This reverts commit de95ab53645a2f0015e0f68ee723f18dce2b8b51.
Markus Trippelsdorf reported that this commit broke 'perf top':
> I just see a gray screen with no text at all. Sometimes the
> following error messages are printed:
>
> *** Error in `perf': invalid fastbin entry (free): 0x00000000029b18c0
> ***
> *** Error in `perf': malloc(): memory corruption (fast): 0x0000000000ee0b10 ***
While this code is fixable, the commit itself fails on several levels:
- it should have been a separate helper function
- why the heck does it do strchr() twice
- it casts a const char * over into char *
- sloppy style
- it's not even a regression fix!
So lets revert it and re-try the patch in v3.13.

There is currently serialization network namespaces exiting and
network devices exiting as the final part of netdev_run_todo does not
happen under the rtnl_lock. This is compounded by the fact that the
only list of devices unregistering in netdev_run_todo is local to the
netdev_run_todo.
This lack of serialization in extreme cases results in network devices
unregistering in netdev_run_todo after the loopback device of their
network namespace has been freed (making dst_ifdown unsafe), and after
the their network namespace has exited (making the NETDEV_UNREGISTER,
and NETDEV_UNREGISTER_FINAL callbacks unsafe).
Add the missing serialization by a per network namespace count of how
many network devices are unregistering and having a wait queue that is
woken up whenever the count is decreased. The count and wait queue
allow default_device_exit_batch to wait until all of the unregistration
activity for a network namespace has finished before proceeding to
unregister the loopback device and then allowing the network namespace
to exit.
Only a single global wait queue is used because there is a single global
lock, and there is a single waiter, per network namespace wait queues
would be a waste of resources.
The per network namespace count of unregistering devices gives a
progress guarantee because the number of network devices unregistering
in an exiting network namespace must ultimately drop to zero (assuming
network device unregistration completes).
The basic logic remains the same as in v1. This patch is now half
comment and half rtnl_lock_unregistering an expanded version of
wait_event performs no extra work in the common case where no network
devices are unregistering when we get to default_device_exit_batch.

from Viresh Kumar.
2) If intel_pstate has been loaded already, it doesn't make sense to
do anything in acpi_cpufreq_init() and moreover doing something in
there in that case may be harmful, so make that function return
immediately if another cpufreq driver is already present. From
Yinghai Lu.
3) The ACPI IPMI driver sometimes attempts to acquire a mutex from
interrupt context, which can be avoided by replacing that mutex
with a spinlock. From Lv Zheng.
4) A NULL pointer may be dereferenced by the exynos5440 cpufreq

Ben Herrenschmidt found that commit 928bea964827 ("PCI: Delay enabling
bridges until they're needed") breaks PCI in some powerpc environments.
The reason is that the PCIe port driver will call pci_enable_device() on
the bridge, so the device is enabled, but skips pci_set_master because
pcie_port_auto and no acpi on powerpc.
Because of that, pci_enable_bridge() later on (called as a result of the
child device driver doing pci_enable_device) will see the bridge as
already enabled and will not call pci_set_master() on it.
Fixed by add checking in pci_enable_bridge, and call pci_set_master
if driver skip that.
That will make the code more robot and wade off problem for missing
pci_set_master in drivers.

git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 lockref enablement from Heiko Carstens:
"Enabling the new lockless lockref variant on s390 would have been
trivial until Tony Luck added a cpu_relax() call into the
CMPXCHG_LOOP(), with commit d472d9d98b46 ("lockref: Relax in cmpxchg
loop")
As already mentioned cpu_relax() is very expensive on s390 since it
yields() the current virtual cpu. So we are talking of several
thousand cycles. Considering this enabling the lockless lockref
variant would contradict the intention of the new semantics. And also
some quick measurements show performance regressions of 50% and more.
Simply removing the cpu_relax() call again seems also not very
desireable since Waiman Long reported that for some workloads the call
improved performance by 5%."

Commit 117a0c5fc9c2d06045bd217385b2b39ea426b5a6 ("sparc: kernel: using
strlcpy() instead of strcpy()") added a bug to ldom_reboot in

- strcpy(full_boot_str + strlen("boot "), boot_command);
+ strlcpy(full_boot_str + strlen("boot "), boot_command,
+ sizeof(full_boot_str + strlen("boot ")));
That last sizeof() expression evaluates to sizeof(size_t) which is
not what was intended.
Also even the corrected:
sizeof(full_boot_str) + strlen("boot ")
is not right as the destination buffer length is just plain
"sizeof(full_boot_str)" and that's what the final argument
should be.

If context switching happens during executing fpsimd_flush_thread(),
stale value in FPSIMD registers will be saved into current thread's
fpsimd_state by fpsimd_thread_switch(). That may cause invalid
initialization state for the new process, so disable preemption
when executing fpsimd_flush_thread().
