[PATCH] x86_64: no TIOCSBRK/TIOCCBRK in ia32 emulation
In ia32 emulation, the amd64 kernel refuses the ioctls TIOCSBRK and
TIOCCBRK with EINVAL. I've attached a patch that adds them to the
compatibility list.
Since all architectures have these ioctls ("m68knommu" inherits them from
"m68k", "um" from its host) and use the same code, I think adding them to
compat_ioctl.h is the correct choice (as opposed to adding them to
arch/x86_64/ia32/ia32_ioctl.c).
