Hi reviewers,
I suggest to apply the following patch to stable kernel 5.4.y and 5.10.y:
commit: 5b61343b50590fb04a3f6be2cdc4868091757262
Subject: iommu/iova: Improve 32-bit free space estimate
kernel version to apply to: 5.4.y and 5.10.y
Reason:
The patch fix a corner case of iova allocation and the allocation failure
can be found under stress tests.
Test:
The patch can be applied to Linux 5.10.109 and Linux 5.4.188 without conflicts.
Both Linux 5.10.109 and Linux 5.4.188 can be built successfully with
this patch. (ARCH=arm64 defconfig)
Thanks,
Miles

What about 5.15 and 5.16 and 5.17? Why skip them?

Sorry for missing that, please add them to 5.15, 5.16 and 5.17. (I saw
you already added them, thanks).
I tested the patch(no merge conflict) and buld with Linux 5.15.32,
Linux 5.17.1, and Linux 5.16.18
Thanks,
Miles
