[PATCH] htirq: tidy up the htirq code
This moves the declarations for the architecture helpers into include/linux/htirq.h from the generic include/linux/pci.h. Hopefully this will make this distinction clearer. htirq.h is included where it is needed. The dependency on the msi code is fixed and removed. The Makefile is tidied up. Signed-off-by: Eric W.
