Hi Andrew,
After merging the akpm tree, today's linux-next build (sparc64 defconfig)
failed like this:
arch/sparc/kernel/mdesc.c: In function 'mdesc_kmalloc':
arch/sparc/kernel/mdesc.c:208:48: error: '__GFP_REPEAT' undeclared (first use in this function)
base = kmalloc(handle_size + 15, GFP_KERNEL | __GFP_REPEAT);
^
Caused by commit
726ad49b664b ("mm, tree wide: replace __GFP_REPEAT by __GFP_RETRY_MAYFAIL with more useful semantic")
interacting with commit
0ab2fcd69dbf ("sparc64: mdesc: use __GFP_REPEAT action modifier for VM allocation")
from the sparc-next tree.
For now I have applied the following (I expect it to be replaced with
something better):
