[PATCH v3 1/2] PCI: imx6: Correct the epc_features of IMX8MQ_EP

by Richard Zhu

IMX8MQ_EP has three 64-bit BAR0/2/4 capable and programmable BARs. For IMX8MQ_EP, use imx8q_pcie_epc_features (64-bit BARs 0, 2, 4) instead of imx8m_pcie_epc_features (64-bit BARs 0, 2).

[PATCH AUTOSEL 5.4 1/3] Revert "ACPI: battery: negate current when discharging"

by Sasha Levin

From: "Rafael J. Wysocki" <rafael.j.wysocki(a)intel.com> [ Upstream commit de1675de39aa945bad5937d1fde4df3682670639 ] Revert commit 234f71555019 ("ACPI: battery: negate current when discharging") breaks not one but several userspace implementations of battery monitoring: Steam and MangoHud. Perhaps it breaks more, but those are the two that have been tested. Reported-by: Matthew Schwartz <matthew.schwartz(a)linux.dev> Closes: https://lore.kernel.org/linux-acpi/87C1B2AF-D430-4568-B620-14B941A8ABA4@lin… Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki(a)intel.com> Signed-off-by: Sasha Levin <sashal(a)kernel.org> --- **YES**, this commit should be backported to stable kernel trees. ## Extensive Explanation: ### 1. **Critical Userspace Regression Fix** This revert fixes a critical regression that breaks userspace applications. The commit message explicitly states that the original change "breaks not one but several userspace implementations of battery monitoring: Steam and MangoHud." This is a clear violation of the kernel's "no userspace regressions" rule, which is one of the most fundamental principles in kernel development. ### 2. **Code Analysis Shows ABI Change** Looking at the code changes: ```c // The problematic code that was added (and is now being removed): if (psp == POWER_SUPPLY_PROP_CURRENT_NOW && (battery->state & ACPI_BATTERY_STATE_DISCHARGING) && acpi_battery_handle_discharging(battery) == POWER_SUPPLY_STATUS_DISCHARGING) val->intval = -val->intval; ``` This code was changing the sign of the current value when discharging, which altered the userspace-visible ABI. Even if the original behavior didn't match documentation, changing it broke existing applications that depended on the long-standing behavior. ### 3. **Simple and Safe Revert** The commit is a clean revert that: - Removes the problematic sign negation logic - Restores the original behavior that userspace applications expect - Is self-contained to the `acpi_battery_get_property()` function - Has minimal risk of introducing new issues ### 4. **Meets Stable Kernel Criteria** According to stable kernel rules, this commit qualifies because it: - **Fixes a real bug** that users are hitting (broken battery monitoring in Steam and MangoHud) - **Is obviously correct** (it's a revert of a change that broke userspace) - **Is small and contained** (only affects the ACPI battery property reporting) - **Has been tested** (the reporter confirmed the issue) - **Fixes a regression** (restores previous working behavior) ### 5. **Comparison to Similar Commits** Looking at the historical commits marked with "Backport Status: YES", they share similar characteristics: - Fix actual problems affecting users - Are relatively small and contained changes - Don't introduce new features or architectural changes - Focus on fixing specific issues This revert fits perfectly into this pattern as it's fixing a specific userspace compatibility issue without introducing any new functionality. ### 6. **Timing Considerations** The original problematic commit (234f71555019) was from May 8, 2025, and this revert is from July 3, 2025. If the original commit made it into any stable releases, those stable trees would need this revert to prevent userspace breakage. ### Conclusion: This is a textbook example of a commit that should be backported to stable kernels. It fixes a userspace regression, is minimal in scope, carries very low risk, and restores previously working behavior that applications depend on. The fact that it's a revert of a problematic change makes it even more suitable for stable backporting. drivers/acpi/battery.c | 19 +++---------------- 1 file changed, 3 insertions(+), 16 deletions(-) diff --git a/drivers/acpi/battery.c b/drivers/acpi/battery.c index a5e120eca7f33..cf853e985d6d9 100644 --- a/drivers/acpi/battery.c +++ b/drivers/acpi/battery.c @@ -266,23 +266,10 @@ static int acpi_battery_get_property(struct power_supply *psy, break; case POWER_SUPPLY_PROP_CURRENT_NOW: case POWER_SUPPLY_PROP_POWER_NOW: - if (battery->rate_now == ACPI_BATTERY_VALUE_UNKNOWN) { + if (battery->rate_now == ACPI_BATTERY_VALUE_UNKNOWN) ret = -ENODEV; - break; - } - - val->intval = battery->rate_now * 1000; - /* - * When discharging, the current should be reported as a - * negative number as per the power supply class interface - * definition. - */ - if (psp == POWER_SUPPLY_PROP_CURRENT_NOW && - (battery->state & ACPI_BATTERY_STATE_DISCHARGING) && - acpi_battery_handle_discharging(battery) - == POWER_SUPPLY_STATUS_DISCHARGING) - val->intval = -val->intval; - + else + val->intval = battery->rate_now * 1000; break; case POWER_SUPPLY_PROP_CHARGE_FULL_DESIGN: case POWER_SUPPLY_PROP_ENERGY_FULL_DESIGN: -- 2.39.5

