Commit c014d164 ("MIPS: Add platform callback before initializing the L2 cache") added a platform_early_l2_init function in order to allow platforms to probe for the CM before L2 initialisation is performed, so that CM GCRs are available to mips_sc_probe. That commit actually fails to do anything useful, since it checks mips_cm_revision to determine whether it should call mips_cm_probe but the result of mips_cm_revision will always be 0 until mips_cm_probe has been called. Thus the "early" mips_cm_probe call never occurs. Fix this & drop the useless weak platform_early_l2_init function by simply calling mips_cm_probe from setup_arch. For platforms that don't select CONFIG_MIPS_CM this will be a no-op, and for those that do it removes the requirement for them to call mips_cm_probe manually (although doing so isn't harmful for now).

In the regular MIPS instruction set RDHWR is encoded with the SPECIAL3 (011111) major opcode. Therefore it cannot trigger the CpU (Coprocessor Unusable) exception, and certainly not for coprocessor 0, as the opcode does not overlap with any of the older ISA reservations, i.e. LWC0 (110000), SWC0 (111000), LDC0 (110100) or SDC0 (111100). The closest match might be SDC3 (111111), possibly causing a CpU #3 exception, however our code does not handle it anyway. A quick check with a MIPS I and a MIPS III processor: CPU0 revision is: 00000220 (R3000) CPU0 revision is: 00000440 (R4400SC) indeed indicates that the RI (Reserved Instruction) exception is triggered. It's only LL and SC that require emulation in the CpU #0 exception handler as they reuse the LWC0 and SWC0 opcodes respectively. In the microMIPS instruction set RDHWR is mandatory and triggering the RI exception is required on unimplemented or disabled register accesses. Therefore emulating the microMIPS instruction in the CpU #0 exception handler is not required either. Signed-off-by:

The FPU should not be left enabled after a task context switch. This isn't usually a problem as the FPU enable bit is updated before returning to userland, however it can potentially mask kernel bugs, and in fact KVM assumes it won't happen and won't clear the FPU enable bit before returning to the guest, which allows the guest to use stale FPU context. Interrupts and exceptions save and restore most bits of the CP0 Status register which contains the FPU enable bit (CU1). When the kernel needs to enable or disable the FPU (for example due to attempted FPU use by userland, or the scheduler being invoked) both the actual Status register and the saved value in the userland context are updated. However this doesn't work correctly with full kernel preemption enabled, since the FPU enable bit can be cleared from within an interrupt when the scheduler is invoked, and only the userland context is updated, not the interrupt context. For example: 1) Enter kernel with FPU already enabled, TIF_USEDFPU=1, Status.CU1=1 saved. 2) Take a timer interrupt while in kernel mode, Status.CU1=1 saved. 3) Timer interrupt invokes scheduler to preempt the task, which clears TIF_USEDFPU, disables the FPU in Status register (Status.CU1=0), and the value stored in user context from step (1), but not the interrupt context from step (2). 4) When the process is scheduled back in again Status.CU1=0. 5) The interrupt context from step (2) is restored, which sets Status.CU1=1. So from user context point of view, preemption has re-enabled FPU! 6) If the scheduler is invoked again (via preemption or voluntarily) before returning to userland, TIF_USEDFPU=0 so the FPU is not disabled before the task context switch. 7) The next task resumes from the context switch with FPU enabled! The restoring of the Status register on return from interrupt/exception is already selective about which bits to restore, leaving the interrupt mask bits alone so enabling/disabling of CPU interrupt lines can persist. Extend this to also leave both the CU1 bit (FPU enable) and the FR bit (which specifies the FPU mode and gets changed with CU1). This prevents a stale Status value being restored in step (5) above and persisting through subsequent context switches. Also switch to the use of definitions from asm/mipsregs.h while we're at it. Since this change also affects the restoration of Status register on the path back to userland, it increases the sensitivity of the kernel to the problem of the FPU being left enabled, allowing it to propagate to userland, therefore a warning is also added to lose_fpu_inatomic() to point out any future reoccurances before they do any damage.

