[PATCH] ULI 2.6.12

[Michael Raymond <mraymond@sgi.com>]

    Here's a patch of the ULI code to Tony's pre-2.6.12 tree.
Signed-off-by: Michael A Raymond <mraymond@sgi.com>

    I was able to show that ULIs cannot be scheduled onto other CPUs.  For
every IRQ that a user requests it registers a standard handler.  All IRQ
handlers are called out of do_IRQ().  It's not until do_IRQ() is called that
ia64_eoi() is called to complete the ACK and allow lower priority interrupts
into the system.
    I've added a simple stats program that makes use of ULIs to the support
package on the web site (1).  We've also found a case where their low
perturbation will be useful for user level profiling. I'll be writing that
up next.
     	     					Thanks,
