For beagle x15, both the vdd and io lines are connected to the
same regulator (ldo1_reg). However vmmc_aux is populated to vdd_3v3.

Looks like I made a typo on the control base, all the 81xx
SoCs have it at 0x48140000 base. We've just gotten away with
the typo as the Ethernet phy was configured by the bootloader
on my test system and we're not yet using the pinctrl.
In addition to fixing the contol base, we need to also use the
right Ethernet phy flags to initialize it. And we are still
missing the PLL driver for dm814x and only relying on the
divider and mux clocks.

Let's fix pinmux address of gpio 170 used by tfp410 powerdown-gpio.
According to the OMAP35x Technical Reference Manual
CONTROL_PADCONF_I2C3_SDA[15:0] 0x480021C4 mode0: i2c3_sda
CONTROL_PADCONF_I2C3_SDA[31:16] 0x480021C4 mode4: gpio_170
the pinmux address of gpio 170 must be 0x480021C6.
The former wrong address broke i2c3 (used by hdmi ddc), resulting in
kernel message:
omap_i2c 48060000.i2c: controller timed out

In capture, there is chance that hw_ptr reported at IRQ is
a little smaller than period_size due to internal AFE buffer.
In the case of ping-pong buffer:
|xxxxxxxxxxxxxxxxxxxxxxxxxxxx--|-----------------------------|
hw_ptr < period_size
This available buffer will not be read since its size is smaller than
avail_min (which is period_size by default), and read thread continues
to sleep. If the next hw_ptr is just a little larger than buffer_size,
overrun occurs. One more period can hold the possible unread buffer.

The APIC LVTT register is MMIO mapped but the TSC_DEADLINE register is an
MSR. The write to the TSC_DEADLINE MSR is not serializing, so it's not
guaranteed that the write to LVTT has reached the APIC before the
TSC_DEADLINE MSR is written. In such a case the write to the MSR is
ignored and as a consequence the local timer interrupt never fires.
The SDM decribes this issue for xAPIC and x2APIC modes. The
serialization methods recommended by the SDM differ.
xAPIC:
"1. Memory-mapped write to LVT Timer Register, setting bits 18:17 to 10b.
2. WRMSR to the IA32_TSC_DEADLINE MSR a value much larger than current time-stamp counter.
3. If RDMSR of the IA32_TSC_DEADLINE MSR returns zero, go to step 2.
4. WRMSR to the IA32_TSC_DEADLINE MSR the desired deadline."
x2APIC:
"To allow for efficient access to the APIC registers in x2APIC mode,
the serializing semantics of WRMSR are relaxed when writing to the
APIC registers. Thus, system software should not use 'WRMSR to APIC
registers in x2APIC mode' as a serializing instruction. Read and write
accesses to the APIC registers will occur in program order. A WRMSR to
an APIC register may complete before all preceding stores are globally
visible; software can prevent this by inserting a serializing
instruction, an SFENCE, or an MFENCE before the WRMSR."
The xAPIC method is to just wait for the memory mapped write to hit
the LVTT by checking whether the MSR write has reached the hardware.
There is no reason why a proper MFENCE after the memory mapped write would
not do the same. Andi Kleen confirmed that MFENCE is sufficient for the
xAPIC case as well.
Issue MFENCE before writing to the TSC_DEADLINE MSR. This can be done
unconditionally as all CPUs which have TSC_DEADLINE also have MFENCE
support.

The recent ioapic cleanups changed the affinity setting in
setup_ioapic_dest() from a direct write to the hardware to the delayed
affinity setup via irq_set_affinity().
That results in a warning from chained_irq_exit():
WARNING: CPU: 0 PID: 5 at kernel/irq/migration.c:32 irq_move_masked_irq
[<ffffffff810a0a88>] irq_move_masked_irq+0xb8/0xc0
[<ffffffff8103c161>] ioapic_ack_level+0x111/0x130
[<ffffffff812bbfe8>] intel_gpio_irq_handler+0x148/0x1c0
The reason is that irq_set_affinity() does not write directly to the
hardware. It marks the affinity setting as pending and executes it
from the next interrupt. The chained handler infrastructure does not
take the irq descriptor lock for performance reasons because such a
chained interrupt is not visible to any interfaces. So the delayed
affinity setting triggers the warning in irq_move_masked_irq().
Restore the old behaviour by calling the set_affinity function of the
ioapic chip in setup_ioapic_dest(). This is safe as none of the
interrupts can be on the fly at this point.

Fix lookup of existing match/target structures in the corresponding list
by skipping the family check if NFPROTO_UNSPEC is used.
This is resulting in the allocation and insertion of one match/target
structure for each use of them. So this not only bloats memory
consumption but also severely affects the time to reload the ruleset
from the iptables-compat utility.
After this patch, iptables-compat-restore and iptables-compat take
almost the same time to reload large rulesets.

