[GIT PULL] new files form asm-generic

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Linus,

This is a series of patches that adds a mostly-complete set of generic
header files in the include/asm-generic hierarchy.

Please pull
git://git.kernel.org:/pub/scm/linux/kernel/git/arnd/asm-generic.git for-linus

None of these patches should impact currently executed code in
any way, but there are four goals here:

1 Give architecture maintainers a set of generic header files that they
  can work with to reduce code duplication. I currently have three series
  of patches doing this, one for each of x86, power and microblaze. The
  plan is to get those integrated through the arch maintainers in the
  2.6.32 merge window. The amount of code added here will be more than
  made up if two architectures drop their duplicate files later.

2 Allow the merging of the score architecture. Based on my feedback, this
  has migrated to using most of the header files from this series, so
  it has become a dependency. I'd like to get my code in as early as
  possible in this merge window to give them a chance to rebase on the
  mainline tree for merging.

3 Give the microblaze architecture the chance to fix their ABI. That
  code is still carrying some legacy warts in its user space ABI, and
  Michal Simek agreed to convert to the asm-generic versions of the
  exported headers once they get in, changing the microblaze ABI one
  last time.

4 Serve as an example to new architecture maintainers on how they should
  implement their files. In many cases, they can simply use the generic
  version, in others they can use them as a base for their own optimized
  versions.


The patches have been worked on by myself, with significant testing and
improvements from Remis. The logic to get there was roughly for each
file:

- if less than two thirds of the architectures implement it, don't
  touch it. (e.g. vdso.h)

- if all architectures are fundamentally different, don't touch it.
  (e.g. ptrace.h) There are fewer of these than I expected.

- if most architectures agree on a sane approach, use that one.
  (e.g. current.h)

- if an incomplete header file exists in asm-generic, rename that
  and provide a new file according to the other rules (e.g. page.h,
  mman.h).

- if there are common variants that are only slightly different,
  create a generalized variant that an architecture can choose its
  way by potentially overriding the defaults (e.g. ioctls.h, types.h),
  make the default option either the most sane or the most common one.

- if all architectures are different without a good reason, choose
  the sanest combination of contents so the future ones are all the
  same (e.g. unistd.h, stat.h)

- if an architecture only needs it to support a feature (e.g. SMP,
  PCI, MMU), add a file for the case where that feature is not present,
  (e.g. page.h, vga.h). Simple architectures can now fall back on this
  file, more sophisticated ones need their own code.
