14 hourskern/amd64: Implement syscall domains and windowsIan Moffett
A syscall domain in the L5 kernel is a fixed list of "syscall windows", each syscall window represents a specific platform and/or syscall model. A platform latch within each domain determines which window / platform should be visible. Since syscall domains are per-process, these changes are local to their respective processes.

This commit introduces load balancing of processes between cores by using a scalable "CPU arbiter" which decides how to fetch the next core descriptor. Signed-off-by: Ian Moffett <ian@osmora.org>
32 hourskernel/amd64: mp: Use NULL instead of wrappingIan Moffett
It is best to return NULL when there is no next CPU instead of wrapping so we have an indicator at where the list ends. Signed-off-by: Ian Moffett <ian@osmora.org>
