  commit 4950276672fce5c241857540f8561c440663673d upstream.

  Patch series "kmemcheck: kill kmemcheck", v2.

  As discussed at LSF/MM, kill kmemcheck.

  KASan is a replacement that is able to work without the limitation of
  kmemcheck (single CPU, slow). KASan is already upstream.

  We are also not aware of any users of kmemcheck (or users who don't
  consider KASan as a suitable replacement).

  The only objection was that since KASAN wasn't supported by all GCC
  versions provided by distros at that time we should hold off for 2
  years, and try again.

  Now that 2 years have passed, and all distros provide gcc that supports
  KASAN, kill kmemcheck again for the very same reasons.

  This patch (of 4):

  Remove kmemcheck annotations, and calls to kmemcheck from the kernel.

• 313162d0b   device.h: audit and cleanup users in main include dir ... Browse Code »

  86

  The header includes a lot of stuff, and
  it in turn gets a lot of use just for the basic "struct device"
  which appears so often.

  Clean up the users as follows:

  1) For those headers only needing "struct device" as a pointer
  in fcn args, replace the include with exactly that.

  2) For headers not really using anything from device.h, simply
  delete the include altogether.

  3) For headers relying on getting device.h implicitly before
  being included themselves, now explicitly include device.h

  4) For files in which doing #1 or #2 uncovers an implicit
  dependency on some other header, fix by explicitly adding
  the required header(s).

  Any C files that were implicitly relying on device.h to be
  present have already been dealt with in advance.

  Total removals from #1 and #2: 51. Total additions coming
  from #3: 9. Total other implicit dependencies from #4: 7.

  As of 3.3-rc1, there were 110, so a net removal of 42 gives
  about a 38% reduction in device.h presence in include/*

  The macro to_class_dev() uses the deprecated structure class_device, and
  the c2port_device has no member named class in the definition of the macro
  to_c2port_device.

• 4e17e1db9   Add c2 port support ... Browse Code »

  C2port implements a two wire serial communication protocol (bit
  banging) designed to enable in-system programming, debugging, and
  boundary-scan testing on low pin-count Silicon Labs devices.

  Currently this code supports only flash programming through sysfs
  interface but extensions shoud be easy to add.
