2018-03-06media: em28xx-dvb: simplify DVB module probing logicMauro Carvalho Chehab
The module probing logic there is a way more complex than it should be, and requires some special magic to avoid stack overflows when KASAN is enabled. Solve it by creating ancillary functions to setup the platform data and request module. Now, the probing functions are cleaner and easier to understand. As a side effect, the size of the module was reduced by about 9.7% on x86_64: Before this patch: text data bss dec hex filename 51090 14192 96 65378 ff62 drivers/media/usb/em28xx/em28xx-dvb.o After this patch: text data bss dec hex filename 44743 14192 96 59031 e697 drivers/media/usb/em28xx/em28xx-dvb.o Tested with a PCTV 461e device.

2018-03-06media: dvb-core: add helper functions for I2C bindingMauro Carvalho Chehab
The dvb_attach()/dvb_detach() methods are ugly hacks designed to keep using the I2C low-level API. The proper way is to do I2C bus bindings instead. Several modules were already converted to use it. Yet, it is painful to use it, as lots of code need to be duplicated. Make it easier by providing two new helper functions: - dvb_module_probe() - dvb_module_release() Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

2018-03-06media: lgdt3306a: Add QAM AUTO supportBrad Love
As configured currently, modulation in the driver is set to auto detect, no matter what the user sets modulation to. This leads to both QAM64 and QAM256 having the same effect. QAM AUTO is explicitly added here for compatibility with scanning software who can use AUTO instead of doing essentially the same scan twice. Also included is a module option to enforce a specific QAM modulation if desired. The true modulation is read before calculating the snr. Changes are backwards compatible with current behaviour.

2018-03-06media: lgdt3306a: Set fe ops.release to NULL if probedBrad Love
If release is part of frontend ops then it is called in the course of dvb_frontend_detach. The process also decrements the module usage count. The problem is if the lgdt3306a driver is reached via i2c_new_device, then when it is eventually destroyed remove is called, which further decrements the module usage count to negative. After this occurs the driver is in a bad state and no longer works. Also fixed by NULLing out the release callback is a double kfree of state, which introduces arbitrary oopses/GPF. This problem is only currently reachable via the em28xx driver.

2018-03-06media: ABS macro parameter parenthesizationDan Gopstein
Replace usages of the locally defined ABS() macro with calls to the canonical abs() from kernel.h and remove the old definitions of ABS() This change was originally motivated by two local definitions of the ABS (absolute value) macro that fail to parenthesize their parameter properly. This can lead to a bad expansion for low-precedence expression arguments. For example: ABS(1-2) currently expands to ((1-2) < 0 ? (-1-2) : (1-2)) which evaluates to -3. But the correct expansion would be ((1-2) < 0 ? -(1-2) : (1-2)) which evaluates to 1. Signed-off-by: Dan Gopstein <dgopstein@nyu.edu> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

2018-03-02libnvdimm: re-enable deep flush for pmem devices via fsync()Dave Jiang
Re-enable deep flush so that users always have a way to be sure that a write makes it all the way out to media. Writes from the PMEM driver always arrive at the NVDIMM since movnt is used to bypass the cache, and the driver relies on the ADR (Asynchronous DRAM Refresh) mechanism to flush write buffers on power failure. The Deep Flush mechanism is there to explicitly write buffers to protect against (rare) ADR failure. This change prevents a regression in deep flush behavior so that applications can continue to depend on fsync() as a mechanism to trigger deep flush in the filesystem-DAX case.

2018-03-02vfio: disable filesystem-dax page pinningDan Williams
Filesystem-DAX is incompatible with 'longterm' page pinning. Without page cache indirection a DAX mapping maps filesystem blocks directly. This means that the filesystem must not modify a file's block map while any page in a mapping is pinned. In order to prevent the situation of userspace holding of filesystem operations indefinitely, disallow 'longterm' Filesystem-DAX mappings. RDMA has the same conflict and the plan there is to add a 'with lease' mechanism to allow the kernel to notify userspace that the mapping is being torn down for block-map maintenance. Perhaps something similar can be put in place for vfio. Note that xfs and ext4 still report: "DAX enabled. Warning: EXPERIMENTAL, use at your own risk" ...at mount time, and resolving the dax-dma-vs-truncate problem is one of the last hurdles to remove that designation.

The error message: [Fri Feb 16 13:42:13 2018] i2c-thunderx 0000:01:09.4: unhandled state: 0 is mis-leading as state 0 (bus error) is not an unknown state.
