Hi all,
After merging the akpm-current tree, today's linux-next build (sparc
defconfig) failed like this:
In file included from include/linux/mm.h:32:0,
from include/linux/memblock.h:13,
from arch/sparc/mm/srmmu.c:14:
include/linux/pgtable.h:74:27: error: redefinition of 'pte_offset_kernel'

Caused by commit
292aa65ed13a ("mm: consolidate pte_index() and pte_offset_*() definitions")
I used the (missing part of the) patch from next-20200608:
