The accept_memory kernel parameter was added in commit dcdfdd40fa82
("mm: Add support for unaccepted memory") but not listed in the

+ accept_memory= [MM]
+ Format: { eager | lazy }
+ default: lazy
+ By default, unaccepted memory is accepted lazily to
+ avoid prolonged boot times. The lazy option will add
+ some runtime overhead until all memory is eventually
+ accepted. In most cases the overhead is negligible.
+ For some workloads or for debugging purposes
+ accept_memory=eager can be used to accept all memory
+ at once during boot.
