Subject[PATCH 0/2] x86: Fix issues when eXecute Disable (XD) bit is disabled in uEFI firmware
Message-ID<qBMgp-3Ms-5@gated-at.bofh.it>
The kernel panics early in boot on a x86_64 server if the eXecute
Disable (XD) bit is set to disabled in the uEFI firmware.

The following patches fix the panic and also fix an error in
kernel_map_pages_in_pgd() which would make the EFI runtime service
unavailable when the XD bit is set to disabled.

  x86: Fix error in kernel_map_pages_in_pgd() when booting with XD disabled
