For v5.0-rc1-1-g3bd6e94bec12:

Build results:
	total: 158 pass: 155 fail: 3
Failed builds: 
	csky:defconfig 
	csky:allnoconfig
	csky:tinyconfig 
Qemu test results:
	total: 332 pass: 332 fail: 0

mm/memory.c: In function ‘__pte_alloc’:
mm/memory.c:406:18: error: too few arguments to function ‘pte_alloc_one’

mm/memory.c: In function ‘__pte_alloc_kernel’:
mm/memory.c:439:15: error: too few arguments to function ‘pte_alloc_one_kernel’

mm/memory.c: In function ‘do_fault_around’:
mm/memory.c:3363:23: error: too few arguments to function ‘pte_alloc_one’

Bisect points to commit 4cf58924951ef ("mm: treewide: remove unused address
argument from pte_alloc functions"). Interesting - wasn't that supposed
to be automatic ?

csky does use the the removed address argument, so I won't even try to
provide a patch. Copying csky maintainer instead.
