2021-11-12tracing/histogram: Fix check for missing operands in an expressionKalesh Singh
If a binary operation is detected while parsing an expression string, the operand strings are deduced by splitting the experssion string at the position of the detected binary operator. Both operand strings are sub-strings (can be empty string) of the expression string but will never be NULL. Currently a NULL check is used for missing operands, fix this by checking for empty strings instead.

2021-11-12tracing/histogram: Do not copy the fixed-size char array field over the ↵Masami Hiramatsu
field size Do not copy the fixed-size char array field of the events over the field size. The histogram treats char array as a string and there are 2 types of char array in the event, fixed-size and dynamic string. The dynamic string (__data_loc) field must be null terminated, but the fixed-size char array field may not be null terminated (not a string, but just a data). In that case, histogram can copy the data after the field. This uses the original field size for fixed-size char array field to restrict the histogram not to access over the original field size.

2021-11-12tools/lib/lockdep: drop liblockdepSasha Levin
TL;DR: While a tool like liblockdep is useful, it probably doesn't belong within the kernel tree. liblockdep attempts to reuse kernel code both directly (by directly building the kernel's lockdep code) as well as indirectly (by using sanitized headers). This makes liblockdep an integral part of the kernel. It also makes liblockdep quite unique: while other userspace code might use sanitized headers, it generally doesn't attempt to use kernel code directly which means that changes on the kernel side of things don't affect (and break) it directly. All our workflows and tooling around liblockdep don't support this uniqueness. Changes that go into the kernel code aren't validated to not break in-tree userspace code. liblockdep ended up being very fragile, breaking over and over, to the point that living in the same tree as the lockdep code lost most of it's value. liblockdep should continue living in an external tree, syncing with the kernel often, in a controllable way.

2021-11-12thermal: int340x: fix build on 32-bit targetsLinus Torvalds
Commit aeb58c860dc5 ("thermal/drivers/int340x: processor_thermal: Suppot 64 bit RFIM responses") started using 'readq()' to read 64-bit status responses from the int340x hardware. That's all fine and good, but on 32-bit targets a 64-bit 'readq()' is ambiguous, since it's no longer an atomic access. Some hardware might require 64-bit accesses, and other hardware might want low word first or high word first. It's quite likely that the driver isn't relevant in a 32-bit environment any more, and there's a patch floating around to just make it depend on X86_64, but let's make it buildable on x86-32 anyway. The driver previously just read the low 32 bits, so the hardware certainly is ok with 32-bit reads, and in a little-endian environment the low word first model is the natural one. So just add the include for the 'io-64-nonatomic-lo-hi.h' version.

2021-11-12net,lsm,selinux: revert the security_sctp_assoc_established() hookPaul Moore
This patch reverts two prior patches, e7310c94024c ("security: implement sctp_assoc_established hook in selinux") and 7c2ef0240e6a ("security: add sctp_assoc_established hook"), which create the security_sctp_assoc_established() LSM hook and provide a SELinux implementation. Unfortunately these two patches were merged without proper review (the Reviewed-by and Tested-by tags from Richard Haines were for previous revisions of these patches that were significantly different) and there are outstanding objections from the SELinux maintainers regarding these patches. Work is currently ongoing to correct the problems identified in the reverted patches, as well as others that have come up during review, but it is unclear at this point in time when that work will be ready for inclusion in the mainline kernel. In the interest of not keeping objectionable code in the kernel for multiple weeks, and potentially a kernel release, we are reverting the two problematic patches.

2021-11-12of/irq: Don't ignore interrupt-controller when interrupt-map failedMarc Zyngier
Since 041284181226 ("of/irq: Allow matching of an interrupt-map local to an interrupt controller"), the irq code favors using an interrupt-map over a interrupt-controller property if both are available, while the earlier behaviour was to ignore the interrupt-map altogether. However, we now end-up with the opposite behaviour, which is to ignore the interrupt-controller property even if the interrupt-map fails to match its input. This new behaviour breaks the AmigaOne X1000 machine, which ships with an extremely "creative" (read: broken) device tree. Fix this by allowing the interrupt-controller property to be selected when interrupt-map fails to match anything.

2021-11-12irqchip/sifive-plic: Fixup EOI failed when maskedGuo Ren
When using "devm_request_threaded_irq(,,,,IRQF_ONESHOT,,)" in a driver, only the first interrupt is handled, and following interrupts are never delivered (initially reported in [1]). That's because the RISC-V PLIC cannot EOI masked interrupts, as explained in the description of Interrupt Completion in the PLIC spec [2]: <quote> The PLIC signals it has completed executing an interrupt handler by writing the interrupt ID it received from the claim to the claim/complete register. The PLIC does not check whether the completion ID is the same as the last claim ID for that target. If the completion ID does not match an interrupt source that *is currently enabled* for the target, the completion is silently ignored. </quote> Re-enable the interrupt before completion if it has been masked during the handling, and remask it afterwards.

2021-11-12ARM: 9156/1: drop cc-option fallbacks for architecture selectionArnd Bergmann
Naresh and Antonio ran into a build failure with latest Debian armhf compilers, with lots of output like tmp/ccY3nOAs.s:2215: Error: selected processor does not support `cpsid i' in ARM mode As it turns out, $(cc-option) fails early here when the FPU is not selected before CPU architecture is selected, as the compiler option check runs before enabling -msoft-float, which causes a problem when testing a target architecture level without an FPU: cc1: error: '-mfloat-abi=hard': selected architecture lacks an FPU Passing e.g. -march=armv6k+fp in place of -march=armv6k would avoid this issue, but the fallback logic is already broken because all supported compilers (gcc-5 and higher) are much more recent than these options, and building with -march=armv5t as a fallback no longer works. The best way forward that I see is to just remove all the checks, which also has the nice side-effect of slightly improving the startup time for 'make'. The -mtune=marvell-f option was apparently never supported by any mainline compiler, and the custom Codesourcery gcc build that did support is now too old to build kernels, so just use -mtune=xscale unconditionally for those. This should be safe to apply on all stable kernels, and will be required in order to keep building them with gcc-11 and higher.

2021-11-12KVM: x86: move guest_pv_has out of user_access sectionPaolo Bonzini
When UBSAN is enabled, the code emitted for the call to guest_pv_has includes a call to __ubsan_handle_load_invalid_value. objtool complains that this call happens with UACCESS enabled; to avoid the warning, pull the calls to user_access_begin into both arms of the "if" statement, after the check for guest_pv_has.

2021-11-11dt-bindings: Remove Netlogic bindingsRob Herring
Support for Netlogic was removed in commit 95b8a5e0111a ("MIPS: Remove NETLOGIC support"). Remove the now unused bindings. The GPIO binding also includes "brcm,vulcan-gpio", but it appears to be unused as well as Broadcom Vulkan became Cavium ThunderX2 which is ACPI based.

2021-11-11clk: versatile: clk-icst: Ensure clock names are uniqueRob Herring
Commit 2d3de197a818 ("ARM: dts: arm: Update ICST clock nodes 'reg' and node names") moved to using generic node names. That results in trying to register multiple clocks with the same name. Fix this by including the unit-address in the clock name.
