From: Glauber de Oliveira Costa Date: Wed, 30 Jan 2008 12:31:41 +0000 (+0100) Subject: x86: move i387 definitions to processor.h X-Git-Tag: Ubuntu-5.0.0-8.9~36934^2~529 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=46265df040533f57c191bb2b019d6b25c3bf1f34;p=mirror_ubuntu-disco-kernel.git x86: move i387 definitions to processor.h This patch moves i387 definitions from processor_32.h and processor_64.h to processor.h. They are different. Very different. And there's appearently nothing we can do about it, so they're enclosed inside ifdefs.
