[PATCH 3/3] ARM: wire up new pkey syscalls

[Russell King]

Wire up the new pkey syscalls for ARM.  This illustrates the ease that
the generated/tabular approach gives us: adding new system calls
becomes much easier, and all the dependencies are automatically handled
for the update.

Of course, this is development, and there will be a patch for -rc2 to
wire these up in due course.  I'm using this as an illustration for
this approach - compared with f2335a2a0a59 ("ARM: wire up preadv2 and
pwritev2 syscalls") adding two syscalls, with a diffstat of:

 arch/arm/include/asm/unistd.h      | 2 +-
 arch/arm/include/uapi/asm/unistd.h | 2 ++
 arch/arm/kernel/calls.S            | 4 +++-
 3 files changed, 6 insertions(+), 2 deletions(-)

vs this patch adding three plus reserving two, giving:

 arch/arm/tools/syscall.tbl | 5 +++++
 1 file changed, 5 insertions(+)
