Simplify TLS handling.
Since TLS pointer cannot be changed directly from userland is not necessary to save it on each task switch.
Cleanup exception.S. Prepare for later unification of data_abort_handler() and prefetch_abort_handler().
Add errata framework to cpuinfo.
Implement (partially) TLB IPI.
Add new ARMv6 specific trap-v6.c.
Add new pmap code.
Switch DMA coherent memory to normal uncacheable memory
As per Alan L. Cox recommendation, remove lazy switch.
Remove now useless .arch directive form assembler files.
Make ofwbus as a subclass of simplebus. Remove bogus checking for busy resource.
Remove now duplicated code from ofwbus.c. Move all useful methods into simplebus.c.
Move resource managers for IRQ and memory from ofwbus to nexus.
Other code uses 0 for invalid phandle, so use it in simplebus_get_devinfo() too.
Rename Exynos UART. No functional change.
Don't use C++ reserved word "class" in uart_cpu_fdt.c. No functional change.
Use linker set for UARTs definition
