[GIT PULL] parisc updates for v3.10

[Helge Deller]

Linus,

please pull the parisc architecture updates for v3.10 from:

  git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-for-3.10


Main fixes and updates in this patch series are:
 - we faced kernel stack corruptions because of multiple delivery of interrupts
 - added kernel stack overflow checks
 - added possibility to use dedicated stacks for irq processing
 - initial support for page sizes > 4k
 - more information in /proc/interrupts (e.g. TLB flushes and number of IPI calls)
 - documented how the parisc gateway page works
 - and of course quite some other smaller cleanups and fixes.

Thanks,
Helge

Does this mean that the parisc tree I have in linux-next
(git://git.kernel.org/pub/scm/linux/kernel/git/jejb/parisc-2.6.git#for-next)
is defunct?

Not sure. It will be either James or me who will send pull requests...
Of course we will agree who of us will do that and from which tree.

So, would it hurt if you add a second parisc tree for linux-next?
I've just created a "for-next" branch in my git repository: 
git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git#for-next

I have no problem having both trees in linux-next (as long as you don't
tread on each other's toes and cause merge problem too often :-)).

I have added your tree from today (noting that it is empty).  I have set
you and the parisc mailing list as contacts.

Thanks for adding your subsystem tree as a participant of linux-next.  As
you may know, this is not a judgment of your code.  The purpose of
linux-next is for integration testing and to lower the impact of
conflicts between subsystems in the next merge window. 

You will need to ensure that the patches/commits in your tree/series have
been:
     * submitted under GPL v2 (or later) and include the Contributor's
	Signed-off-by,
     * posted to the relevant mailing list,
     * reviewed by you (or another maintainer of your subsystem tree),
     * successfully unit tested, and 
     * destined for the current or next Linux merge window.

Basically, this should be just what you would send to Linus (or ask him
to fetch).  It is allowed to be rebased if you deem it necessary.

Legal Stuff:
By participating in linux-next, your subsystem tree contributions are
public and will be included in the linux-next trees.  You may be sent
e-mail messages indicating errors or other issues when the
patches/commits from your subsystem tree are merged and tested in
linux-next.  These messages may also be cross-posted to the linux-next
mailing list, the linux-kernel mailing list, etc.  The linux-next tree
project and IBM (my employer) make no warranties regarding the linux-next
project, the testing procedures, the results, the e-mails, etc.  If you
don't agree to these ground rules, let me know and I'll remove your tree
from participation in linux-next.

[GIT PULL] parisc updates for v3.10

[Helge Deller]

Hi Linus,

please pull the parisc-for-3.10 branch of 

  git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-for-3.10

to get the latest bug and build fixes for the parisc architecture.

Thanks,
Helge

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

The second round of parisc updates for 3.10 includes build fixes and
enhancements to utilize irq stacks, fixes SMP races when updating PTE
and TLB entries by proper locking and makes the search for the correct
cross compiler more robust on Debian and Gentoo.

----------------------------------------------------------------
Helge Deller (2):
      parisc: implement irq stacks - part 2 (v2)

Needs CC:stable as without this building 3.9.x is not possible in some 
configurations.

Possibly also this as it's a bugfix, but Dave is the one who may be judge how 
"clear" it is.

The same is probably true for these from the first round of updates:

John David Anglin (2):
      parisc: use long branch in fork_like macro
Mike Frysinger (1):
      parisc: fix NATIVE set up in build

While I _really_ appreciate the speedup that recently happened to the parisc 
development recently I would also appreciate if we can can finally get the 
bugfix parts of that into stable kernels so we have the non-development tree 
buildable and working without the need to backport all those stuff by hand.

[GIT PULL] parisc updates for v3.10

[Helge Deller]

Hi Linus,

Please pull the latest parisc architecture fixes from:

  git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-3.10

It contains a kernel segfault fix when reading /proc/kpageflags or /proc/kpagecount,
two fixes for the serial port and PCI graphic card support on C8000 workstations
and a fix to use unshadowed registers for flushing D- and I-caches.


This patchset touches parisc-specific source files only.

Thanks,
Helge
