Hello,

Excuse my very naive questions!

What "PDX" stands for in xen source code ? ( as in "PDX_GROUP_COUNT" )

and in this _expression_

"#define PDX_GROUP_COUNT ((1 << L2_PAGETABLE_SHIFT) / (sizeof(*frame_table) & -sizeof(*frame_table)))" , what is the meaning of "(sizeof(*frame_table) & -sizeof(*frame_table))" ?
