git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM SoC fixes from Olof Johansson: "I've been sitting on these longer than I meant, so the patch count is a bit higher than ideal for this part of the release. There's also some reverts of double-applied patches that brings the diffstat up a bit. With that said, the biggest changes are: - Revert of duplicate i2c device addition on two Aspeed (BMC) Devicetrees. - Move of two device nodes that got applied to the wrong part of the tree on ASpeed G6. - Regulator fix for Beaglebone X15 (adding 12/5V supplies) - Use interrupts for keys on Amlogic SM1 to avoid missed polls In addition to that, there is a collection of smaller DT fixes: - Power supply assignment fixes for i.MX6 - Fix of interrupt line for magnetometer on i.MX8 Librem5 devkit - Build fixlets (selects) for davinci/omap2+ - More interrupt number fixes for Stratix10, Amlogic SM1, etc. - ... and more similar fixes across different platforms And some non-DT stuff: - optee fix to register multiple shared pages properly - Clock calculation fixes for MMP3 - Clock fixes for OMAP as well" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (42 commits) MAINTAINERS: Add myself as the co-maintainer for Actions Semi platforms ARM: dts: imx7: Fix Toradex Colibri iMX7S 256MB NAND flash support ARM: dts: imx6sll-evk: Remove incorrect power supply assignment ARM: dts: imx6sl-evk: Remove incorrect power supply assignment ARM: dts: imx6sx-sdb: Remove incorrect power supply assignment ARM: dts: imx6qdl-sabresd: Remove incorrect power supply assignment ARM: dts: imx6q-icore-mipi: Use 1.5 version of i.Core MX6DL ARM: omap2plus: select RESET_CONTROLLER ARM: davinci: select CONFIG_RESET_CONTROLLER ARM: dts: aspeed: rainier: Fix fan fault and presence ARM: dts: aspeed: rainier: Remove duplicate i2c busses ARM: dts: aspeed: tacoma: Remove duplicate flash nodes ARM: dts: aspeed: tacoma: Remove duplicate i2c busses ARM: dts: aspeed: tacoma: Fix fsi master node ARM: dts: aspeed-g6: Fix FSI master location ARM: dts: mmp3: Fix the TWSI ranges clk: mmp2: Fix the order of timer mux parents ARM: mmp: do not divide the clock rate arm64: dts: rockchip: Fix IR on Beelink A1 optee: Fix multi page dynamic shm pool alloc ...

2020-01-14parisc: fix map_pages() to actually populate upper directoryMike Rapoport1-1/+1
The commit d96885e277b5 ("parisc: use pgtable-nopXd instead of 4level-fixup") converted PA-RISC to use folded page tables, but it missed the conversion of pgd_populate() to pud_populate() in maps_pages() function. This caused the upper page table directory to remain empty and the system would crash as a result. Using pud_populate() that actually populates the page table instead of dummy pgd_populate() fixes the issue.

2020-01-11Merge tag 'clone3-tls-v5.5-rc6' of ↵Linus Torvalds17-32/+35
git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux Pull thread fixes from Christian Brauner: "This contains a series of patches to fix CLONE_SETTLS when used with clone3(). The clone3() syscall passes the tls argument through struct clone_args instead of a register. This means, all architectures that do not implement copy_thread_tls() but still support CLONE_SETTLS via copy_thread() expecting the tls to be located in a register argument based on clone() are currently unfortunately broken. Their tls value will be garbage. The patch series fixes this on all architectures that currently define __ARCH_WANT_SYS_CLONE3. It also adds a compile-time check to ensure that any architecture that enables clone3() in the future is forced to also implement copy_thread_tls(). My ultimate goal is to get rid of the copy_thread()/copy_thread_tls() split and just have copy_thread_tls() at some point in the not too distant future (Maybe even renaming copy_thread_tls() back to simply copy_thread() once the old function is ripped from all arches). This is dependent now on all arches supporting clone3(). While all relevant arches do that now there are still four missing: ia64, m68k, sh and sparc. They have the system call reserved, but not implemented. Once they all implement clone3() we can get rid of ARCH_WANT_SYS_CLONE3 and HAVE_COPY_THREAD_TLS. This series also includes a minor fix for the arm64 uapi headers which caused __NR_clone3 to be missing from the exported user headers. Unfortunately the series came in a little late especially given that it touches a range of architectures. Due to the holidays not all arch maintainers responded in time probably due to their backlog. Will and Arnd have thankfully acked the arm specific changes. Given that the changes are straightforward and rather minimal combined with the fact the that clone3() with CLONE_SETTLS is broken I decided to send them post rc3 nonetheless" * tag 'clone3-tls-v5.5-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: um: Implement copy_thread_tls clone3: ensure copy_thread_tls is implemented xtensa: Implement copy_thread_tls riscv: Implement copy_thread_tls parisc: Implement copy_thread_tls arm: Implement copy_thread_tls arm64: Implement copy_thread_tls arm64: Move __ARCH_WANT_SYS_CLONE3 definition to uapi headers

2020-01-06arm64: Revert support for execute-only user mappingsCatalin Marinas3-11/+6
The ARMv8 64-bit architecture supports execute-only user permissions by clearing the PTE_USER and PTE_UXN bits, practically making it a mostly privileged mapping but from which user running at EL0 can still execute. The downside, however, is that the kernel at EL1 inadvertently reading such mapping would not trip over the PAN (privileged access never) protection. Revert the relevant bits from commit cab15ce604e5 ("arm64: Introduce execute-only page access permissions") so that PROT_EXEC implies PROT_READ (and therefore PTE_USER) until the architecture gains proper support for execute-only user mappings.

Introduce and use remove_pfn_range_from_zone(() for that.
