Object-like macros are different than function-like macros:
https://gcc.gnu.org/onlinedocs/cpp/Object-like-Macros.html
https://gcc.gnu.org/onlinedocs/cpp/Function-like-Macros.html
They are not parsed correctly, generating invalid intermediate
files (xmls) for cases like:
#define BIT_MASK (0xFF << BIT_SHIFT)
where "OxFF <<" is considered to be parameter type.
When parsing, we can differentiate beween these two types of macros by
checking whether there is at least one whitespace b/w "#define" and
first opening parenthesis.

The paragraph on mcelog currently describes kernel v2.6.31. In that
kernel the mce code (for i386, that is) was in transition. Ever since
v2.6.32 the situation is much simpler (eg, mcelog is now needed to
process events on almost all x86 machines, i386 and x86-64). Since this
"document is designed to provide a list of the minimum levels of
software necessary to run the 3.0 kernels" let's just describe that
situation.

If probe fails then we need to call pm_runtime_disable() to balance
out the previous pm_runtime_enable() call. Else it will cause
unbalanced pm_runtime_enable() call in the succeding probe call.
This anomaly was observed when the call to devm_phy_create() failed
with -EPROBE_DEFER.
Balance out the pm_runtime_enable() call in .remove() as well.

This patch introduces a possibility for userspace to set various (so far
two) modes of generating addresses. This is useful for example for
NetworkManager because it can set the mode to NONE and take care of link
local addresses itself. That allow it to have the interface up,
monitoring carrier but still don't have any addresses on it.
One more use-case by Dan Williams:
<quote>
WWAN devices often have their LL address provided by the firmware of the
device, which sometimes refuses to respond to incorrect LL addresses
when doing DHCPv6 or IPv6 ND. The kernel cannot generate the correct LL
address for two reasons:
1) WWAN pseudo-ethernet interfaces often construct a fake MAC address,
or read a meaningless MAC address from the firmware. Thus the EUI64 and
the IPv6LL address the kernel assigns will be wrong. The real LL
address is often retrieved from the firmware with AT or proprietary
commands.
2) WWAN PPP interfaces receive their LL address from IPV6CP, not from
kernel assignments. Only after IPV6CP has completed do we know the LL
address of the PPP interface and its peer. But the kernel has already
assigned an incorrect LL address to the interface.
So being able to suppress the kernel LL address generation and assign
the one retrieved from the firmware is less complicated and more robust.

If the 'next' pointer of the last fragment buffer in a message is not
zeroed before reassembly, we risk ending up with a corrupt message,
since the reassembly function itself isn't doing this.
Currently, when a buffer is retrieved from the deferred queue of the
broadcast link, the next pointer is not cleared, with the result as
described above.
This commit corrects this, and thereby fixes a bug that may occur when
long broadcast messages are transmitted across dual interfaces. The bug
has been present since 40ba3cdf542a469aaa9083fa041656e59b109b90 ("tipc:
message reassembly using fragment chain")

There are several issues in fst_add_one() and fst_init_card():
- invalid pointer dereference at card->ports[card->nports - 1] if
register_hdlc_device() fails for the first port in fst_init_card();
- fst_card_array overflow at fst_card_array[no_of_cards_added]
because there is no checks for array overflow;
- use after free because pointer to deallocated card is left in fst_card_array
if something fails after fst_card_array[no_of_cards_added] = card;
- several leaks on failure paths in fst_add_one().
The patch fixes all the issues and makes code more readable.

Commit 007649375f6af2 ("ext4: initialize multi-block allocator before
checking block descriptors") causes the block group descriptor's count
of the number of free blocks to become inconsistent with the number of
free blocks in the allocation bitmap. This is a harmless form of fs
corruption, but it causes the kernel to potentially remount the file
system read-only, or to panic, depending on the file systems's error
behavior.
Thanks to Eric Whitney for his tireless work to reproduce and to find
the guilty commit.

We are seeing a lot of PMU warnings on POWER8:
Can't find PMC that caused IRQ
Looking closer, the active PMC is 0 at this point and we took a PMU
exception on the transition from negative to 0. Some versions of POWER8
have an issue where they edge detect and not level detect PMC overflows.
A number of places program the PMC with (0x80000000 - period_left),
where period_left can be negative. We can either fix all of these or
just ensure that period_left is always >= 1.

