2021-10-04implement process_kill()dzwdz
2021-10-04remove support for processes returning strings on exitdzwdz

2021-10-02serial: implement a selftestdzwdz
2021-10-02rename kernel/arch/log.h to io.hdzwdz
it's not related to logging but to general io, the old name didn't make sense

2021-09-22remove some old leftover code in tar_driverdzwdz
2021-09-21start using sparse's `-Wnon-pointer-null`dzwdz
While I personally don't see a reason to use NULL instead of 0, I assume that whoever made that a sparse default knew what they were doing.

2021-09-21implement (safe) min/max macrosdzwdz
2021-09-21refactor `await_finish` into `process_try2collect`dzwdz

thanks to this i can tell which ones are placeholders, and which ones should stay

2021-09-19slightly tidy up some syscallsdzwdz
yay for pointless changes
2021-09-19show the malloc balance on halt; remove a bad kfree() calldzwdz

2021-09-19remove the unused static_strcmp macrodzwdz
2021-09-19call sysenter_setup before kmain_earlydzwdz
makes the code slightly simpler, imo
2021-09-19mark run_init as _Noreturndzwdz
2021-09-18_syscall_mount: actually use the just computed `backend` vardzwdz
whoops

2021-09-15fs_wait: pass the file ID toodzwdz
2021-09-14merge the `syscall_handler` and `_syscall` declarationsdzwdz
i think that making the call a bit more "transparent" makes the code nicer
