Subject: [PATCH v3 0/3] make kexec work with efi=noruntime or efi=old_map

This patch series fix the kexec panic on efi=noruntime or efi=old_map
pass acpi_rsdp_addr to the second kernel and make it boot up properly.

Update from V2:
 - Store acpi rsdp value, and add an acpi_os_get_root_pointer_late as
   a helper, leveraging existing codes so we don't need to reparse RSDP.

Update from V1:
 - Add a cover letter and fix some type in commit message
 - Previous patches are not sent in a single thread

Kairui Song (3):
  x86, kexec_file_load: Don't setup EFI info if EFI runtime is not
    enabled
  acpi: store acpi_rsdp address for later kexec usage
  x86, kexec_file_load: make it work with efi=noruntime or efi=old_map
