From 913437e8a268130b7fbfb9d6d366c42de4f681be Mon Sep 17 00:00:00 2001 From: Jacob Garber Date: Fri, 31 May 2019 12:53:54 -0600 Subject: console: Make die() and friends variadic die() currently only accepts a fixed message string, which is rather inconvenient when there is extra information that would be helpful to print in the error message. This currently requires an extra call to printk(), which is somewhat awkward: printk(BIOS_EMERG, "Bad table, opcode %d at %d", id, i); die(""); // what do I say here? die() already has a printk() inside it to print the error message, so let's just make it variadic to combine the two. die("Bad table, opcode %d at %d", id, i); // much better Forwarding variadic arguments from one function to another is rather tricky, so die_with_post_code() is redefined as a variadic macro instead.
