2020-12-22kasan: rename KASAN_SHADOW_* to KASAN_GRANULE_*Andrey Konovalov
This is a preparatory commit for the upcoming addition of a new hardware tag-based (MTE-based) KASAN mode. The new mode won't be using shadow memory, but will still use the concept of memory granules. Each memory granule maps to a single metadata entry: 8 bytes per one shadow byte for generic mode, 16 bytes per one shadow byte for software tag-based mode, and 16 bytes per one allocation tag for hardware tag-based mode. Rename KASAN_SHADOW_SCALE_SIZE to KASAN_GRANULE_SIZE, and KASAN_SHADOW_MASK to KASAN_GRANULE_MASK. Also use MASK when used as a mask, otherwise use SIZE. No functional changes.

2020-12-21Merge tag 'clk-for-linus' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "The core framework got some nice improvements this time around. We gained the ability to get struct clk pointers from a struct clk_hw so that clk providers can consume the clks they provide, if they need to do something like that. This has been a long missing part of the clk provider API that will help us move away from exposing a struct clk pointer in the struct clk_hw. Tracepoints are added for the clk_set_rate() "range" functions, similar to the tracepoints we already have for clk_set_rate() and we added a column to debugfs to help developers understand the hardware enable state of clks in case firmware or bootloader state is different than what is expected. Overall the core changes are mostly improving the clk driver writing experience. At the driver level, we have the usual collection of driver updates and new drivers for new SoCs. This time around the Qualcomm folks introduced a good handful of clk drivers for various parts of three or four SoCs. The SiFive folks added a new clk driver for their FU740 SoCs, coming in second on the diffstat and then Atmel AT91 and Amlogic SoCs had lots of work done after that for various new features. One last thing to note in the driver area is that the i.MX driver has gained a new binding to support SCU clks after being on the list for many months. It uses a two cell binding which is sort of rare in clk DT bindings. Beyond that we have the usual set of driver fixes and tweaks that come from more testing and finding out that some configuration was wrong or that a driver could support being built as a module. Summary: Core: - Add some trace points for clk_set_rate() "range" functions - Add hardware enable information to clk_summary debugfs - Replace clk-provider.h with of_clk.h when possible - Add devm variant of clk_notifier_register() - Add clk_hw_get_clk() to generate a struct clk from a struct clk_hw New Drivers: - Bindings for Canaan K210 SoC clks - Support for SiFive FU740 PRCI - Camera clks on Qualcomm SC7180 SoCs - GCC and RPMh clks on Qualcomm SDX55 SoCs - RPMh clks on Qualcomm SM8350 SoCs - LPASS clks on Qualcomm SM8250 SoCs Updates: - DVFS support for AT91 clk driver - Update git repo branch for Renesas clock drivers - Add camera (CSI) and video-in (VIN) clocks on Renesas R-Car V3U - Add RPC (QSPI/HyperFLASH) clocks on Renesas RZ/G2M, RZ/G2N, and RZ/G2E - Stop using __raw_*() I/O accessors in Renesas clk drivers - One more conversion of DT bindings to json-schema - Make i.MX clk-gate2 driver more flexible - New two cell binding for i.MX SCU clks - Drop of_match_ptr() in i.MX8 clk drivers - Add arch dependencies for Rockchip clk drivers - Fix i2s on Rockchip rk3066 - Add MIPI DSI clks on Amlogic axg and g12 SoCs - Support modular builds of Amlogic clk drivers - Fix an Amlogic Video PLL clock dependency - Samsung Kconfig dependencies updates for better compile test coverage - Refactoring of the Samsung PLL clocks driver - Small Tegra driver cleanups - Minor fixes to Ingenic and VC5 clk drivers - Cleanup patches to remove unused variables and plug memory leaks" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (134 commits) dt-binding: clock: Document canaan,k210-clk bindings dt-bindings: Add Canaan vendor prefix clk: vc5: Use "idt,voltage-microvolt" instead of "idt,voltage-microvolts" clk: ingenic: Fix divider calculation with div tables clk: sunxi-ng: Make sure divider tables have sentinel clk: s2mps11: Fix a resource leak in error handling paths in the probe function clk: mvebu: a3700: fix the XTAL MODE pin to MPP1_9 clk: si5351: Wait for bit clear after PLL reset clk: at91: sam9x60: remove atmel,osc-bypass support clk: at91: sama7g5: register cpu clock clk: at91: clk-master: re-factor master clock clk: at91: sama7g5: do not allow cpu pll to go higher than 1GHz clk: at91: sama7g5: decrease lower limit for MCK0 rate clk: at91: sama7g5: remove mck0 from parent list of other clocks clk: at91: clk-sam9x60-pll: allow runtime changes for pll clk: at91: sama7g5: add 5th divisor for mck0 layout and characteristics clk: at91: clk-master: add 5th divisor for mck master clk: at91: sama7g5: allow SYS and CPU PLLs to be exported and referenced in DT dt-bindings: clock: at91: add sama7g5 pll defines clk: at91: sama7g5: fix compilation error ...

