| Subject | linux-next: build warning after merge of the powerpc tree |
| Message-ID | <qlxEJ-2u7-5@gated-at.bofh.it> |
Hi all,
After merging the powerpc tree, today's linux-next build (powerpc
allyesconfig) produced this warning:
WARNING: vmlinux.o(.text+0x9367c): Section mismatch in reference from the function .msi_bitmap_alloc() to the function .init.text:.memblock_virt_alloc_try_nid()
The function .msi_bitmap_alloc() references
the function __init .memblock_virt_alloc_try_nid().
This is often because .msi_bitmap_alloc lacks a __init
annotation or the annotation of .memblock_virt_alloc_try_nid is wrong.
Introduced (probably) by commit
cb2d3883c603 ("powerpc/msi: Free the bitmap if it was slab allocated")

Cheers,

Yeah that's correct, though it should be safe in practice.
I'm not sure why you only saw that now though, the patch has been in next since
the 13th of October.
cheers

I don't always notice new warnings immediately among all the others :-(
