These API need to bypass the acpi_irq_get_penalty function.
I don't mind this patch, but the changelog doesn't tell me what's
broken and why we need this fix.  Apparently acpi_irq_get_penalty()
doesn't work before ACPI is initialized, but I don't see *why* it
wouldn't work.
I'll update the commit message as you suggested. The code doesn't work
if we apply PATCH V4 2/3 + PATCH V4 3/3 without PATCH V4 1/3 since
the caller is going to end up calling get_penalty function while ACPI
is not initialized. This happened during the debug of this regression.
