The intent of this file is to give a brief summary of hugetlbpage support in
the Linux kernel. This support is built on top of multiple page size support
that is provided by most modern architectures. For example, i386
-architecture supports 4K and 4M (2M in PAE mode) page sizes, ia64
+architecture supports 4K and 4M (2M in PAE mode) page sizes, x86_64
+architecture supports 4K, 2M and 1G (SandyBridge or later) page sizes. ia64
architecture supports multiple page sizes 4K, 8K, 64K, 256K, 1M, 4M, 16M,
256M and ppc64 supports 4K and 16M. A TLB is a cache of virtual-to-physical
translations. Typically this is a very scarce resource on processor.
