Hi all,
After merging the akpm tree, today's linux-next build (sparc defconfig)
failed like this:
In file included from arch/sparc/include/asm/pgtable.h:7:0,
from include/linux/pgtable.h:6,
from include/linux/mm.h:33,
from include/linux/ring_buffer.h:5,
from include/linux/trace_events.h:6,

from include/linux/syscalls.h:87,
from fs/io_uring.c:45:
arch/sparc/include/asm/pgtable_32.h: In function 'pud_pgtable':
arch/sparc/include/asm/pgtable_32.h:157:10: warning: return makes pointer from integer without a cast [-Wint-conversion]
return ~0;
^
and many, many more like this.
This is an error due to (part of) the tree being built with -Werror
Caused by commit
8aef6710db27 ("mm: rename pud_page_vaddr to pud_pgtable and make it return pmd_t *")
I have applied the following hack fix for today.
