From f6b83f070e9b7ad9075f7cc5646260e56c7d0219 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Mon, 20 Mar 2006 01:17:17 -0800 Subject: [SPARC64]: Fix 2 bugs in huge page support. 1) huge_pte_offset() did not check the page table hierarchy elements as being empty correctly, resulting in an OOPS 2) Need platform specific hugetlb_get_unmapped_area() to handle the top-down vs. bottom-up address space allocation strategies.
