When tuning the watermark_scale_factor to reduce stalls and compactions
the high mark is also changed, it changed a bit too much. So this
patch introduces a slope that can reduce this overhead a bit, or

To be compatible with legacy device, reset the addressing mode
to the default mode. Such as Freescale eSPI boot, it copies the

It's a bugfix for an issue if PAGE_POISONING is enabled in the kernel

Add 'component' directory to debugfs. Create a new file for each master,
when a master is added. Remove it on a master deletion.
Show a list of devices matched with master and indicate if
master's components were successfully added and if the whole master is
bound.