We can't re-use the physoutdev storage area.

2. for same reason, we crash in physdev match in FORWARD or later if
skb is routed instead of bridged.

Setting the dm-crypt device's max_segment_size to PAGE_SIZE is an
unfortunate constraint that is required to avoid the potential for
exceeding dm-crypt's underlying device's max_segments limits -- due to
crypt_alloc_buffer() possibly allocating pages for the encryption bio
that are not as physically contiguous as the original bio.
It is interesting to note that this problem was already fixed back in
2007 via commit 91e106259 ("dm crypt: use bio_add_page"). But Linux 4.0
commit cf2f1abfb ("dm crypt: don't allocate pages for a partial
request") regressed dm-crypt back to _not_ using bio_add_page(). But
given dm-crypt's cpu parallelization changes all depend on commit
cf2f1abfb's abandoning of the more complex io fragments processing that
dm-crypt previously had we cannot easily go back to using
bio_add_page().
So all said the cleanest way to resolve this issue is to fix dm-crypt to
properly constrain the original bios entering dm-crypt so the encryption
bios that dm-crypt generates from the original bios are always
compatible with the underlying device's max_segments queue limits.
It should be noted that technically Linux 4.3 does _not_ need this fix
because of the block core's new late bio-splitting capability. But, it
is reasoned, there is little to be gained by having the block core split
the encrypted bio that is composed of PAGE_SIZE segments. That said, in
the future we may revert this change.

The 'struct machine' represents the machine where the samples were/are
being collected, and we also have a 'struct perf_env' with extra details
about such machine, that we were collecting at 'perf.data' creation time
but we also needed when no perf.data file is being used, such as in
'perf top'.
So, get those structs closer together, as they provide a bigger picture
of the sample's environment.
In 'perf session', when the file argument is NULL, we can assume that
the tool is sampling the running machine, so point machine->env to
the global put in place in previous patches, while set it to the
perf_header.env one when reading from a file.
This paves the way for machine->env to be used in
perf_event__preprocess_sample to populate addr_location.socket.

Now if one needs the CPU topology map for the running machine, one needs
to call perf_env__read_cpu_topology_map(perf_env) and the info will be

$ ./sysfs__read_ull
devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq
/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq=3200000

I.e. find out the first online CPU, then read its cpufreq info.
But do it in tools/lib/api/, so that other tools/ living code can use
it, not just perf.

Move this from two globals to perf_env global, that eventually will
be just perf_header->env or something else, to ease the refactoring
series, leave it as a global and go on reading more of its fields,
not as part of the header writing process but as a perf_env init one
that will be used for perf.data-less situations.

Since it can be used separately from 'perf_session' and 'perf_header',
move it to separate include file and object, next csets will try to move
a perf_env__init() routine.

In preparation for introducing more arrays of tests, e.g. "arch tests"
(architecture-specific tests), abstract the code to iterate over the
list of tests into a helper function.
This way, code that uses a 'struct test' doesn't need to worry about how
the tests are grouped together and changes to the list of tests doesn't
require changes to the code using it.

When restoring the system register state for an AArch32 guest at EL2,
writes to DACR32_EL2 may not be correctly synchronised by Cortex-A57,
which can lead to the guest effectively running with junk in the DACR
and running into unexpected domain faults.
This patch works around the issue by re-ordering our restoration of the
AArch32 register aliases so that they happen before the AArch64 system
registers. Ensuring that the registers are restored in this order
guarantees that they will be correctly synchronised by the core.

The gpio-desc migration done in v4.0 caused a regression
with legacy boots due to reversed reset logic.
e.g. omap3-beagle USB host breaks on legacy boot.
Request the reset GPIO with GPIOF_ACTIVE_LOW flag so that
it matches the driver logic and pin behaviour.

If a failure happens early in udc_pci_probe(), error handling code
just kfree(dev) and returns. The patch adds proper resource
deallocations in udc_pci_probe() itself,
since udc_pci_remove() is not suitabe to be called so early
in initialization process.
By the way, iounmap(dev->regs) is replaced by iounmap(dev->virt_addr)
in udc_pci_remove() for clarity.

The change ensures otg is not in a A- state when checking for VBUS in
peripheral mode.
musb_start() where VBUS checking is in can be called in many situations.
One example is in babble recovery routine, in which otg is transitioning
from A-HOST to A-WAIT-BCON, but VBUS discharge takes time, so
musb->is_active could be set to 1 due to this improper checking, then it
causes musb_bus_suspend() failed which leads to warning log message
flooding.