On POWER8 when switching to a KVM guest we set bits in MMCR2 to freeze
the PMU counters. Aside from on boot they are then never reset,
resulting in stuck perf counters for any user in the guest or host.
We now set MMCR2 to 0 whenever enabling the PMU, which provides a sane
state for perf to use the PMU counters under either the guest or the
host.
This was manifesting as a bug with ppc64_cpu --frequency:
$ sudo ppc64_cpu --frequency
WARNING: couldn't run on cpu 0
WARNING: couldn't run on cpu 8
...
WARNING: couldn't run on cpu 144
WARNING: couldn't run on cpu 152
min: 18446744073.710 GHz (cpu -1)
max: 0.000 GHz (cpu -1)
avg: 0.000 GHz
The command uses a perf counter to measure CPU cycles over a fixed
amount of time, in order to approximate the frequency of the machine.
The counters were returning zero once a guest was started, regardless of
weather it was still running or had been shut down.
By dumping the value of MMCR2, it was observed that once a guest is
running MMCR2 is set to 1s - which stops counters from running:
$ sudo sh -c 'echo p > /proc/sysrq-trigger'
CPU: 0 PMU registers, ppmu = POWER8 n_counters = 6
PMC1: 5b635e38 PMC2: 00000000 PMC3: 00000000 PMC4: 00000000
PMC5: 1bf5a646 PMC6: 5793d378 PMC7: deadbeef PMC8: deadbeef
MMCR0: 0000000080000000 MMCR1: 000000001e000000 MMCRA: 0000040000000000

SIAR: 00000000000a51cc SDAR: c00000000fc40000 SIER: 0000000001000000
This is done unconditionally in book3s_hv_interrupts.S upon entering the
guest, and the original value is only save/restored if the host has
indicated it was using the PMU. This is okay, however the user of the
PMU needs to ensure that it is in a defined state when it starts using
it.

These two registers are already saved in the block above. Aside from
being unnecessary, by the time we get down to the second save location
r8 no longer contains MMCR2, so we are clobbering the saved value with
PMC5.
MMCR2 primarily consists of counter freeze bits. So restoring the value
of PMC5 into MMCR2 will most likely have the effect of freezing
counters.

Commit 8d6f7c5a: "powerpc/powernv: Make it possible to skip the IRQHAPPENED
check in power7_nap()" added code that prevents cpus from checking for
pending interrupts just before entering sleep state, which is wrong. These
interrupts are delivered during the soft irq disabled state of the cpu.
A cpu cannot enter any idle state with pending interrupts because they will
never be serviced until the next time the cpu is woken up by some other
interrupt. Its only then that the pending interrupts are replayed. This can result
in device timeouts or warnings about this cpu being stuck.
This patch fixes ths issue by ensuring that cpus check for pending interrupts
just before entering any idle state as long as they are not in the path of split
core operations.

Commit 046d662f4818 "coredump: make core dump functionality optional"
made the coredump optional, but didn't update the spufs code that
depends on it. That leads to build errors such as:
arch/powerpc/platforms/built-in.o: In function `.spufs_arch_write_note':
coredump.c:(.text+0x22cd4): undefined reference to `.dump_emit'
coredump.c:(.text+0x22cf4): undefined reference to `.dump_emit'
coredump.c:(.text+0x22d0c): undefined reference to `.dump_align'
coredump.c:(.text+0x22d48): undefined reference to `.dump_emit'
coredump.c:(.text+0x22e7c): undefined reference to `.dump_skip'
Fix it by adding some ifdefs in the cell code.

