I've not reviewed all of this, but a couple of observations.
1) We don't use the ARM64 in gcc. Please change them to AArch64.
2) The documentation for TARGET_D_CRITSEC_SIZE should probably be
explicit that the size is in bytes (it's implied by the examples). Some
hooks/macros in GCC return a size in bits, so it's best to be explicit.
I can't see any other obvious issues with the ARM and AArch64 code.
