| |
2.6.32-longterm review patch. If anyone has any objections, please let me know.
------------------
From: Anton Blanchard <anton@samba.org>
commit 5e95235ccd5442d4a4fe11ec4eb99ba1b7959368 upstream.
Recent toolchains force the TOC to be 256 byte aligned. We need to enforce this alignment in our linker script, otherwise pointers to our TOC variables (__toc_start, __prom_init_toc_start) could be incorrect.
If they are bad, we die a few hundred instructions into boot.
