2021-09-14docs: block: fix discard_max_bytes referencesStephen Kitt1-4/+5
When discard_max_hw_bytes was introduced, in commit 0034af036554 ("block: make /sys/block/<dev>/queue/discard_max_bytes writeable"), the discard_max_bytes documentation section was renamed to discard_max_hw_bytes, but the references it contains to discard_max_bytes weren't updated. This patch refers to discard_max_hw_bytes instead. It also reflows the paragraph so that sentences end lines.

2021-09-14dt-bindings: serial: uartlite: Add properties for synthesis-time parametersSean Anderson1-0/+37
The uartlite device is a "soft" device. Many parameters, such as baud rate, data bits, and the presence of a parity bit are configured before synthesis and may not be changed (or discovered) at runtime. However, we must know what these settings are in order to properly calculate the uart timeout (and to inform the user about the actual baud of the uart). These properties are present for out-of-tree bindings generated by Xilinx's tools. However, they are also (mostly) present in in-tree bindings. I chose current-speed over xlnx,baudrate primarily because it seemed to be used by more existing bindings. Although these properties are marked as "required", note that only current-speed is required by the driver itself. Hopefully, this will allow for an easier transition.

2021-09-13rcu: Fix undefined Kconfig macrosZhouyi Zhou1-37/+32
Invoking scripts/checkkconfigsymbols.py in the Linux-kernel source tree located the following issues: 1. TREE_PREEMPT_RCU Referencing files: arch/sh/configs/sdk7786_defconfig It should now be CONFIG_PREEMPT_RCU. Except that the CONFIG_PREEMPT=y in that same file implies CONFIG_PREEMPT_RCU=y. Therefore, delete the CONFIG_TREE_PREEMPT_RCU=y line. The reason is as follows: In kernel/rcu/Kconfig, we have config PREEMPT_RCU bool default y if PREEMPTION https://www.kernel.org/doc/Documentation/kbuild/kconfig-language.txt says, "The default value is only assigned to the config symbol if no other value was set by the user (via the input prompt above)." there is no prompt in config PREEMPT_RCU entry, so we are guaranteed to get CONFIG_PREEMPT_RCU=y when CONFIG_PREEMPT is present. 2. RCU_CPU_STALL_INFO Referencing files: arch/xtensa/configs/nommu_kc705_defconfig The old Kconfig option RCU_CPU_STALL_INFO was removed by commit 75c27f119b64 ("rcu: Remove CONFIG_RCU_CPU_STALL_INFO"), and the kernel now acts as if this Kconfig option was unconditionally enabled. 3. RCU_NOCB_CPU_ALL Referencing files: Documentation/RCU/Design/Memory-Ordering/Tree-RCU-Memory-Ordering.rst This is an old snapshot of the code. I update this from the real rcu_prepare_for_idle() function in kernel/rcu/tree_plugin.h. This change was tested by invoking "make htmldocs". 4. RCU_TORTURE_TESTS Referencing files: kernel/rcu/rcutorture.c Forward-progress checking conflicts with CPU-stall testing, so we should complain at "modprobe rcutorture" when both are enabled.

2021-09-13Merge branch 'gcc-min-version-5.1' (make gcc-5.1 the minimum version)Linus Torvalds4-4/+4
Merge patch series from Nick Desaulniers to update the minimum gcc version to 5.1. This is some of the left-overs from the merge window that I didn't want to deal with yesterday, so it comes in after -rc1 but was sent before. Gcc-4.9 support has been an annoyance for some time, and with -Werror I had the choice of applying a fairly big patch from Kees Cook to remove a fair number of initializer warnings (still leaving some), or this patch series from Nick that just removes the source of the problem. The initializer cleanups might still be worth it regardless, but honestly, I preferred just tackling the problem with gcc-4.9 head-on. We've been more aggressiuve about no longer having to care about compilers that were released a long time ago, and I think it's been a good thing. I added a couple of patches on top to sort out a few left-overs now that we no longer support gcc-4.x. As noted by Arnd, as a result of this minimum compiler version upgrade we can probably change our use of '--std=gnu89' to '--std=gnu11', and finally start using local loop declarations etc. But this series does _not_ yet do that.

2021-09-13Documentation: raise minimum supported version of GCC to 5.1Nick Desaulniers1-1/+1
commit fad7cd3310db ("nbd: add the check to prevent overflow in __nbd_ioctl()") raised an issue from the fallback helpers added in commit f0907827a8a9 ("compiler.h: enable builtin overflow checkers and add fallback code") Specifically, the helpers for checking whether the results of a multiplication overflowed (__unsigned_mul_overflow, __signed_add_overflow) use the division operator when !COMPILER_HAS_GENERIC_BUILTIN_OVERFLOW. This is problematic for 64b operands on 32b hosts. Also, because the macro is type agnostic, it is very difficult to write a similarly type generic macro that dispatches to one of: * div64_s64 * div64_u64 * div_s64 * div_u64 Raising the minimum supported versions allows us to remove all of the fallback helpers for !COMPILER_HAS_GENERIC_BUILTIN_OVERFLOW, instead dispatching the compiler builtins. arm64 has already raised the minimum supported GCC version to 5.1, do this for all targets now. See the link below for the previous discussion.

2021-09-13Merge series "ARM: dts: Last round of DT schema fixes" from Maxime Ripard <maxime@cerno.tech>:Mark Brown7-40/+173
Hi, Here's another round of schema warnings fixes for the Allwinner platform. There's a fair share of new schemas in there since the schema tools now warn when a compatible is not documented in a schema. We don't have any warning anymore if we use the OPP binding Rob submitted, and since that means we have all our devices properly validated I don't expect more fixes now, aside from the usual bunch of regressions.

Document the compatible values for the remaining R-Car Gen3e SoCs: R-Car H3e (R8A779M0), M3e (R8A779M2), M3Ne (R8A779M4), M3Ne-2G (R8A779M5), E3e (R8A779M6), D3e (R8A779M7), and H3Ne (R8A779M8). These are different gradings of R-Car Gen3 SoCs. All R-Car Gen3e on-SoC devices are identical to the devices on the corresponding R-Car Gen3 SoCs, and thus just use the compatible values for the latter. The root compatible properties do gain an additional value, to sort out integration issues if they ever arise. Document the use of these SoCs on the Salvator-XS, ULCB (with and without Kingfisher extension), Ebisu, and Draak development boards.
