[PATCH] pinctrl: nuvoton: Fix boot on ma35dx platforms

by Miquel Raynal

As part of a wider cleanup trying to get rid of OF specific APIs, an incorrect (and partially unrelated) cleanup was introduced. The goal was to replace a device_for_each_chil_node() loop including an additional condition inside by a macro doing both the loop and the check on a single line. The snippet: device_for_each_child_node(dev, child) if (fwnode_property_present(child, "gpio-controller")) continue; was replaced by: for_each_gpiochip_node(dev, child) which expands into: device_for_each_child_node(dev, child) for_each_if(fwnode_property_present(child, "gpio-controller")) This change is actually doing the opposite of what was initially expected, breaking the probe of this driver, breaking at the same time the whole boot of Nuvoton platforms (no more console, the kernel WARN()). Revert these two changes to roll back to the correct behavior.

[PATCH v2] pinctrl: qcom: msm: mark certain pins as invalid for interrupts

by Bartosz Golaszewski

From: Bartosz Golaszewski <bartosz.golaszewski(a)linaro.org> On some platforms, the UFS-reset pin has no interrupt logic in TLMM but is nevertheless registered as a GPIO in the kernel. This enables the user-space to trigger a BUG() in the pinctrl-msm driver by running, for example: `gpiomon -c 0 113` on RB2. The exact culprit is requesting pins whose intr_detection_width setting is not 1 or 2 for interrupts. This hits a BUG() in msm_gpio_irq_set_type(). Potentially crashing the kernel due to an invalid request from user-space is not optimal, so let's go through the pins and mark those that would fail the check as invalid for the irq chip as we should not even register them as available irqs. This function can be extended if we determine that there are more corner-cases like this.

[PATCH v2 1/3] mtd: spinand: winbond: Fix W35N number of planes/LUN

by Miquel Raynal

There's been a mistake when extracting the geometry of the W35N02 and W35N04 chips from the datasheet. There is a single plane, however there are respectively 2 and 4 LUNs. They are actually referred in the datasheet as dies (equivalent of target), but as there is no die select operation and the chips only feature a single configuration register for the entire chip (instead of one per die), we can reasonably assume we are talking about LUNs and not dies.

[PATCH 1/4] mm/shmem, swap: improve cached mTHP handling and fix potential hung

by Kairui Song

From: Kairui Song <kasong(a)tencent.com> The current swap-in code assumes that, when a swap entry in shmem mapping is order 0, its cached folios (if present) must be order 0 too, which turns out not always correct. The problem is shmem_split_large_entry is called before verifying the folio will eventually be swapped in, one possible race is: CPU1 CPU2 shmem_swapin_folio /* swap in of order > 0 swap entry S1 */ folio = swap_cache_get_folio /* folio = NULL */ order = xa_get_order /* order > 0 */ folio = shmem_swap_alloc_folio /* mTHP alloc failure, folio = NULL */ <... Interrupted ...> shmem_swapin_folio /* S1 is swapped in */ shmem_writeout /* S1 is swapped out, folio cached */ shmem_split_large_entry(..., S1) /* S1 is split, but the folio covering it has order > 0 now */ Now any following swapin of S1 will hang: `xa_get_order` returns 0, and folio lookup will return a folio with order > 0. The `xa_get_order(&mapping->i_pages, index) != folio_order(folio)` will always return false causing swap-in to return -EEXIST. And this looks fragile. So fix this up by allowing seeing a larger folio in swap cache, and check the whole shmem mapping range covered by the swapin have the right swap value upon inserting the folio. And drop the redundant tree walks before the insertion. This will actually improve the performance, as it avoided two redundant Xarray tree walks in the hot path, and the only side effect is that in the failure path, shmem may redundantly reallocate a few folios causing temporary slight memory pressure. And worth noting, it may seems the order and value check before inserting might help reducing the lock contention, which is not true. The swap cache layer ensures raced swapin will either see a swap cache folio or failed to do a swapin (we have SWAP_HAS_CACHE bit even if swap cache is bypassed), so holding the folio lock and checking the folio flag is already good enough for avoiding the lock contention. The chance that a folio passes the swap entry value check but the shmem mapping slot has changed should be very low.
