2017-02-12m68k/atari: Modernize printing of kernel messagesGeert Uytterhoeven
- Convert from printk() to pr_*(), - Add missing continuations, to fix user-visible breakage, - Drop useless WARNING prefix, - Move trailing spaces to start of continuations. Note that the "Keyboard overrun" message will now only be generated when the kernel has been compiled for debugging.

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>

2017-02-10Btrfs: 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.
