[Xen-devel] [PATCH][HAP] P2M page table cleanup and bug fix

["Huang2, Wei" <Wei.Huang2@xxxxxxx>]

This patch forces P2M top-level page table to be allocated below 4GB memory space when Xen is running under PAE mode. It also removes hap.p2m_freelists because hap mode does not have P2M batch allocation. The backpointer parameter of hap_alloc() function is removed since this parameter is useless.
