In both Armada-375 and Armada-38x MPIC interrupts should be identified by
reading cause register multiplied by the interrupt mask.
A lack of above mentioned multiplication resulted in a bug, caused by the
fact that in Armada-375 and Armada-38x some of the interrupts
(e.g. network interrupts) can be handled either as a GIC or MPIC interrupts.
Therefore during MPIC interrupts handling, cause register shows hits from
interrupts even if they are masked for MPIC but unmasked for a GIC.
This resulted in 'bad IRQ' error, because masked MPIC interrupt without
registered interrupt handler, was trying to be handled during interrupt
handling procedure of some other unmasked MPIC interrupt (e.g. local timer
irq).
This commit fixes that by ensuring that during MPIC interrupt handling only
interrupts that are unmasked for MPIC are processed.

The MSI interrupts use the 16 high doorbells, which are notified by using IRQ1
of the main interrupt controller.
The MSI interrupts were handled correctly for Armada-XP and Armada-370 but not
for Armada-375 and Armada-38x, which use chained handler for the MPIC.
This commit fixes that by checking proper interrupt number in chained handler
for the MPIC.

In powerpc pseries platform dlpar operations, use device_online() and
device_offline() instead of cpu_up() and cpu_down().
Calling cpu_up/down() directly does not update the cpu device offline
field, which is used to online/offline a cpu from sysfs. Calling
device_online/offline() instead keeps the sysfs cpu online value
correct. The hotplug lock, which is required to be held when calling
device_online/offline(), is already held when dlpar_online/offline_cpu()
are called, since they are called only from cpu_probe|release_store().
This patch fixes errors on phyp (PowerVM) systems that have cpu(s)
added/removed using dlpar operations; without this patch, the
/sys/devices/system/cpu/cpuN/online nodes do not correctly show the
online state of added/removed cpus.

The problem is that hardware handled by arm/plat-orion/gpio.c,
require ack for edge irq, and no ack for level irq.
The code handle this issue, by two "struct irq_chip_type" per
one "struct irq_chip_generic". For one "struct irq_chip_generic"
irq_ack pointer is setted, for another it is NULL.
But we have only one mask_cache per two "struct irq_chip_type".
So if we
1)unmask interrupt A for "edge type" trigger,
2)unmask interrupt B for "level type" trigger,
3)unmask interrupt C for "edge type",
we, because of usage of generic irq_gc_mask_clr_bit/irq_gc_mask_set_bit,
have hardware configured to trigger interrupt B on "edge type",
because of shared mask_cache. But kernel think that B is "level type",
so when interrupt B occur via "edge" reason, we don't ack it,
and B triggered again and again.

A second product has come to light which makes use of the A0 stepping
of the Armada XP SoC. A0 stepping has a hardware bug in the i2c core
meaning that hardware offload does not work, resulting in the kernel
failing to boot. The quirk detects that the kernel is running on an A0
stepping SoC and disables the use of hardware offload.
Currently the quirk is only enabled for PlatHome Openblocks AX3. The
AX3 has been produced with both A0 and B0 stepping SoCs. The second
product is the Lenovo Iomega IX4-300d. It seems likely that this
device will also swap from A0 to B0 SoC sometime during its life.
If there are two products using A0, it seems likely there are more
products with A0. Also, since the number of A0 SoCs is limited, these
products are also likely to transition to B0. Hence detecting at run
time is the safest option. So enable the quirk for all Armada XP
boards.
Tested on an AX3 with A0 stepping.

When choosing a random address, the current implementation does not take into
account the reversed space for .bss and .brk sections. Thus the relocated kernel
may overlap other components in memory. Here is an example of the overlap from a
x86_64 kernel in qemu (the ranges of physical addresses are presented):
Physical Address
0x0fe00000 --+--------------------+ <-- randomized base
/ | relocated kernel |
vmlinux.bin | (from vmlinux.bin) |
0x1336d000 (an ELF file) +--------------------+--
\ | | \
0x1376d870 --+--------------------+ |
| relocs table | |
0x13c1c2a8 +--------------------+ .bss and .brk
| | |
0x13ce6000 +--------------------+ |
| | /
0x13f77000 | initrd |--
| |
0x13fef374 +--------------------+
The initrd image will then be overwritten by the memset during early
initialization:
[ 1.655204] Unpacking initramfs...
[ 1.662831] Initramfs unpacking failed: junk in compressed archive
This patch prevents the above situation by requiring a larger space when looking
for a random kernel base, so that existing logic can effectively avoids the
overlap.