start_thread() (called for execve(2)) clears the TIF_USEDFPU flag without atomically disabling the FPU. With a preemptive kernel, an unfortunately timed preemption after this could result in another task (or KVM guest) being scheduled in with the FPU still enabled, since lose_fpu_inatomic() only turns it off if TIF_USEDFPU is set. Use lose_fpu(0) instead of the separate FPU / MSA management, which should do the right thing (drop FPU properly and atomically without saving state) and will be more future proof. Signed-off-by:

Since commit 4c21b8fd ("MIPS: seccomp: Handle indirect system calls (o32)"), syscall_get_arguments() attempts to handle o32 indirect syscall arguments by incrementing both the start argument number and the number of arguments to fetch. However only the start argument number needs to be incremented. The number of arguments does not change, they're just shifted up by one, and in fact the output array is provided by the caller and is likely only n entries long, so reading more arguments overflows the output buffer. In the case of seccomp, this results in it fetching 7 arguments starting at the 2nd one, which overflows the unsigned long args[6] in populate_seccomp_data(). This clobbers the $s0 register from syscall_trace_enter() which __seccomp_phase1_filter() saved onto the stack, into which syscall_trace_enter() had placed its syscall number argument. This caused Chromium to crash. Credit goes to Milko for tracking it down as far as $s0 being clobbered. Fixes: 4c21b8fd ("MIPS: seccomp: Handle indirect system calls (o32)") Reported-by:

Pull power management and ACPI fixes from Rafael Wysocki: "These are: cpuidle fixes (including one fix for a recent regression), cpufreq fixes (including fixes for two issues introduced during the 4.2 cycle), generic power domains framework fixes (two locking fixes and one cleanup), one locking fix in the ACPI-based PCI hotplug framework (ACPIPHP), removal of one ACPI backlight blacklist entry that isn't necessary any more and a PM Kconfig cleanup. Specifics: - Fix a recent cpuidle core regression that broke suspend-to-idle on all systems where cpuidle drivers don't provide ->enter_freeze callbacks for any states (Sudeep Holla). - Drop an unnecessary symbol definition from the cpuidle core code handling coupled CPU cores (Anders Roxell). - Fix a race condition related to governor initialization and removal in the cpufreq core (Viresh Kumar). - Clean up the cpufreq core to use list_is_last() for checking if the given policy object is the last element of a list instead of open coding that in a clumsy way (Gautham R Shenoy). - Fix compiler warnings in the pxa2xx and cpufreq-dt cpufreq drivers (Arnd Bergmann). - Fix two locking issues and clean up a comment in the generic power domains framework (Ulf Hansson, Marek Szyprowski, Moritz Fischer). - Fix the error code path of one function in the ACPI-based PCI hotplug framework (ACPIPHP) that forgets to release a lock acquired previously (Insu Yun). - Drop the ACPI backlight blacklist entry for Dell Inspiron 5737 that is not necessary any more (Hans de Goede). - Clean up the top-level PM Kconfig to stop requiring APM emulation to depend on PM which in fact isn't necessary (Arnd Bergmann)" * tag 'pm+acpi-4.5-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: cpufreq: cpufreq-dt: avoid uninitialized variable warnings: cpufreq: pxa2xx: fix pxa_cpufreq_change_voltage prototype PM: APM_EMULATION does not depend on PM cpufreq: Use list_is_last() to check last entry of the policy list cpufreq: Fix NULL reference crash while accessing policy->governor_data cpuidle: coupled: remove unused define cpuidle_coupled_lock PM / Domains: Fix typo in comment PM / Domains: Fix potential deadlock while adding/removing subdomains ACPI / PCI / hotplug: unlock in error path in acpiphp_enable_slot() ACPI: Revert "ACPI / video: Add Dell Inspiron 5737 to the blacklist" cpuidle: fix fallback mechanism for suspend to idle in absence of enter_freeze PM / domains: fix lockdep issue for all subdomains
