[PATCH 0/7 v2] Refactor shared code in {i386,amd64}-linux-nat.c

[Gary Benson <gbenson@redhat.com>]

Hi all,

This series is an updated version of the series I posted this morning.
Mark Kettenis rightly pointed out that x86_linux_read_description was
a mess of #ifdef spaghetti so I have rewritten it.

Patch 2 has changed because that's where the x86_linux_read_description
merge is.  Patch 6 has changed because that's where the code is pulled
from {i386,amd64}-linux-nat.c into x86-linux-nat.c.  The remaining
patches are the same.

I've inlined the original description of the series below.

Is this ok to commit?

Thanks,
Gary

This series refactors the shared code in {i386,amd64}-linux-nat.c into
the new files x86-linux-nat.[ch] and i386-linux-nat.h.  The first five
patches remove spurious changes between the files so that the code to
be shared is identical:

  1/7 - Rename identical functions
  2/7 - Merge {i386,amd64}_linux_read_description
  3/7 - Merge ps_get_thread_area
  4/7 - Pull out common parts of _initialize_{i386,amd64}_linux_nat
  5/7 - Comment and whitespace changes

The sixth patch moves the shared code into the new files and does all
the makefile and build system updates:

  6/7 - Move duplicated code into new files

The seventh patch tidies the blocks of #include directives at the
tops of {i386,amd64}-linux-nat.c:

  7/7 - Tidy #include lists

This final patch is not strictly necessary for the series, but it
makes things tidier.
