Increasing shared memory segments on 2.2

[Dan Mueth]

Could somebody help me increase the number of shared memory segments
above 128?

It looks like I just need to up _SHM_ID_BITS from 7 to 8 in
include/asm/shmparam.h.  Will this do it?  Do I need to do anything else?

Can I up it to 9 without any problems?

Thanks,

Dan
