MADV_FREE may split THPs if it is called for partial THP. It may trigger the below race: CPU A CPU B ----- ----- smaps walk: MADV_FREE: page_mapcount() PageCompound() split_huge_page() page = compound_head(page) PageDoubleMap(page) When calling PageDoubleMap() this page is not a tail page of THP anymore so the BUG is triggered. This could be fixed by elevated refcount of the page before calling mapcount, but it prevents from counting migration entries, and it seems overkilling because the race just could happen when PMD is split so all PTE entries of tail pages are actually migration entries, and smaps_account() does treat migration entries as mapcount == 1 as Kirill pointed out. Add a new parameter for smaps_account() to tell this entry is migration entry then skip calling page_mapcount(). Don't skip getting mapcount for device private entries since they do track references with mapcount. Pagemap also has the similar issue although it was not reported. Fixed it as well.

tcpci module in Kernel 5.15.74 with PTN5110 not working correctly

by Christian Bach

Hello For a few weeks now I am trying to make the PTN5110 chip work with the new Kernel 5.15.74. The same hardware setup was working with the 4.19.72 Kernel. The steps I took so far are as follows: 1. Study the Documentation and look at example Device Tree's in the Kernel 2. Try out different Device Tree configurations derived from the Documentation and examples 3. I did look on Stackoverflow, the NXP and other forums for any similar issue but could not find any 4. Updating the Kernel to the newest Version I was able to find: 5.15.74 (Hash: f0bee94053065c7cb8eacadfdd6bf739a2042b35 in Repo: git://git.yoctoproject.org/linux-yocto.git;branch=v5.15/standard/base) 5. Downgrade to the earliest Kernel possible: v5.10-rc1 (Hash: 3650b228f83adda7e5ee532e2b90429c03f7b9ec in Repo: git://git.yoctoproject.org/linux-yocto.git;branch=v5.15/standard/base) None of those steps had any effect. Every time I plug in a USB-A to USB-C cable the Kernel gets stuck in the ISR until I unplug the cable. (Attaching a full USB-PD capable Power Source over a USB-C cable works fine) This results in an unreasonable high CPU usage (most of the times the CPU gets blocked completely). I did analyze the I2C bus and found that the old Kernel did change many configurations after the A-C cable got attached while the new Kernel does nothing (please see logs below). I also did compare what happens on the I2C bus during chip initialization but did not find any mentionable differences.

[PATCH 0/6] hwpoison, shmem, hugetlb: fix data loss issue 5.10.y

by Mike Kravetz

This is a request for adding the following patches to stable 5.10.y. Poisoned shmem and hugetlb pages are removed from the pagecache. Subsequent access to the offset in the file results in a NEW zero filled page. Application code does not get notified of the data loss, and the only 'clue' is a message in the system log. Data loss has been experienced by real users. This was addressed upstream. Most commits were marked for backports, but some were not. This was discussed here [1] and here [2]. Patches apply cleanly to v5.4.224 and pass tests checking for this specific data loss issue. LTP mm tests show no regressions. All patches except 4 "mm: hwpoison: handle non-anonymous THP correctly" required a small bit of change to apply correctly: mostly for context. linux-mm Cc'ed as it would be great to get at least an ACK from others familiar with this issue.

When CONFIG_CPUMASK_OFFSTACK and CONFIG_DEBUG_PER_CPU_MAPS is selected, cpu_max_bits_warn() generates a runtime warning similar as below while we show /proc/cpuinfo.

[PATCH v2] KVM: x86: Do not return host topology information from KVM_GET_SUPPORTED_CPUID

by Paolo Bonzini

Passing the host topology to the guest is almost certainly wrong and will confuse the scheduler. In addition, several fields of these CPUID leaves vary on each processor; it is simply impossible to return the right values from KVM_GET_SUPPORTED_CPUID in such a way that they can be passed to KVM_SET_CPUID2. The values that will most likely prevent confusion are all zeroes. Userspace will have to override it anyway if it wishes to present a specific topology to the guest.

[PATCH v6 1/6] locking/rwsem: Prevent non-first waiter from spinning in down_write() slowpath

by Waiman Long

A non-first waiter can potentially spin in the for loop of rwsem_down_write_slowpath() without sleeping but fail to acquire the lock even if the rwsem is free if the following sequence happens: Non-first RT waiter First waiter Lock holder ------------------- ------------ ----------- Acquire wait_lock rwsem_try_write_lock(): Set handoff bit if RT or wait too long Set waiter->handoff_set Release wait_lock Acquire wait_lock Inherit waiter->handoff_set Release wait_lock Clear owner Release lock if (waiter.handoff_set) { rwsem_spin_on_owner((); if (OWNER_NULL) goto trylock_again; } trylock_again: Acquire wait_lock rwsem_try_write_lock(): if (first->handoff_set && (waiter != first)) return false; Release wait_lock A non-first waiter cannot really acquire the rwsem even if it mistakenly believes that it can spin on OWNER_NULL value. If that waiter happens to be an RT task running on the same CPU as the first waiter, it can block the first waiter from acquiring the rwsem leading to live lock. Fix this problem by making sure that a non-first waiter cannot spin in the slowpath loop without sleeping.

[PATCH 1/5] pwm: jz4740: Fix pin level of disabled TCU2 channels, part 1

by Paul Cercueil

The "duty > cycle" trick to force the pin level of a disabled TCU2 channel would only work when the channel had been enabled previously. Address this issue by enabling the PWM mode in jz4740_pwm_disable (I know, right) so that the "duty > cycle" trick works before disabling the PWM channel right after. This issue went unnoticed, as the PWM pins on the majority of the boards tested would default to the inactive level once the corresponding TCU clock was enabled, so the first call to jz4740_pwm_disable() would not actually change the pin levels. On the GCW Zero however, the PWM pin for the backlight (PWM1, which is a TCU2 channel) goes active as soon as the timer1 clock is enabled. Since the jz4740_pwm_disable() function did not work on channels not previously enabled, the backlight would shine at full brightness from the moment the backlight driver would probe, until the backlight driver tried to *enable* the PWM output. With this fix, the PWM pins will be forced inactive as soon as jz4740_pwm_apply() is called (and might be reconfigured to active if dictated by the pwm_state). This means that there is still a tiny time frame between the .request() and .apply() callbacks where the PWM pin might be active. Sadly, there is no way to fix this issue: it is impossible to write a PWM channel's registers if the corresponding clock is not enabled, and enabling the clock is what causes the PWM pin to go active. There is a workaround, though, which complements this fix: simply starting the backlight driver (or any PWM client driver) with a "init" pinctrl state that sets the pin as an inactive GPIO. Once the driver is probed and the pinctrl state switches to "default", the regular PWM pin configuration can be used as it will be properly driven.

[PATCH] usb: cdns3: remove fetched trb from cache before dequeuing

by Pawel Laszczak

After doorbell DMA fetches the TRB. If during dequeuing request driver changes NORMAL TRB to LINK TRB but doesn't delete it from controller cache then controller will handle cached TRB and packet can be lost. The example scenario for this issue looks like: 1. queue request - set doorbell 2. dequeue request 3. send OUT data packet from host 4. Device will accept this packet which is unexpected 5. queue new request - set doorbell 6. Device lost the expected packet. By setting DFLUSH controller clears DRDY bit and stop DMA transfer.
