In a gcc-11 randconfig build I came across this warning:

WARNING: modpost: vmlinux.o(.text.unlikely+0x2c084): Section mismatch in reference from the function next_platform_timer() to the variable .init.data:acpi_gtdt_desc
The function next_platform_timer() references
the variable __initdata acpi_gtdt_desc.
This is often because next_platform_timer lacks a __initdata
annotation or the annotation of acpi_gtdt_desc is wrong.

This happens when next_platform_timer() fails to get inlined
despite the inline annotation. Adding '__init' solves the issue,
and it seems best to remove the 'inline' in the process seems
better anyway.

There was a patch to fix this issue as well [1],
but not merged yet.

Right, either of those patches should be fine.

Rafael, can you pick one of them up?
