With this patch set I continue the effort of upstreaming the eznps platform for arch/arc.

It comprise of couple of patches from last set yet not accepted,
patches for HW erratas and some misc extensions such for HIGHMEM / NUMA.

This set got more generic ARC changes than previous set.
Additional ifdef seem like unavoidable, however it may seem Ugly.
Let's see if we need to do it more elegant.

Elad Kanfi (1):
ARC: [plat-eznps] avoid toggling of DPC register

Liav Rehana (2):
ARC: [plat-eznps] Update the init sequence of aux regs per cpu.
ARC: [plat-eznps] handle dedicated AUX registers

Noam Camus (8):
ARC: set level of log per CPU during boot to be debug level
ARC: send ipi to all cpus sharing task mm in case of page fault
ARC: Allow irq threading
ARC: Add CPU topology
ARC: Support more than one PGDIR for KVADDR
ARC: [NUMA] added CONFIG_NUMA for plat-eznps
ARC: [plat-eznps] new command line argument for HW scheduler at MTM
ARC: [plat-eznps] Save/Restore extra auxiliary registers
