Subject: [077/116] iwlwifi: use dma_alloc_coherent
2.6.32-stable review patch. If anyone has any objections, please let us know.
------------------
From: Stanislaw Gruszka <sgruszka@...hat.com>
commit f36d04abe684f9e2b07c6ebe9f77ae20eb5c1e84 upstream.
Change pci_alloc_consistent() to dma_alloc_coherent() so we can use
GFP_KERNEL flag.
