From 4614a3a3b638dfd7a67d0237944f6a76331af61d Mon Sep 17 00:00:00 2001 From: Jes Sorensen Date: Mon, 22 Oct 2007 11:03:29 +1000 Subject: Reorder guest saved regs to match hyperall order Move eax next to ebx/ecx/edx in struct lguest_regs on i386, so they will be located together and allow it to map directly to a struct hcall_ring entry (which will be renamed struct hcall_args as in a subsequent patch). This is in preparation for making the code hcall code architecture independent.
