This pull request contains a handful of patches that have been floating
around various trees for a while but haven't made it upstream. These
patches all appear quite safe. They're all somewhat independent from
each other:
* One refactors our IRQ management function to allow multiple interrupts
to be raised an once. This patch has no functional difference.
* Cleaning up the op_helper/cpu_helper split. This patch has no
functional difference.
* Updates to various constants to keep them in sync with the latest ISA
specification and to remove some non-standard bits that snuck in.
* A fix for a memory leak in the PLIC driver.
* A fix to our device tree handling to avoid provinging a NULL string.
I've given this my standard test: building the port, booting a Fedora
root filesytem on the latest Linux tag, and then shutting down that
image. Essentially I'm just following the QEMU RISC-V wiki page's
instructions. Everything looks fine here.
We have a lot more outstanding patches so I'll definately be submitting
another PR for the soft freeze.
