      kstrto*: converting strings to integers done (hopefully) right · 33ee3b2e
      Alexey Dobriyan authored
      1. simple_strto*() do not contain overflow checks and crufty,
         libc way to indicate failure.
      2. strict_strto*() also do not have overflow checks but the name and
         comments pretend they do.
      3. Both families have only "long long" and "long" variants,
         but users want strtou8()
      4. Both "simple" and "strict" prefixes are wrong:
         Simple doesn't exactly say what's so simple, strict should not exist
         because conversion should be strict by default.
      
      The solution is to use "k" prefix and add convertors for more types.
      Enter
      	kstrtoull()
      	kstrtoll()
      	kstrtoul()
      	kstrtol()
      	kstrtouint()
      	kstrtoint()
      
      	kstrtou64()
      	kstrtos64()
      	kstrtou32()
      	kstrtos32()
      	kstrtou16()
      	kstrtos16()
      	kstrtou8()
      	kstrtos8()
      
      Include runtime testsuite (somewhat incomplete) as well.
      
      strict_strto*() become deprecated, stubbed to kstrto*() and
      eventually will be removed altogether.
      
      Use kstrto*() in code today!
      
      Note: on some archs _kstrtoul() and _kstrtol() are left in tree, even if
            they'll be unused at runtime. This is temporarily solution,
            because I don't want to hardcode list of archs where these
            functions aren't needed. Current solution with sizeof() and
            __alignof__ at least always works.
