Subject: [PATCH 15/23] x86, realmode: Move trampoline_*.S early in the link order
Date: Tue, 8 May 2012 21:22:38 +0300 [thread overview]
Message-ID: <1336501366-28617-16-git-send-email-jarkko.sakkinen@intel.com> (raw)
In-Reply-To: <1336501366-28617-1-git-send-email-jarkko.sakkinen@intel.com>
From: "H. Peter Anvin" <hpa@linux.intel.com>
Move trampoline_*.S earlier in the link order so it ends up being
first in the text segment; since the SIPI vector requires 4K alignment
it otherwise ends up padding the .text segment with that much
completely unnecessarily.
