Here is a new version of the patch to support the Automata Sercos III PCI card driver. I now check that the IRQ is enabled before accepting the interrupt. I still use a logical OR to store the enabled interrupts and I've added a second use of a logical OR when restoring the enabled interrupts. I added an explanation of why I do this in comments at the top of the source file. Since I use a logical OR, I also removed the extra checks if the Interrupt Enable Register and ier0_cache are 0.

Enable this to allow the userspace driver core code to be

built. This code allows userspace programs easy access to

kernel interrupts and memory locations, allowing some drivers

to be written in userspace. Note that a small kernel driver

is also required for interrupt handling to work properly.

Platform driver for Userspace I/O devices, including generic

interrupt handling code. Shared interrupts are not supported.

This kernel driver requires that the matching userspace driver

handles interrupts in a special way. Userspace is responsible
|

for acknowledging the hardware device if needed, and re-enabling

interrupts in the interrupt controller using the write() syscall.
