From 53492b1de46a7576170e865062ffcfc93bb5650b Mon Sep 17 00:00:00 2001 From: Gerald Schaefer Date: Wed, 30 Apr 2008 13:38:46 +0200 Subject: [S390] System z large page support. This adds hugetlbfs support on System z, using both hardware large page support if available and software large page emulation on older hardware. Shared (large) page tables are implemented in software emulation mode, by using page->index of the first tail page from a compound large page to store page table information.
