This adds map/unmap_single_attr and map/unmap_sg_attr to struct
dma_mapping_ops. This enables us to move the dma operations in struct
ia64_machine_vector to struct dma_mapping_ops.
Note that we will remove map/unmap_sg and map/umap_single.
This is a preparation of struct dma_mapping_ops unification.

As noted by Akinobu Mita in patch b1fceac2b9,
alloc_bootmem and related functions never return NULL and always return a
zeroed region of memory. Thus a NULL test or memset after calls to these
functions is unnecessary.
This was fixed using the following semantic patch.

Impact: use new cpumask API to reduce stack usage
Replace the saving of current->cpus_allowed and set_cpus_allowed_ptr() with
a work_on_cpu function for read_measured_perf_ctrs().
Basically splits off the work function from get_measured_perf which is
run on the designated cpu. Moves definition of struct perf_cur out of
function local namespace, and is used as the work function argument.
References in get_measured_perf use values in the perf_cur struct.

This is part of an effort to reduce structure sizes for machines
