I've been working on the same issue so that I have some patches.
I attached a part of them. Although they should be adjusted to 
your patch which is to be commited, I wanted to send these out before 
checking in.
If necessary, I'm willing to update them.

- acm code uses NR_GRANT_ENTRIES.
  The attached patch is only compile-tested.

- IA64 code needs a slight domain initialization adjustment.

- PPC code depends on the fact that shared grant table is machine continguous.
  I'm not familiar with PPC code so that I'm not sure how to solve it.
  If arch specific code can override maximal grant table size,
  Xen/PPC can prohibit growing grant table.
  After solving the issue, they can allow to grow grant table.
