Yes, I just tested this patch, and everything seems to work fine. Thank you. :)
The only point I see, which is not triggered on my machine (because of the absence of ACPI) is this one :
There is also an initialization of this mp_irqs variable in mp_config_acpi_legacy_irqs from mpparse.c. It only seems to be called from within acpi_boot_init in acpi.c. So I wonder if it's possible that we do use default configuration and then also go into mp_config_acpi_legacy_irqs during the acpi init, thus reserving the memory twice and forgetting the old pointer, which could lead to an erratic result.
If it's possible, then there is still a problem in there.
