  "message": "Make the \"word-at-a-time\" helper functions more commonly usable\n\nI have a new optimized x86 \"strncpy_from_user()\" that will use these\nsame helper functions for all the same reasons the name lookup code uses\nthem.  This is preparation for that.\n\nThis moves them into an architecture-specific header file.  It\u0027s\narchitecture-specific for two reasons:\n\n - some of the functions are likely to want architecture-specific\n   implementations.  Even if the current code happens to be \"generic\" in\n   the sense that it should work on any little-endian machine, it\u0027s\n   likely that the \"multiply by a big constant and shift\" implementation\n   is less than optimal for an architecture that has a guaranteed fast\n   bit count instruction, for example.\n\n - I expect that if architectures like sparc want to start playing\n   around with this, we\u0027ll need to abstract out a few more details (in\n   particular the actual unaligned accesses).  So we\u0027re likely to have\n   more architecture-specific stuff if non-x86 architectures start using\n   this.\n\n   (and if it turns out that non-x86 architectures don\u0027t start using\n   this, then having it in an architecture-specific header is still the\n   right thing to do, of course)\n\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
