2.6.16-rc2-mm1 patches don't apply

[Paul Jackson <pj@sgi.com>]

Andrew,

The patchset for 2.6.16-rc2-mm1 seems borked.

It contains patches in linus.patch that are already in 2.6.16-rc2.

Hence, this *-mm patch set cannot be applied on top of 2.6.16-rc2.


For example, consider the following.

Linus tagged v2.6.16-rc2 at this revision (hg log format):

	changeset:   19933:6a79f5a2de38
	tag:         v2.6.16-rc2
	user:        Linus Torvalds <torvalds@g5.osdl.org>
	date:        Fri Feb  3 14:03:08 2006 +0800
	summary:     Linux v2.6.16-rc2

The following patch is included earlier in v2.6.16-rc2:

	changeset:   19738:81ca7cda8d38
	user:        Lucas Correia Villa Real <lucasvr@gobolinux.org>
	date:        Wed Feb  1 21:24:23 2006 +0000
	summary:     [ARM] 3284/1: S3C2400 - adds support to GPIO

It affects a few files, including the following change, obtained using
the command hg diff -r 19737 -r 19738 arch/arm/mach-s3c2410/Makefile:

The linus.patch in the broken out patch set:

Looks familiar, huh?

That's the same change, in both linus.patch of 2.6.16-rc2-mm1, and
in what Linus marked as 2.6.16-rc2.

I think that there are some more, perhaps dozens, of such
duplicated patches.  See my earlier lkml post Message-Id:
<20060208131708.f81b025e.pj@sgi.com> in response to Andrew's
2.6.16-rc2-mm1 announcement, for circumstantial evidence of more such
damage to this patch set.
