The patch titled
genirq: msi: refactor the msi_ops
has been added to the -mm tree. Its filename is
genirq-msi-refactor-the-msi_ops.patch
See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find
out what to do about this
------------------------------------------------------
Subject: genirq: msi: refactor the msi_ops
From: "Eric W. Biederman" <ebiederm@xxxxxxxxxxxx>
The current msi_ops are short sighted in a number of ways, this patch attempts
to fix the glaring deficiences.
- Report in msi_ops if a 64bit address is needed in the msi message, so we
can fail 32bit only msi structures.
- Send and receive a full struct msi_msg in both setup and target. This is
a little cleaner and allows for architectures that need to modify the data
to retarget the msi interrupt to a different cpu.
- In target pass in the full cpu mask instead of just the first cpu in case
we can make use of the full cpu mask.
- Operate in terms of irqs and not vectors, currently there is still a 1-1
relationship but on architectures other than ia64 I expect this will change.
