• c6ebaf6bd   unaligned-memory-access.txt: standardize document format ... Browse Code »

  Each text file under Documentation follows a different
  format. Some doesn't even have titles!

  Change its representation to follow the adopted standard,
  using ReST markups for it to be parseable by Sphinx:
  - promote document title one level;
  - use markups for authorship and put it at the beginning;
  - mark literal blocks;
  - adjust identation.

• 36f671be1   Documentation/unaligned-memory-access.txt: fix incorrect comparison operator ... Browse Code »

  In the actual implementation ether_addr_equal function tests for equality to 0
  when returning. It seems in commit 0d74c4 it is somehow overlooked to change
  this operator to reflect the actual function.

• 0d74c42f7   ether_addr_equal: Optimize implementation, remove unused compare_ether_addr ... Browse Code »

  Add a new check for CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS to reduce
  the number of or's used in the ether_addr_equal comparison to very
  slightly improve function performance.

  Simplify the ether_addr_equal_64bits implementation.
  Integrate and remove the zap_last_2bytes helper as it's now
  used only once.

  Remove the now unused compare_ether_addr function.

  Update the unaligned-memory-access documentation to remove the
  compare_ether_addr description and show how unaligned accesses
  could occur with ether_addr_equal.

• 58340a07c   introduce HAVE_EFFICIENT_UNALIGNED_ACCESS Kconfig symbol ... Browse Code »

  In many cases, especially in networking, it can be beneficial to know at
  compile time whether the architecture can do unaligned accesses efficiently.
  This patch introduces a new Kconfig symbol

  HAVE_EFFICIENT_UNALIGNED_ACCESS

  for that purpose and adds it to the powerpc and x86 architectures. Also add
  some documentation about alignment and networking, and especially one intended
  use of this symbol.

  Here's a document I wrote after figuring out what unaligned memory access
  is all about. I've tried to cover the information I was looking for when
  trying to learn about this, without producing a hopelessly detailed/complex
  spew. I hope it is useful to others.
