From 9735e91e9c29c0d8fe432aef1152e43e50bdb316 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Thu, 24 Jan 2013 12:19:50 -0800 Subject: x86, 64bit, realmode: Use init_level4_pgt to set trampoline_pgd directly with #PF handler way to set early page table, level3_ident will go away with 64bit native path. So just use entries in init_level4_pgt to set them in trampoline_pgd.
