Pull x86 boot updates from Thomas Gleixner:
"Assorted updates to kexec/kdump:
- Proper kexec support for 4/5-level paging and jumping from a
5-level to a 4-level paging kernel.
- Make the EFI support for kexec/kdump more robust
- Enforce that the GDT is properly aligned instead of getting the
alignment by chance"
* 'x86-boot-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/kdump/64: Restrict kdump kernel reservation to <64TB
x86/kexec/64: Prevent kexec from 5-level paging to a 4-level only kernel
x86/boot: Add xloadflags bits to check for 5-level paging support
x86/boot: Make the GDT 8-byte aligned
x86/kexec: Add the ACPI NVS region to the ident map
x86/boot: Call get_rsdp_addr() after console_init()
Revert "x86/boot: Disable RSDP parsing temporarily"
x86/boot: Use efi_setup_data for searching RSDP on kexec-ed kernels
