Merge branch 'for-next/fpsimd' into for-next/core

* for-next/fpsimd:
  arm64: cpufeature: Warn if we attempt to read a zero width field
  arm64: cpufeature: Add missing .field_width for GIC system registers
  arm64: signal: nofpsimd: Do not allocate fp/simd context when not available
  arm64: cpufeature: Always specify and use a field width for capabilities
  arm64: Always use individual bits in CPACR floating point enables
  arm64: Define CPACR_EL1_FPEN similarly to other floating point controls
