2020-07-28net: hns3: add reset check for VF updating port based VLANJian Shen
Currently hclgevf_update_port_base_vlan_info() may be called when VF is resetting, which may cause hns3_nic_net_open() being called twice unexpectedly. So fix it by adding a reset check for it, and extend critical region for rntl_lock in hclgevf_update_port_base_vlan_info().

2020-07-28net: hns3: fix a TX timeout issueYonglong Liu
When the queue depth and queue parameters are modified, there is a low probability that TX timeout occurs. The two operations cause the link to be down or up when the watchdog is still working. All queues are stopped when the link is down. After the carrier is on, all queues are woken up. If the watchdog detects the link between the carrier on and wakeup queues, a false TX timeout occurs. So fix this issue by modifying the sequence of carrier on and queue wakeup, which is symmetrical to the link down action.

2020-07-28mm/notifier: add migration invalidation typeRalph Campbell
Currently migrate_vma_setup() calls mmu_notifier_invalidate_range_start() which flushes all device private page mappings whether or not a page is being migrated to/from device private memory. In order to not disrupt device mappings that are not being migrated, shift the responsibility for clearing device private mappings to the device driver and leave CPU page table unmapping handled by migrate_vma_setup(). To support this, the caller of migrate_vma_setup() should always set struct migrate_vma::pgmap_owner to a non NULL value that matches the device private page->pgmap->owner. This value is then passed to the struct mmu_notifier_range with a new event type which the driver's invalidation function can use to avoid device MMU invalidations.

2020-07-28mm/migrate: add a flags parameter to migrate_vmaRalph Campbell
The src_owner field in struct migrate_vma is being used for two purposes, it acts as a selection filter for which types of pages are to be migrated and it identifies device private pages owned by the caller. Split this into separate parameters so the src_owner field can be used just to identify device private pages owned by the caller of migrate_vma_setup(). Rename the src_owner field to pgmap_owner to reflect it is now used only to identify which device private pages to migrate.

2020-07-28nouveau: fix storing invalid ptesRalph Campbell
When migrating a range of system memory to device private memory, some of the pages in the address range may not be migrating. In this case, the non migrating pages won't have a new GPU MMU entry to store but the nvif_object_ioctl() NVIF_VMM_V0_PFNMAP method doesn't check the input and stores a bad valid GPU page table entry. Fix this by skipping the invalid input PTEs when updating the GPU page tables.

Passing size to copy_user_dax implies it can copy variable sizes of data when in fact it calls copy_user_page() which is exactly a page. We are safe because the only caller uses PAGE_SIZE anyway so just remove the variable for clarity. While we are at it change copy_user_dax() to copy_cow_page_dax() to make it clear it is a singleton helper for this one case not implementing what dax_iomap_actor() does.

2020-07-28dax: print error message by pr_info() in __generic_fsdax_supported()Coly Li
In struct dax_operations, the callback routine dax_supported() returns a bool type result. For false return value, the caller has no idea whether the device does not support dax at all, or it is just some mis- configuration issue. An example is formatting an Ext4 file system on pmem device on top of a NVDIMM namespace by, # mkfs.ext4 /dev/pmem0 If the fs block size does not match kernel space memory page size (which is possible on non-x86 platform), mount this Ext4 file system will fail, # mount -o dax /dev/pmem0 /mnt mount: /mnt: wrong fs type, bad option, bad superblock on /dev/pmem0, missing codepage or helper program, or other error. And from the dmesg output there is only the following information, [ 307.853148] EXT4-fs (pmem0): DAX unsupported by block device. The above information is quite confusing. Because definitely the pmem0 device supports dax operation, and the super block is consistent as how it was created by mkfs.ext4. Indeed the failure is from __generic_fsdax_supported() by the following code piece, if (blocksize != PAGE_SIZE) { pr_debug("%s: error: unsupported blocksize for dax\n", bdevname(bdev, buf)); return false; } It is because the Ext4 block size is 4KB and kernel page size is 8KB or 16KB. It is not simple to make dax_supported() from struct dax_operations or __generic_fsdax_supported() to return exact failure type right now. So the simplest fix is to use pr_info() to print all the error messages inside __generic_fsdax_supported(). Then users may find informative clue from the kernel message at least. Message printed by pr_debug() is very easy to be ignored by users. This patch prints error message by pr_info() in __generic_fsdax_supported(), when then mount fails, following lines can be found from dmesg output, [ 2705.500885] pmem0: error: unsupported blocksize for dax [ 2705.500888] EXT4-fs (pmem0): DAX unsupported by block device. Now the users may have idea the mount failure is from pmem driver for unsupported block size.

2020-07-28orangefs: posix acl fix...Mike Marshall
Al Viro pointed out that I broke some acl functionality... * ACLs could not be fully removed * posix_acl_chmod would be called while the old ACL was still cached * new mode propagated to orangefs server before ACL. ... when I tried to make sure that modes that got changed as a result of ACL-sets would be sent back to the orangefs server. Not wanting to try and change the code without having some cases to test it with, I began to hunt for setfacl examples that were expressible in pure mode. Along the way I found examples like the following which confused me: user A had a file (/home/A/asdf) with mode 740 user B was in user A's group user C was not in user A's group setfacl -m u:C:rwx /home/A/asdf The above setfacl caused ls -l /home/A/asdf to show a mode of 770, making it appear that all users in user A's group now had full access to /home/A/asdf, however, user B still only had read acces. Madness. Anywho, I finally found that the above (whacky as it is) appears to be "posixly on purpose" and explained in acl(5): If the ACL has an ACL_MASK entry, the group permissions correspond to the permissions of the ACL_MASK entry.

2020-07-28spi: spi-topcliff-pch: drop call to wakeup-disableVaibhav Gupta
Before generic upgrade, both .suspend() and .resume() were invoking pci_enable_wake(pci_dev, PCI_D3hot, 0). Hence, disabling wakeup in both states. (Normal trend is .suspend() enables and .resume() disables the wakeup.) This was ambiguous and may be buggy. Instead of replicating the legacy behavior, drop the wakeup-disable call.

2020-07-28spi: spidev: Align buffers for DMAChristian Eggers
Simply copying all xfers from userspace into one bounce buffer causes alignment problems if the SPI controller uses DMA. Ensure that all transfer data blocks within the rx and tx bounce buffers are aligned for DMA (according to ARCH_KMALLOC_MINALIGN). Alignment may increase the usage of the bounce buffers. In some cases, the buffers may need to be increased using the "bufsiz" module parameter.

Sridharan <ranjani.sridharan@linux.intel.com>: This set of patches is required for facilitating system S0ix entry when the DSP is in D0I3. This first patch adds the missing CORB/RIRB DMA stop and restart to the suspend/resume sequence along with powering up/down the links. The second patch ensures that the FW traces are disabled when the system enters S0ix with the DSP in D0I3.
