libc: Do not use the heavy variadic syscall() function for wrappers That function is meant more for user programs, and should still be rarely used, since it's not portable. Instead, we already know the number of arguments. We just call __lc_fast_syscallN, which also sets errno. 2022-10-27 15:42:00 +00:00			`#include <luna/syscall.h>`
Kernel, libc: Implement waitpid() FIXME: exec() is now doing weird page table stuff. But at least it works, no panics :) 2022-10-18 19:30:52 +00:00			`#include <sys/syscall.h>`
