2020-03-25MIPS/tlbex: Fix LDDIR usage in setup_pw() for Loongson-3Huacai Chen
LDDIR/LDPTE is Loongson-3's acceleration for Page Table Walking. If BD (Base Directory, the 4th page directory) is not enabled, then GDOffset is biased by BadVAddr[63:62]. So, if GDOffset (aka. BadVAddr[47:36] for Loongson-3) is big enough, "0b11(BadVAddr[63:62])|BadVAddr[47:36]|...." can far beyond pg_swapper_dir. This means the pg_swapper_dir may NOT be accessed by LDDIR correctly, so fix it by set PWDirExt in CP0_PWCtl.

2020-03-25MIPS: do not compile generic functions for CONFIG_CAVIUM_OCTEON_SOCMasahiro Yamada
MIPS provides multiple definitions for the following functions: fw_init_cmdline __delay __udelay __ndelay memmove __rmemcpy memcpy __copy_user The generic ones are defined in lib-y objects, which are overridden by the Octeon ones when CONFIG_CAVIUM_OCTEON_SOC is enabled. The use of EXPORT_SYMBOL in static libraries potentially causes a problem for the llvm linker [1]. So, I want to forcibly link lib-y objects to vmlinux when CONFIG_MODULES=y. As a groundwork, we must fix multiple definitions that have previously been hidden by lib-y. If you look at lib/string.c, arch can define __HAVE_ARCH_* to opt out the generic implementation. Similarly, this commit adds CONFIG_HAVE_PLAT_* to allow a platform to opt out the MIPS generic code.

2020-03-25block/diskstats: replace time_in_queue with sum of request timesKonstantin Khlebnikov
Column "time_in_queue" in diskstats is supposed to show total waiting time of all requests. I.e. value should be equal to the sum of times from other columns. But this is not true, because column "time_in_queue" is counted separately in jiffies rather than in nanoseconds as other times. This patch removes redundant counter for "time_in_queue" and shows total time of read, write, discard and flush requests.

2020-03-25block/diskstats: more accurate approximation of io_ticks for slow disksKonstantin Khlebnikov
Currently io_ticks is approximated by adding one at each start and end of requests if jiffies counter has changed. This works perfectly for requests shorter than a jiffy or if one of requests starts/ends at each jiffy. If disk executes just one request at a time and they are longer than two jiffies then only first and last jiffies will be accounted. Fix is simple: at the end of request add up into io_ticks jiffies passed since last update rather than just one jiffy. Example: common HDD executes random read 4k requests around 12ms. fio --name=test --filename=/dev/sdb --rw=randread --direct=1 --runtime=30 & iostat -x 10 sdb Note changes of iostat's "%util" 8,43% -> 99,99% before/after patch: Before: Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await r_await w_await svctm %util sdb 0,00 0,00 82,60 0,00 330,40 0,00 8,00 0,96 12,09 12,09 0,00 1,02 8,43 After: Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await r_await w_await svctm %util sdb 0,00 0,00 82,50 0,00 330,00 0,00 8,00 1,00 12,10 12,10 0,00 12,12 99,99 Now io_ticks does not loose time between start and end of requests, but for queue-depth > 1 some I/O time between adjacent starts might be lost. For load estimation "%util" is not as useful as average queue length, but it clearly shows how often disk queue is completely empty.

Commit d4ec0cb05064 ("ARM: dts: exynos: Add support for the touch-sensitive buttons on Midas family") added a new fixed regulator ("voltage-regulator-6") to base "midas" .dtsi, but it didn't update the clients of that .dtsi, which define their own fixed regulators starting from the "voltage-regulator-6". This results in aliasing of the regulator dt nodes and breaks operation of OLED panel due to lack of power supply. Fix this by increasing the numbers in the fixed regulator names for those boards.

The driver change was picked up right before the previous -rc6 and the DT bindings and DT changes were not picked up. The goal is to have all the changes in the same release, that is v5.6. * tag 'sunxi-fixes-for-5.6-2' of git://git.kernel.org/pub/scm/linux/kernel/git/sunxi/linux: ARM: dts: sun8i: a33: add the new SS compatible dt-bindings: crypto: add new compatible for A33 SS Link: https://lore.kernel.org/r/20200313060727.GA23962@wens.csie.org Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2020-03-25cpu/hotplug: Hide cpu_up/down()Qais Yousef
Use separate functions for the device core to bring a CPU up and down. Users outside the device core must use add/remove_cpu() which will take care of extra housekeeping work like keeping sysfs in sync. Make cpu_up/down() static and replace the extra layer of indirection.

The core device API performs extra housekeeping bits that are missing from directly calling cpu_up/down(). See commit a6717c01ddc2 ("powerpc/rtas: use device model APIs and serialization during LPM") for an example description of what might go wrong.
