linux-next: Tree for July 1

linux-next: Tree for July 1

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 10174 bytes --]

Hi all,

Changes since 20110630:

New tree: akpm (a subset of mmotm - Andrew can now start eating again :-))

The powerpc tree gained another build failure so I used the version from
next-20110630.

The security-testing tree lost its bad merge.

The kvm tree lost its conflict.

The akpm tree gained two build failures for which I revertd a commit and
applied a patch.

----------------------------------------------------------------------------

I have created today's linux-next tree at
git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
(patches at http://www.kernel.org/pub/linux/kernel/v2.6/next/ ).  If you
are tracking the linux-next tree using git, you should not use "git pull"
to do so as that will try to merge the new linux-next release with the
old one.  You should use "git fetch" as mentioned in the FAQ on the wiki
(see below).

You can see which trees have been included by looking in the Next/Trees
file in the source.  There are also quilt-import.log and merge.log files
in the Next directory.  Between each merge, the tree was built with
a ppc64_defconfig for powerpc and an allmodconfig for x86_64. After the
final fixups (if any), it is also built with powerpc allnoconfig (32 and
64 bit), ppc44x_defconfig and allyesconfig (minus
CONFIG_PROFILE_ALL_BRANCHES - this fails its final link) and i386, sparc
and sparc64 defconfig. These builds also have
CONFIG_ENABLE_WARN_DEPRECATED, CONFIG_ENABLE_MUST_CHECK and
CONFIG_DEBUG_INFO disabled when necessary.

Below is a summary of the state of the merge.

We are up to 195 trees (counting Linus' and 28 trees of patches pending
for Linus' tree), more are welcome (even if they are currently empty).
Thanks to those who have contributed, and to those who haven't, please do.

Status of my local build tests will be at
http://kisskb.ellerman.id.au/linux-next .  If maintainers want to give
advice about cross compilers/configs that work, we are always open to add
more builds.

Thanks to Randy Dunlap for doing many randconfig builds.

There is a wiki covering stuff to do with linux-next at
http://linux.f-seidel.de/linux-next/pmwiki/ .  Thanks to Frank Seidel.

on x86_64 when CONFIG_ISA_DMA_API is not enabled.

Since that driver handles both ISA and PCI devices,
and the PCI parts are conditional, I guess that the ISA parts also
need to be made conditional.

[PATCH -next] staging: fix comedi NI labpc driver build when ISA_DMA_API is not enabled

I'd rather that someone who has a strong interest in comedi (or NI labpc)
do that, but here it is anyway.

From: Randy Dunlap <randy.dunlap@oracle.com>

Fix ni_labpc.c to build when CONFIG_ISA_DMA_API is not enabled.

This is a driver that supports both ISA and PCI devices.
It now builds when for PCI-only support or for both
ISA and PCI device support.
(It does not support ISA-only without PCI.)
