While trying to understand internals of irq handling, came across a thread [1] in which tglx was referring to avoid usage of setup_irq(). Existing callers of setup_irq() reached mostly via 'init_IRQ()' & 'time_init()', while memory allocators are ready by 'mm_init()'. Hence instances of setup_irq() is replaced by request_irq() & setup_irq() (along with remove_irq()) definition deleted in the last patch. Seldom remove_irq() usage has been observed coupled with setup_irq(), wherever that has been found, it too has been replaced by free_irq().
thanks a lot for tackling this! Vs. merging this series, I suggest the following approach: - Resubmit the individual changes as single patches or small series to the relevant maintainers and subsystem mailing lists. They have no dependency on a core change and can be applied where they belong to. - After 5.6-rc6, verify which parts have made their way into linux-next and resubmit the ignored ones as a series to me along with the removal of the core parts. That way we can avoid conflicting changes between subsystems and the tip irq/core branch as much as possible. Thanks, tglx
