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)

[-- 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
