Subject: [RFC 6/6] pci: hotplug: move cardbus code from drivers/pcmcia
From: Arnd Bergmann <arnd@...db.de>
16-bit pcmcia and 32-bit cardbus code are now completely separate
code bases, with the cardbus implementation just interfacig with
the PCI core for hotplugging cards, so move it to the same place
as the other PCI hotplug drivers.
The pcmcia/i82365.h header file is the only bit that contains shared
definitions for common registers.
