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")

[ Upstream commit f6794950f0e5ba37e3bbedda4d6ab0aad7395dd3 ]
filter_irq_stacks() is supposed to cut entries which are related irq entries from its call stack. And in_irqentry_text() which is called by filter_irq_stacks() uses __irqentry_text_start/end symbol to find irq entries in callstack.
But it doesn't work correctly as without "CONFIG_FUNCTION_GRAPH_TRACER", arm64 kernel doesn't include gic_handle_irq which is entry point of arm64 irq between __irqentry_text_start and __irqentry_text_end as we discussed in below link. https://lore.kernel.org/all/CACT4Y+aReMGLYua2rCLHgFpS9io5cZC04Q8GLs-uNmrn1ez...
This problem can makes unintentional deep call stack entries especially in KASAN enabled situation as below.

[ Upstream commit ab9b4008092c86dc12497af155a0901cc1156999 ]
Both create_mapping_noalloc() and update_mapping_prot() sanity-check their 'virt' parameter, but the check itself doesn't make much sense. The condition used today appears to be a historical accident.
The sanity-check condition:
if ((virt >= PAGE_END) && (virt < VMALLOC_START)) { [ ... warning here ... ] return; }
... can only be true for the KASAN shadow region or the module region, and there's no reason to exclude these specifically for creating and updateing mappings.
When arm64 support was first upstreamed in commit:
c1cc1552616d0f35 ("arm64: MMU initialisation")
... the condition was:
if (virt < VMALLOC_START) { [ ... warning here ... ] return; }
At the time, VMALLOC_START was the lowest kernel address, and this was checking whether 'virt' would be translated via TTBR1.
Subsequently in commit:
14c127c957c1c607 ("arm64: mm: Flip kernel VA space")
... the condition was changed to:
if ((virt >= VA_START) && (virt < VMALLOC_START)) { [ ... warning here ... ] return; }
This appear to have been a thinko. The commit moved the linear map to the bottom of the kernel address space, with VMALLOC_START being at the halfway point. The old condition would warn for changes to the linear map below this, and at the time VA_START was the end of the linear map.
Subsequently we cleaned up the naming of VA_START in commit:
77ad4ce69321abbe ("arm64: memory: rename VA_START to PAGE_END")
... keeping the erroneous condition as:
if ((virt >= PAGE_END) && (virt < VMALLOC_START)) { [ ... warning here ... ] return; }
Correct the condition to check against the start of the TTBR1 address space, which is currently PAGE_OFFSET. This simplifies the logic, and more clearly matches the "outside kernel range" message in the warning.
