[PATCH] genirq: msi: refactor the msi_ops
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.
