I see you taken the brcmfmac fixes to stable, if I recall correctly the following commit was also pretty relevant and I don't think it was picked-up. It's in the upstream: commit 5cdb0ef6144f47440850553579aa923c20a63f23 Author: Piotr Figiel <p.figiel(a)camlintechnologies.com> Date: Mon Mar 4 15:42:52 2019 +0000 brcmfmac: fix NULL pointer derefence during USB disconnect Maybe you could consider also taking this. Best regards, -- Piotr Figiel

[PATCH 1/2] mm: Add readahead file operation

by Jan Kara

Some filesystems need to acquire locks before pages are read into page cache to protect from races with hole punching. The lock generally cannot be acquired within readpage as it ranks above page lock so we are left with acquiring the lock within filesystem's ->read_iter implementation for normal reads and ->fault implementation during page faults. That however does not cover all paths how pages can be instantiated within page cache - namely explicitely requested readahead. Add new ->readahead file operation which filesystem can use for this.

[PATCH v8 00/12] mm: Sub-section memory hotplug support

by Dan Williams

Changes since v7 [1]: - Make subsection helpers pfn based rather than physical-address based (Oscar and Pavel) - Make subsection bitmap definition scalable for different section and sub-section sizes across architectures. As a result: unsigned long map_active ...is converted to: DECLARE_BITMAP(subsection_map, SUBSECTIONS_PER_SECTION) ...and the helpers are renamed with a 'subsection' prefix. (Pavel) - New in this version is a touch of arch/powerpc/include/asm/sparsemem.h in "[PATCH v8 01/12] mm/sparsemem: Introduce struct mem_section_usage" to define ARCH_SUBSECTION_SHIFT. - Drop "mm/sparsemem: Introduce common definitions for the size and mask of a section" in favor of Robin's "mm/memremap: Rename and consolidate SECTION_SIZE" (Pavel) - Collect some more Reviewed-by tags. Patches that still lack review tags: 1, 3, 9 - 12 [1]: https://lore.kernel.org/lkml/155677652226.2336373.8700273400832001094.stgit… --- [merge logistics] Hi Andrew, These are too late for v5.2, I'm posting this v8 during the merge window to maintain the review momentum. --- [cover letter] The memory hotplug section is an arbitrary / convenient unit for memory hotplug. 'Section-size' units have bled into the user interface ('memblock' sysfs) and can not be changed without breaking existing userspace. The section-size constraint, while mostly benign for typical memory hotplug, has and continues to wreak havoc with 'device-memory' use cases, persistent memory (pmem) in particular. Recall that pmem uses devm_memremap_pages(), and subsequently arch_add_memory(), to allocate a 'struct page' memmap for pmem. However, it does not use the 'bottom half' of memory hotplug, i.e. never marks pmem pages online and never exposes the userspace memblock interface for pmem. This leaves an opening to redress the section-size constraint. To date, the libnvdimm subsystem has attempted to inject padding to satisfy the internal constraints of arch_add_memory(). Beyond complicating the code, leading to bugs [2], wasting memory, and limiting configuration flexibility, the padding hack is broken when the platform changes this physical memory alignment of pmem from one boot to the next. Device failure (intermittent or permanent) and physical reconfiguration are events that can cause the platform firmware to change the physical placement of pmem on a subsequent boot, and device failure is an everyday event in a data-center. It turns out that sections are only a hard requirement of the user-facing interface for memory hotplug and with a bit more infrastructure sub-section arch_add_memory() support can be added for kernel internal usages like devm_memremap_pages(). Here is an analysis of the current design assumptions in the current code and how they are addressed in the new implementation: Current design assumptions: - Sections that describe boot memory (early sections) are never unplugged / removed. - pfn_valid(), in the CONFIG_SPARSEMEM_VMEMMAP=y, case devolves to a valid_section() check - __add_pages() and helper routines assume all operations occur in PAGES_PER_SECTION units. - The memblock sysfs interface only comprehends full sections New design assumptions: - Sections are instrumented with a sub-section bitmask to track (on x86) individual 2MB sub-divisions of a 128MB section. - Partially populated early sections can be extended with additional sub-sections, and those sub-sections can be removed with arch_remove_memory(). With this in place we no longer lose usable memory capacity to padding. - pfn_valid() is updated to look deeper than valid_section() to also check the active-sub-section mask. This indication is in the same cacheline as the valid_section() so the performance impact is expected to be negligible. So far the lkp robot has not reported any regressions. - Outside of the core vmemmap population routines which are replaced, other helper routines like shrink_{zone,pgdat}_span() are updated to handle the smaller granularity. Core memory hotplug routines that deal with online memory are not touched. - The existing memblock sysfs user api guarantees / assumptions are not touched since this capability is limited to !online !memblock-sysfs-accessible sections. Meanwhile the issue reports continue to roll in from users that do not understand when and how the 128MB constraint will bite them. The current implementation relied on being able to support at least one misaligned namespace, but that immediately falls over on any moderately complex namespace creation attempt. Beyond the initial problem of 'System RAM' colliding with pmem, and the unsolvable problem of physical alignment changes, Linux is now being exposed to platforms that collide pmem ranges with other pmem ranges by default [3]. In short, devm_memremap_pages() has pushed the venerable section-size constraint past the breaking point, and the simplicity of section-aligned arch_add_memory() is no longer tenable. These patches are exposed to the kbuild robot on my libnvdimm-pending branch [4], and a preview of the unit test for this functionality is available on the 'subsection-pending' branch of ndctl [5].

