2020-05-21ARM: dts: pxa*: Fix up encoding of the /rtc interrupts propertyLubomir Rintel
This way the device tree validator learns that each cell of the property constitutes a separate item. Otherwise it gets unnecessairly upset: pxa168-aspenite.dt.yaml: rtc@d4010000: interrupts: [[5, 6]] is too short pxa910-dkb.dt.yaml: rtc@d4010000: interrupts: [[5, 6]] is too short Signed-off-by: Lubomir Rintel <lkundrak@v3.sk> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2020-05-21x86/tsc: Add tsc_early_khz command line parameterKrzysztof Piecuch
Changing base clock frequency directly impacts TSC Hz but not CPUID.16h value. An overclocked CPU supporting CPUID.16h and with partial CPUID.15h support will set TSC KHZ according to "best guess" given by CPUID.16h relying on tsc_refine_calibration_work to give better numbers later. tsc_refine_calibration_work will refuse to do its work when the outcome is off the early TSC KHZ value by more than 1% which is certain to happen on an overclocked system. Fix this by adding a tsc_early_khz command line parameter that makes the kernel skip early TSC calibration and use the given value instead. This allows the user to provide the expected TSC frequency that is closer to reality than the one reported by the hardware, enabling tsc_refine_calibration_work to do meaningful error checking. [ tglx: Made the variable __initdata as it's only used on init and removed the error checking in the argument parser because kstrto*() only stores to the variable if the string is valid ] Signed-off-by: Krzysztof Piecuch <piecuch@protonmail.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Link: https://lkml.kernel.org/r/O2CpIOrqLZHgNRkfjRpz_LGqnc1ix_seNIiOCvHY4RHoulOVRo6kMXKuLOfBVTi0SMMevg6Go1uZ_cL9fLYtYdTRNH78ChaFaZyG3VAyYz8=@protonmail.com

For SC7180 it adds GPU support, defines the modem remoteproc, adds the IPA network accelerator, Coresight and ETM support, adds cpuidle low power states and updates the CPUs' compatible. For SM8250 it adds regulators from the PM8150, PM8150L and PM8009 and adds voltage corners, it defines the nodes for UFS PHY and controller and finally corrects a typo in the PDC node to make SPMI functional. For MSM8916 I2C1 and I2C5 are defined, a node for the CCI camera control interface bus is added and Coresight is disabled by default to match some product configurations. The Samsung A3U gained display support and Samsung A5U gained touchscreen support. MSM8996 now property describes the power supply chain for the GPU, the CCI camera control interface bus is added and the DB820c has the regulators of the secondary PMIC defined. For QCS404 USB PHYs and controllers are defined and wired up for the EVB. SDM630/SDM660 platform support is added and the Xiaomi Redmi Note 7 defined.

2020-05-21RISC-V: gp_in_global needs register keywordPalmer Dabbelt
The Intel kernel build robot recently pointed out that I missed the register keyword on this one when I refactored the code to remove local register variables (which aren't supported by LLVM). GCC's manual indicates that global register variables must have the register keyword, As far as I can tell lacking the register keyword causes GCC to ignore the __asm__ and treat this as a regular variable, but I'm not sure how that didn't show up as some sort of failure.

2020-05-21exec: Remove recursion from search_binary_handlerEric W. Biederman
Recursion in kernel code is generally a bad idea as it can overflow the kernel stack. Recursion in exec also hides that the code is looping and that the loop changes bprm->file. Instead of recursing in search_binary_handler have the methods that would recurse set bprm->interpreter and return 0. Modify exec_binprm to loop when bprm->interpreter is set. Consolidate all of the reassignments of bprm->file in that loop to make it clear what is going on. The structure of the new loop in exec_binprm is that all errors return immediately, while successful completion (ret == 0 && !bprm->interpreter) just breaks out of the loop and runs what exec_bprm has always run upon successful completion. Fail if the an interpreter is being call after execfd has been set. The code has never properly handled an interpreter being called with execfd being set and with reassignments of bprm->file and the assignment of bprm->executable in generic code it has finally become possible to test and fail when if this problematic condition happens. With the reassignments of bprm->file and the assignment of bprm->executable moved into the generic code add a test to see if bprm->executable is being reassigned. In search_binary_handler remove the test for !bprm->file. With all reassignments of bprm->file moved to exec_binprm bprm->file can never be NULL in search_binary_handler.

2020-05-22powerpc/64s: Disable STRICT_KERNEL_RWXMichael Ellerman
Several strange crashes have been eventually traced back to STRICT_KERNEL_RWX and its interaction with code patching. Various paths in our ftrace, kprobes and other patching code need to be hardened against patching failures, otherwise we can end up running with partially/incorrectly patched ftrace paths, kprobes or jump labels, which can then cause strange crashes. Although fixes for those are in development, they're not -rc material. There also seem to be problems with the underlying strict RWX logic, which needs further debugging. So for now disable STRICT_KERNEL_RWX on 64-bit to prevent people from enabling the option and tripping over the bugs.

2020-05-21arm64: vdso: Fix CFI directives in sigreturn trampolineWill Deacon
Daniel reports that the .cfi_startproc is misplaced for the sigreturn trampoline, which causes LLVM's unwinder to misbehave: | I run into this with LLVM’s unwinder. | This combination was always broken. This prompted Dave to question our use of CFI directives more generally, and I ended up going down a rabbit hole trying to figure out how this very poorly documented stuff gets used. Move the CFI directives so that the "mysterious NOP" is included in the .cfi_{start,end}proc block and add a bunch of comments so that I can save myself another headache in future.

2020-05-21arm64: vdso: Don't prefix sigreturn trampoline with a BTI C instructionWill Deacon
For better or worse, GDB relies on the exact instruction sequence in the VDSO sigreturn trampoline in order to unwind from signals correctly. Commit c91db232da48 ("arm64: vdso: Convert to modern assembler annotations") unfortunately added a BTI C instruction to the start of __kernel_rt_sigreturn, which breaks this check. Thankfully, it's also not required, since the trampoline is called from a RET instruction when returning from the signal handler Remove the unnecessary BTI C instruction from __kernel_rt_sigreturn, and do the same for the 32-bit VDSO as well for good measure.
