Use kernel_ident_mapping_init() to initialize kernel page tables where
possible, replacing manual initialization, reducing code duplication.

Kirill A. Shutemov (3):
  x86/mm/ident_map: Fix virtual address wrap to zero
  x86/acpi: Replace manual page table initialization with
    kernel_ident_mapping_init()
  x86/64/kexec: Rewrite init_transition_pgtable() with
    kernel_ident_mapping_init()
