Subject: [RFC 09/10] alpha: vmlinux.lds cleanup - use THREAD_SIZE macro
Date: Wed, 27 Feb 2008 23:58:40 +0300	[thread overview]
Message-ID: <20080227210004.407632127@gmail.com> (raw)

[-- Attachment #1: alpha-vmlinux --]
[-- Type: text/plain, Size: 2491 bytes --]

This patch modifies thread_info.h header to be able to include it
into linker script and then we're able to use THREAD_SIZE in
vmlinux.lds
