Now based on master as precursors merged. Before pushing on to more significant features a few unrelated patches doing tidying up + one to avoid people setting the memory backend both for a CXL type 3 device and as normal RAM in an attempt to get SRAT to cover it correctly. We've had multiple 'bug' reports from this and if nothing else I'd like to stop getting those!

I was also holding back series that were less critical for kernel testing to make sure they didn't distract from the progress of Dynamic Capacity. This 1st series includes a couple of more general improvements that interact closely with the scan media changes. This series applies directly on master and can go in parallel to [PATCH qemu v2 0/3] hw/cxl: Misc minor improvements The Scan Media commands enable recovery from the situation where a poison list has overflowed and the OS has no other way to find out which memory is bad, or because the user wants force a recheck for uncorrectable ECC errors. This functionality is emulated by keeping an additional list of injected poison that is not exposed via the existing get poison list command. This list is 'discovered' during processing of Scan Media as if the hardware had detected these errors in real memory.

A couple of white space fixes (checkpatch) This one was waiting on a v3 revision from Davildlohr (which he posted last week) rather than DCD as such, but the various series before this one cause a lot of churn so it's easier to merge in this order. Details in patch 1, but in short this fakes firmware updates, allowing testing of the OS support.