The SMC91x is written to explicitly look up the IRQ resource
from the platform device and extract the IRQ and flags, however
the platform_get_irq() does additional things, like call
of_irq_get() in the device tree case, which will translate
the IRQ using the irqdomain and defer the probe if the
IRQ host cannot be found.
As we're not looking up the resource, this will not retrieve
the IRQ flags, but that is better done using
irqd_get_trigger_type(), as the trigger is what the driver
wants to modify. We take care to preserve the semantics that
will make the trigger type provided from the resource
override any local specifier.
Tested on the Nomadik NHK15 which has its SMC91x IRQ line
connected to a STMPE2401 GPIO expander on I2C.

Konrad triggered the following splat below in a 32-bit guest on an AMD
box. As it turns out, in save_microcode_in_initrd_amd() we're using the
*physical* address of the container *after* we have enabled paging and
thus we #PF in load_microcode_amd() when trying to access the microcode
container in the ramdisk range.
Because the ramdisk is exactly there:
[ 0.000000] RAMDISK: [mem 0x35e04000-0x36ef9fff]
and we fault at 0x35e04304.
And since this guest doesn't relocate the ramdisk, we don't do the
computation which will give us the correct virtual address and we end up
with the PA.
So, we should actually be using virtual addresses on 32-bit too by the
time we're freeing the initrd. Do that then!

is a pretty nasty one since we were not allocating a large enough
dma coherent pool for our transmit descriptors, which would work most of the
time, since allocations are contiguous and we could have.
Second patch fixes a less frequent, though highly likley crash when using
CMA allocations.

Callers of bcm_sysport_init_tx_ring() can currently fail, and will
always call bcm_sysport_fini_tx_ring() in a loop ending at the number of
TX queues (32) without checking if the TX ring was successfully
initialized or not.
Update bcm_sysport_fini_tx_ring() to return early and avoid a crash
de-referencing ring->cbs if the TX ring was not initialized, since
ring->cbs is the last part of the initialization done by
bcm_sysport_init_tx_ring() that could fail.

The problem is that pbm->pci_bus->self is NULL.
This code is trying to go through the standard PCI config space
interfaces to read the PCI controller's PCI_STATUS register.
This doesn't work, because we more often than not do not enumerate
the PCI controller as a bonafide PCI device during the OF device
node scan. Therefore bus->self remains NULL.
Existing common code for PSYCHO and PSYCHO-like PCI controllers
handles this properly, by doing the config space access directly.
Do the same here, pbm->pci_ops->{read,write}().

Pull ACPI and power management fixes from Rafael Wysocki:
"These are fixes received after my previous pull request plus one that
has been in the works for quite a while, but its previous version
caused problems to happen, so it's been deferred till now.
Fixed are two recent regressions (MFD enumeration and cpufreq-dt),
ACPI EC regression introduced in 3.17, system suspend error code path
regression introduced in 3.15, an older bug related to recovery from
failing resume from hibernation and a cpufreq-dt driver issue related
to operation performance points.
Specifics:
- Fix a crash on r8a7791/koelsch during resume from system suspend
caused by a recent cpufreq-dt commit (Geert Uytterhoeven).
- Fix an MFD enumeration problem introduced by a recent commit adding
ACPI support to the MFD subsystem that exposed a weakness in the
ACPI core causing ACPI enumeration to be applied to all devices
associated with one ACPI companion object, although it should be
used for one of them only (Mika Westerberg).
- Fix an ACPI EC regression introduced during the 3.17 cycle causing
some Samsung laptops to misbehave as a result of a workaround
targeted at some Acer machines. That includes a revert of a commit
that went too far and a quirk for the Acer machines in question.
From Lv Zheng.
- Fix a regression in the system suspend error code path introduced
during the 3.15 cycle that causes it to fail to take errors from
asychronous execution of "late" suspend callbacks into account
(Imre Deak).
- Fix a long-standing bug in the hibernation resume error code path
that fails to roll back everything correcty on "freeze" callback
errors and leaves some devices in a "suspended" state causing more
breakage to happen subsequently (Imre Deak).
- Make the cpufreq-dt driver disable operation performance points
that are not supported by the VR connected to the CPU voltage plane
with acceptable tolerance instead of constantly failing voltage
scaling later on (Lucas Stach)"