Wysocki <rafael.j.wysocki(a)intel.com> Signed-off-by: Sasha Levin <sashal(a)kernel.org> --- **YES**, this commit should be backported to stable kernel trees. ## Extensive Explanation: ### 1. **Critical Userspace Regression Fix** This revert fixes a critical regression that breaks userspace applications. The commit message explicitly states that the original change "breaks not one but several userspace implementations of battery monitoring: Steam and MangoHud." This is a clear violation of the kernel's "no userspace regressions" rule, which is one of the most fundamental principles in kernel development. ### 2. **Code Analysis Shows ABI Change** Looking at the code changes: ```c // The problematic code that was added (and is now being removed): if (psp == POWER_SUPPLY_PROP_CURRENT_NOW && (battery->state & ACPI_BATTERY_STATE_DISCHARGING) && acpi_battery_handle_discharging(battery) == POWER_SUPPLY_STATUS_DISCHARGING) val->intval = -val->intval; ``` This code was changing the sign of the current value when discharging, which altered the userspace-visible ABI. Even if the original behavior didn't match documentation, changing it broke existing applications that depended on the long-standing behavior. ### 3. **Simple and Safe Revert** The commit is a clean revert that: - Removes the problematic sign negation logic - Restores the original behavior that userspace applications expect - Is self-contained to the `acpi_battery_get_property()` function - Has minimal risk of introducing new issues ### 4. **Meets Stable Kernel Criteria** According to stable kernel rules, this commit qualifies because it: - **Fixes a real bug** that users are hitting (broken battery monitoring in Steam and MangoHud) - **Is obviously correct** (it's a revert of a change that broke userspace) - **Is small and contained** (only affects the ACPI battery property reporting) - **Has been tested** (the reporter confirmed the issue) - **Fixes a regression** (restores previous working behavior) ### 5. **Comparison to Similar Commits** Looking at the historical commits marked with "Backport Status: YES", they share similar characteristics: - Fix actual problems affecting users - Are relatively small and contained changes - Don't introduce new features or architectural changes - Focus on fixing specific issues This revert fits perfectly into this pattern as it's fixing a specific userspace compatibility issue without introducing any new functionality. ### 6. **Timing Considerations** The original problematic commit (234f71555019) was from May 8, 2025, and this revert is from July 3, 2025. If the original commit made it into any stable releases, those stable trees would need this revert to prevent userspace breakage. ### Conclusion: This is a textbook example of a commit that should be backported to stable kernels. It fixes a userspace regression, is minimal in scope, carries very low risk, and restores previously working behavior that applications depend on. The fact that it's a revert of a problematic change makes it even more suitable for stable backporting. drivers/acpi/battery.c | 19 +++---------------- 1 file changed, 3 insertions(+), 16 deletions(-) diff --git a/drivers/acpi/battery.c b/drivers/acpi/battery.c index b0a5d077db905..8bb0f4d06adc0 100644 --- a/drivers/acpi/battery.c +++ b/drivers/acpi/battery.c @@ -250,23 +250,10 @@ static int acpi_battery_get_property(struct power_supply *psy, break; case POWER_SUPPLY_PROP_CURRENT_NOW: case POWER_SUPPLY_PROP_POWER_NOW: - if (battery->rate_now == ACPI_BATTERY_VALUE_UNKNOWN) { + if (battery->rate_now == ACPI_BATTERY_VALUE_UNKNOWN) ret = -ENODEV; - break; - } - - val->intval = battery->rate_now * 1000; - /* - * When discharging, the current should be reported as a - * negative number as per the power supply class interface - * definition. - */ - if (psp == POWER_SUPPLY_PROP_CURRENT_NOW && - (battery->state & ACPI_BATTERY_STATE_DISCHARGING) && - acpi_battery_handle_discharging(battery) - == POWER_SUPPLY_STATUS_DISCHARGING) - val->intval = -val->intval; - + else + val->intval = battery->rate_now * 1000; break; case POWER_SUPPLY_PROP_CHARGE_FULL_DESIGN: case POWER_SUPPLY_PROP_ENERGY_FULL_DESIGN: -- 2.39.5

