This patchset changes kernel decompression code to use trampoline to
switch between paging modes.

The patchset is replacement for previously reverted patch "Handle 5-level
paging boot if kernel is above 4G".

Please review and consider applying.

Kirill A. Shutemov (4):
  x86/boot/compressed/64: Make sure we have 32-bit code segment
  x86/boot/compressed/64: Use stack from trampoline memory
  x86/boot/compressed/64: Use page table in trampoline memory
  x86/boot/compressed/64: Handle 5-level paging boot if kernel is above 4G
