Subject: [PATCH 191/237] efi: really mark memory of unknown type as reserved |
|
|
|
9be4c45dbe3c877d1f4856e99ee15133c6cd2261 added switch case between |
|
fall through cases, causing all memory regions of unknown type to be |
|
marked as available. |
|
|
|
Move default case into its own block and add explicit FALLTHROUGH |
|
annotation. |
|
