Thread-topic:	[Xen-devel] [PATCH] Fix the boot of Linux guest while allocated more than 4G memory

Fix the boot of Linux guest if allocated more than 4G memory.
  - The p2m table will track the max_mapped_pfn, and while doing
p2m_gfn_to_mfn(), if the gfn is higher than max_mapped_pfn, the function
will return _mfn(INVALID_MFN). This makes the Linux guest kernel panic
with more than 4G memory. However when the gfn is a super page, the
max_mapped_page should be (gfn + (1UL << page_order) - 1) but not gfn.

Best Regards,
