2024-03-01vfio/pds: Always clear the save/restore FDs on resetBrett Creeley
After reset the VFIO device state will always be put in VFIO_DEVICE_STATE_RUNNING, but the save/restore files will only be cleared if the previous state was VFIO_DEVICE_STATE_ERROR. This can/will cause the restore/save files to be leaked if/when the migration state machine transitions through the states that re-allocates these files. Fix this by always clearing the restore/save files for resets.

For most nodes with a compatible property a platform device is created. For some an amba device is created instead. For the latter of_amba_device_create() emits a message at debug level about the node the device is created from. Add a similar message to of_platform_device_create_pdata() to inform about the whole list of created devices.

2024-03-01libfs: improve path_from_stashed()Christian Brauner
Right now we pass a bunch of info that is fs specific which doesn't make a lot of sense and it bleeds fs sepcific details into the generic helper. nsfs and pidfs have slightly different needs when initializing inodes. Add simple operations that are stashed in sb->s_fs_info that both can implement. This also allows us to get rid of cleaning up references in the caller. All in all path_from_stashed() becomes way simpler. Signed-off-by: Christian Brauner <brauner@kernel.org>

2024-03-01cpufreq: Don't unregister cpufreq cooling on CPU hotplugViresh Kumar
Offlining a CPU and bringing it back online is a common operation and it happens frequently during system suspend/resume, where the non-boot CPUs are hotplugged out during suspend and brought back at resume. The cpufreq core already tries to make this path as fast as possible as the changes are only temporary in nature and full cleanup of resources isn't required in this case. For example the drivers can implement online()/offline() callbacks to avoid a lot of tear down of resources. On similar lines, there is no need to unregister the cpufreq cooling device during suspend / resume, but only while the policy is getting removed. Moreover, unregistering the cpufreq cooling device is resulting in an unwanted outcome, where the system suspend is eventually aborted in the process. Currently, during system suspend the cpufreq core unregisters the cooling device, which in turn removes a kobject using device_del() and that generates a notification to the userspace via uevent broadcast. This causes system suspend to abort in some setups. This was also earlier reported (indirectly) by Roman [1]. Maybe there is another way around to fixing that problem properly, but this change makes sense anyways. Move the registering and unregistering of the cooling device to policy creation and removal times onlyy.

2024-03-01sched/idle: Conditionally handle tick broadcast in default_idle_call()Thomas Gleixner
The x86 architecture has an idle routine for AMD CPUs which are affected by erratum 400. On the affected CPUs the local APIC timer stops in the C1E halt state. It therefore requires tick broadcasting. The invocation of tick_broadcast_enter()/exit() from this function violates the RCU constraints because it can end up in lockdep or tracing, which rightfully triggers a warning. tick_broadcast_enter()/exit() must be invoked before ct_cpuidle_enter() and after ct_cpuidle_exit() in default_idle_call(). Add a static branch conditional invocation of tick_broadcast_enter()/exit() into this function to allow X86 to replace the AMD specific idle code. It's guarded by a config switch which will be selected by x86. Otherwise it's a NOOP.

2024-03-01x86/e820: Don't reserve SETUP_RNG_SEED in e820Jiri Bohac
SETUP_RNG_SEED in setup_data is supplied by kexec and should not be reserved in the e820 map. Doing so reserves 16 bytes of RAM when booting with kexec. (16 bytes because data->len is zeroed by parse_setup_data so only sizeof(setup_data) is reserved.) When kexec is used repeatedly, each boot adds two entries in the kexec-provided e820 map as the 16-byte range splits a larger range of usable memory. Eventually all of the 128 available entries get used up. The next split will result in losing usable memory as the new entries cannot be added to the e820 map.

2024-03-01ice: reorder disabling IRQ and NAPI in ice_qp_disMaciej Fijalkowski
ice_qp_dis() currently does things in very mixed way. Tx is stopped before disabling IRQ on related queue vector, then it takes care of disabling Rx and finally NAPI is disabled. Let us start with disabling IRQs in the first place followed by turning off NAPI. Then it is safe to handle queues. One subtle change on top of that is that even though ice_qp_ena() looks more sane, clear ICE_CFG_BUSY as the last thing there.

Currently routines that are supposed to toggle state of ring pair do not take care of associated interrupt with queue vector that these rings belong to. This causes funky issues such as dead interface due to irq misconfiguration, as per Pavel's report from Closes: tag.

