From e5371ac566b6794f2125393b6850909de9e16f58 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Sun, 21 Oct 2007 16:41:33 -0700 Subject: update boot spec to 2.07 Updates for version 2.07 of the boot protocol. This includes: load_flags.KEEP_SEGMENTS- flag to request/inhibit segment reloads hardware_subarch - what subarchitecture we're booting under hardware_subarch_data - per-architecture data The intention of these changes is to make booting a paravirtualized kernel work via the normal Linux boot protocol.
