Fix a problem in which a fault occured in an interrupt handler during copyin/copyout was erroneously detected as being occured by copyin.

- keep idepth in faultbuf and compare it to avoid unnecessary fault recovery
- make cpu_set_onfault() nestable to use bus_space_{peek,poke}()
  in hardware interrupt handlers during copyin & copyout.

- On some systems with a different cache line size (and DIC,IDC) per CPU, trap "mrs Xt,ctr_el0" instruction
  to return the minimum cache line size of the system to userland.
- add CLIDR_EL1 and CTR_EL0 to struct aarch64_sysctl_cpu_id.

On most systems, cache line size is the same for all CPUs, so this mechanism won't be required.
Rather, this is primarily for errata support, which will be committed later.

Various updates and improvements to cpu start up on arm/aarch64

- start sharing more code around the AP startup messaging.
- call arm_cpu_topology_set early so that ci_core_id is available for
  drivers, e.g. bcm2835_intr.c
- both arm and aarch64 now have
  - a static cpu_info_store array
  - the same arm_cpu_{hatched,mbox}

New function cpu_startup_hook on arm.

Called at end of cpu_startup.  Can be defined in, e.g., evbarm to do
additional stuff after cpu_startup.  Defined as a weak alias to a
function that does nothing, so optional.

Implement rndseed support in efiboot and fdt arm.

The EFI environment variable `rndseed' specifies the path to the
random seed.  It is loaded only for fdt platforms at the moment.
Since the rndseed (an rndsave_t object as defined in <sys/rndio.h>)
is 536 bytes long (for hysterical raisins), and to avoid having to
erase parts of the fdt tree, we load it into a physical page whose
address is passed in the fdt tree, rather than passing the content of
the file as an fdt node directly; the kernel then reserves the page
from uvm, and maps it into kva to call rnd_seed.

For now, the only kernel that does use efiboot with fdt is evbarm,
which knows to handle the rndseed.  Any new kernels that use efiboot
with fdt must do the same; otherwise uvm may hand out the page with
the secret key on it for a normal page allocation in the kernel --
which should be OK if there are no kernel memory disclosure bugs, but
would lead to worse consequences than simply loading the seed late in
userland with /etc/rc.d/random_seed otherwise.

Overhaul the API used to fetch and store individual memory cells in
userspace.  The old fetch(9) and store(9) APIs (fubyte(), fuword(),
subyte(), suword(), etc.) are retired and replaced with new ufetch(9)
and ustore(9) APIs that can return proper error codes, etc. and are
implemented consistently across all platforms.  The interrupt-safe
variants are no longer supported (and several of the existing attempts
at fuswintr(), etc. were buggy and not actually interrupt-safe).

Also augmement the ucas(9) API, making it consistently available on
all plaforms, supporting uniprocessor and multiprocessor systems, even
those that do not have CAS or LL/SC primitives.

Welcome to NetBSD 8.99.37.

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
