- arch/riscv/include/asm/processor.h: "requries" → "is required"
- arch/riscv/include/asm/thread_info.h: "returing" → "returning"
- arch/riscv/kernel/acpi.c: "compliancy" → "compliance"
- arch/riscv/kernel/ftrace.c: "therefor" → "therefore"
- arch/riscv/kernel/head.S: "intruction" → "instruction"
- arch/riscv/kernel/mcount-dyn.S: "localtion → "location"
- arch/riscv/kernel/module-sections.c: "maxinum" → "maximum"
- arch/riscv/kernel/probes/kprobes.c: "reenabled" → "re-enabled"
- arch/riscv/kernel/probes/uprobes.c: "probbed" → "probed"
- arch/riscv/kernel/soc.c: "extremly" → "extremely"
- arch/riscv/kernel/suspend.c: "incosistent" → "inconsistent"
- arch/riscv/kvm/tlb.c: "cahce" → "cache"
- arch/riscv/kvm/vcpu_pmu.c: "indicies" → "indices"
- arch/riscv/lib/csum.c: "implmentations" → "implementations"
