2018-11-20drm/amdgpu: enable paging queue doorbell support v4Philip Yang
Because increase SDMA_DOORBELL_RANGE to add new SDMA doorbell for paging queue will break SRIOV, instead we can reserve and map two doorbell pages for amdgpu, paging queues doorbell index use same index as SDMA gfx queues index but on second page. For Vega20, after we change doorbell layout to increase SDMA doorbell for 8 SDMA RLC queues later, we could use new doorbell index for paging queue.

2018-11-20drm/amdgpu: Fix KFD doorbell SG BO mappingFelix Kuehling
This change prepares for adding SG BOs that will be used for mapping doorbells into GPUVM address space. This type of BO would be mistaken for an invalid userptr BO.

2018-11-20drm/amdkfd: Fix and simplify sync object handling for KFDFelix Kuehling
The adev parameter in amdgpu_sync_fence and amdgpu_sync_resv is only needed for updating sync->last_vm_update. This breaks if different adevs are passed to calls for the same sync object. Always pass NULL for calls from KFD because sync objects used for KFD don't belong to any particular device, and KFD doesn't need the sync->last_vm_update fence. This fixes kernel log warnings on multi-GPU systems after recent changes in amdgpu_amdkfd_gpuvm_restore_process_bos.

2018-11-20xfs: extent shifting doesn't fully invalidate page cacheDave Chinner
The extent shifting code uses a flush and invalidate mechainsm prior to shifting extents around. This is similar to what xfs_free_file_space() does, but it doesn't take into account things like page cache vs block size differences, and it will fail if there is a page that it currently busy. xfs_flush_unmap_range() handles all of these cases, so just convert xfs_prepare_shift() to us that mechanism rather than having it's own special sauce.

2018-11-20xfs: finobt AG reserves don't consider last AG can be a runtDave Chinner
The last AG may be very small comapred to all other AGs, and hence AG reservations based on the superblock AG size may actually consume more space than the AG actually has. This results on assert failures like: XFS: Assertion failed: xfs_perag_resv(pag, XFS_AG_RESV_METADATA)->ar_reserved + xfs_perag_resv(pag, XFS_AG_RESV_RMAPBT)->ar_reserved <= pag->pagf_freeblks + pag->pagf_flcount, file: fs/xfs/libxfs/xfs_ag_resv.c, line: 319 [ 48.932891] xfs_ag_resv_init+0x1bd/0x1d0 [ 48.933853] xfs_fs_reserve_ag_blocks+0x37/0xb0 [ 48.934939] xfs_mountfs+0x5b3/0x920 [ 48.935804] xfs_fs_fill_super+0x462/0x640 [ 48.936784] ? xfs_test_remount_options+0x60/0x60 [ 48.937908] mount_bdev+0x178/0x1b0 [ 48.938751] mount_fs+0x36/0x170 [ 48.939533] vfs_kern_mount.part.43+0x54/0x130 [ 48.940596] do_mount+0x20e/0xcb0 [ 48.941396] ? memdup_user+0x3e/0x70 [ 48.942249] ksys_mount+0xba/0xd0 [ 48.943046] __x64_sys_mount+0x21/0x30 [ 48.943953] do_syscall_64+0x54/0x170 [ 48.944835] entry_SYSCALL_64_after_hwframe+0x49/0xbe Hence we need to ensure the finobt per-ag space reservations take into account the size of the last AG rather than treat it like all the other full size AGs.

2018-11-20xfs: fix transient reference count error in xfs_buf_resubmit_failed_buffersDave Chinner
When retrying a failed inode or dquot buffer, xfs_buf_resubmit_failed_buffers() clears all the failed flags from the inde/dquot log items. In doing so, it also drops all the reference counts on the buffer that the failed log items hold. This means it can drop all the active references on the buffer and hence free the buffer before it queues it for write again. Putting the buffer on the delwri queue takes a reference to the buffer (so that it hangs around until it has been written and completed), but this goes bang if the buffer has already been freed. Hence we need to add the buffer to the delwri queue before we remove the failed flags from the log items attached to the buffer to ensure it always remains referenced during the resubmit process.

