Today's -next (and at least back to Friday, older logs are unclear - I
only noticed -next issues today) fails to NFS boot on an AT91SAM9G20-EK
(an old ARMv5 platform) with multi_v5_defconfig, a bisect appears to
point to this patch (20aae9eff5acd8f5 in today's -next) as the culprit.

It's been in -next for quite a while, thanks for the report!

Yeah, there's been some other things obscuring the issue.

Could you give the following a test?

Subject: [PATCH] arm/mm: Fix swp type masking in __swp_entry()

We're masking with the number of type bits instead of the type mask, which
is obviously wrong.

Tested-by: Mark Brown <broonie@kernel.org>

but note that I had to manually apply it, though it's pretty trivial so
I probably applied the right thing.
