In some cases the previous algorithm would not return the closest approximation. This would happen when a semi-convergent was the closest, as the previous algorithm would only consider convergents. As an example, consider an initial value of 5/4, and trying to find the closest approximation with a maximum of 4 for numerator and denominator. The previous algorithm would return 1/1 as the closest approximation, while this version will return the correct answer of 4/3. To do this, the main loop performs effectively the same operations as it did before. It must now keep track of the last three approximations, n2/d2 .. n0/d0, while before it only needed the last two. If an exact answer is not found, the algorithm will now calculate the best semi-convergent term, t, which is a single expression with two divisions: min((max_numerator - n0) / n1, (max_denominator - d0) / d1) This will be used if it is better than previous convergent. The test for this is generally a simple comparison, 2*t > a. But in an edge case, where the convergent's final term is even and the best allowable semi-convergent has a final term of exactly half the convergent's final term, the more complex comparison (d0*dp > d1*d) is used. I also wrote some comments explaining the code. While one still needs to look up the math elsewhere, they should help a lot to follow how the code relates to that math. This routine is used in two places in the video4linux code, but in those cases it is only used to reduce a fraction to lowest terms, which the existing code will do correctly. This could be done more efficiently with a different library routine but it would still be the Euclidean alogrithm at its heart. So no change. The remain users are places where a fractional PLL divider is programmed. What would happen is something asked for a clock of X MHz but instead gets Y MHz, where Y is close to X but not exactly due to the hardware limitations. After this change they might, in some cases, get Y' MHz, where Y' is a little closer to X then Y was. Users like this are: Three UARTs, in 8250_mid, 8250_lpss, and imx. One GPU in vp4_hdmi. And three clock drivers, clk-cdce706, clk-si5351, and clk-fractional-divider. The last is a generic clock driver and so would have more users referenced via device tree entries. I think there's a bug in that one, it's limiting an N bit field that is offset-by-1 to the range 0 .. (1<<N)-2, when it should be (1<<N)-1 as the upper limit. I have an IMX system, one of the UARTs using this, so I can provide a real example. If I request a custom baud rate of 1499978, the driver will program the PLL to produce a baud rate of 1500000. After this change, the fractional divider in the UART is programmed to a ratio of 65535/65536, which produces a baud rate of 1499977.0625. Closer to the requested value.

The introduction of the for_each_set_clump8 macro warrants test cases to verify the implementation. This patch adds test case checks for whether an out-of-bounds clump index is returned, a zero clump is returned, or the returned clump value differs from the expected clump value.

Pach series "Introduce the for_each_set_clump8 macro", v18. While adding GPIO get_multiple/set_multiple callback support for various drivers, I noticed a pattern of looping manifesting that would be useful standardized as a macro. This patchset introduces the for_each_set_clump8 macro and utilizes it in several GPIO drivers. The for_each_set_clump macro8 facilitates a for-loop syntax that iterates over a memory region entire groups of set bits at a time. For example, suppose you would like to iterate over a 32-bit integer 8 bits at a time, skipping over 8-bit groups with no set bit, where XXXXXXXX represents the current 8-bit group: Example: 10111110 00000000 11111111 00110011 First loop: 10111110 00000000 11111111 XXXXXXXX Second loop: 10111110 00000000 XXXXXXXX 00110011 Third loop: XXXXXXXX 00000000 11111111 00110011 Each iteration of the loop returns the next 8-bit group that has at least one set bit. The for_each_set_clump8 macro has four parameters: * start: set to the bit offset of the current clump * clump: set to the current clump value * bits: bitmap to search within * size: bitmap size in number of bits In this version of the patchset, the for_each_set_clump macro has been reimplemented and simplified based on the suggestions provided by Rasmus Villemoes and Andy Shevchenko in the version 4 submission. In particular, the function of the for_each_set_clump macro has been restricted to handle only 8-bit clumps; the drivers that use the for_each_set_clump macro only handle 8-bit ports so a generic for_each_set_clump implementation is not necessary. Thus, a solution for large clumps (i.e. those larger than the width of a bitmap word) can be postponed until a driver appears that actually requires such a generic for_each_set_clump implementation. For what it's worth, a semi-generic for_each_set_clump (i.e. for clumps smaller than the width of a bitmap word) can be implemented by simply replacing the hardcoded '8' and '0xFF' instances with respective variables. I have not yet had a need for such an implementation, and since it falls short of a true generic for_each_set_clump function, I have decided to forgo such an implementation for now. In addition, the bitmap_get_value8 and bitmap_set_value8 functions are introduced to get and set 8-bit values respectively. Their use is based on the behavior suggested in the patchset version 4 review. This patch (of 14): This macro iterates for each 8-bit group of bits (clump) with set bits, within a bitmap memory region. For each iteration, "start" is set to the bit offset of the found clump, while the respective clump value is stored to the location pointed by "clump". Additionally, the bitmap_get_value8 and bitmap_set_value8 functions are introduced to respectively get and set an 8-bit value in a bitmap memory region.

Git is gaining support to display the closest node to the diff in the hunk header via the 'dts' diff driver.

Fix coding style of "struct ctl_table" and "struct ctl_table_header" to have inline braces. Besides the wide use of this proposed cose style, this change helps to find at a glance the struct definition when navigating the code.

Currently gluing PDE into global /proc tree is done under lock, but changing ->nlink is not. Additionally struct proc_dir_entry::nlink is not atomic so updates can be lost. Link: http://lkml.kernel.org/r/20190925202436.GA17388@avx2Signed-off-by:
