Hi,

I'm trying to get a shared memory segment of just under 2 gb.  So
far, I've been able to get a 893mb shared segment by altering the
_SHM_IDX_BITS to 18 in include/asm/shmparam.h using the 2.2.0
kernel.  I'm assuming I can set the _SHM_IDX_BITS to 19 without a
problem (more overhead though), but since this is my "working"
computer, I don't want any surprises.  is this possible without
breaking something?  I glanced at the code but didn't see any
obvious "gotchas".

Don't ask why I don't use multiple segments.  It's not my
decision.
