Subject: [PATCH v5 0/4] arm64: prerequisites for audit and ftrace

This patchset contains some patches commonly applied for audit and ftrace.

Patch [1/4] defines syscall trace related TIF_* flags in order to add hooks,
including ftrace, audit and seccomp, later on.  Those features will be
implemented in separate patchsets, but it's safe to check for all TIF_*
now because they can not be turned on anyway.

Patch [2/4] doesn't change a behavior but make it easy and manageable to
confirm we invoke those hooks in correct order by splitting syscall_trace().

Patch [3/4] adds a commonly used function, which returns a return value of
system call.

Patch [4/4] removes is_compat_task from asm/compat.h to avoid conflicted
definitions.

Changes v4 -> v5:
* added the following patch from my seccomp patch since it is required for
  audit and ftrace in case of !COMPAT, too. [4/4]
  "arm64: is_compat_task is defined both in asm/compat.h and linux/compat.h"

Changes v3 -> v4:
* added "arm64: split syscall_trace() into separate functions for enter/
  exit", which is just a preparation for adding syscall trace hooks later.

Changes v2 -> v3:
* reverted a change in syscall_trace() in v1 [1/2]
* added "arm64: Add regs_return_value() in syscall.h" patch which was
  previously included in audit patch [2/2]

Changes v1 -> v2:
* added a guard against TIF_SYSCALL_TRACE at tracehook_report_syscall_*()
* renamed _TIF_WORK_SYSCALL to _TIF_SYSCALL_WORK

AKASHI Takahiro (4):
  arm64: make a single hook to syscall_trace() for all syscall features
  arm64: split syscall_trace() into separate functions for enter/exit
  arm64: Add regs_return_value() in syscall.h
  arm64: is_compat_task is defined both in asm/compat.h and
    linux/compat.h
