Using the same hash function in compression on both x86 and ARM On Intel the instruction used is CRC-32C (Castagnoli), which uses a different polynomial than 'traditional' crc32 deployed in zlib. Fortunately ARM has instructions for both polynomials, so this patch will ensure that compressed content using Chromium's zlib will match i.e. checksums should be the same.
