is there any problems making MAXPHYS smaller than MAXBSIZE ?
The Xen interface between dom0 and domU doesn't allow more than 11 pages
to be transfered at once, which is less than the default MAXPHYS on i386.
I'd like to limit it to 32k on Xen/domU as this would make things much
easier in the frontend driver, but if this means we can't mount filesystems
with 64k blocksize it's not an option.
