Subject: [PATCH 4/7] Introduce __pa_symbol()
Date: Thu, 19 Oct 2006 13:20:02 +0200 [thread overview]
Message-ID: <11612568062682-git-send-email-fbuihuu@gmail.com> (raw)
In-Reply-To: <11612568052624-git-send-email-fbuihuu@gmail.com>
This patch introduces __pa_symbol() macro which should be used to
calculate the physical address of kernel symbols. It also relies
on RELOC_HIDE() to avoid any compiler's oddities when doing
arithmetics on symbols.
