--------------> commit 181b3601a1a7d2ac3ace6b23cb3204450a4f9a27 Author: Jeremy Fitzhardinge <jeremy@goop.org> Date: Sun Jun 29 20:02:44 2008 -0700
x86: setup_arch() && early_ioremap_init() Looks like the setup.c unification missed the early_ioremap init from the early_ioremap unification. Unconditionally call early_ioremap_init(). needed for "x86/paravirt: groundwork for 64-bit Xen support".
