19 details. On the x86-64 architecture, HugeTLB pages of size 2MB and 1GB are
20 currently supported. Since the base page size on x86 is 4KB, a 2MB HugeTLB page
34 architectures. Because arm64 supports 4k, 16k, and 64k base pages and

79 This optimization only supports 64-bit system, so the value of sizeof(pte_t)
81 is a power of two. In most cases, the size of ``struct page`` is 64 bytes (e.g.
