+[PATCH] kexec/uefi: copy secure_boot flag in boot params across kexec reboot
+
+Kexec reboot in case secure boot being enabled does not keep the secure boot
+mode in new kernel, so later one can load unsigned kernel via legacy kexec_load.
+In this state, the system is missing the protections provided by secure boot.
+
+Adding a patch to fix this by retain the secure_boot flag in original kernel.
+
+secure_boot flag in boot_params is set in EFI stub, but kexec bypasses the stub.
+Fixing this issue by copying secure_boot flag across kexec reboot.
