Re: [PATCH v10 07/12] cxl: Validate HDM ranges before CXL reset

> Before reset, require cached HDM decoder state, collect enabled decoder
> ranges, and reserve them with request_mem_region(). This rejects reset
> while affected CXL memory is busy and keeps the validation stable
> through reset.
> 
> If CPU cache invalidation support is available, invalidate the affected
> ranges before reset. If the runtime backend is unavailable, continue
> after the range reservation succeeds.
> 
> Reject CXL Reset when no cached HDM decoder state is available. The reset
> path needs the cached address map to validate affected ranges and perform
> CPU cache invalidation. Also reject normalized-addressing decoders for
> now because the cached decoder range is not a system physical address.
