#     crypto: arch/nhpoly1305 - process in explicit 4k chunks
#     
#     Rather than chunking via PAGE_SIZE, this commit changes the arch
#     implementations to chunk in explicit 4k parts, so that calculations on
#     maximum acceptable latency don't suddenly become invalid on platforms
#     where PAGE_SIZE isn't 4k, such as arm64.
#     
#     Fixes: 0f961f9f670e ("crypto: x86/nhpoly1305 - add AVX2 accelerated NHPoly1305")
#     Fixes: 012c82388c03 ("crypto: x86/nhpoly1305 - add SSE2 accelerated NHPoly1305")
#     Fixes: a00fa0c88774 ("crypto: arm64/nhpoly1305 - add NEON-accelerated NHPoly1305")
#     Fixes: 16aae3595a9d ("crypto: arm/nhpoly1305 - add NEON-accelerated NHPoly1305")
