Based on the existing arm64 implementation and also used for csky now. - improve the dma-debug infrastructure, including dynamic allocation of entries (Robin Murphy) - default to providing chaining scatterlist everywhere, with opt-outs for the few architectures (alpha, parisc, most arm32 variants) that can't cope with it - misc sparc32 dma-related cleanups - remove the dma_mark_clean arch hook used by swiotlb on ia64 and replace it with the generic noncoherent infrastructure - fix the return type of dma_set_max_seg_size (Niklas Söderlund) - move the dummy dma ops for not DMA capable devices from arm64 to common code (Robin Murphy) - ensure dma_alloc_coherent returns zeroed memory to avoid kernel data leaks through userspace.

In preparation for directly calling the direct mapping code don't bother having it optionally but always build the code in. This is a minor hardship for some powerpc and arm configs that don't pull it in yet (although they should in a relase ot two), and sparc64 which currently doesn't need it at all, but it will reduce the ifdef mess we'd otherwise need significantly.

Hopefully in the next release we can wire up all 22 of those system calls on all 32-bit architectures, which gives us a baseline version for glibc to start using them. This does not include the clock_adjtime, getrusage/waitid, and getitimer/setitimer system calls. I still plan to have new versions of those as well, but they are not required for correct operation of the C library since they can be emulated using the old 32-bit time_t based system calls. Aside from the system calls, there are also a few cleanups here, removing old kernel internal interfaces that have become unused after all references got removed.

By removing the indirection and always using the RTC_CLASS interface, we can avoid the lossy double conversion between rtc_time and timespec, so we end up supporting the entire range of 'year' values, and clarifying the rtc_set_time callback. I did not change the behavior of sh03_rtc_settimeofday(), which keeps just updating the seconds/minutes by calling set_rtc_mmss(), this could be improved if anyone cares.

The table in include/uapi/asm/unistd.h is also not included here, as Firoz is still working on that one, it will have to wait for the next following merge window, hopefully together with the addition of the 64-bit time_t system calls for the y2038 work that led to the system call table rework" * tag 'asm-generic-4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: sh: generate uapi header and syscall table header files sh: add system call table generation support sh: add __NR_syscalls along with NR_syscalls

To make it easy by keeping a script and which will generate the uapi header and syscall table file. This change will also help to unify the implemen- tation across all architectures. The system call table generation script is added in kernel/syscalls directory which contain the scripts to generate both uapi header file and system call table files. The syscall.tbl will be input for the scripts. syscall.tbl contains the list of available system calls along with system call number and corresponding entry point. Add a new system call in this architecture will be possible by adding new entry in the syscall.tbl file. Adding a new table entry consisting of: - System call number. - ABI. - System call name. - Entry point name. syscallhdr.sh and syscalltbl.sh will generate uapi header unistd_32.h and syscall_table.h files respectively. Both .sh files will parse the content syscall.tbl to generate the header and table files. unistd_32.h will be included by uapi/asm/unistd.h and syscall_table.h is included by kernel/syscall_32.S - the real system call table. Please note, this support is only available for 32-bit kernel, not 64-bit kernel. As I came across the 64-bit kernel is not active for long time. ARM, s390 and x86 architecuture does have similar support. I leverage their implementation to come up with a generic solution.

We have to change the value of NR- _syscalls, if we add or delete a system call. One of the patch in this patch series has a script which will generate a uapi header based on syscall.tbl file. The syscall.tbl file contains the total number of system calls information. So we have two option to update NR_sy- scalls value. 1. Update NR_syscalls in asm/unistd.h manually by count- ing the no.of system calls. No need to update NR_sys- calls until we either add a new system call or delete existing system call. 2. We can keep this feature it above mentioned script, that will count the number of syscalls and keep it in a generated file. In this case we don't need to expli- citly update NR_syscalls in asm/unistd.h file. The 2nd option will be the recommended one. For that, I added the __NR_syscalls macro in uapi/asm/unistd_32/64.h along with NR_syscalls which is moved to asm/unistd.h. The macro __NR_syscalls also added for making the name convention same across all architecture. While __NR_sys- calls isn't strictly part of the uapi, having it as part of the generated header to simplifies the implementation. We also need to enclose this macro with #ifdef __KERNEL__ to avoid side effects. Signed-off-by: Firoz Khan <firoz.khan@linaro.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

