Hi Andrew,
After merging the akpm-current tree, today's linux-next build (x86_64
allmodconfig) failed like this:
drivers/vfio/vfio_iommu_type1.c: In function 'vaddr_get_pfn':
drivers/vfio/vfio_iommu_type1.c:364:9: error: too few arguments to function 'get_user_pages_remote'
ret = get_user_pages_remote(NULL, mm, vaddr, 1, flags, page,

Caused by commit
d6c547ad0c61 ("mm: add locked parameter to get_user_pages_remote()")
interacting with commit
ea85cf353e4f ("vfio iommu type1: Update argument of vaddr_get_pfn()")
from the vfio tree.
I applied this merge fix patch:
