The io-pgtable code constructs an array of init functions for each
page table format at compile time. This is not ideal, as it prevents
io-pgtable formats from being built as kernel modules.

dynamic registration scheme, where

The goal of the Generic Kernel Image (GKI) effort is to have a common
kernel image that works across multiple Android devices. This involves
generating a kernel image that has core features integrated into it,
while SoC specific functionality can be added to the kernel for the
device as a module.

When irq_domain_get_irq_data() or irqd_cfg() fails
at i == 0, data allocated by kzalloc() has not been
freed before returning, which leads to memleak.

The AMD IOMMU initialisation registers the IRQ remapping domain for
each IOMMU before doing the final sanity check that every I/OAPIC is
covered.
This means that the AMD irq_remapping_select() function gets invoked
even when IRQ remapping has been disabled, eventually

When I made the INTCAPXT support stop gratuitously pretending to be MSI,
I missed the fact that iommu_setup_msi() also sets the ->int_enabled
flag. I missed this in the iommu_setup_intcapxt() code path, which means
that a resume from suspend will try to allocate the IRQ

Hi folks,
syscore_resume() doesn't like when the AMD iommu driver enables
interrupts in its ->resume hook when I resume the box from suspend to
RAM.
All kinds of warnings get triggered too:
