linux-toradex.git/arch/x86/kernel/reboot_32.S, branch v3.2.55 Linux kernel for Apalis and Colibri modules x86, reboot: Fix relocations in reboot_32.S 2011-05-02T21:44:46+00:00 H. Peter Anvin hpa@zytor.com 2011-05-02T21:33:24+00:00 7806a49ab625ebeb1709e5e87299b64932b807a7 The use of base for %ebx in this file is arbitrary, *except* that we also use it to compute the real-mode segment. Therefore, make it so that r_base really is the true address to which %ebx points. This resolves kernel bugzilla 33302.

The use of base for %ebx in this file is arbitrary, *except* that we
also use it to compute the real-mode segment.  Therefore, make it so
that r_base really is the true address to which %ebx points.

This resolves kernel bugzilla 33302.

I had changed the interfaces, but not the actual implementation!
