Repeatedly enabling and disabling the display currently can lead to a state

Now that ipu_dc_disable_channel correctly waits for the channel to finish,
we can reorder the enable/disable order to first stop the DC and DI and
only then disable the IDMAC. Enabling is done the other way around: IDMAC
first, then DC, then DI.
This avoids an issue where sometimes the channel

Two additions really. The first patch adds some needed debugging info.
The second one includes an optimization suggested by Oleg. I preferred
waiting until 3.15 for these, giving the code a chance to settle a bit.
Thanks!

mm: fix CONFIG_DEBUG_VM_RB description
This appears to be a copy/paste error. Update the description
to reflect extra rbtree debug and checks for the config option
instead of duplicating CONFIG_DEBUG_VM.

For single threaded workloads, we can avoid flushing

the whole function a lot faster, requiring only a single
atomic read for the mm_users.

In smp with multi cpus, when enter into kdump kernel with only 1 cpu,
a warning message is printed out:

In this case kdump kernel use the same ACPI tables as 1st kernel,
means lapic information is got from MADT. The acpi_id related

I was trying to cook a not too invasive patch.
Changing ip_local_out() means changing dst_output() / nf_hook() and
hundred of call sites.
Unless
We got no-reply almost a week, so we can assume can put the code into
asm/io.h as static inline function.
I will/should send patch v2 for it.
Thanks.

I was testing v3.15-rc1 in my qemu-system-arm environment and noticed a

After looking around in the kernel and not finding such a message, I
realized this was actually a
