Subject: ALSA: emu10k1 - Fix page allocation with GFP_DMA
X-Git-Tag: v2.6.27-rc1~1111^2~103
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=781711a93e8aae756e8ae07acef185a6dfe552b8;p=linux-2.6-omap-h63xx.git

ALSA: emu10k1 - Fix page allocation with GFP_DMA

Added the missing GFP_ATOMIC to page_alloc when called with GFP_DMA.
GFP_KERNEL often results in stalls for ZONE_DMA, so GFP_ATOMIC is more
prgmatic.
