422	DMA allocator needs to support range and alignment specification	Martin Decky	Martin Decky	"The DMA allocator for anonymous memory needs to support proper specification of memory range (e.g. for ISA hardware which is limited to physical addresses below 16 MB on ia32 and PCI hardware below 4 GB on amd64) and alignment (ISA hardware limited to 128k-aligned blocks).

Both the range and alignment specification can be provided by a single bit mask (showing 1s in bits of the physical address that the DMA allocator is allowed to set)."	enhancement	closed	major	0.6.0	helenos/kernel/generic	mainline	fixed
