I can't easily provide a transcript for the vendor tree. Basically, I
removed all the files in a working copy, leaving the directories and
.svn stuff alone. Next, I copied the new version (from a git tree) and
ran a script that deletes missing files and adds new files. I checked
in the result at tagged it 2.6.14. I've done this many times without
any problems. However in this case it turned out that what I thought
was 2.6.14 was actually 2.6.14 plus some badly broken stuff. So, the
"backed out this change" step just repeated the above, copying a
different git view. I deleted the old 2.6.14 tag and created a new
2.6.14 tag. The problem is that the 2.6.14+ version had a huge number
of changes and a number of files that were deleted. When I checked in
the proper 2.6.14 code, some of the ancestry was lost.
So next I wanted to merge my 2.6.13 based devel tree with the new 2.6.14 tree:
# check out clean working copy of the trunk
$ svn co svn+ssh://.../trunk/np/linux
$ svn status -u
... no error ...
# merge previous linux tag with new linux tag from vendor tree
$ svn merge svn+ssh://.../vendor/linux-mips/2.6.13 \
... 645 deletes, 733 adds, 4227 updates, 1 'Skipped missing target' ...
... NOTE: The merge doesn't finish, it fails with:
svn: URL 'svn+ssh://.../vendor/linux-mips/2.6.14/drivers/acpi/ospm'
doesn't match existing
URL 'svn+ssh://.../trunk/np/linux/drivers/acpi/ospm' in 'drivers/acpi/ospm'
# at this point the working copy is broken:
$ svn status -u
svn: Working copy path 'include/asm-ppc64/hw_irq.h' does not exist in repository
$ svn status include/asm-ppc64/hw_irq.h
R + include/asm-ppc64/hw_irq.h

One interesting thing the merge had a number of lines like:
So the file was deleted (2.6.14+) and then added back (2.6.14). This
seems to be the root of the problem.
I tried doing the merge with '--ignore-ancestry', but this didn't work
either, it failed with:
Skipped missing target: 'kernel/fork.c'
... many more skipped missing targets ...
Skipped missing target: 'include/asm-ia64/socket.h'
Skipped missing target: 'include/asm-ia64'
svn: Working copy 'include' is missing or not locked
