[ Upstream commit 6f05d076 ] The support for dynamic ftrace with CONFIG_DEBUG_RODATA involves overriding the weak arch_ftrace_update_code() with a variant which makes the kernel text writable around the patching. This override was however added under the CONFIG_OLD_MCOUNT ifdef, and CONFIG_OLD_MCOUNT is only enabled if frame pointers are enabled. This leads to non-functional dynamic ftrace (ftrace triggers a WARN_ON()) when CONFIG_DEBUG_RODATA is enabled and CONFIG_FRAME_POINTER is not. Move the override out of that ifdef and into the CONFIG_DYNAMIC_FTRACE ifdef where it belongs. Fixes: 80d6b0c2 ("ARM: mm: allow text and rodata sections to be read-only") Suggested-by:

[ Upstream commit fba4f472 ] A CPU in VMX root mode will ignore INIT signals and will fail to bring up the APs after reboot. Therefore, on a panic we disable VMX on all CPUs before rebooting or triggering kdump. Do this when halting the machine as well, in case a firmware-level reboot does not perform a cold reset for all processors. Without doing this, rebooting the host may hang. Signed-off-by:

[ Upstream commit fb9e67be ] 'chan_stats' is (re)allocated in _mwifiex_fw_dpc() -> mwifiex_init_channel_scan_gap(), which is called whenever the device is initialized -- at probe or at reset. But we only free it in we completely unregister the adapter, meaning we leak a copy of it during every reset. Let's free it in the shutdown / removal paths instead (and in the error-handling path), to avoid the leak. Ideally, we can eventually unify much of mwifiex_shutdown_sw() and mwifiex_remove_card() (way too much copy-and-paste) to reduce the burden on bugfixes like this. But that's work for tomorrow.

[ Upstream commit bd9166ff ] At the moment kvmppc_mmu_map_page() returns -1 if mmu_hash_ops.hpte_insert() fails for any reason so the page fault handler resumes the guest and it faults on the same address again. This adds distinction to kvmppc_mmu_map_page() to return -EIO if mmu_hash_ops.hpte_insert() failed for a reason other than full pteg. At the moment only pSeries_lpar_hpte_insert() returns -2 if plpar_pte_enter() failed with a code other than H_PTEG_FULL. Other mmu_hash_ops.hpte_insert() instances can only fail with -1 "full pteg". With this change, if PR KVM fails to update HPT, it can signal the userspace about this instead of returning to guest and having the very same page fault over and over again. Signed-off-by:

[ Upstream commit 25d1d50e ] Passed through SCSI targets may have transfer limits which come from the host SCSI controller or something on the host side other than the target itself. To make this work properly, the hypervisor can adjust the target's VPD information to advertise these limits. But for that to work, the guest has to look at the VPD pages, which we won't do by default if it is an SPC-2 device, even if it does actually support it. This adds a workaround to address this, forcing devices attached to a virtio-scsi controller to always check the VPD pages. This is modelled on a similar workaround for the storvsc (Hyper-V) SCSI controller, although that exists for slightly different reasons. A specific case which causes this is a volume from IBM's IPR RAID controller (which presents as an SPC-2 device, although it does support VPD) passed through with qemu's 'scsi-block' device.

[ Upstream commit 2220fb29 ] The notification infrastructure (iwl_notification_wait_* functions) allows to wait until a list of notifications will come up from the firmware and to run a special handler (notif_wait handler) when those are received. The operation mode notifies the notification infrastructure about any Rx being received by the mean of iwl_notification_wait_notify() which will do two things: 1) call the notif_wait handler 2) wakeup the thread that was waiting for the notification Typically, only after those two steps happened, the operation mode will run its own handler for the notification that was received from the firmware. This means that the thread that was waiting for that notification can be running before the operation mode's handler was called. When the operation mode's handler is ASYNC, things get even worse since the thread that was waiting for the notification isn't even guaranteed that the ASYNC callback was added to async_handlers_list before it starts to run. This means that even calling iwl_mvm_wait_for_async_handlers() can't guarantee that absolutely everything related to that notification has run. The following can happen: Thread sending the command Operation mode's Rx path -------------------------- ------------------------ iwl_init_notification_wait() iwl_mvm_send_cmd() iwl_mvm_rx_common() iwl_notification_wait_notify() iwl_mvm_wait_for_async_handlers() // Possibly free some data // structure list_add_tail(async_handlers_list); schedule_work(async_handlers_wk); // Access the freed structure Split the 'run notif_wait's handler' and the 'wake up the thread' parts to fix this. This allows the operation mode to do the following: Thread sending the command Operation mode's Rx path -------------------------- ------------------------ iwl_init_notification_wait() iwl_mvm_send_cmd() iwl_mvm_rx_common() iwl_notification_wait() // Will run the notif_wait's handler list_add_tail(async_handlers_list); schedule_work(async_handlers_wk); iwl_notification_notify() iwl_mvm_wait_for_async_handlers() This way, the waiter is guaranteed that all the handlers have been run (if SYNC), or at least enqueued (if ASYNC) by the time it wakes up.

