Now that irq sum accounting for /proc/stat's "intr" line works again we
have the oddity that the sum field (first field) contains only the sum
of the second (external irqs) and third field (I/O interrupts).
The reason for that is that these two fields are already sums of all other
fields. So if we would sum up everything we would count every interrupt
twice.
This is broken since the split interrupt accounting was merged two years
ago: 052ff461c8 "[S390] irq: have detailed
statistics for interrupt types".
To fix this remove the split interrupt fields from /proc/stat's "intr"
line again and only have them in /proc/interrupts.
This restores the old behaviour, seems to be the only sane fix and mimics
a behaviour from other architectures where /proc/interrupts also contains
more than /proc/stat's "intr" line does.

For more than two years, since f2c66cd8ee
"/proc/stat: scalability of irq num per cpu" the output of /proc/stat is
broken.
The first field in the "intr" line should contain the sum of all interrupts,
however since the above mentioned change it is always zero.
The reason for that is that a per cpu irq sum variable had been introduced
which got incremented when calling kstat_incr_irqs_this_cpu(). However
on s390 we directly incremented only the per cpu per irq counter by accessing
the array element via kstat_cpu(smp_processor_id()).irqs[...].
So fix this and use the kstat_incr_irqs_this_cpu() wrapper which increments
both: the per cpu per irq counter and the per cpu irq sum counter.

The debug_register/unregister_view() functions call debugfs_remove()

a mutex and therefore can sleep this is not allowed. To fix the problem
we give up the debug_info lock before calling debugfs_remove().

With commit 384a290 (ARM: gic: use a private mapping for CPU target
interfaces), wake-up IPIs now go to all cores as the gic cpu interface
numbering may not follow core numbering. This broke secondary boot on
highbank since the boot address was already set for all secondary cores,
this caused all cores to boot before the kernel was ready.
Fix this by moving the setting of the jump address to
highbank_boot_secondary instead of highbank_smp_prepare_cpus and
highbank_cpu_die. Also, clear the address when we boot. This prevents
cores from booting before they are actually triggered and is also necessary
to get suspend/resume to work.

Summary:
- change exynos file license
. Most of exynos files had been copied from some randome
file and not updated correctly(wrong company name used).
This was our mistakes so chagnes it correctly. For this,
I'm not sure that this patch should go to -fix or -next.
So please give me any comment if there is any problem.
- consider buffer allocation without iommu
. Without iommu, dma_alloc_attrs function allocates some
memory region and returns cpu address so this patch makes
the cpu address to be set to buf->kvaddr correctly
- cleanups to ipp relevant codes.
- use common finish page flip function
. to avoid the duplication of same code, use
exynos_drm_crtc_finish_pageflip function commonly instead
of each one.
- fix fimd resume issue.
. when fimd was turned off by suspend, there was one issue that
the fimd wasn't turned on by resume so fix it chaing resume
condition.

The problem is that the wrong symbol was defined as the default value
for the choice. Using the correct value gets rid of the infinite loop.

"Bug fixes, including two regressions introduced in v3.8. The most
serious of these regressions is a buffer cache leak."
* tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4:

Use device_unregister to replace put_device + device_del for
cleanup, and fix the potential use after free.

After f65aad41772f("MIPS: Cavium: Add EDAC support."), when entering
the "Device Drivers" toplevel menu in menuconfig, the suboptions behind
EDAC appeared merged with the rest of the device drivers types. This was
because the menuconfig option EDAC is querying an EDAC_SUPPORT Kconfig
bool which was defined after the menu definition.
When pushing EDAC_SUPPORT up, before the menu definition, the variable
is defined earlier and the above menuconfig artifact doesn't happen.
Drop a useless menuconfig comment while at it.

This patch fixes use-after-free and double-free bugs in
edac_mc_sysfs_exit(). mci_pdev has single reference and put_device()
calls mc_attr_release() which calls kfree(). The following
device_del() works with already released memory. An another kfree() in
edac_mc_sysfs_exit() releses the same memory again. Great.

- Fix a permissions problem when opening NFSv4 files that only have the
exec bit set.
- Fix a couple of typos in pNFS (inverted logic), and the mount parsing
(missing pointer dereference).
- Work around a series of deadlock issues due to workqueues using
struct work_struct pointer address comparisons in the re-entrancy
tests. Ensure that we don't free struct work_struct prematurely if
our work function involves waiting for completion of other work
items (e.g. by calling rpc_shutdown_client).
- Revert the part of commit 168e4b3 that is causing unnecessary warnings
to be issued in the nfsd callback code.

The mute LED is in this case connected to the Mic1 VREF.
The machine also exposes the following string in BIOS:
"HP_Mute_LED_0_A", so if more machines are coming, it probably
makes sense to try to do something more generic, like for the
IDT codec.

As a result, user space can no longer load kernel modules using

ima: fallback to MODULE_SIG_ENFORCE for existing kernel module syscall
vga-switcheroo with apple-gmux does not switch correctly on my system. The PCI
configuration space is not restored correctly, resulting in MSI not working after switch.
Only useful item in dmesg is:
[ 33.922807] radeon 0000:01:00.0: Refused to change power state, currently in D3
I did some testing, dumping the difference in ms between first succesful switch
from D3 to D0, and it seems that there is slightly more than 20 ms difference when
the device is re-enabled through vga-switcheroo.
So bump the re-enable d3 delay to 20 ms to handle this, which fixes msi not working
on my system after switcheroo-ing. Default d3_delay value is PCI_PM_D3_WAIT, 10 ms.
