Allow building with clang
+ Release mode is sort of broken, as lto doesn't work with linker
relaxation and turning the relaxation off causes issues with the jump
from init to kernel (as I've currently implemented it, could probably
be fixed with a manual jump from assembly, I'll add it to my TODO
list)

Each IPC request +to a server temporarily maps the server's address space etc. into the calling +functions address space, except for the callstack. Callstack should be a bunch +of 4K pages, so they can easily be mapped to be unreachable by deeper nested +server calls, whereas the normal stack can be mapped to higher order pages to +save a little bit of memory access latency when the client is operating +normally. |
