Where can I find Linux kernel system call numbers?

Question

linux

Of course I googled. Everywhere it is recommended to look at the source codes of the kernel. But I need it for asm. That is, as I understand it, the number of the system call is transferred to the eax register. How to find out which parameters and which registers to transfer. Also, how to find out what the system call returns as a result of its execution? (That is, what returns to find out is just not a problem, the problem is how to find out, for example, the error number?)
