Hello Wei,

Starting with next-20200122, I'm seeing the following in KMSG on NVIDIA
Tegra (ARM32):

  BUG: Bad rss-counter state mm:(ptrval) type:MM_ANONPAGES val:190

and eventually kernel hangs.

Git's bisection points to this patch and reverting it helps. Please fix,
thanks in advance.

Thanks.  I had these tagged for 5.7-rc1 anyway, so I'll drop all five
patches.

Hello Andrew,

FYI, I'm still seeing the offending patches in the today's next-20200129.

hm, me too.  Stephen, it's unexpected that 9ff4452912d63f ("mm/mremap:
use pmd_addr_end to calculate next in move_page_tables()") is still in
the -next lineup?  It was dropped from -mm on Jan 26?
