Subject: Use unchecked_isa_dma in sd_revalidate_disk()
From: Bernhard Walle <bwalle@xxxxxxx>
In sd_revalidate_disk(), the SCSI Disk driver needs a few bytes DMA memory,
allocated by kmalloc() and __GFP_DMA. This patch uses __GFP_DMA only if
the corresponding host structure has unchecked_isa_dma set.
