This series of patches are follow up work (and depends on)
Toshi Kani <toshi.kani@xxxxxxx>'s patches "fix memory leak/
panic in ioremap huge pages".

This series of patches are tested on 4.9 kernel with Cortex-A75
based SoC.

Given that this is targeting mainline, can you please test with 4.16?
Basing your patches on something that is over 15 months old is not
exactly reassuring.

We have 4.14 ported with the devices (remotely) accessible to me. If
that's sufficient, I will post test report by tomorrow.

If we really require these patches to be tested with 4.16, I would need
some help here.

Rajendra Nayak <rnayak@xxxxxxxxxxxxxx> helped me with testing these
patches on 4.16 kernel (with all the dependent patches already part of
4.16) on SDM845.

In addition to kernel boot up, he executed my test-code which was
stressing ioremap framework and was able to reproduce the bug without
these patches (and Will Deacon's WA).

That passed 10hrs of run.

[36001.446355] IOREMAP_TEST: my tests ended now

Thanks Rajendra Nayak for testing these patches.

Thanks,


Thanks,
