Kexec bypasses EFI's switch to virtual mode. In exchange, it has its own routine, kexec_enter_virtual_mode(), which replays the mappings made by the original kernel. Unfortunately, that function fails to reinstate EFI's memory attributes, which would've otherwise been set after entering virtual mode. Remediate this by calling efi_runtime_update_mappings() within kexec's routine. Signed-off-by: Nicolas Saenz Julienne <nsaenz@amazon.com> Signed-off-by: Ard Biesheuvel <ardb@kernel.org> |
