Here's a set of patches that annotate module parameters that configure
hardware resources including ioports, iomem addresses, irq lines and dma
channels.

This will be used in a future patch to prohibit the use of such module
parameters so that hardware can't be abused to gain access to the running
kernel image.

This is done by changing:

module_param(n, t, p)
module_param_named(n, v, t, p)
module_param_array(n, t, m, p)

to:

module_param_hw(n, t, hwtype, p)
module_param_hw_named(n, v, t, hwtype, p)
module_param_hw_array(n, t, hwtype, m, p)

where hwtype specifies the type of the resource being configured.

Note that the hwtype is compile checked, but not currently stored (the
lockdown code probably won't require it). It is, however, there for future
use.

The patches can be found here also:
