Well in the case of x86 the call to memset is expensive as well. In most cases it is 16 cycles plus 1 cycle per 16 bytes if I recall correctly.

Re: [mm PATCH v2 1/6] mm: Use mm_zero_struct_page from SPARC on all 64b architectures

I am worried about this change. I added SPARC optimized mm_zero_struct_page() specifically to SPARC because it has a poor performance with small memset()s, since it uses STBI instructions. However, other architectures might not suffer with small memset()s, and have hardware optimized memset variant
