[PATCH v2 0/3] ARM support for syscall tracing

[Wade Farnsworth]

This is a rework of Steven Walter's syscall tracing patches first
posted here:

http://lists.infradead.org/pipermail/linux-arm-kernel/2011-November/074454.html

I've rebased the patches against the current mainline master branch, as well
as implemented several changes based on feedback from Will Deacon and
Russel King.

v2: - Tested on EABI and OABI.
    - Removed an instance of the ?: operator in syscall_set_return_value()
    - Moved #define of NR_syscalls to syscall.h
    - Changed the test of NR_syscalls vs __NR_syscalls in entry-common.S
      to .ifne

Wade Farnsworth (3):
  ARM: add support for the generic syscall.h interface
  ARM: add TRACEHOOK support
  ARM: support syscall tracing
