      scripts/checkpatch.pl: reset rpt_cleaners warnings · b0781216
      由 Mike Frysinger 提交于 
      If you run checkpatch against multiple patches, and one of them has a
whitespace issue which can be helped via a script (rpt_cleaners), you will
see the same NOTE over and over for all subsequent patches.  It makes it
seem like those patches also have whitespace problems when in reality,
there's only one or two bad apples.

So reset rpt_cleaners back to 0 after we've issued the note so that it
only shows up near the patch with the actual problems.

      kstrto*: converting strings to integers done (hopefully) right · 33ee3b2e
      由 Alexey Dobriyan 提交于 
      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.

      semaphore: Remove mutex emulation · 4882720b
      由 Thomas Gleixner 提交于 
      Semaphores used as mutexes have been deprecated for years. Now that
all users are either converted to real semaphores or to mutexes remove
the cruft.
