2011-04-15	More than a decade ago, interrupt handlers on sparc started returning 0	Theo de Raadt
	(interrupt was not for me), 1 (positive interrupt was for me), or -1 (i am not sure...). We have continued with this practice in as many drivers as possible, throughout the tree. This makes some of the architectures use that information in their interrupt handler calling code -- if 1 is returned (and we know this specific machine does not have edge-shared interrupts), we finish servicing other possible handlers on the same pin. If the interrupt pin remains asserted (from a different device), we will end up back in the interrupt servicing code of course... but this is cheaper than calling all the chained interrupts on a pin. This does of course count on shared level interrupts being properly sorted by IPL. There have been some concerns about starvation of drivers which incorrectly return 1. Those drivers should be hunted down so that they return -1. (other architectures will follow) ok kettenis drahn dlg miod

	hierarchy. Everything attached to a single root node anyway, so at best we had a bush. "i think it is good" deraadt@
2009-09-30	Remove unused last argument of alpha_shared_intr_disestablish().	Miod Vallat

2006-06-15	Rework the interrupt code, shaving some cycles off in the process.	Brad Smith
	Rather than an "iointr" routine that decomposes a vector into an IRQ, we maintain a vector table directly, hooking up each "iointr" routine at the correct vector. This also allows us to hook device interrupts up to specific vectors. From thorpej NetBSD Tested by myself and a number of end-users.
2006-01-29	Add a alpha_shared_intr_reset_strays() function that resets the stray	Martin Reindl
	interrupt counter for a given shared interrupt descriptor. When an interrupt is successfully handled, reset the strays counter, thus preventing a "slow leak" from eventually shutting off the interrupt vector. from NetBSD via KUDO Takashi
2004-12-25	Use list and queue macros where applicable to make the code easier to read;	Miod Vallat
	no functional change.

2002-03-14	First round of __P removal in sys	Todd C. Miller

2001-06-25	cold is in systm now	Michael Shalayeff

2000-11-08	tag the rest of alpha tree	Eric Jackson

2000-11-08	Merge in big portions of the improvements NetBSD did to their alpha port.	Artur Grabowski
	Highlights: UVM, PMAP_NEW, bus_dma (only on some buses for now), new hardware support, possiblity for ELF, etc, etc. Too much to mention. This is still work in progress. video consoles might be broken, otherwise we have basically the same functionality as before plus more.
