Dave Jiang 8c41d72e69 cxl: Fix the incorrect assignment of SSLBIS entry pointer initial location ... [ Upstream commit 99b52aac2d ] The 'entry' pointer in cdat_sslbis_handler() is set to header + sizeof(common header). However, the math missed the addition of the SSLBIS main header. It should be header + sizeof(common header) + sizeof(*sslbis). Use a defined struct for all the SSLBIS parts in order to avoid pointer math errors. The bug causes incorrect parsing of the SSLBIS table and introduces incorrect performance values to the access_coordinates during the CXL access_coordinate calculation path if there are CXL switches present in the topology. The issue was found during testing of new code being added to add additional checks for invalid CDAT values during CXL access_coordinate calculation. The testing was done on qemu with a CXL topology including a CXL switch.
