2019-03-18arm64: dts: rockchip: Rename vcc_sys into vcc5v0_sys on rk3399-rock960Jagan Teki
It is always better practice to follow regulator naming conventions as per the schematics for future references. So, rename vcc_sys into vcc5v0_sys as per rk3399 power diagram of rock960 schematics.

2019-03-18arm64: dts: rockchip: Add capacity-dmips-mhz attributes to rk3399Marc Zyngier
The RK3399 has the interesting property to be a so called "big-little" system, where not all the CPUs are equal (the A53s are much weaker than the A72s). So far, we're not telling the OS that there is such a difference in processing capacity, and Linux assumes that they are equal. Too bad. Let's tell the OS about this by using the capacity-dmips-mhz property. The values used here are those used on the Juno platform, which is quite similar. This leads to the scheduler knowing that it can pack more tasks on the A72s, and leads to a better interactive experience.

2019-03-18staging: comedi: ni_mio_common: Fix divide-by-zero for DIO cmdtestIan Abbott
`ni_cdio_cmdtest()` validates Comedi asynchronous commands for the DIO subdevice (subdevice 2) of supported National Instruments M-series cards. It is called when handling the `COMEDI_CMD` and `COMEDI_CMDTEST` ioctls for this subdevice. There are two causes for a possible divide-by-zero error when validating that the `stop_arg` member of the passed-in command is not too large. The first cause for the divide-by-zero is that calls to `comedi_bytes_per_scan()` are only valid once the command has been copied to `s->async->cmd`, but that copy is only done for the `COMEDI_CMD` ioctl. For the `COMEDI_CMDTEST` ioctl, it will use whatever was left there by the previous `COMEDI_CMD` ioctl, if any. (This is very likely, as it is usual for the application to use `COMEDI_CMDTEST` before `COMEDI_CMD`.) If there has been no previous, valid `COMEDI_CMD` for this subdevice, then `comedi_bytes_per_scan()` will return 0, so the subsequent division in `ni_cdio_cmdtest()` of `s->async->prealloc_bufsz / comedi_bytes_per_scan(s)` will be a divide-by-zero error. To fix this error, call a new function `comedi_bytes_per_scan_cmd(s, cmd)`, based on the existing `comedi_bytes_per_scan(s)` but using a specified `struct comedi_cmd` for its calculations. (Also refactor `comedi_bytes_per_scan()` to call the new function.) Once the first cause for the divide-by-zero has been fixed, the second cause is that `comedi_bytes_per_scan_cmd()` can legitimately return 0 if the `scan_end_arg` member of the `struct comedi_cmd` being tested is 0. Fix it by only performing the division (and validating that `stop_arg` is no more than the maximum value) if `comedi_bytes_per_scan_cmd()` returns a non-zero value.

To prevent a hardware memory leak when a DEVX DCT object is destroyed without calling DRAIN DCT before, (e.g. under cleanup flow), need to manage its creation and destruction via mlx5 core. In that case the DRAIN DCT command will be called and only once that it will be completed the DESTROY DCT command will be called. Otherwise, the DESTROY DCT may fail and a hardware leak may occur. As of that change the DRAIN DCT command should not be exposed any more from DEVX, it's managed internally by the driver to work as expected by the device specification.

2019-03-17xfs: don't trip over uninitialized buffer on extent read of corrupted inodeBrian Foster
We've had rather rare reports of bmap btree block corruption where the bmap root block has a level count of zero. The root cause of the corruption is so far unknown. We do have verifier checks to detect this form of on-disk corruption, but this doesn't cover a memory corruption variant of the problem. The latter is a reasonable possibility because the root block is part of the inode fork and can reside in-core for some time before inode extents are read. If this occurs, it leads to a system crash such as the following: BUG: unable to handle kernel paging request at ffffffff00000221 PF error: [normal kernel read fault] ... RIP: 0010:xfs_trans_brelse+0xf/0x200 [xfs] ... Call Trace: xfs_iread_extents+0x379/0x540 [xfs] xfs_file_iomap_begin_delay+0x11a/0xb40 [xfs] ? xfs_attr_get+0xd1/0x120 [xfs] ? iomap_write_begin.constprop.40+0x2d0/0x2d0 xfs_file_iomap_begin+0x4c4/0x6d0 [xfs] ? __vfs_getxattr+0x53/0x70 ? iomap_write_begin.constprop.40+0x2d0/0x2d0 iomap_apply+0x63/0x130 ? iomap_write_begin.constprop.40+0x2d0/0x2d0 iomap_file_buffered_write+0x62/0x90 ? iomap_write_begin.constprop.40+0x2d0/0x2d0 xfs_file_buffered_aio_write+0xe4/0x3b0 [xfs] __vfs_write+0x150/0x1b0 vfs_write+0xba/0x1c0 ksys_pwrite64+0x64/0xa0 do_syscall_64+0x5a/0x1d0 entry_SYSCALL_64_after_hwframe+0x49/0xbe The crash occurs because xfs_iread_extents() attempts to release an uninitialized buffer pointer as the level == 0 value prevented the buffer from ever being allocated or read. Change the level > 0 assert to an explicit error check in xfs_iread_extents() to avoid crashing the kernel in the event of localized, in-core inode corruption.
