Subject: [RFC 06/10] powerpc: vmlinux.lds.S cleanup - use PERCPU, THREAD_SIZE macroses
Date: Wed, 27 Feb 2008 23:58:37 +0300	[thread overview]
Message-ID: <20080227210003.720942920@gmail.com> (raw)
In-Reply-To: <20080227205831.150784453@gmail.com>

[-- Attachment #1: powerpc-vmlinux --]
[-- Type: text/plain, Size: 1339 bytes --]

This patch includes  thread_info.h header into liker script that
allow us to use THREAD_SIZE macro instead of numeric constant

Also PERCPU macro is used instead of explicit section definition
