git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm由 Linus Torvalds 提交于
Pull libnvdimm fixes from Dan Williams: - Fix for the nd_blk (NVDIMM Block Window Aperture) driver. A spec clarification requires the driver to mask off reserved bits in status register. This is tagged for -stable back to the v4.2 kernel. - Fix for a kernel crash in the nvdimm unit tests when module loading is interrupted with SIGTERM. Tagged for -stable since validation efforts external to Intel use the unit tests for qualifying backports. - Add a new 'size' sysfs attribute for the BTT (NVDIMM Block Translation Table) driver to make it symmetric with the other namespace personality drivers (PFN and DAX) that provide a size attribute for indicating how much namespace capacity is lost to metadata. The BTT change arrived at the start of the merge window and has appeared in a -next release. It can technically wait for 4.9, but it is small, fixes asymmetry in the libnvdimm-sysfs interface, and something I would have squeezed into the v4.8 pull request had it arrived a few days earlier. * 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: tools/testing/nvdimm: fix SIGTERM vs hotplug crash nvdimm, btt: add a size attribute for BTTs libnvdimm, nd_blk: mask off reserved status bits

An offline memory cgroup might have anonymous memory or shmem left charged to it and no swap. Since only swap entries pin the id of an offline cgroup, such a cgroup will have no id and so an attempt to swapout its anon/shmem will not store memory cgroup info in the swap cgroup map. As a result, memcg->swap or memcg->memsw will never get uncharged from it and any of its ascendants. Fix this by always charging swapout to the first ancestor cgroup that hasn't released its id yet.

When memory hotplug operates, free hugepages will be freed if the movable node is offline. Therefore, /proc/sys/vm/nr_hugepages will be incorrect. Fix it by reducing max_huge_pages when the node is offlined. n-horiguchi@ah.jp.nec.com said: : dissolve_free_huge_page intends to break a hugepage into buddy, and the : destination hugepage is supposed to be allocated from the pool of the : destination node, so the system-wide pool size is reduced. So adding : h->max_huge_pages-- makes sense to me.

In page_remove_file_rmap(.) we have the following check: VM_BUG_ON_PAGE(compound && !PageTransHuge(page), page); This is meant to check for either HugeTLB pages or THP when a compound page is passed in. Unfortunately, if one disables CONFIG_TRANSPARENT_HUGEPAGE, then PageTransHuge(.) will always return false, provoking BUGs when one runs the libhugetlbfs test suite. This patch replaces PageTransHuge(), with PageHead() which will work for both HugeTLB and THP.

PageTransCompound() doesn't distinguish THP from from any other type of compound pages. This can lead to false-positive VM_BUG_ON() in page_add_file_rmap() if called on compound page from a driver[1]. I think we can exclude such cases by checking if the page belong to a mapping. The VM_BUG_ON_PAGE() is downgraded to VM_WARN_ON_ONCE(). This path should not cause any harm to non-THP page, but good to know if we step on anything else.

The newly introduced shmem_huge_enabled() function has two definitions, but neither of them is visible if CONFIG_SYSFS is disabled, leading to a build error: mm/khugepaged.o: In function `khugepaged': khugepaged.c:(.text.khugepaged+0x3ca): undefined reference to `shmem_huge_enabled' This changes the #ifdef guards around the definition to match those that are used in the header file.

Original patch: https://lkml.org/lkml/2016/8/4/32 If riocm_ch_alloc() fails then we end up dereferencing the error pointer. The problem is that we're not unwinding in the reverse order from how we allocate things so it gets confusing. I've changed this around so now "ch" is NULL when we are done with it after we call riocm_put_channel(). That way we can check if it's NULL and avoid calling riocm_put_channel() on it twice. I renamed err_nodev to err_put_new_ch so that it better reflects what the goto does. Then because we had flipping things around, it means we don't neeed to initialize the pointers to NULL and we can remove an if statement and pull things in an indent level.

The unit tests crash when hotplug races the previous probe. This race requires that the loading of the nfit_test module be terminated with SIGTERM, and the module to be unloaded while the ars scan is still running. In contrast to the normal nfit driver, the unit test calls acpi_nfit_init() twice to simulate hotplug, whereas the nominal case goes through the acpi_nfit_notify() event handler. The acpi_nfit_notify() path is careful to flush the previous region registration before servicing the hotplug event. The unit test was missing this guarantee.

Clearly QEMU is very permissive in how its PL310 model may be set up, but the real hardware turns out to be far more particular about things actually being correct. Fix up the DT description so that the real thing actually boots: - The arm,data-latency and arm,tag-latency properties need 3 cells to be valid, otherwise we end up retaining the default 8-cycle latencies which leads pretty quickly to lockup. - The arm,dirty-latency property is only relevant to L210/L220, so get rid of it. - The cache geometry override also leads to lockup and/or general misbehaviour. Irritatingly, the manual doesn't state the actual PL310 configuration, but based on the boardfile code and poking registers from the Boot Monitor, it would seem to be 8 sets of 16KB ways. With that, we can successfully boot to enjoy the fun of mismatched FPUs...

c90bb7b9 enabled the high speed UARTs of the Jetson TK1. Due to a merge quirk, wrong addresses were introduced. Fix it and use the correct addresses. Thierry let me know, that there is another patch (b5896f67 in linux-next) in preparation which removes all the '0,' prefixes of unit addresses on Tegra124 and is planned to go upstream in 4.8, so this patch will get reverted then. But for the moment, this patch is necessary to fix current misbehaviour.

The machine specific header files are exported for traditional platforms, but not for the ones that use ARCH_MULTIPLATFORM, as they could conflict with one another. In case of ARM_SINGLE_ARMV7M, we end up also exporting them, but that appears to be a mistake, and we should treat it the same way as ARCH_MULTIPLATFORM here. 'make W=1' warns about this because it passes -Wmissing-includes to gcc and the directories are not actually present. Signed-off-by: NArnd Bergmann <arnd@arndb.de>
