Merge branch 'at91'

Joachim Eastwood says;

====================
This patch series prepares the old at91_ether driver for code sharing
with the macb driver. The hardware is similar except for DMA TX/RX, so
its not quite clear if it is practical to support both in one
driver. But stuff like MDIO and statistics should be possible to
share.

Patch 1 adds some register defines and bits that is only found on
RM9200.

Patch 2-4 uses the register defines and access functions from the macb
header. These can be squashed if it cause too much churn.

Patch 5 merges the private at91_ether struct with the private macb
struct. This makes it easier to later share code with the macb. The
private macb struct becomes quite large, but most at91_ether specific
members are removed in later patches.

Patch 8 make macb compile when we select at91_ether. Is this approach
okey?

Patch 9 makes use of MDIO code from macb. This rips out the private
phy handling code in at91_ether. One thing that is lost is the
interrupt support for phy. But this should easy to add to macb which
will then benefit both drivers.

Patch 10 makes use of the macb_set_rx_mode from macb.

Patch 11-12 makes at91_ether share the rx dma struct members from
macb. Patch also moves the rx buffer allocation into netdev open and
dealloc into netdev close.

Last patch remove the now unused rm9200 emac header from include/mach.

netlink: use kfree_rcu() in netlink_release()

On some suspend/resume operations involving wimax device, we have
noticed some intermittent memory corruptions in netlink code.

Stéphane Marchesin tracked this corruption in netlink_update_listeners()
and suggested a patch.

It appears netlink_release() should use kfree_rcu() instead of kfree()
for the listeners structure as it may be used by other cpus using RCU
protection.

netlink_release() must set to NULL the listeners pointer when
it is about to be freed.

Also have to protect netlink_update_listeners() and
netlink_has_listeners() if listeners is NULL.

Add a nl_deref_protected() lockdep helper to properly document which
locks protects us.

  (1) Import a patch from Catalin Marinas to extend the generic-y in
      Kbuild facility to uapi directories.

  (2) Make arch/tile's ucontext.h file use (1) and remove the header-y
      line from the kernel internal side of things.

  (3) Remove some now-empty conditional bits from include/linux/Kbuild.
      The contents got moved to the UAPI side of things along with new
      conditionals.

  (4) Deal with now-empty files:

     (a) Empty Kbuild files under include/ get removed.

     (b) Empty Kbuild files under arch/ get comments to hold them as
         they are likely to end up with generic-y or genhdr-y lines.
         Deleting them appears to work if we want to go that route.

     (c) Put a comment into uapi/asm-generic/kvm_para.h to prevent the
         patch program from deleting that, and made the arches with
         empty kvm_para.h uapi files use that instead of having their
         own files.

     (d) Put comments into four other empty uapi/ headers to prevent the
         patch program from deleting them.

  A question: Is this the right way to deal with the now-empty Kbuild
  files?

  The ones under include/ are unlikely to be used - even for generated
  files, I think - so getting rid of them is probably okay.  Once all
  the bits are in, we can probably remove all the Kbuild files under
  include/ that aren't also under include/uapi/.

  The ones under arch/ are more of an issue because of the potential for
  generic-y and genhdr-y."

12 years agoUAPI: Remove empty non-UAPI Kbuild files
David Howells [Wed, 17 Oct 2012 11:31:15 +0000 (12:31 +0100)]
UAPI: Remove empty non-UAPI Kbuild files

Remove non-UAPI Kbuild files that have become empty as a result of UAPI
disintegration.  They used to have only header-y lines in them and those have
now moved to the Kbuild files in the corresponding uapi/ directories.

Possibly these should not be removed but rather have a comment inserted to say
they are intentionally left blank.  This would make it easier to add generated
header lines in future without having to restore the infrastructure.

Note that at this point not all the UAPI disintegration parts have been merged,
so it is likely that more empty Kbuild files will turn up.

It is probably necessary to make the files non-empty to prevent the patch
program from automatically deleting them when it reduces them to nothing.