[ Upstream commit c0c345d4 ] As per latest regulatory update for India, channel 52, 56, 60, 64 is no longer restricted to DFS. Enabling DFS/no infra flags in driver results in applying all DFS related restrictions (like doing CAC etc before this channel moves to 'available state') for these channels even though the country code is programmed as 'India' in he hardware, fix this by relaxing the frequency range while applying RADAR flags only if the country code is programmed to India. If the frequency range needs to modified based on different country code, ath_is_radar_freq can be extended/modified dynamically. Signed-off-by:

[ Upstream commit e7080d44 ] It started with a sporadic message in syslog: "CAM tried to send a buffer larger than the ecount size" This message is not the fault itself, but a consecutive fault, after a read error from the CAM. This happens only on several CAMs, several hardware, and of course sporadic. It is a consecutive fault, if the last read from the CAM did fail. I guess this will not happen on all CAMs, but at least it did on mine. There was a write error to the CAM and during the re-initialization procedure, the CAM finished the last read, although it got a RS. The write error to the CAM happened because a race condition between HC write, checking DA and FR. This patch added an additional check for DA(RE), just after checking FR. It is important to read the CAMs status register again, to give the CAM the necessary time for a proper reaction to HC. Please note the description within the source code (patch below).

[ Upstream commit e058e7a4 ] Description of the problem: - i2c-scmi driver contains only two identifiers "SMBUS01" and "SMBUSIBM"; - the fist HID (SMBUS01) is clearly defined in "SMBus Control Method Interface Specification, version 1.0": "Each device must specify 'SMBUS01' as its _HID and use a unique _UID value"; - unfortunately, BIOS vendors (like AMI) seem to ignore this requirement and implement "SMB0001" HID instead of "SMBUS01"; - I speculate that they do this because only "SMB0001" is hard coded in Windows SMBus driver produced by Microsoft. This leads to following situation: - SMBus works out of box in Windows but not in Linux; - board vendors are forced to add correct "SMBUS01" HID to BIOS to make SMBus work in Linux. Moreover the same board vendors complain that tools (3-rd party ASL compiler) do not like the "SMBUS01" identifier and produce errors. So they need to constantly patch the compiler for each new version of BIOS. As it is very unlikely that BIOS vendors implement a correct HID in future, I would propose to consider whether it is possible to work around the problem by adding MS HID to the Linux i2c-scmi driver. v2: move the definition of the new HID to the driver itself.

[ Upstream commit 382bd4de ] When requesting a shared irq with IRQF_TRIGGER_NONE then the irqaction flags get filled with the trigger type from the irq_data: if (!(new->flags & IRQF_TRIGGER_MASK)) new->flags |= irqd_get_trigger_type(&desc->irq_data); On the first setup_irq() the trigger type in irq_data is NONE when the above code executes, then the irq is started up for the first time and then the actual trigger type gets established, but that's too late to fix up new->flags. When then a second user of the irq requests the irq with IRQF_TRIGGER_NONE its irqaction's triggertype gets set to the actual trigger type and the following check fails: if (!((old->flags ^ new->flags) & IRQF_TRIGGER_MASK)) Resulting in the request_irq failing with -EBUSY even though both users requested the irq with IRQF_SHARED | IRQF_TRIGGER_NONE Fix this by comparing the new irqaction's trigger type to the trigger type stored in the irq_data which correctly reflects the actual trigger type being used for the irq.

This is achieved by temporarily setting the affinity of the calling user space thread to the requested CPU and reset it to the original affinity afterwards. That's racy vs. CPU hotplug and concurrent affinity settings for that thread resulting in code executing on the wrong CPU and overwriting the new affinity setting. acpi_processor_get_throttling() is invoked in two ways: 1) The CPU online callback, which is already running on the target CPU and obviously protected against hotplug and not affected by affinity settings. 2) The ACPI driver probe function, which is not protected against hotplug during modprobe. Switch it over to work_on_cpu() and protect the probe function against CPU hotplug. Signed-off-by:

[ Upstream commit 7ee06cb2 ] The classic PC rtc-coms driver has a workaround for broken ACPI device nodes for it which lack an irq resource. This workaround used to unconditionally hardcode the irq to 8 in these cases. This was causing irq conflict problems on systems without a legacy-pic so a recent patch added an if (nr_legacy_irqs()) guard to the workaround to avoid this irq conflict. nr_legacy_irqs() uses the legacy_pic symbol under the hood causing an undefined symbol error if the rtc-cmos code is build as a module.

commit 3be23274 upstream. Discrete TPMs are often connected over slow serial buses which, on some platforms, can have glitches causing bit flips. If a bit does flip it could cause an overrun if it's in one of the size parameters, so sanity check that we're not overrunning the provided buffer when doing a memcpy(). Signed-off-by:

commit c8e4e5bd upstream. Corrected the register to check the 64-bit pointer capability state. 64-bit pointer implementation capability was checking in wrong register, which causes the BDC enumeration failure in 64-bit memory address. Fixes: efed421a ("usb: gadget: Add UDC driver for Broadcom USB3.0 device controller IP BDC") Reviewed-by:
