RISC-V: Change local interrupts from edge to level 
This effectively changes riscv_cpu_update_mip
from edge to level. i.e. cpu_interrupt or
cpu_reset_interrupt are called regardless of
the current interrupt level.

Fixes WFI doesn't return when a IPI is issued:

- https://github.com/riscv/riscv-qemu/issues/132

To test:

1) Apply RISC-V Linux CPU hotplug patch:

- http://lists.infradead.org/pipermail/linux-riscv/2018-May/000603.html

2) Enable CONFIG_CPU_HOTPLUG in linux .config

3) Try to offline and online cpus:

echo 1 > /sys/devices/system/cpu/cpu2/online
echo 0 > /sys/devices/system/cpu/cpu2/online
echo 1 > /sys/devices/system/cpu/cpu2/online

  • Clean/simple/lightweight/intuitive architecture-neutral API
  • Implemented in pure C language, with bindings for Crystal, Clojure, Visual Basic, Perl, Rust, Ruby, Python, Java, .NET, Go, Delphi/Free Pascal and Haskell.
  • Native support for Windows & *nix (with Mac OSX, Linux, *BSD & Solaris confirmed)
  • High performance via Just-In-Time compilation
  • Support for fine-grained instrumentation at various levels
  • Thread-safety by design
  • Distributed under free software license GPLv2
