Impact: cleanup, solve 80 columns wrap problems
mpc_config_bus should be renamed to mpc_bus.
The reason: the 'c' in MPC already means 'config' -
no need to repeat that in the type name.

Impact: fix debug/crash printout
Since errorcode is popped out, RIP is on the top of the stack.
Use real RIP value instead of wrong CS.

Impact: cleanup
__alloc_bootmem and __alloc_bootmem_node do panic
for us in case of fail so no need for additional
checks here.
Also lets use pr_*() macros for printing.

Impact: Reduce inter-node memory traffic.
Reduces inter-node memory traffic (offloading the global system bus)
by allocating referenced struct cpumasks on the same node as the
referring struct.

Impact: Reduce memory usage, use new API.
This is part of an effort to reduce structure sizes for machines
configured with large NR_CPUS. cpumask_t gets replaced by
cpumask_var_t, which is either struct cpumask[1] (small NR_CPUS) or
struct cpumask * (large NR_CPUS).

Impact: Reduce future system panics due to cpumask operations using NR_CPUS
Insure that code does not look at bits >= nr_cpu_ids as when cpumasks are
allocated based on nr_cpu_ids, these extra bits will not be defined.
Also some other minor updates:
* change in to use cpu accessor function set_cpu_present() instead of
directly accessing cpu_present_map w/cpu_clear() [arch/x86/kernel/reboot.c]
* use cpumask_of() instead of &cpumask_of_cpu() [arch/x86/kernel/reboot.c]
* optimize some cpu_mask_to_apicid_and functions.

Impact: enables /sys/devices/system/cpu/{kernel_max,offline} user interface
By setting total_cpus, the drivers/base/cpu.c will display the
values of kernel_max (NR_CPUS-1) and the offlined cpu map.

Imapct: add a new struct member to 'struct protection_domain'
When using protection domains for dma_ops and KVM its better to know for
which subsystem it was allocated. Add a flags member to struct
protection domain for that purpose.

Impact: save unneeded logic to add and remove domains to the list
The removal of a protection domain from the iommu_pd_list is not
necessary. Another benefit is that we save complexity because we don't
have to readd it later when the device no longer uses the domain.