Pull PCI fixes from Bjorn Helgaas:
"These changes, intended for v3.18, fix:
Sysfs
- Fix "enable" filename change (Greg Kroah-Hartman)
An unintentional sysfs filename change in commit 5136b2da770d
("PCI: convert bus code to use dev_groups"), which appeared in
v3.13, changed "enable" to "enabled", and this changes it back.
Old users of "enable" are currently broken and will be helped by
this change. Anything that started to use "enabled" after v3.13
will be broken by this change. If necessary, we can add a symlink
to make both work, but this patch doesn't do that.

Rusty noticed a Really Bad Bug (tm) in my NT fix. The entry code
reads out of bounds, causing the NT fix to be unreliable. But, and
this is much, much worse, if your stack is somehow just below the
top of the direct map (or a hole), you read out of bounds and crash.
Excerpt from the crash:
[ 1.129513] RSP: 0018:ffff88001da4bf88 EFLAGS: 00010296
2b:* f7 84 24 90 00 00 00 testl $0x4000,0x90(%rsp)
That read is deterministically above the top of the stack. I
thought I even single-stepped through this code when I wrote it to
check the offset, but I clearly screwed it up.

The cpsw driver did not support the IFF_ALLMULTI flag which makes dynamic
multicast routing not work. Related to this, when enabling IFF_PROMISC
in switch mode, all registered multicast addresses are flushed, resulting
in only broadcast and unicast traffic being received.
A new cpsw_ale_set_allmulti function now scans through the ALE entry
table and adds/removes the host port from the unregistered multicast
port mask of each vlan entry depending on the state of IFF_ALLMULTI.
In promiscious mode, cpsw_ale_set_allmulti is used to force reception
of all multicast traffic in addition to the unicast and broadcast traffic.
With this change dynamic multicast and promiscious mode both work in
switch mode.

0d961b3b52f566f823070ce2366511a7f64b928c (drivers: net: cpsw: fix buggy
loop condition) accidentally fixed a loop comparison in too many places
while fixing a real bug.
It was correct to fix the dual_emac mode section since there 'i' is used
as an index into priv->slaves which is a 0 based array.
However the other two changes (which are only used in switch mode)
are wrong since there 'i' is actually the ALE port number, and port 0
is the host port, while port 1 and up are the slave ports.
Putting the loop condition back in the switch mode section fixes it.
A comment has been added to point out the intent clearly to avoid future
confusion. Also a comment is fixed that said the opposite of what was
actually happening.

If a driver supports reading EEPROM but no EEPROM is installed in the system,
the driver's get_eeprom_len function returns 0. ethtool will subsequently
try to read that zero-length EEPROM anyway. If the driver does not support
EEPROM access at all, this operation will return -EOPNOTSUPP. If the driver
does support EEPROM access but no EEPROM is installed, the operation will
return -EINVAL. Return -EOPNOTSUPP in both cases for consistency.

With legacy booting, the platform init code was taking care of

may or may not work depending what bootloader has configured or
if the legacy platform code gets called.
Let's add support for the pwrdn and reset GPIOs to the smc91x
driver to fix the issues of smc91x not working properly when
booted in device tree mode.
And let's change n900 to use these settings as some versions
of the bootloader do not configure things properly causing

The VD_OP_GET_VTOC operation will succeed only if the vdisk backend has a

48 (ENOTSUP) if the disk has an EFI label. VTOC disk labels are already
handled by directly reading the disk in block/partitions/sun.c (enabled by
CONFIG_SUN_PARTITION which defaults to y on SPARC). Since port->label is
unused in the driver, remove the call and the field.
