+Subject: Port ctypes and system libffi patches for arm64/macOS 10.15+ to Python 3.7.12
+
+This ports the following ctypes and libffi pyenv patches for Python
+2.7.18 to Python 3.7.12:
+
+* `0004-Use-system-libffi-for-Mac-OS-10.15-and-up.patch`
+* `0005-ctypes-use-the-correct-ABI-for-variadic-functions.patch`
+* `0006-ctypes-probe-libffi-for-ffi_closure_alloc-and-ffi_pr.patch`
+
+These patches enable use of system libffi (fixing a broken `ctypes`
+module on arm64 targets) and enable calling variadic functions on arm64.
+They've been combined from patches port from Homebrew to pyenv by Takumi
+Sueda, updated to work on the Python 3.7.12 codebase.
+
+The Homebrew patches are themselves backports of changes in Python 3.9
+and 3.10. That patch can be found at:
+
+https://github.com/Homebrew/formula-patches/blob/master/python/3.8.7.patch
