In linux kernel since version 4.14.326 (release Date: 2023-09-23)
Linear Address Masking (LAM) modifies the checking that is applied
to 64-bit linear addresses, allowing software to use of the
untranslated address bits for metadata.
The capability can be used for efficient address sanitizers (ASAN)
implementation and for optimizations in JITs.
