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.

net: WQ_PERCPU added to alloc_workqueue users

2025-09-23T00:40:30Z

Currently if a user enqueue a work item using schedule_delayed_work() the used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to schedule_work() that is using system_wq and queue_work(), that makes use again of WORK_CPU_UNBOUND. This lack of consistentcy cannot be addressed without refactoring the API. alloc_workqueue() treats all queues as per-CPU by default, while unbound workqueues must opt-in via WQ_UNBOUND. This default is suboptimal: most workloads benefit from unbound queues, allowing the scheduler to place worker threads where they’re needed and reducing noise when CPUs are isolated. This change adds a new WQ_PERCPU flag at the network subsystem, to explicitly request the use of the per-CPU behavior. Both flags coexist for one release cycle to allow callers to transition their calls. Once migration is complete, WQ_UNBOUND can be removed and unbound will become the implicit default. With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND), any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND must now use WQ_PERCPU. All existing users have been updated accordingly.

net: intel: fm10k: Fix parameter idx set but not used

2025-09-19T15:42:08Z

Variable idx is set in the loop, but is never used resulting in dead code. Building with GCC 16, which enables -Werror=unused-but-set-parameter= by default results in build error. This patch removes the idx parameter, since all the callers of the fm10k_unbind_hw_stats_q as 0 as idx anyways.

eth: intel: use vmalloc_array() to simplify code

2025-08-19T00:49:51Z

Remove array_size() calls and replace vmalloc() with vmalloc_array() to simplify the code and maintain consistency with existing kmalloc_array() usage. vmalloc_array() is also optimized better, resulting in less instructions being used.

ethernet: intel: fix building with large NR_CPUS

2025-07-15T20:01:15Z

With large values of CONFIG_NR_CPUS, three Intel ethernet drivers fail to compile like: In function ‘i40e_free_q_vector’, inlined from ‘i40e_vsi_alloc_q_vectors’ at drivers/net/ethernet/intel/i40e/i40e_main.c:12112:3: 571 | _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__) include/linux/rcupdate.h:1084:17: note: in expansion of macro ‘BUILD_BUG_ON’ 1084 | BUILD_BUG_ON(offsetof(typeof(*(ptr)), rhf) >= 4096); \ drivers/net/ethernet/intel/i40e/i40e_main.c:5113:9: note: in expansion of macro ‘kfree_rcu’ 5113 | kfree_rcu(q_vector, rcu); | ^~~~~~~~~ The problem is that the 'rcu' member in 'q_vector' is too far from the start of the structure.
