This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: dma_declare_coherent_memory wrong allocation
From: Guennadi Liakhovetski <[EMAIL PROTECTED]>
dma_declare_coherent_memory() allocates a bitmap 1 bit per page, it
calculates the bitmap size based on size of long, but allocates bytes...
Thanks to James Bottomley for clarifications and corrections.