2018-11-20Documentation/security-bugs: Postpone fix publication in exceptional casesWill Deacon
At the request of the reporter, the Linux kernel security team offers to postpone the publishing of a fix for up to 5 business days from the date of a report. While it is generally undesirable to keep a fix private after it has been developed, this short window is intended to allow distributions to package the fix into their kernel builds and permits early inclusion of the security team in the case of a co-ordinated disclosure with other parties. Unfortunately, discussions with major Linux distributions and cloud providers has revealed that 5 business days is not sufficient to achieve either of these two goals. As an example, cloud providers need to roll out KVM security fixes to a global fleet of hosts with sufficient early ramp-up and monitoring. An end-to-end timeline of less than two weeks dramatically cuts into the amount of early validation and increases the chance of guest-visible regressions. The consequence of this timeline mismatch is that security issues are commonly fixed without the involvement of the Linux kernel security team and are instead analysed and addressed by an ad-hoc group of developers across companies contributing to Linux. In some cases, mainline (and therefore the official stable kernels) can be left to languish for extended periods of time. This undermines the Linux kernel security process and puts upstream developers in a difficult position should they find themselves involved with an undisclosed security problem that they are unable to report due to restrictions from their employer. To accommodate the needs of these users of the Linux kernel and encourage them to engage with the Linux security team when security issues are first uncovered, extend the maximum period for which fixes may be delayed to 7 calendar days, or 14 calendar days in exceptional cases, where the logistics of QA and large scale rollouts specifically need to be accommodated. This brings parity with the linux-distros@ maximum embargo period of 14 calendar days.

2018-11-20mtd: spi-nor: fix selection of uniform erase type in flexible confTudor.Ambarus@microchip.com
There are uniform, non-uniform and flexible erase flash configurations. The non-uniform erase types, are the erase types that can _not_ erase the entire flash by their own. As the code was, in case flashes had flexible erase capabilities (support both uniform and non-uniform erase types in the same flash configuration) and supported multiple uniform erase type sizes, the code did not sort the uniform erase types, and could select a wrong erase type size. Sort the uniform erase mask in case of flexible erase flash configurations, in order to select the best uniform erase type size. Uniform, non-uniform, and flexible configurations with just a valid uniform erase type, are not affected by this change. Uniform erase tested on mx25l3273fm2i-08g and sst26vf064B-104i/sn.

2018-11-20drm/i915: Write GPU relocs harder with gen3Chris Wilson
Under moderate amounts of GPU stress, we can observe on Bearlake and Pineview (later gen3 models) that we execute the following batch buffer before the write into the batch is coherent. Adding extra (tested with upto 32x) MI_FLUSH to either the invalidation, flush or both phases does not solve the incoherency issue with the relocations, but emitting the MI_STORE_DWORD_IMM twice does. So be it.

2018-11-19net/ibmnvic: Fix deadlock problem in resetJuliet Kim
This patch changes to use rtnl_lock only during a reset to avoid deadlock that could occur when a thread operating close is holding rtnl_lock and waiting for reset_lock acquired by another thread, which is waiting for rtnl_lock in order to set the number of tx/rx queues during a reset. Also, we now setting the number of tx/rx queues during a soft reset for failover or LPM events. Signed-off-by: Juliet Kim <julietk@linux.vnet.ibm.com> Signed-off-by: David S.

2018-11-19qed: Fix QM getters to always return a valid pqDenis Bolotin
The getter callers doesn't know the valid Physical Queues (PQ) values. This patch makes sure that a valid PQ will always be returned. The patch consists of 3 fixes: - When qed_init_qm_get_idx_from_flags() receives a disabled flag, it returned PQ 0, which can potentially be another function's pq. Verify that flag is enabled, otherwise return default start_pq. - When qed_init_qm_get_idx_from_flags() receives an unknown flag, it returned NULL and could lead to a segmentation fault. Return default start_pq instead. - A modulo operation was added to MCOS/VFS PQ getters to make sure the PQ returned is in range of the required flag.