[PATCH v2] mmc: dw_mmc: Disable SDIO interrupts while suspended to fix suspend/resume

by Douglas Anderson

Processing SDIO interrupts while dw_mmc is suspended (or partly suspended) seems like a bad idea. We really don't want to be processing them until we've gotten ourselves fully powered up. You might be wondering how it's even possible to become suspended when an SDIO interrupt is active. As can be seen in dw_mci_enable_sdio_irq(), we explicitly keep dw_mmc out of runtime suspend when the SDIO interrupt is enabled. ...but even though we stop normal runtime suspend transitions when SDIO interrupts are enabled, the dw_mci_runtime_suspend() can still get called for a full system suspend. Let's handle all this by explicitly masking SDIO interrupts in the suspend call and unmasking them later in the resume call. To do this cleanly I'll keep track of whether the client requested that SDIO interrupts be enabled so that we can reliably restore them regardless of whether we're masking them for one reason or another. It should be noted that if dw_mci_enable_sdio_irq() is never called (for instance, if we don't have an SDIO card plugged in) that "client_sdio_enb" will always be false. In those cases this patch adds a tiny bit of overhead to suspend/resume (a spinlock and a read/write of INTMASK) but other than that is a no-op. The SDMMC_INT_SDIO bit should always be clear and clearing it again won't hurt. Without this fix it can be seen that rk3288-veyron Chromebooks with Marvell WiFi would sometimes fail to resume WiFi even after picking my recent mwifiex patch [1]. Specifically you'd see messages like this: mwifiex_sdio mmc1:0001:1: Firmware wakeup failed mwifiex_sdio mmc1:0001:1: PREP_CMD: FW in reset state ...and tracing through the resume code in the failing cases showed that we were processing a SDIO interrupt really early in the resume call. NOTE: downstream in Chrome OS 3.14 and 3.18 kernels (both of which support the Marvell SDIO WiFi card) we had a patch ("CHROMIUM: sdio: Defer SDIO interrupt handling until after resume") [2]. Presumably this is the same problem that was solved by that patch. [1] https://lkml.kernel.org/r/20190404040106.40519-1-dianders@chromium.org [2] https://crrev.com/c/230765 Cc: <stable(a)vger.kernel.org> # 4.14.x Signed-off-by: Douglas Anderson <dianders(a)chromium.org> --- I didn't put any "Fixes" tag here, but presumably this could be backported to whichever kernels folks found it useful for. I have at least confirmed that kernels v4.14 and v4.19 (as well as v5.1-rc2) show the problem. It is very easy to pick this to v4.19 and it definitely fixes the problem there. I haven't spent the time to pick this to 4.14 myself, but presumably it wouldn't be too hard to backport this as far as v4.13 since that contains commit 32dba73772f8 ("mmc: dw_mmc: Convert to use MMC_CAP2_SDIO_IRQ_NOTHREAD for SDIO IRQs"). Prior to that it might make sense for anyone experiencing this problem to just pick the old CHROMIUM patch to fix them. Changes in v2: - Suggested 4.14+ in the stable tag (Sasha-bot) - Extra note that this is a noop on non-SDIO (Shawn / Emil) - Make boolean logic cleaner as per https://crrev.com/c/1586207/1 - Hopefully clear comments as per https://crrev.com/c/1586207/1 drivers/mmc/host/dw_mmc.c | 27 +++++++++++++++++++++++---- drivers/mmc/host/dw_mmc.h | 3 +++ 2 files changed, 26 insertions(+), 4 deletions(-) diff --git a/drivers/mmc/host/dw_mmc.c b/drivers/mmc/host/dw_mmc.c index 80dc2fd6576c..480067b87a94 100644 --- a/drivers/mmc/host/dw_mmc.c +++ b/drivers/mmc/host/dw_mmc.c @@ -1664,7 +1664,8 @@ static void dw_mci_init_card(struct mmc_host *mmc, struct mmc_card *card) } } -static void __dw_mci_enable_sdio_irq(struct dw_mci_slot *slot, int enb) +static void __dw_mci_enable_sdio_irq(struct dw_mci_slot *slot, bool enb, + bool client_requested) { struct dw_mci *host = slot->host; unsigned long irqflags; @@ -1672,6 +1673,20 @@ static void __dw_mci_enable_sdio_irq(struct dw_mci_slot *slot, int enb) spin_lock_irqsave(&host->irq_lock, irqflags); + /* + * If we're being called directly from dw_mci_enable_sdio_irq() + * (which means that the client driver actually wants to enable or + * disable interrupts) then save the request.
