Analyze and fix the following issue in the Linux kernel code: [PATCH] SCSI GFP fixes
Problem Details: Somebody forgot that | has higher priority than ?:. As the result, allocation is done with bogus flags - instead of GFP_ATOMIC + possibly GFP_DMA we always get GFP_DMA and no GFP_ATOMIC.

Problem Details: IXP2000 (ARM-based) platforms use a separate 'struct resource' for PCI MEM space. Resource allocation for PCI BARs always fails because the 'root' resource (the IXP2000 PCI MEM resource) always has the entire address space (00000000-ffffffff) free, and find_resource() calculates the size of that range...
