cmd_alloc can no longer return NULL, so don't check for NULL any more

Hi ,
I need some suggestion .
From the below interrupt handler in libahci.c it explains that the
interrupt from port to Host is level triggered. Do we have any
existing implementation that handles the port to Host as Edge
triggered.
Not that I know of but if it works as a edge triggered
This patch changes the !blk-mq path to the same defaults as the blk-mq
I/O path by always enabling block tagging, and always using host wide
tags. We've had blk-mq available for a few releases so bugs with
this mode should have been ironed out, and this ensures we get better
coverage of over
The first 5 patches move the magic IDE request types into the old IDE
driver to keep the core block code clean of them. Those are basically
ready to merge, just like the 6th one which is a cleanup on it's own.
The real RFC is the last one which allocates the block_pc specific
data separately in

This removes the request types and hacks from the block code and into the
old IDE driver. There is a small amunt of code duplication due to this,
but it's not too bad.

These values are only used by the IDE driver, so move them into it
by allowing drivers to take cmd_type values after the first private
one. Note that we have to turn cmd_type into a plain unsigned integer
so that gcc doesn't complain about mismatching enum types.
