Linux Kernel Configuration
└─>Processor type and features
└─>Linear Address Masking support
In linux kernel since version 6.4 (release Date: 2023-06-25)  
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.
