Subject: ARC: mm: HIGHMEM: Fix section mismatch splat
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=899cfd2bb0d1953d78d14d5e912e13b8bd92a58f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARC: mm: HIGHMEM: Fix section mismatch splat

| WARNING: vmlinux.o(.text+0xd6c2): Section mismatch in reference from the function alloc_kmap_pgtable() to the function
| .init.text:__alloc_bootmem_low()
The function alloc_kmap_pgtable() references the function __init __alloc_bootmem_low().
This is often because alloc_kmap_pgtable lacks a __init annotation or the annotation of __alloc_bootmem_low is wrong.
