Ian Munsie eb01d4c238 cxl: Fix PSL error due to duplicate segment table entries ... In certain circumstances the PSL (Power Service Layer, which provides translation services for CXL hardware) can send an interrupt for a segment miss that the kernel has already handled. This can happen if multiple translations for the same segment are queued in the PSL before the kernel has restarted the first translation. The CXL driver does not expect this situation and does not check if a segment had already been handled. This could cause a duplicate segment table entry which in turn caused a PSL error taking down the card. This patch fixes the issue by checking for existing entries in the segment table that match the segment we are trying to insert, so as to avoid inserting duplicate entries.
