- update dynamic printk format
- update addr2line for kernels by using script
- update qemu lines for vexpress
- add note about kaslr with qemu gdbserver
- use uart0 for console and uart1 for kgdb
- use 127.0.0.1 instead of localhost
(otherwise qemu and gdb get confused about IPv4 or IPv6)

fix various typos and wrong commands in slides2019-02-07T16:03:50ZHolger Denglerdengler@linutronix.de2019-02-05T11:10:44Zurn:sha1:1df58f151a324dbe97f1958fafc1471ec911c629
Fixes for:
- missing variable definition in Makefile

- missing trace-cmd subcmd and wrong parameter (sched_switch is an
event, not a plugin)
- missing #include in example code

replace *all* tabs with spaces2018-04-19T09:03:45ZJohn Ognessjohn.ogness@linutronix.de2018-04-19T09:03:45Zurn:sha1:ea793b23c98403cefb38670d02a778b843bdf997
There are times when tabs are allowed and times when they are not.
Let's just simply never use tabs for anything. This makes it easy
to find presentations where tabs were accidentally inserted.

module-basics: add device tree to vain2018-02-20T13:58:35ZJohn Ognessjohn.ogness@linutronix.de2018-01-31T04:46:56Zurn:sha1:0e7cb133ccdd77a66de18e095815737f5c4e3481
Modern kernels will use device trees for platform devices, so
make vain do the same.
(Also fixup an unnecessary line break.)
