[PATCH 0/3] Improve robustness of NVMe suuport for Apple silicon devices

[Janne Grunau]

Hej,

this series has assorted fixes to improve the robustness of the NVMe
support on Apple silicon devices. The main change which prompted this
series is "rm: apple: nvme: Add SART support and RTKit buffer
management". It fixes the RTKit driver required for the NVMe with the
system-wide firmware included in the first macOS 13 beta release.

The increased timeouts in RTKit are a defensive change against future
changes. None of the mailbox receive calls is expected to timeout so
waiting up to 1 second for a fatal error seems acceptable.

cheers Janne
