Date: Thu, 30 Apr 2009 19:56:14 -0400 From: Tim Abbott <tabbott@....EDU> To: Sam Ravnborg <sam@...nborg.org> Cc: Linux kernel mailing list <linux-kernel@...r.kernel.org>, Anders Kaseorg <andersk@....edu>, Waseem Daher <wdaher@....edu>, Denys Vlasenko <vda.linux@...glemail.com>, Jeff Arnold <jbarnold@....edu>, Benjamin Herrenschmidt <benh@...nel.crashing.org>, Paul Mackerras <paulus@...ba.org>, linuxppc-dev@...abs.org, Tim Abbott <tabbott@....edu> Subject: [PATCH 5/8] powerpc: use new macro for .data.cacheline_aligned section. .data.cacheline_aligned should not need a separate output section; this change moves it into the .data section. Since there isn't an ALIGN() directive before the .data.cacheline_aligned scetion in the current linker script, I'd like an ack from one of the powerpc maintainers that L1_CACHE_BYTES is the correct alignment here.
