I hope nVidia will finish it and fix the initial problem sooner than later. Bart, Linus, First 4 patches may be directly applied to the tree (they are at least compile-tested, but I believe they won't change any functionality. Patch 5 is some stubs that should have been done in the driver. Patch 6 is follow up removal of custom GPIO IRQ handling from Mellanox GBE driver. Both of them are quite far from finishing, but it's a start for nVidia to develop and test proper solution. In any case, I will probably sent end this week the ACPI IRQ abuse part from the GBE driver (I won't touch OF path). ARs for nVidia: 0) review this series; 1) properly develop GPIO driver; 2) replace custom code with correct one; 3) send the work for review to GPIO and ACPI maintainers (basically list of this series). On my side I will help you if you have any questions regarding to GPIO and ACPI.