Pull ACPI and power management fixes from Rafael Wysocki:
"These are a few regression fixes for ACPI device enumeration and
resources management, intel_pstate and cpufreq, a revert of an ACPI
commit removing user space interfaces in /proc that we incorrectly
thought were not used any more, fixes for some long-standing
concurrency issues in the ACPI EC driver, two ACPI battery driver
fixes, stable-candidate fixes for intel_pstate, an ACPI-related fix
for i915 and two new ACPI video blacklist entries for Win8-oriented
BIOSes.
Specifics:
- Missing device ID for ACPI enumeration of PNP devices that we
overlooked during the recent rework of that code from Zhang Rui.
- Fix for a problem introduced during the 3.14 cycle in the ACPI
device resources management code and causing it to reject all
resources of length 0 although some of them are actually valid
which affects serial ports detection on a number of systems. From
Andy Whitcroft.
- intel_pstate fix for a boot problem on some BayTrail-based systems
introduced by a previous fix related to that platform during the
3.13 cycle from Dirk Brandewie.
- Revert of a 3.13 commit that removed the ACPI AC /proc interface
which turns out to be still needed by some old utilities
(kpowersave from kde 3.5.10 in particular) from Lan Tianyu.
- cpufreq build fix for the davinci ARM platform from Prabhakar Lad
(the breakage was introduced during the 3.10 cycle).
- ACPI-related i915 fix preventing firmware on some Thinkpad laptops
from setting backlight levels incorrectly during AC plug/unplug.
From Aaron Lu.
- Fixes for two nasty race conditions in the ACPI embedded controller
driver that may be responsible for a number of past bug reports
related to the EC from Lv Zhang and a fix for two memory leaks in
error code paths in that driver from Colin Ian King.
- Fixes for a couple of corner-case issues in the intel_pstate driver
(all candidates for -stable) from Dirk Brandewie and Vincent Minet.
- Fixes for two corner-case issues in the ACPI battery driver from
Josef Gajdusek and Lan Tianyu.
- Two new ACPI video blacklist entries for Acer TravelMate B113 and
Dell Inspiron 5737 from Edward Lin and Martin Kepplinger"

====================
Network driver for Armada 375 SoC
This is the fourth round of the Armada 375 network support patchset. I've
tried to address all the feedback provided for last version and I hope the
driver looks better now.
If there's nothing else to fix, we'd like to merge this for v3.17. The first
patch should go through the network tree, and the other patches through
the mvebu tree.
Thanks a lot for all the great review, and feel free to comment some more!
Changes from v3:
* Further optimization of the MTU, MAC and ring parameter change to make
it smoothier.
* Lots of cleanups in the parser configuration code, most of them addressing
the feedback from Francois. This include fixing: missing curly braces,
excessive parenthesis, excessive scope, and making several functions
more readable.
* Removed the Rx/Tx queue number module parameter. There's no reason to
use any other than the default hardware-defined value.
Changes from v2:
* Reworked mvpp2_prs_tcam_first_free() as suggested by Joe and Francois,
to have a single loop instead of two.
* Replaced mvpp2_cpu_interrupts_enable/disable(pp, cpu) with one function
that enables/disable interrupts on all the CPUs at once.
* Factor out Tx descriptor DMA unmap + descriptor put sequence to have
more readable code, as suggested by Francois.
* Remove redundant netif_running() checks in the ingress and egress path,
as suggested by Francois.
* Reworked ring parameter, MTU and MAC address setting to produce a
more gentle modification of the parameter, and have a fallback in the
event of a failure.
* Fixed a percpu memory leak on error path, also noted by Francois.
* Removed the usage of the legacy net_device irq field, requested by
Francois.
* Removed the unneeded multiple Tx port support. It was hardcoded to a single
Tx port in the previous version so we decided to drop it and simplify the
code.
* Optimize the on_each_cpu() calls to clear the sent counters and the
TX_DONE pkts coalescing setting. on_each_cpu is expensive so it's better
to minize the calls to it.
Changes from v1:
* Marcin Wojtas is the author of the driver, so I fixed authorship
for patch 1/3:
"ethernet: Add new driver for Marvell Armada 375 network unit"
This patchset adds a new network driver to support the network controller
in Armada 375 SoC.
The network interfaces share a common hardware unit called Packet Processor,
which contains a common register space and per-port register spaces.
The new network unit has different RXQ and TXQ management. The ports
associate so-called per-port "logical queues" which are mapped to "physical
queues". The latter are shared among the ports.
Fo the egress part, the mapping for each port is predefined by hardware.
The egress path incorporates so-called aggregation queues (one per CPU),
from where the data is passed to the physical queues and then via prefetch
buffer to the TxDMA.
The ingress path has a Parser and Classifier (PnC) and a Buffer Manager (BM)
whose usage is obligatory. We are only implementing a simple configuration
for the Parser and Classifier, yet the code is considerably large.
This network unit has other optional features like xPON, WoL, Hardware
Forwarding, and more. This initial commit doesn't provide support for these.
The mvpp2 network driver has been written by Marcin Wojtas and then reviewed
and cleaned up by Ezequiel Garcia.

This commit adds a new network driver for the network controller in Marvell
Armada 375 SoC.
Given the controller is very different from the ones in the other Marvell
SoCs that use the mv643xx_eth (Kirkwood, Orion, Discovery) and mvneta
(Armada 370/38x/XP) drivers, a new driver is needed.
