Merge branch 'for-next/kernel-mode-neon' into for-next/core
* for-next/kernel-mode-neon:
arm64: neon/efi: Make EFI fpsimd save/restore variables static
arm64: neon: Forbid when irqs are disabled
arm64: neon: Export kernel_neon_busy to loadable modules
arm64: neon: Temporarily add a kernel_mode_begin_partial() definition
arm64: neon: Remove support for nested or hardirq kernel-mode NEON
arm64: neon: Allow EFI runtime services to use FPSIMD in irq context
arm64: fpsimd: Consistently use __this_cpu_ ops where appropriate
arm64: neon: Add missing header guard in <asm/neon.h>
arm64: neon: replace generic definition of may_use_simd()
