Thanks Gavin.  I had tried that.  The problem is, this particular flag is
not a user-selectable one, and even if I enable it by directly editing the
vendors/.../config.linux, it always gets undone when I actually go and
configure my kernel.  This option seems to be forcibly enforced by the
Kconfig.  There's got to be some way to keep it without hacking the Kconfig.

Thanks,
