Subject: [PATCH x86_64]: Add TCSBRKP ioctl translation for arch/x86_64/ia32

Hi,

The following patch adds TCSBRKP ioctl translation for arch/x86_64/ia32.
TCSBRKP is needed for POSIX tcsendbreak().
Some archs (such as sparc64) have added TCSBRKP in their compat codes,
Here is for x86_64.

This is not the optimal solution, for two reasons:

- If it is needed on all architectures, you should instead remove it
from the ones that currently define it and put it in
include/linux/compat_ioctl.h.

- It is not actually COMPATIBLE_IOCTL, but rather ULONG_IOCTL,
as far as I can tell. Yes, I made the same mistake in
arch/s390/kernel/compat_ioctl.c, but you can fix it now
that you are touching it anyway.
