioctls_inc0.h.

* signal.c (sprintsigmask_n): Make global.
(tprintsigmask_addr): Remove.
(sys_sigreturn): Move to sigreturn.c.
Implement additional synchronization between parent and child processes
to guarantee that the child starts closing connected socket only after
exiting of the parent's accept() syscall.
This guarantee seems to be necessary to reliably receive UNIX_DIAG_PEER
messages from NETLINK_SOCK_DIAG interface.
* tests/net-accept-connect.c: Implement additional synchronization
between parent and child processes.
* tests/unix-yy-connect.awk: Update.
* configure.ac (ASM_SIGRTMIN): Define to SIGRTMIN from <asm/signal.h>.
* signal.c: Use ASM_SIGRTMIN instead of constants provided by libc.
* tests/sigreturn.c: Use ASM_SIGRTMIN instead of hardcoded value.
Use lower RT_* numbers to support pre-3.18 hppa kernels.
* tests/sigreturn.test: Update regexp.

mask on 32bit personality.
Fix compilation warnings introduced by commit
5b9b7e1d34:
signal.c:702:45: warning: signed and unsigned type in conditional expression [-Wsign-compare]
syscall.c:746:34: warning: initialization from incompatible pointer type [enabled by default]
* syscall.c [AARCH64] (aarch64_sp_ptr): Add explicit cast.

Although sigreturn takes signal mask via frame pointer,
it's more convenient to display signal mask as a syscall argument
rather than an outstanding object of unknown nature:
Before this change:
sigreturn() (mask [USR2 CHLD RT_2 RT_3 RT_4 RT_31 RT_32]) = 0
After this change:
sigreturn({mask=[USR2 CHLD RT_2 RT_3 RT_4 RT_31 RT_32]}) = 0
* signal.c (sys_sigreturn): Display signal mask as a syscall argument.
* linux/64/syscallent.h (139): Use sys_sigreturn for rt_sigreturn
decoding.
* syscall.c [ARM] (arm_regs): Make static.
[ARM] (arm_sp_ptr): New variable.
[AARCH64] (aarch64_sp_ptr, arm_sp_ptr): New variables.
* linux/aarch64/arch_regs.h: New file.
* linux/arm/arch_regs.h (arm_regs): Remove.
(arm_sp_ptr): New declaration.
* signal.c (sys_sigreturn) [ARM]: Use arm_sp_ptr.
[AARCH64]: Print signal mask.
Without this users might get confused why `man strace` describes
an option that doesn't work.
* strace.1: Note that -k is available only if strace is built
with libunwind.
* debian/control (strace, strace-udeb): Add mips64 and mips64el
to architecture list.
Patch by James Cowgill <james410@cowgill.org.uk>
This fixes Debian bug #773375.
In mips n32 abi, like in most of 32-bit architectures, offset
is passed to preadv/pwritev syscalls using two syscall arguments.
* io.c (print_llu_from_low_high_val) [LINUX_MIPSN32]: Remove.
Rather than trigger an ERROR which fails `make check`, go with SKIP
instead. We don't want the testsuite failing due to kernel bugs.
* tests/ipc_sem.c (main): Change 99 to 77.
