[PATCH] arch-x86-pci-swiotlb-cleanup-patch

[Marin Mitov]

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
