2017-02-10hwmon: (it87) Add support for IT8792EGuenter Roeck
The chip is similar to IT8732E, but supports only three fans and pwm outputs instead of four (the driver currently does not support the 4th fan and pwm output of IT8732E). Note that the chip ID is 0x8733, not 0x8792 as one would expect. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2017-02-10hwmon: (it87) Do not overwrite bit 2..6 of pwm control registersGuenter Roeck
In IT8620E, after setting pwm control to manual, it was observed that pwm values for fan 4..6 have reversed results (writing 0 results in fans running at full speed, writing 255 results in fans turned off). With the new PWM control, pwm polarity for pwm control 4..6 is specified in its pwm control registers. Those registers are overwritten when setting the pwm mode or the temperature mapping. Do not touch bit 2..6 of pwm control registers on register writes to fix the problem. Cc: stable@vger.kernel.org # 4.9+ Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2017-02-10hwmon: (it87) Fix pwm4 detection for IT8620 and IT8628Guenter Roeck
pwm4 is enabled if bit 2 of GPIO control register 4 is disabled, not when it is enabled. Since the check is for the skip condition, it is reversed. This applies to both IT8620 and IT8628.

2017-02-10hwmon: (it87) Ensure that pwm control cache is current before updating valuesGuenter Roeck

2017-02-10Btrfs: fix btrfs_decompress_buf2page()Omar Sandoval
If btrfs_decompress_buf2page() is handed a bio with its page in the middle of the working buffer, then we adjust the offset into the working buffer. After we copy into the bio, we advance the iterator by the number of bytes we copied. Then, we have some logic to handle the case of discontiguous pages and adjust the offset into the working buffer again. However, if we didn't advance the bio to a new page, we may enter this case in error, essentially repeating the adjustment that we already made when we entered the function. The end result is bogus data in the bio. Previously, we only checked for this case when we advanced to a new page, but the conversion to bio iterators changed that. This restores the old, correct behavior. A case I saw when testing with zlib was: buf_start = 42769 total_out = 46865 working_bytes = total_out - buf_start = 4096 start_byte = 45056 The condition (total_out > start_byte && buf_start < start_byte) is true, so we adjust the offset: buf_offset = start_byte - buf_start = 2287 working_bytes -= buf_offset = 1809 current_buf_start = buf_start = 42769 Then, we copy bytes = min(bvec.bv_len, PAGE_SIZE - buf_offset, working_bytes) = 1809 buf_offset += bytes = 4096 working_bytes -= bytes = 0 current_buf_start += bytes = 44578 After bio_advance(), we are still in the same page, so start_byte is the same. Then, we check (total_out > start_byte && current_buf_start < start_byte), which is true! So, we adjust the values again: buf_offset = start_byte - buf_start = 2287 working_bytes = total_out - start_byte = 1809 current_buf_start = buf_start + buf_offset = 45056 But note that working_bytes was already zero before this, so we should have stopped copying.

Jakub Kicinski says: ==================== Netronome NFP4000 and NFP6000 PF driver This is a base PF driver for Netronome NFP4000 and NFP6000 chips. This series doesn't add any exciting new features, it provides a foundation for supporting more advanced firmware applications. Patch 1 moves a bitfield-related helper from our BPF code to the global header. Patch 2 renames the kernel module and adds a new main file. We were considering 3-module approach (pf, vf, common netdev library) but ultimately settled on a single module to keep things simple. Patch 3 adds support for accessing chip internals. It provides a way of configuring access windows to different parts of chip memory and issuing pretty much any commands on chip's NoC. Patches 4, 5, 6, 7, 8 provide support for accessing and interpreting various hardware and firmware information structures. Patch 9 introduces service processor (NSP) ABI. This ABI gives us access to PHY/SFP module configuration and information as well as methods for unloading and loading application firmware. Patches 10 and 11 modify the existing netdev code to make it possible to support multi-port devices (sharing a PCI device). Patch 12 adds a new driver probe path which will be used for the PF PCI device IDs. It utilizes the newly added infrastructure and is able to load application FW and spawn netdevs for all card's ports. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2017-02-10nfp: add CPP access coreJakub Kicinski
Command Push Pull is the name of NFP's network on a chip. PCIe PF can access the interconnect through a number of mappings controlled via Base Access Registers. BARs allow the PF to issue pretty much any command or address any memory on the chip. Add appropriate logic and a handful of helper for simple operations like reading scalars from memories.
