b602d64b59 dashboard/config: disable /dev/{mem,kmem,ioport} in syzbot bits 
If syzkaller gets to /dev/{mem,kmem,ioport}, it will destroy the machine.
It managed to do so with some mount's, chdir's and bogus file names.
These are not needed for fuzzing, so completely disabling them is
the simplest and the most reliable option.

a970258ea5 dashboard/config: better extract usb configs 
When generating a USB config, disable USB symbols that are disabled in the
base config, as they might have been enabled when some of the dependecies
got enabled.

6c19c36919 dashboard/config: improve config generation scripts 
1. Use MAKE_ARGS var to pass arguments to make.
2. Pass -m to merge_config.sh to avoid calling make without CC.
3. Make util_add_syzbot_extra_bits() operate on .config.

dashboard, sys/linux: extract more HID USB configs (#1310) 
Some USB drivers don't depend on core USB symbols, but rather depend on a
generic symbol for some input subsystem (e.g. HID). Account for that when
extracting USB configs.

It also updates upstream-kmsan.config

ffec3d1894 dashboard/config: add lsm= cmdline arg for stacked modules 
It won't take effect right now as security= has precedence over lsm=.
But it won't harm too and later we will only need to remove security=.
Also it will work with this custom patch for syzbot:
https://groups.google.com/d/msg/syzkaller/BSgVCTSShRQ/E6lFuiDpFwAJ

aa53be276d dashboard/config: prepare for stacked security modules 
In linux-next security modules can be stacked.
TOMOYO is compatible with other modules and SAFESETID
module is added. But this is not yet in mainline.

Enable TOMOYO and SAFESETID.
There is no way to enable stacked modules in linux-next
while preserving the current behavior in mainline.
Once these changes reach mainline, we will need to replace
security cmdline arguments with lsm as follows:

lsm=yama,safesetid,integrity,selinux,tomoyo
lsm=yama,safesetid,integrity,smack,tomoyo
lsm=yama,safesetid,integrity,tomoyo,apparmor

7da2392541 pkg/report: support CONFIG_PRINTK_CALLER 
CONFIG_PRINTK_CALLER has reached linux-next:
https://groups.google.com/d/msg/syzkaller/xEDUgkgFvL8/d5bBS3BJBwAJ

Enable CONFIG_PRINTK_CALLER and support parsing of its output format.

This gives us several advantages:
 - output from different contexts don't intermix
 - intermixed output doesn't cause corrupted reports
 - we can keep larger prefix since we know it comes from the same task

Credit for the kernel part goes to Tetsuo Handa.
Also Sergey Senozhatsky and Petr Mladek for reviews of the kernel part.
