Allow zcache to be built/loaded as a module. Note runtime dependency
disallows loading if cleancache/frontswap lazy initialization patches
are not present. Zsmalloc support has not yet been merged into zcache
but, once merged, could now easily be selected via a module_param.
If built-in (not built as a module), the original mechanism of enabling
via a kernel boot parameter is retained, but this should be considered
deprecated.
Note that module unload is explicitly not yet supported.

COMEDI_PCI_DRIVERS section of the Kconfig. This means that PCI support
must be enabled in order to use the ni_labpc driver for the PCI or
PCMCIA drivers.
Split the PCI support code out of the ni_labpc driver into a separate
driver, ni_labpc_pci. The PCMCIA support is already slip out as
ni_labpc_cs.
Modify the Kconfig so that the common code in ni_labpc is enabled by the
Kconfig option COMEDI_NI_LABPC. The ISA support code is currently still
in the ni_labpc driver but is only compiled in if COMEDI_NI_LABPC_ISA is
also enabled.
This allows the PCI and PCMCIA drivers to be enabled without the need
