I have two patches, one to change the interface with no functional change (PATCH 1) and one to fix the problem (PATCH 2). Moreover they don't cover the same subsystems. I can either: - merge the two patches - or make a reference in the changelog of PATCH 1 to PATCH 2 (something like "(see folowing patch "powerpc/pseries: pass MSI affinity to irq_create_mapping()")") - or copy some information from PATCH 2 (something like "this parameter is needed by rtas_setup_msi_irqs() to pass the affinity to irq_domain_alloc_descs() to fix multiqueue affinity") What do you prefer? Thanks, Laurent
