Numbers from the script: include/asm-i386 240 files include/asm-x86_64 169 files ------------------------------ 409 files include/asm-x86 389 files arch/i386 335 files arch/x86_64 141 files ------------------------------ 476 files arch/x86 484 files The increase here is due to migration helper files which only include the (_32.x or the _64.x) variant. Makefile helpers 9 files Kconfig helpers 1 file Source helpers 4 files ------------------------------ 14 files Summary: vanilla 22657 files vanilla->x86 22649 files ------------------------------ include/x86 has 125 _32 and 125 _64 files arch/x86 has 55 _32 and 55 _64 files 25 files were auto-merged Looking at include/asm-x86/*_[32/64].h there are offhand ~ 50 of the 125 which differ only minimal (white space damage, comment changes, ...), where the unification is a no brainer. tglx