For enable let's reuse ixgbe_irq_enable_queues(). Besides this, disable/enable NAPI as first/last thing when dealing with closing or opening ring pair that xsk_pool is being configured on.

2024-03-01ALSA: hwdep: Move put_user() call out of scoped_guard() in ↵Nathan Chancellor
snd_hwdep_control_ioctl() Clang prior to 17.0.0 has a bug in its asm goto jump scope analysis to determine that no variables with the cleanup attribute are skipped by an indirect jump. Instead of only checking the scope of each label that is a possible target of each asm goto statement, it checks the scope of every label, which can cause an error when a variable with the cleanup attribute is used between two asm goto statements with different scopes, even if they have completely different label targets: sound/core/hwdep.c:273:8: error: cannot jump from this asm goto statement to one of its possible targets if (get_user(device, (int __user *)arg)) ^ arch/powerpc/include/asm/uaccess.h:295:5: note: expanded from macro 'get_user' __get_user(x, _gu_addr) : \ ^ arch/powerpc/include/asm/uaccess.h:283:2: note: expanded from macro '__get_user' __get_user_size_allowed(__gu_val, __gu_addr, __gu_size, __gu_err); \ ^ arch/powerpc/include/asm/uaccess.h:199:3: note: expanded from macro '__get_user_size_allowed' __get_user_size_goto(x, ptr, size, __gus_failed); \ ^ arch/powerpc/include/asm/uaccess.h:187:10: note: expanded from macro '__get_user_size_goto' case 1: __get_user_asm_goto(x, (u8 __user *)ptr, label, "lbz"); break; \ ^ arch/powerpc/include/asm/uaccess.h:158:2: note: expanded from macro '__get_user_asm_goto' asm_volatile_goto( \ ^ include/linux/compiler_types.h:366:33: note: expanded from macro 'asm_volatile_goto' #define asm_volatile_goto(x...) asm goto(x) ^ sound/core/hwdep.c:291:9: note: possible target of asm goto statement if (put_user(device, (int __user *)arg)) ^ arch/powerpc/include/asm/uaccess.h:66:5: note: expanded from macro 'put_user' __put_user(x, _pu_addr) : -EFAULT; \ ^ arch/powerpc/include/asm/uaccess.h:52:9: note: expanded from macro '__put_user' \ ^ sound/core/hwdep.c:276:4: note: jump bypasses initialization of variable with __attribute__((cleanup)) scoped_guard(mutex, &register_mutex) { ^ include/linux/cleanup.h:169:20: note: expanded from macro 'scoped_guard' for (CLASS(_name, scope)(args), \ To avoid this issue, move the put_user() call out of the scoped_guard() scope, which allows the asm goto scope analysis to see that the variable with the cleanup attribute will never be skipped by the asm goto statements.

pktcdvd sets max_hw_sectors on the queue of the underlying device that it doesn't own (and doesn't reset it ever) since the driver was merged. This can create all kinds of problems as the underlying driver doesn't even know about it changing the limit. As the state purpose is to not create I/Os larger than a single frame, and pktcdvd never builds bios larger than that, just set REQ_NOMERGE on the bios it submits so that largers I/Os never get built.

2024-03-01RAS/AMD/FMPM: Add debugfs interface to print record entriesYazen Ghannam
It is helpful to see the saved record entries during run time in human-readable format. This is useful for testing during module development. It can also be used by system admins to quickly and easily see the state of the system. Provide a sequential file in debugfs to print fields of interest from the FRU records and their entries. Don't fail to load the module if the debugfs interface is not available. This is a convenience feature which does not affect other module functionality. The new interface reads the record entries and should hold the mutex. Expand the mutex code comment to clarify when it should be held.

2024-03-01RAS/AMD/FMPM: Save SPA valuesYazen Ghannam
The system physical address (SPA) of an error is not a stable value. It will change depending on the location of the memory: parts can be swapped. And it will change depending on memory topology: NUMA nodes and/or interleaving can be adjusted. Therefore, the SPA value is not part of the "FRU Memory Poison" record format. And it will not be saved to persistent storage. However, the SPA values can be helpful during debug and for system admins during run time. Save the SPA values in a separate structure. This is updated when records are restored and when new errors are saved.
