efx_net_stats() (.ndo_get_stats64) can be called during an ethtool selftest, during which time nic_data->mc_stats is NULL as the NIC has been fini'd.

2023-06-26iscsi_ibft: Fix finding the iBFT under Xen Dom 0Ross Lagerwall
To facilitate diskless iSCSI boot, the firmware can place a table of configuration details in memory called the iBFT. The presence of this table is not specified, nor is the precise location (and it's not in the E820) so the kernel has to search for a magic marker to find it. When running under Xen, Dom 0 does not have access to the entire host's memory, only certain regions which are identity-mapped which means that the pseudo-physical address in Dom0 == real host physical address. Add the iBFT search bounds as a reserved region which causes it to be identity-mapped in xen_set_identity_and_remap_chunk() which allows Dom0 access to the specific physical memory to correctly search for the iBFT magic marker (and later access the full table). This necessitates moving the call to reserve_ibft_region() somewhat later so that it is called after e820__memory_setup() which is when the Xen identity mapping adjustments are applied. The precise location of the call is not too important so I've put it alongside dmi_setup() which does similar scanning of memory for configuration tables. Finally in the iBFT find code, instead of using isa_bus_to_virt() which doesn't do the right thing under Xen, use early_memremap() like the dmi_setup() code does. The result of these changes is that it is possible to boot a diskless Xen + Dom0 running off an iSCSI disk whereas previously it would fail to find the iBFT and consequently, the iSCSI root disk.

2023-06-26powerpc/iommu: TCEs are incorrectly manipulated with DLPAR add/remove of memoryGaurav Batra
When memory is dynamically added/removed, iommu_mem_notifier() is invoked. This routine traverses through all the DMA windows (DDW only, not default windows) to add/remove "direct" TCE mappings. The routines for this purpose are tce_clearrange_multi_pSeriesLP() and tce_clearrange_multi_pSeriesLP(). Both these routines are designed for Direct mapped DMA windows only. The issue is that there could be some DMA windows in the list which are not "direct" mapped. Calling these routines will either, 1) remove some dynamically mapped TCEs, Or 2) try to add TCEs which are out of bounds and HCALL returns H_PARAMETER Here are the side affects when these routines are incorrectly invoked for "dynamically" mapped DMA windows. tce_setrange_multi_pSeriesLP() This adds direct mapped TCEs. Now, this could invoke HCALL to add TCEs with out-of-bound range. In this scenario, HCALL will return H_PARAMETER and DLAR ADD of memory will fail. tce_clearrange_multi_pSeriesLP() This will remove range of TCEs. The TCE range that is calculated, depending on the memory range being added, could infact be mapping some other memory address (for dynamic DMA window scenario). This will wipe out those TCEs. The solution is for iommu_mem_notifier() to only invoke these routines for "direct" mapped DMA windows.

Pick up the driver cleanups identified in preparation for CXL "type-2" (accelerator) device support. The major change here from a conflict generation perspective is the split of 'struct cxl_memdev_state' from the core 'struct cxl_dev_state'. Since an accelerator may not care about all the optional features that are standard on a CXL "type-3" (host-only memory expander) device. A silent conflict also occurs with the move of the endpoint port to be a formal property of a 'struct cxl_memdev' rather than drvdata.

2023-06-25Merge branch 'for-6.5/cxl-fwupd' into for-6.5/cxlDan Williams
Add the first typical (non-sanitization) consumer of the new background command infrastructure, firmware update. Given both firmware-update and sanitization were developed in parallel from the common background-command baseline, resolve some minor context conflicts.

2023-06-25Merge branch 'for-6.5/cxl-background' into for-6.5/cxlDan Williams
Pick up the sanitization work and the infrastructure for other background commands for 6.5. Sanitization has a different completion path than typical background commands so it was important to have both thought out and implemented before either went upstream.
2023-06-25tools/testing/cxl: add firmware update emulation to CXL memdevsVishal Verma
Add emulation for the 'Get FW Info', 'Transfer FW', and 'Activate FW' CXL mailbox commands to the cxl_test emulated memdevs to enable end-to-end unit testing of a firmware update flow. For now, only advertise an 'offline activation' capability as that is all the CXL memdev driver currently implements. Add some canned values for the serial number fields, and create a platform device sysfs knob to calculate the sha256sum of the firmware image that was received, so a unit test can compare it with the original file that was uploaded.

2023-06-25tools/testing/cxl: Use named effects for the Command Effect LogVishal Verma
As more emulated mailbox commands are added to cxl_test, it is a pain point to look up command effect numbers for each effect. Replace the bare numbers in the mock driver with an enum that lists all possible effects.

The CXL spec (3.0, section 8.2.9.8.4) Lists Inject Poison and Clear Poison as having the effects of "Immediate Data Change". Fix this in the mock driver so that the command effect log is populated correctly.
