Add new trace points for the start and end of enabling bypass on a regulator, to allow monitoring of when regulators are moved into bypass and how long that takes.

Merge series "Fix regulators coupling for Exynos5800" from Marek Szyprowski <m.szyprowski@samsung.com>: Hi! This patchset is another attempt to fix the regulator coupling on Exynos5800/5422 SoCs. Here are links to the previous attempts: https://lore.kernel.org/linux-samsung-soc/20191008101709.qVNy8eijBi0LynOteWFMnTg4GUwKG599n6OyYoX1Abs@z/ https://lore.kernel.org/lkml/20191017102758.8104-1-m.szyprowski@samsung.com/ https://lore.kernel.org/linux-pm/cover.1589528491.git.viresh.kumar@linaro.org/ https://lore.kernel.org/linux-pm/20200528131130.17984-1-m.szyprowski@samsung.com/ The problem is with "vdd_int" regulator coupled with "vdd_arm" on Odroid XU3/XU4 boards family. "vdd_arm" is handled by CPUfreq. "vdd_int" is handled by devfreq. CPUfreq initialized quite early during boot and it starts changing OPPs and "vdd_arm" value. Sometimes CPU activity during boot goes down and some low-frequency OPPs are selected, what in turn causes lowering "vdd_arm". This happens before devfreq applies its requirements on "vdd_int". Regulator balancing code reduces "vdd_arm" voltage value, what in turn causes lowering "vdd_int" value to the lowest possible value. This is much below the operation point of the wcore bus, which still runs at the highest frequency. The issue was hard to notice because in the most cases the board managed to boot properly, even when the regulator was set to lowest value allowed by the regulator constraints. However, it caused some random issues, which can be observed as "Unhandled prefetch abort" or low USB stability. Adding more and more special cases to the generic code has been rejected, so the only way to ensure the desired behavior on Exynos5800-based SoCs is to make a custom regulator coupler driver.

The max8998 has a current regulator for charging control. The charger driver in drivers/power/supply/max8998_charger.c has a comment in it stating that 'charger control is done by a current regulator "CHARGER"', but this regulator was never added until now. The current values have been extracted from a downstream driver for the SGH-T959V.

Merge series "MAINTAINER entries for few ROHM power devices" from Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com>: Add maintainer entries to a few ROHM devices and Linear Ranges Linear Ranges helpers were refactored out of regulator core to lib so that other drivers could utilize them too. (I guess power/supply drivers and possibly clk drivers can benefit from them). As regulators is currently the main user it makes sense the changes to linear_ranges go through Mark's tree. During past two years few ROHM PMIC drivers have been added to mainstream. They deserve a supporter from ROHM side too :) Patch 1: Maintainer entries for few ROHM IC drivers Patch 2: Maintainer entry for linear ranges helpers --- Matti Vaittinen (2): MAINTAINERS: Add entry for ROHM power management ICs MAINTAINERS: Add maintainer entry for linear ranges helper MAINTAINERS | 37 +++++++++++++++++++++++++++++++++++++ 1 file changed, 37 insertions(+) base-commit: b9bbe6ed -- 2.21.0 -- Matti Vaittinen, Linux device drivers ROHM Semiconductors, Finland SWDC Kiviharjunlenkki 1E 90220 OULU FINLAND ~~~ "I don't think so," said Rene Descartes.

I goofed when I added mm->user_ns support to would_dump. I missed the fact that in the case of binfmt_loader, binfmt_em86, binfmt_misc, and binfmt_script bprm->file is reassigned. Which made the move of would_dump from setup_new_exec to __do_execve_file before exec_binprm incorrect as it can result in would_dump running on the script instead of the interpreter of the script. The net result is that the code stopped making unreadable interpreters undumpable. Which allows them to be ptraced and written to disk without special permissions. Oops. The move was necessary because the call in set_new_exec was after bprm->mm was no longer valid. To correct this mistake move the misplaced would_dump from __do_execve_file into flos_old_exec, before exec_mmap is called. I tested and confirmed that without this fix I can attach with gdb to a script with an unreadable interpreter, and with this fix I can not.

Pull RISC-V fixes from Palmer Dabbelt: "A handful of build fixes, all found by Huawei's autobuilder. None of these patches should have any functional impact on kernels that build, and they're mostly related to various features intermingling with !MMU. While some of these might be better hoisted to generic code, it seems better to have the simple fixes in the meanwhile. As far as I know these are the only outstanding patches for 5.7" * tag 'riscv-for-linus-5.7-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: riscv: mmiowb: Fix implicit declaration of function 'smp_processor_id' riscv: pgtable: Fix __kernel_map_pages build error if NOMMU riscv: Make SYS_SUPPORTS_HUGETLBFS depends on MMU riscv: Disable ARCH_HAS_DEBUG_VIRTUAL if NOMMU riscv: Add pgprot_writecombine/device and PAGE_SHARED defination if NOMMU riscv: stacktrace: Fix undefined reference to `walk_stackframe' riscv: Fix unmet direct dependencies built based on SOC_VIRT riscv: perf: RISCV_BASE_PMU should be independent riscv: perf_event: Make some funciton static

Depending on the WRIOP version, the buffer size on the RX path must by a multiple of 64 or 256. Handle this restriction properly by aligning down the buffer size to the necessary value. Also, use the new buffer size dynamically computed instead of the compile time one.
