Subject: [PATCH] arch-x86-pci-swiotlb-cleanup-patch
Date: Thu, 13 Aug 2009 17:18:04 +0300 [thread overview]
Message-ID: <200908131718.04623.mitov@issp.bas.bg> (raw)
Hi all,
This is a simple cleanup patch for arch/x86/kernel/pci-swiotlb.c file.
Deleted functions are already in lib/swiotlb.c, so no need to be duplicated.
The patch is against linux-2.6.31-rc5, compile/run tested on x86_64.
Best regards,
Marin Mitov
