The patch titled
Initial generic hypertransport interrupt support
has been removed from the -mm tree. Its filename is
initial-generic-hypertransport-interrupt-support.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Initial generic hypertransport interrupt support
From: Eric W. Biederman <ebiederm@xxxxxxxxxxxx>
This patch implements two functions ht_create_irq and ht_destroy_irq for
use by drivers. Several other functions are implemented as helpers for
arch specific irq_chip handlers.
The driver for the card I tested this on isn't yet ready to be merged.
However this code is and hypertransport irqs are in use in a few other
places in the kernel. Not that any of this will get merged before 2.6.19
Because the ipath-ht400 is slightly out of spec this code will need to be
generalized to work there.
I think all of the powerpc uses are for a plain interrupt controller in a
chipset so support for native hypertransport devices is a little less
interesting.
However I think this is a half way decent model on how to separate arch
specific and generic helper code, and I think this is a functional model of
how to get the architecture dependencies out of the msi code.
