Subject: [PATCH v4 0/3] arm64: prerequisites for audit and ftrace

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

Patch [1/3] 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 [2/3] 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 [3/3] adds a commonly used function, which returns a return value of
system call.

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 (3):
  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
