Actually the error is something else, I missed this in the debug output:

xc: error: Failed to get types for pfn batch (7 = Argument list too long): 
Internal error

write_batch() should probably split the requests when filling types[] because
Xen has "1024" hardcoded in XEN_DOMCTL_getpageframeinfo3...
