Hou Wenlong 63dc2c34a9 x86/xen: Build identity mapping page tables dynamically for XENPV
After commit 47ffe0578a ("x86/pvh: Add 64bit relocation page tables"),
the PVH entry uses a new set of page tables instead of the
preconstructed page tables in head64.S. Since those preconstructed page
tables are only used in XENPV now and XENPV does not actually need the
preconstructed identity page tables directly, they can be filled in
xen_setup_kernel_pagetable(). Therefore, build the identity mapping page
table dynamically to remove the preconstructed page tables and make the
code cleaner.
