| Thread-topic: | [PATCH][HAP] P2M page table cleanup and bug fix |
|
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.