There's a few things with dependencies and a few things subsystem maintainers didn't pick up, so I'm taking them thru my tree. The fixes from Johan didn't get into linux-next, but they've been waiting for some time now and they are what's left of what subsystem maintainers didn't pick up. Summary: - Sync dtc with upstream version v1.4.7-14-gc86da84d30e4 - Work to get rid of direct accesses to struct device_node name and type pointers in preparation for removing them. New helpers for parsing DT cpu nodes and conversions to use the helpers. printk conversions to %pOFn for printing DT node names. Most went thru subystem trees, so this is the remainder. - Fixes to DT child node lookups to actually be restricted to child nodes instead of treewide. - Refactoring of dtb targets out of arch code. This makes the support more uniform and enables building all dtbs on c6x, microblaze, and powerpc. - Various DT binding updates for Renesas r8a7744 SoC - Vendor prefixes for Facebook, OLPC - Restructuring of some ARM binding docs moving some peripheral bindings out of board/SoC binding files - New "secure-chosen" binding for secure world settings on ARM - Dual licensing of 2 DT IRQ binding headers" * tag 'devicetree-for-4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (78 commits) ARM: dt: relicense two DT binding IRQ headers power: supply: twl4030-charger: fix OF sibling-node lookup NFC: nfcmrvl_uart: fix OF child-node lookup net: stmmac: dwmac-sun8i: fix OF child-node lookup net: bcmgenet: fix OF child-node lookup drm/msm: fix OF child-node lookup drm/mediatek: fix OF sibling-node lookup of: Add missing exports of node name compare functions dt-bindings: Add OLPC vendor prefix dt-bindings: misc: bk4: Add device tree binding for Liebherr's BK4 SPI bus dt-bindings: thermal: samsung: Add SPDX license identifier dt-bindings: clock: samsung: Add SPDX license identifiers dt-bindings: timer: ostm: Add R7S9210 support dt-bindings: phy: rcar-gen2: Add r8a7744 support dt-bindings: can: rcar_can: Add r8a7744 support dt-bindings: timer: renesas, cmt: Document r8a7744 CMT support dt-bindings: watchdog: renesas-wdt: Document r8a7744 support dt-bindings: thermal: rcar: Add device tree support for r8a7744 Documentation: dt: Add binding for /secure-chosen/stdout-path dt-bindings: arm: zte: Move sysctrl bindings to their own doc ...

| |/ | | | | | | | | | | | | | | | | | | | | Use the for_each_of_cpu_node iterator to iterate over cpu nodes. This has the side effect of defaulting to iterating using "cpu" node names in preference to the deprecated (for FDT) device_type == "cpu".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sys_llseek sytem call is needed on all 32-bit architectures and none of the 64-bit ones, so we can remove the __ARCH_WANT_SYS_LLSEEK guard and simplify the include/asm-generic/unistd.h header further. Since 32-bit tasks can run either natively or in compat mode on 64-bit architectures, we have to check for both !CONFIG_64BIT and CONFIG_COMPAT. There are a few 64-bit architectures that also reference sys_llseek in their 64-bit ABI (e.g. sparc), but I verified that those all select CONFIG_COMPAT, so the #if check is still correct here. It's a bit odd to include it in the syscall table though, as it's the same as sys_lseek() on 64-bit, but with strange calling conventions.

| * | y2038: Remove newstat family from default syscall setArnd Bergmann2018-08-291-0/+1
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have four generations of stat() syscalls: - the oldstat syscalls that are only used on the older architectures - the newstat family that is used on all 64-bit architectures but lacked support for large files on 32-bit architectures. - the stat64 family that is used mostly on 32-bit architectures to replace newstat - statx() to replace all of the above, adding 64-bit timestamps among other things. We already compile stat64 only on those architectures that need it, but newstat is always built, including on those that don't reference it. This adds a new __ARCH_WANT_NEW_STAT symbol along the lines of __ARCH_WANT_OLD_STAT and __ARCH_WANT_STAT64 to control compilation of newstat. All architectures that need it use an explict define, the others now get a little bit smaller, and future architecture (including 64-bit targets) won't ever see it.

| * | regulator: fixed: Convert to use GPIO descriptor onlyLinus Walleij2018-09-171-2/+25
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As we augmented the regulator core to accept a GPIO descriptor instead of a GPIO number, we can augment the fixed GPIO regulator to look up and pass that descriptor directly from device tree or board GPIO descriptor look up tables. Some boards just auto-enumerate their fixed regulator platform devices and I have assumed they get names like "fixed-regulator.0" but it's pretty hard to guess this. I need some testing from board maintainers to be sure. Other boards are straight forward, using just plain "fixed-regulator" (ID -1) or "fixed-regulator.1" hammering down the device ID. It seems the da9055 and da9211 has never got around to actually passing any enable gpio into its platform data (not the in-tree code anyway) so we can just decide to simply pass a descriptor instead. The fixed GPIO-controlled regulator in mach-pxa/ezx.c was confusingly named "*_dummy_supply_device" while it is a very real device backed by a GPIO line. There is nothing dummy about it at all, so I renamed it with the infix *_regulator_* as part of this patch set. Intel MID portions tested by Andy.
