>> WARNING: modpost: vmlinux.o(.text.unlikely+0x1b81a): Section mismatch in reference from the function get_secrets_page() to the function .init.text:early_memremap()
The function get_secrets_page() references
the function __init early_memremap().
This is often because get_secrets_page lacks a __init
annotation or the annotation of early_memremap is wrong.
