Am seeing a build error in next-0514. -0420 built OK.
building a 'make allmodconfig' on a RPi4 in 32-bit mode.
MODPOST 7575 modules
ERROR: modpost: "__aeabi_uldivmod" [drivers/md/dm-zoned.ko] undefined!
objdump and 'make drivers/md/dm-zoned-target.s' tells
me that the problem is in function dmz_fixup_devices(), near here:
@ drivers/md/dm-zoned-target.c:806: reg_dev->nr_zones = DIV_ROUND_UP(reg_dev->capacity,

git blame points at this commit:
commit 70978208ec91d798066f4c291bc98ff914bea222
Author: Hannes Reinecke <hare@suse.de>
Date: Mon May 11 10:24:30 2020 +0200
dm zoned: metadata version 2
Reverting that commit lets the build complete.

That's because the DIV_ROUND_UP in the patch should actually be
DIV_ROUND_UP_SECTOR_T I think.

I thought I've send a patch to fix that up; DIV_ROUND_UP() needs to be
changed to DIV_ROUND_UP_ULL().
I'll be checking and will be sending a patch if necessary.

Unless I'm missing something it was fixed up with this commit last
wednesday (13th):
