treewide: Drop pci_save_state() after pci_restore_state()

2026-02-11T12:41:45Z

commit 383d89699c5028de510a6667f674ed38585f77fc upstream. In 2009, commit c82f63e411f1 ("PCI: check saved state before restore") changed the behavior of pci_restore_state() such that it became necessary to call pci_save_state() afterwards, lest recovery from subsequent PCI errors fails. The commit has just been reverted and so all the pci_save_state() after pci_restore_state() calls that have accumulated in the tree are now superfluous. Drop them. Two drivers chose a different approach to achieve the same result: drivers/scsi/ipr.c and drivers/net/ethernet/intel/e1000e/netdev.c set the pci_dev's "state_saved" flag to true before calling pci_restore_state(). Drop this as well.

tg3: prevent use of uninitialized remote_adv and local_adv variables

2025-10-16T00:16:49Z

Some execution paths that jump to the fiber_setup_done label could leave the remote_adv and local_adv variables uninitialized and then use it. Initialize this variables at the point of definition to avoid this.

tg3: Disable tg3 PCIe AER on system reboot

2025-02-03T10:12:14Z

Disable PCIe AER on the tg3 device on system reboot on a limited list of Dell PowerEdge systems. This prevents a fatal PCIe AER event on the tg3 device during the ACPI _PTS (prepare to sleep) method for S5 on those systems. The _PTS is invoked by acpi_enter_sleep_state_prep() as part of the kernel's reboot sequence as a result of commit 38f34dba806a ("PM: ACPI: reboot: Reinstate S5 for reboot"). There was an earlier fix for this problem by commit 2ca1c94ce0b6 ("tg3: Disable tg3 device on system reboot to avoid triggering AER"). But it was discovered that this earlier fix caused a reboot hang when some Dell PowerEdge servers were booted via ipxe. To address this reboot hang, the earlier fix was essentially reverted by commit 9fc3bc764334 ("tg3: power down device only on SYSTEM_POWER_OFF"). This re-exposed the tg3 PCIe AER on reboot problem. This fix is not an ideal solution because the root cause of the AER is in system firmware. Instead, it's a targeted work-around in the tg3 driver. Note also that the PCIe AER must be disabled on the tg3 device even if the system is configured to use "firmware first" error handling.

eth: tg3: fix calling napi_enable() in atomic context

2025-01-27T22:30:49Z

tg3 has a spin lock protecting most of the config, switch to taking netdev_lock() explicitly on enable/start paths. Disable/stop paths seem to not be under the spin lock (since napi_disable() already needs to sleep), so leave that side as is. tg3_restart_hw() releases and re-takes the spin lock, we need to do the same because dev_close() needs to take netdev_lock().
