From eb8307595baa729a12db0fec9a80910b13bd6fc8 Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Sun, 6 May 2007 14:51:07 -0700 Subject: uml: create arch.h This patch moves the declarations of the architecture hooks from user_util.h to a new header, arch.c, and adds the necessary includes to files which need those declarations.

This makes the types match reality, except in arch_fixup, which is changed to operate on a union uml_pt_regs. This fixes a bug in the call from segv_handler, which passes a union uml_pt_regs, to segv, which expects to pass a struct sigcontext to arch_fixup. Whitespace and other style fixes. There's also a errno printk fix.
