Subject: [PATCH 13/13] memblock, x86: Replace memblock_x86_reserve/free_range() with generic ones
Date: Tue, 12 Jul 2011 11:16:06 +0200
Message-ID: <1310462166-31469-14-git-send-email-tj@kernel.org> (raw)
In-Reply-To: <1310462166-31469-1-git-send-email-tj@kernel.org>

Other than sanity check and debug message, the x86 specific version of
memblock reserve/free functions are simple wrappers around the generic
versions - memblock_reserve/free().

This patch adds debug messages with caller identification to the
generic versions and replaces x86 specific ones and kills them.
arch/x86/include/asm/memblock.h and arch/x86/mm/memblock.c are empty
after this change and removed.