2020-12-21kbuild: doc: clarify the difference between extra-y and always-yMasahiro Yamada
The difference between extra-y and always-y is obscure. Basically, Kbuild builds targets listed in extra-y and always-y in visited Makefiles without relying on any dependency. The difference is that extra-y is used to list the targets needed for vmlinux whereas always-y is used to list the targets that must be always built irrespective of final targets. Kbuild skips extra-y when it is building only modules (i.e. 'make modules'). This is the long-standing behavior since extra-y was introduced in 2003, and it is explained in that commit log [1]. For clarification, this is the extra-y vs always-y table: extra-y always-y 'make' y y 'make vmlinux' y y 'make modules' n y Kbuild skips extra-y also when building external modules since obviously it never builds vmlinux. Unfortunately, extra-y is wrongly used in many places of upstream code, and even in external modules. Using extra-y in external module Makefiles is wrong. What you should use is probably always-y or 'targets'. The current documentation for extra-y is misleading. I rewrote it, and moved it to the section 3.7. always-y is not documented anywhere. I added.

The if_changed macro is currently explained in the section "Commands useful for building a boot image", but the use of if_changed is not limited to the boot image. It is often used together with custom rules. Let's split it as a separate section, and insert it after the "Custom Rules" section.

2020-12-21kbuild: doc: merge 'Special Rules' and 'Custom kbuild commands' sectionsMasahiro Yamada
The two sections "3.10 Special Rules" and "7.8 Custom kbuild commands" are related because you must understand both of them when you write custom rules. Actually I do not understand the policy about what to go into "3 The kbuild files" and what into "7 Architecture Makefile". This commit reworks the custom rule explanation as follows: - Merged "7.8 Custom kbuild commands" into "3.10 Special Rules". - Reword "Special Rules" to "Custom Rules" for consistency. - Update the example for kecho because the blackfin Makefile does not exist any more. - Replace the example for cmd_<command> with a simpler one.

2020-12-21kbuild: doc: replace arch/$(ARCH)/ with arch/$(SRCARCH)/Masahiro Yamada
Precisely speaking, the arch directory is specified by $(SRCARCH), not $(ARCH). In old days, $(ARCH) actually matched to the arch directory because 32-bit and 64-bit were supported as separate architectures. Most architectures (except arm/arm64) were unified like follows: arch/i386, arch/x86_64 -> arch/x86 arch/sh, arch/sh64 -> arch/sh arch/sparc, arch/sparc64 -> arch/sparc To not break the user interface, commit 6752ed90da03 ("Kbuild: allow arch/xxx to use a different source path") introduced SRCARCH to point to the arch directory, still allowing to pass in the former ARCH=i386 or ARCH=x86_64.

Some RTCs, e.g. the pcf2127, can be used as a hardware watchdog. But if the reset pin is not actually wired up, the driver exposes a watchdog device that doesn't actually work. Provide a standard binding that can be used to indicate that a given RTC can perform a reset of the machine, similar to wakeup-source.

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: "The major update to this release is that there's a new arch config option called CONFIG_HAVE_DYNAMIC_FTRACE_WITH_ARGS. Currently, only x86_64 enables it. All the ftrace callbacks now take a struct ftrace_regs instead of a struct pt_regs. If the architecture has HAVE_DYNAMIC_FTRACE_WITH_ARGS enabled, then the ftrace_regs will have enough information to read the arguments of the function being traced, as well as access to the stack pointer. This way, if a user (like live kernel patching) only cares about the arguments, then it can avoid using the heavier weight "regs" callback, that puts in enough information in the struct ftrace_regs to simulate a breakpoint exception (needed for kprobes). A new config option that audits the timestamps of the ftrace ring buffer at most every event recorded. Ftrace recursion protection has been cleaned up to move the protection to the callback itself (this saves on an extra function call for those callbacks). Perf now handles its own RCU protection and does not depend on ftrace to do it for it (saving on that extra function call). New debug option to add "recursed_functions" file to tracefs that lists all the places that triggered the recursion protection of the function tracer. This will show where things need to be fixed as recursion slows down the function tracer. The eval enum mapping updates done at boot up are now offloaded to a work queue, as it caused a noticeable pause on slow embedded boards. Various clean ups and last minute fixes" * tag 'trace-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (33 commits) tracing: Offload eval map updates to a work queue Revert: "ring-buffer: Remove HAVE_64BIT_ALIGNED_ACCESS" ring-buffer: Add rb_check_bpage in __rb_allocate_pages ring-buffer: Fix two typos in comments tracing: Drop unneeded assignment in ring_buffer_resize() tracing: Disable ftrace selftests when any tracer is running seq_buf: Avoid type mismatch for seq_buf_init ring-buffer: Fix a typo in function description ring-buffer: Remove obsolete rb_event_is_commit() ring-buffer: Add test to validate the time stamp deltas ftrace/documentation: Fix RST C code blocks tracing: Clean up after filter logic rewriting tracing: Remove the useless value assignment in test_create_synth_event() livepatch: Use the default ftrace_ops instead of REGS when ARGS is available ftrace/x86: Allow for arguments to be passed in to ftrace_regs by default ftrace: Have the callbacks receive a struct ftrace_regs instead of pt_regs MAINTAINERS: assign ./fs/tracefs to TRACING tracing: Fix some typos in comments ftrace: Remove unused varible 'ret' ring-buffer: Add recording of ring buffer recursion into recursed_functions ...
