The idea behind this is: we don't want to keep tracking of huge pages when
logging_active is true, which will result in performance degradation. We
still need to set vma_pagesize to PAGE_SIZE, so that we can make use of it

Remove mixed indentation in Python scripts. Revert to either all
tabs (most common form) or all spaces (4 or 8) depending on what
was the intent of the original commit. This is necessary to
complete Python3 support as it will flag an error if it encounters
mixed indentation.

I think it's better not to change this unless
the compilation unit already uses a mix of styles.
Overall, the kernel uses "0x%" over "%#"

You might want to use %px here if you _really_
want the actual address and not the hashed output
%p normally produces.

There less than 100 uses of KERN_DEFAULT.
Relatively speaking, KERN_DEFAULT hasn't existed all
that long actually.

This extends the "console=" interface to allow setting the per-console
loglevel by adding "/N" to the string, where N is the desired loglevel
expressed as a base 10 integer. Invalid values are silently ignored.

Not all consoles are created equal: depending on the actual hardware,
the latency of a printk() call can vary dramatically. The worst examples
are serial consoles, where it can spin for tens of milliseconds banging
the UART to emit a message, which can cause application-level problems
when the kern

The big change here is the 3rd patch, which actually wires up the console
drivers to support embedding a device structure, so we can place them on
a "console" bus and expose attributes in