+ mm-check-if-folio-has-valid-mapcount-before-folio_test_anonksm-when-necessary.patch added to mm-new branch

by Andrew Morton

The patch titled Subject: mm: check if folio has valid mapcount before folio_test_{anon,ksm}() when necessary has been added to the -mm mm-new branch. Its filename is mm-check-if-folio-has-valid-mapcount-before-folio_test_anonksm-when-necessary.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patche… This patch will later appear in the mm-new branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Note, mm-new is a provisional staging ground for work-in-progress patches, and acceptance into mm-new is a notification for others take notice and to finish up reviews. Please do not hesitate to respond to review feedback and post updated versions to replace or incrementally fixup patches in mm-new. Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Harry Yoo <harry.yoo(a)oracle.com> Subject: mm: check if folio has valid mapcount before folio_test_{anon,ksm}() when necessary Date: Mon, 7 Jul 2025 21:07:40 +0900 folio_test_anon() and folio_test_ksm() may return false positives when the folio is a typed page (except hugetlb), because lower bits of folio->mapping field can be set even if it doesn't mean FOLIO_MAPPING_* flags. To avoid false positives, folio_test_{anon,ksm}() should be called only if !page_has_type(&folio->page) || folio_test_hugetlb(folio). However, the check can be skipped if a folio is or will be mapped to userspace because typed pages that are not hugetlb folios cannot be mapped to userspace. As folio_expected_ref_count() already does the check, introduce a helper function folio_has_mapcount() and use it in folio_expected_ref_count() and stable_page_flags(). Update the comment in FOLIO_MAPPING_* flags accordingly.

The amd64_edac module logs DIMM sizes on a per-UMC per-CS granularity during init using these two registers. Currently, the module primarily considers only the Address Mask register for computing DIMM sizes. The Secondary Address Mask register is only considered for odd CS. Additionally, if it has been considered, the Address Mask register is ignored altogether for that CS. For power-of-two DIMMs i.e. DIMMs whose total capacity is a power of two (32GB, 64GB, etc), this is not an issue since only the Address Mask register is used. For non-power-of-two DIMMs i.e., DIMMs whose total capacity is not a power of two (48GB, 96GB, etc), however, the Secondary Address Mask register is used in conjunction with the Address Mask register. However, since the module only considers either of the two registers for a CS, the size computed by the module is incorrect. The Secondary Address Mask register is not considered for even CS, and the Address Mask register is not considered for odd CS. Introduce a new helper function so that both Address Mask and Secondary Address Mask registers are considered, when valid, for computing DIMM sizes. Furthermore, also rename some variables for greater clarity.

[PATCH 2/2] platform/x86: ideapad-laptop: Fix kbd backlight not remembered among boots

by Rong Zhang

On some models supported by ideapad-laptop, the HW/FW can remember the state of keyboard backlight among boots. However, it is always turned off while shutting down, as a side effect of the LED class device unregistering sequence. This is inconvenient for users who always prefer turning on the keyboard backlight. Thus, set LED_RETAIN_AT_SHUTDOWN on the LED class device so that the state of keyboard backlight gets remembered, which also aligns with the behavior of manufacturer utilities on Windows.

[PATCH 1/2] platform/x86: ideapad-laptop: Fix FnLock not remembered among boots

by Rong Zhang

On devices supported by ideapad-laptop, the HW/FW can remember the FnLock state among boots. However, since the introduction of the FnLock LED class device, it is turned off while shutting down, as a side effect of the LED class device unregistering sequence. Many users always turn on FnLock because they use function keys much more frequently than multimedia keys. The behavior change is inconvenient for them. Thus, set LED_RETAIN_AT_SHUTDOWN on the LED class device so that the FnLock state gets remembered, which also aligns with the behavior of manufacturer utilities on Windows.
