-DKERNEL_BASE_VOFFSET= has annoyed me for the last time...

Introduce KERNEL_VOFFSET_RUNTIME which prevents the addition of
-DKERNEL_BASE_VOFFSET= to the command line and use it on the
__HAVE_GENERIC_START kernels which do runtime calculation of the
offset.

Mirror the changes to aarch64 and

- Switch to TPIDRPRW_IS_CURLWP, because curlwp is accessed much more often
  by MI code.  It also makes curlwp preemption safe,

- Make ASTs operate per-LWP rather than per-CPU, otherwise sometimes LWPs
  can see spurious ASTs (which doesn't cause a problem, it just means some
  time may be wasted).

- Make sure ASTs are always set on the same CPU as the target LWP, and
  delivered via IPI if posted from a remote CPU so that they are resolved
  quickly.

- Add some cache line padding to struct cpu_info.

- Add a memory barrier in a couple of places where ci_curlwp is set.  This
  is needed whenever an LWP that is resuming on the CPU could hold an
  adaptive mutex.  The barrier needs to drain the CPU's store buffer, so
  that the update to ci_curlwp becomes globally visible before the LWP can
  resume and call mutex_exit().

Provide generic start code that assumes the MMU is off and caches are
disabled as per the linux booting protocol for ARMv6 and ARMv7 boards.
u-boot image type should be changed to 'linux' for correct behaviour.

The new start code builds a minimal "bootstrap" L1PT with cached access
disabled and uses the same table for all processors.  AP startup is
performed in less steps and more code is written in C.

The bootstrap tables and stack are placed into an (orphaned) section
"_init_memory" which is given to uvm when it is no longer used.

Various kernels have been converted to use this code and tested.  Some
boards were provided by TNF. Thanks!

The GENERIC kernel now boots on boards using the TEGRA, SUNXI and EXYNOS
kernels. The GENERIC kernel will also work on RPI2 using u-boot.

Thanks to martin@ and aymeric@ for testing on parallella and nanosoc
respectively
