Subject: [PATCH] pci/dmar: fix section mismatch in dmar_ir_support()
Date: Sun, 11 Oct 2009 21:20:49 -0700	[thread overview]
Message-ID: <1255321249-25546-1-git-send-email-bebarino@gmail.com> (raw)
In-Reply-To: <1254543340-4473-1-git-send-email-bebarino@gmail.com>

dmar_ir_support() references dmar_tbl which is annotated with
__initdata. The only caller of dmar_ir_support() is
intr_remapping_supported() also annotated with __init. Therefore add the
__init annotation to dmar_ir_support().

WARNING: drivers/pci/built-in.o(.text+0xa110): Section mismatch in
reference from the function dmar_ir_support() to the variable
.init.data:dmar_tbl
The function dmar_ir_support() references
the variable __initdata dmar_tbl.
This is often because dmar_ir_support lacks a __initdata
annotation or the annotation of dmar_tbl is wrong.

I sent this a week back but it looks like it didn't stick. Hopefully it
does this time.
