+Subject: [PATCH] Fix Pointer#initialize using NUM2LL instead of NUM2ULL
+
+If the high bit of the address was set this would raise RangeError
+(bignum too big to convert into long long). This is not uncommon on
+platforms that use the high bits of pointers for purposes such as
+pointer authentication
+
+This also now matches Pointer#address which uses ULL2NUM.

+Subject: [PATCH 1/2] Rename sparc64-linux -> sparcv9-linux
+
+In https://github.com/ffi/ffi/pull/575, 64-bit sparc was changed to also
+use sparcv9 as the platform name, but the types.conf directory was never
+renamed.  This breaks only on Ruby 3.0 and later due to the fileutils
+change to use keyword arguments in
+https://github.com/ruby/fileutils/commit/482de6d397742526d1111576e2791f9b7051e3c0
