Various updates. * Removed some variants of the SYS_GETINFO calls from the kernel; replaced them with new PM and utils libary functionality. Fixed bugs in utils library that used old get_kenv() variant. * Implemented a buffer in the kernel to gather random data. Memory driver periodically checks this for /dev/random. A better random algorithm can now be implemented in the driver. Removed SYS_RANDOM; the SYS_GETINFO call is used instead. * Remove SYS_KMALLOC from the kernel. Memory allocation can now be done at the process manager with new 'other' library functions. 2005-06-03 15:55:06 +02:00			`/* printf() - system services printf() Author: Kees J. Bot`

panic() cleanup. this change - makes panic() variadic, doing full printf() formatting - no more NO_NUM, and no more separate printf() statements needed to print extra info (or something in hex) before panicing - unifies panic() - same panic() name and usage for everyone - vm, kernel and rest have different names/syntax currently in order to implement their own luxuries, but no longer - throws out the 1st argument, to make source less noisy. the panic() in syslib retrieves the server name from the kernel so it should be clear enough who is panicing; e.g. panic("sigaction failed: %d", errno); looks like: at_wini(73130): panic: sigaction failed: 0 syslib:panic.c: stacktrace: 0x74dc 0x2025 0x100a - throws out report() - printf() is more convenient and powerful - harmonizes/fixes the use of panic() - there were a few places that used printf-style formatting (didn't work) and newlines (messes up the formatting) in panic() - throws out a few per-server panic() functions - cleans up a tie-in of tty with panic() merging printf() and panic() statements to be done incrementally. 2010-03-05 16:05:11 +01:00			`#include <stdio.h>`
