Hi All,

As discussed here in the v1 thread:
https://lore.kernel.org/linux-acpi/20230806151453.10690-1-hdegoede@redhat.com/

Here is a v2 which adds a few fixes on top of the revert
to avoid the revert causing regressions on AMD Zen systems
where dropping the special Zen behavior was known to fix
things.

As also mentioned in the thread this is intended as a short term fix
for 6.4.y >= 6.4.7 and 6.5 to get all the systems which were working
fine before commit a9c4a912b7dc ("ACPI: resource: Remove "Zen"
specific match and quirks") to work again.

The long term plan is to see if we can read back what the BIOS
has actually programmed as IRQ trigger-type / polarity into
the IOAPIC.

Regards,

Hans
