swiotlb fixes for 5.15.y

[Public]

Hi,

A patch series of 7 swiotlb fixes was accepted into 5.16. This series is needed to prevent warnings from swiotlb when hotplugging untrusted NVME devices on 5.15.y.

The first 2 commits are already applied in 5.15.y. The last 5 are still needed.  Can you please backport these to 5.15.y as well?

commit ee9d4097cc145dcaebedf6b113d17c91c21333a0 commit 9b49bbc2c4dfd0431bf7ff4e862171189cf94b7e commit 2e727bffbe93750a13d2414f3ce43de2f21600d2 commit e81e99bacc9f9347bda7808a949c1ce9fcc2bbf4 commit 2cbc61a1b1665c84282dbf2b1747ffa0b6248639

With the whole series the warnings are gone.

Thanks,
