Right, so where is virtual mapping of control page established?
I could not find relevant code in SLES kernel which does that.
In the hypervisor (xen/arch/x86/machine_kexec.c:machine_kexec_load()).

At worst case I will send reply when I will be

Some implementations (e.g. Xen PVOPS) could not use part of identity page table
to construct transition page table. It means that they require separate PUDs,
PMDs and PTEs for virtual and physical (identity) mapping. To satisfy that
requirement add extra pointer to PGD, PUD, PMD and PTE and align
