Huge Pages for Virtual-Memory Objects

Currently, Morsels only support 4-KiB pages, but with larger page sizes the management overhead could be further reduced and the average memory access could be sped up, due to faster page-table walks and an increased TLB coverage.

Pruning of Soft-Error Fault Spaces by Dynamic Register-Usage Tracing in a Formal Instruction-Set Model
