inclusion in the kernel.
Patchwork
---------
RISC-V has a patchwork instance, where the status of patches can be checked:
https://patchwork.kernel.org/project/linux-riscv/list/
If your patch does not appear in the default view, the RISC-V maintainers have
likely either requested changes, or expect it to be applied to another tree.
Automation runs against this patchwork instance, building/testing patches as
they arrive. The automation applies patches against the current HEAD of the
RISC-V `for-next` and `fixes` branches, depending on whether the patch has been
detected as a fix. Failing those, it will use the RISC-V `master` branch.
The exact commit to which a series has been applied will be noted on patchwork.
Patches for which any of the checks fail are unlikely to be applied and in most
cases will need to be resubmitted.
Submit Checklist Addendum
-------------------------
We'll only accept patches for new modules or extensions if the

Typically programs will register a set of events that they wish to expose to
