And I've just noticed that I've messed up the subject of the cover letter.
There are 26 patches, not 27. So it should have been 00/26 not 00/27.

The VFIO reset hook is called every time a platform device is passed
to a guest or removed from a guest.
When the XHCI device is unbound from the host, the host driver
disables the XHCI clocks/phys/regulators so when the device is passed
to the guest it becomes dis-functional.

Some UDF creators (specifically Microsoft, but perhaps others) mishandle
the ECMA-167 corner case that requires descriptors within a Volume
Recognition Sequence to be placed at 4096-byte intervals on media where
the block size is 4K. Instead, the descriptors are placed at the 2048-
byte interval ma
Extract code that parses a Volume Recognition Sequence descriptor
(component), in preparation for calling it twice against different
locations in a block.

The module reset code in the Renesas CPG/MSSR driver uses

more information to
debug this.
I also get a ton of objtool warnings building random configurations, but Nick
mentioned that there is still a bug related to asm
