Add add_memory_resource() to add memory using an existing "System RAM" resource. This is useful if the memory region is being located by finding a free resource slot with allocate_resource(). Xen guests will make use of this in their balloon driver to hotplug arbitrary amounts of memory in response to toolstack requests.

ACPI SSCN/FMCN methods were originally added because then the platform can provide the most accurate HCNT/LCNT values to the driver. However, this seems not to be true for Dell Inspiron 7348 where using these causes the touchpad to fail in boot: i2c_hid i2c-DLL0675:00: failed to retrieve report from device. i2c_designware INT3433:00: i2c_dw_handle_tx_abort: lost arbitration i2c_hid i2c-DLL0675:00: failed to retrieve report from device. i2c_designware INT3433:00: controller timed out The values received from ACPI are (in fast mode): HCNT: 72 LCNT: 160 this translates to following timings (input clock is 100MHz on Broadwell): tHIGH: 720 ns (spec min 600 ns) tLOW: 1600 ns (spec min 1300 ns) Bus period: 2920 ns (assuming 300 ns tf and tr) Bus speed: 342.5 kHz Both tHIGH and tLOW are within the I2C specification. The calculated values when ACPI parameters are not used are (in fast mode): HCNT: 87 LCNT: 159 which translates to: tHIGH: 870 ns (spec min 600 ns) tLOW: 1590 ns (spec min 1300 ns) Bus period 3060 ns (assuming 300 ns tf and tr) Bus speed 326.8 kHz These values are also within the I2C specification. Since both ACPI and calculated values meet the I2C specification timing requirements it is hard to say why the touchpad does not function properly with the ACPI values except that the bus speed is higher in this case (but still well below the max 400kHz). Solve this by adding DMI quirk to the driver that disables using ACPI parameters on this particulare machine.

Commit 3716001b ("deb-pkg: add source package") added the ability to create a debian changelog file. This exposed that previously the builddeb script hasn't cleared debian/files between builds. As debian/files keeps accumulating entries, the changes file will end up growing indefinelty. With outdated entries in debian/files, builddeb script will exit with failure. This regression impacts those who use "make deb-pkg" target to build kernel into a .deb package and never use "make mrproper" or other means to clean kernel tree from generated directories.

Commit 6afdb859 ("mm: do not ignore mapping_gfp_mask in page cache allocation paths") has caught some users of hardcoded GFP_KERNEL used in the page cache allocation paths. This, however, wasn't complete and there were others which went unnoticed. Dave Chinner has reported the following deadlock for xfs on loop device: : With the recent merge of the loop device changes, I'm now seeing : XFS deadlock on my single CPU, 1GB RAM VM running xfs/073. : : The deadlocked is as follows: : : kloopd1: loop_queue_read_work : xfs_file_iter_read : lock XFS inode XFS_IOLOCK_SHARED (on image file) : page cache read (GFP_KERNEL) : radix tree alloc : memory reclaim : reclaim XFS inodes : log force to unpin inodes : <wait for log IO completion> : : xfs-cil/loop1: <does log force IO work> : xlog_cil_push : xlog_write : <loop issuing log writes> : xlog_state_get_iclog_space() : <blocks due to all log buffers under write io> : <waits for IO completion> : : kloopd1: loop_queue_write_work : xfs_file_write_iter : lock XFS inode XFS_IOLOCK_EXCL (on image file) : <wait for inode to be unlocked> : : i.e. the kloopd, with it's split read and write work queues, has : introduced a dependency through memory reclaim. i.e. that writes : need to be able to progress for reads make progress. : : The problem, fundamentally, is that mpage_readpages() does a : GFP_KERNEL allocation, rather than paying attention to the inode's : mapping gfp mask, which is set to GFP_NOFS. : : The didn't used to happen, because the loop device used to issue : reads through the splice path and that does: : : error = add_to_page_cache_lru(page, mapping, index, : GFP_KERNEL & mapping_gfp_mask(mapping)); This has changed by commit aa4d8616 ("block: loop: switch to VFS ITER_BVEC"). This patch changes mpage_readpage{s} to follow gfp mask set for the mapping. There are, however, other places which are doing basically the same. lustre:ll_dir_filler is doing GFP_KERNEL from the function which apparently uses GFP_NOFS for other allocations so let's make this consistent. cifs:readpages_get_pages is called from cifs_readpages and __cifs_readpages_from_fscache called from the same path obeys mapping gfp. ramfs_nommu_expand_for_mapping is hardcoding GFP_KERNEL as well regardless it uses mapping_gfp_mask for the page allocation. ext4_mpage_readpages is the called from the page cache allocation path same as read_pages and read_cache_pages As I've noticed in my previous post I cannot say I would be happy about sprinkling mapping_gfp_mask all over the place and it sounds like we should drop gfp_mask argument altogether and use it internally in __add_to_page_cache_locked that would require all the filesystems to use mapping gfp consistently which I am not sure is the case here. From a quick glance it seems that some file system use it all the time while others are selective.

