commit 9946e39fe8d0 ("ACPI: resource: skip IRQ override on
AMD Zen platforms") attempted to overhaul the override logic so it
didn't apply on X86 AMD Zen systems. This was intentional so that
systems would prefer DSDT values instead of default MADT value for
IRQ 1 on Ryzen 6000 systems which typically uses ActiveLow for IRQ1.
This turned out to be a bad assumption because several vendors
add Interrupt Source Override but don't fix the DSDT. A pile of
quirks was collecting that proved this wasn't sustaintable.
Furthermore some vendors have used ActiveHigh for IRQ1.
To solve this problem revert the following commits:
* commit 17bb7046e7ce ("ACPI: resource: Do IRQ override on all TongFang
GMxRGxx")
* commit f3cb9b740869 ("ACPI: resource: do IRQ override on Lenovo 14ALC7")
* commit bfcdf58380b1 ("ACPI: resource: do IRQ override on LENOVO IdeaPad")
* commit 7592b79ba4a9 ("ACPI: resource: do IRQ override on XMG Core 15")
* commit 9946e39fe8d0 ("ACPI: resource: skip IRQ override on AMD Zen
platforms")

v2->v3:
* Adjust to drop heuristics entirely
* Drop tested tags
* Add more links and people to Cc
* Drop Fixes tag as this got a lot more risky
v1->v2:
* Rebase on 71a485624c4c ("ACPI: resource: Add IRQ override quirk for LG UltraPC 17U70P")
* Pick up tag
Rafael,
Please hold off on picking this up until the majority of those on CC
have tested it on hardware they have and reported results.
Everyone else,
Please test. If you have problems with this applied, please share
an acpidump and dmesg either on a bug or to me privately.