UAPI: Make uapi/linux/irqnr.h non-empty

uapi/linux/irqnr.h was emitted by the UAPI disintegration script as an empty
file because the parent linux/irqnr.h had no UAPI stuff in it, despite being
marked with "header-y".

Unfortunately, the patch program deletes the empty file when applying a kernel
patch.

It's not clear why this file is part of the UAPI at all.  Looking in:

/usr/include/linux/irqnr.h

there's nothing there but a header reinclusion guard and a comment.

So just stick a comment in there as a placeholder.

Without this, if the kernel is fabricated from, say, a tarball and a patch, you
can get this error when building x86_64 or usermode Linux (and probably
others):

mm, mempolicy: fix printing stack contents in numa_maps

When reading /proc/pid/numa_maps, it's possible to return the contents of
the stack where the mempolicy string should be printed if the policy gets
freed from beneath us.

This happens because mpol_to_str() may return an error the
stack-allocated buffer is then printed without ever being stored.

There are two possible error conditions in mpol_to_str():

 - if the buffer allocated is insufficient for the string to be stored,
   and

 - if the mempolicy has an invalid mode.

The first error condition is not triggered in any of the callers to
mpol_to_str(): at least 50 bytes is always allocated on the stack and this
is sufficient for the string to be written.  A future patch should convert
this into BUILD_BUG_ON() since we know the maximum strlen possible, but
that's not -rc material.

The second error condition is possible if a race occurs in dropping a
reference to a task's mempolicy causing it to be freed during the read().
The slab poison value is then used for the mode and mpol_to_str() returns
-EINVAL.

This race is only possible because get_vma_policy() believes that
mm->mmap_sem protects task->mempolicy, which isn't true.  The exit path
does not hold mm->mmap_sem when dropping the reference or setting
task->mempolicy to NULL: it uses task_lock(task) instead.

Thus, it's required for the caller of a task mempolicy to hold
task_lock(task) while grabbing the mempolicy and reading it.  Callers with

12 years agosparc64: Fix bit twiddling in sparc_pmu_enable_event().
David S. Miller [Tue, 16 Oct 2012 20:05:25 +0000 (13:05 -0700)]
sparc64: Fix bit twiddling in sparc_pmu_enable_event().

There was a serious disconnect in the logic happening in
sparc_pmu_disable_event() vs. sparc_pmu_enable_event().

Event disable is implemented by programming a NOP event into the PCR.

However, event enable was not reversing this operation.  Instead, it
was setting the User/Priv/Hypervisor trace enable bits.

That's not sparc_pmu_enable_event()'s job, that's what
sparc_pmu_enable() and sparc_pmu_disable() do .

The intent of sparc_pmu_enable_event() is clear, since it first clear
out the event type encoding field.  So fix this by OR'ing in the event
encoding rather than the trace enable bits.

12 years agoqeth: fix deadlock between recovery and bonding driver
Stefan Raspl [Mon, 15 Oct 2012 19:21:18 +0000 (19:21 +0000)]
qeth: fix deadlock between recovery and bonding driver

The recovery thread, when failing, tears down the respective interface. To do
so, it needs to obtain the rtnl lock first, as the interface configuration is
changed.
If another process tries to modify an interface setting at the same time, that
process can obtain the rtnl lock first, but the respective callback in the qeth
driver will block until recovery has completed - which cannot happen since the
calling process already obtained it.
In one particular case, the bonding driver acquired the rtnl lock to modify the
card's MAC address, while the recovery failed at the same time due to the card
being removed. Hence qeth_l2_set_mac_address (implicitly holding the rtnl lock)
was waiting on qeth_l2_recover, which deadlocked when waiting on the rtnl lock.
This patch uses rtnl_trylock instead of rtnl_lock in the recovery thread. If the
lock cannot be obtained, the interface will be left up, but the card state
remains in CARD_STATE_RECOVER, which will prevent any further activities on the
card.