This covers only the simplest case - an object size sized write, but it's still useful in tiering setups when EC is used for the base tier as writefull op can be proxied, saving an object promotion. Even though updating ceph_osdc_new_request() to allow writefull should just be a matter of fixing an assert, I didn't do it because its only user is cephfs. All other sites were updated.

When we create a generic MSI domain, that MSI_FLAG_USE_DEF_CHIP_OPS is set, and that any of .mask or .unmask are NULL in the irq_chip structure, we set them to pci_msi_[un]mask_irq. This is a bad idea for at least two reasons: - PCI_MSI might not be selected, kernel fails to build (yes, this is legitimate, at least on arm64!) - This may not be a PCI/MSI domain at all (platform MSI, for example) Either way, this looks wrong. Move the overriding of mask/unmask to the PCI counterpart, and panic is any of these two methods is not set in the core code (they really should be present).

This will go away in 4.4 when we put in support for namespaces in RoCE devices. The last one is large in terms of lines, but is all legal and no functional changes. Cisco needed to update their files to be more specific about their license. They had intended the files to be dual licensed as GPL/BSD all along, and specified that in their module license tag, but their file headers were not up to par. They contacted all of the contributors to get agreement and then submitted a patch to update the license headers in the files. Summary: - Work around connection namespace lookup bug related to RoCE - Change usnic license to Dual GPL/BSD (was intended to be that way all along, but wasn't clear, permission from contributors was chased down) - Fix an issue between NFSoRDMA and mlx5 that could cause an oops - Fix leak of sendonly multicast groups" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: IB/ipoib: For sendonly join free the multicast group on leave IB/cma: Accept connection without a valid netdev on RoCE xprtrdma: Don't require LOCAL_DMA_LKEY support for fastreg usnic: add missing clauses to BSD license

The vmstat code uses "schedule_delayed_work_on()" to do the initial startup of the delayed work on the right CPU, but then once it was started it would use the non-cpu-specific "schedule_delayed_work()" to re-schedule it on that CPU. That just happened to schedule it on the same CPU historically (well, in almost all situations), but the code _requires_ this work to be per-cpu, and should say so explicitly rather than depend on the non-cpu-specific scheduling to schedule on the current CPU. The timer code is being changed to not be as single-minded in always running things on the calling CPU. See also commit 874bbfe6 ("workqueue: make sure delayed work run in local cpu") that for now maintains the local CPU guarantees just in case there are other broken users that depended on the accidental behavior.

Pull workqueue fixlet from Tejun Heo: "Single patch to make delayed work always be queued on the local CPU" This is not actually something we should guarantee, but it's something we by accident have historically done, and at least one call site has grown to depend on it. I'm going to fix that known broken callsite, but in the meantime this makes the accidental behavior be explicit, just in case there are other cases that might depend on it. * 'for-4.3-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: workqueue: make sure delayed work run in local cpu
