[RFC,V2,27/45] xen/sched: switch sched_move_irqs() to take sched_item as parameter

Commit Message

Jürgen Groß May 6, 2019, 6:56 a.m. UTC

sched_move_irqs() should work on a sched_item as that is the item
moved between cpus.

Rename the current function to vcpu_move_irqs() as it is still needed
in schedule().
