+Subject: [PATCH] lib/arm/cpu_features: fix build error due to PMULL enabled
+ without NEON
+
+When building for soft float arm32, HAVE_PMULL_INTRIN is being set when
+it shouldn't be, causing a build error:
+
+    #error "NEON intrinsics not available with the soft-float ABI..."
+
+Fix this by making HAVE_PMULL_INTRIN depend on HAVE_NEON_INTRIN, as used
+to be the case, in order to get the 'defined(__ARM_FP)' dependency,
+
+Fixes https://github.com/ebiggers/libdeflate/issues/282
+Fixes: 84c76f6f2cf5 ("lib/arm: make crc32 code work with MSVC")
