The "KernelPageSize" entry is the pagesize used by the kernel to
back a VMA. This matches the size used by the MMU in the majority
of cases. However, one counter-example occurs on PPC64 kernels
whereby a kernel using 64K as a base pagesize may still use 4K
pages for the MMU on older processor. To distinguish, this
patch reports "MMUPageSize" as the pagesize used by the MMU.

The "Locked" indicates whether the mapping is locked in memory

"VmFlags" field represents the kernel flags associated with
