The Kconfig options I added to work around broken compilation ended
up screwing up things more, as I used the wrong symbol to control
compilation of the file, resulting in IPv6 fou support to never be built
into the kernel.
Changing CONFIG_NET_FOU_IPV6_TUNNELS to CONFIG_IPV6_FOU fixes that
problem, I had renamed the symbol in one location but not the other,
and as the file is never being used by other kernel code, this did not
lead to a build failure that I would have caught.
After that fix, another issue with the same patch becomes obvious, as we
'select INET6_TUNNEL', which is related to IPV6_TUNNEL, but not the same,
and this can still cause the original build failure when IPV6_TUNNEL is
not built-in but IPV6_FOU is. The fix is equally trivial, we just need
to select the right symbol.
I have successfully build 350 randconfig kernels with this patch
and verified that the driver is now being built.

Now we cannot distinguish that one sk is a udp or sctp style when
we use ss to dump sctp_info. it's necessary to dump it as well.
For sctp_diag, ss support is not officially available, thus there
are no official users of this yet, so we can add this field in the
middle of sctp_info without breaking user API.
v1->v2:
- move 'sctpi_s_type' field to the end of struct sctp_info, so
that it won't cause incompatibility with applications already
built.
- add __reserved3 in sctp_info to make sure sctp_info is 8-byte
alignment.

The MAC address of the physical interface is only copied to the VLAN
when it is first created, resulting in an inconsistency after MAC
address changes of only newly created VLANs having an up-to-date MAC.
The VLANs should continue inheriting the MAC address of the physical
interface until the VLAN MAC address is explicitly set to any value.
This allows IPv6 EUI64 addresses for the VLAN to reflect any changes
to the MAC of the physical interface and thus for DAD to behave as
expected.

This bug was there when the driver was first added in back in year 2000.
It causes a Smatch warning:
drivers/atm/firestream.c:849 process_incoming()
error: buffer overflow 'res_strings' 60 <= 63
There are supposed to be 64 entries in this array and the missing
strings are clearly in the 30 40 range. I added them as reserved 37 to
reserved 40. It's possible that strings are really supposed to be added
in the middle instead of at the end, but this approach is safe, in that
it fixes the bug and doesn't break anything that wasn't already broken.

Commit 84320e1a635fcf90cff4185f029ce9e31bf1d4a7
("ARM: BCM: Clean up SMP support for Broadcom Kona") moved the
"secondary-boot-reg" property from the "cpus" node to the individual "cpu"
nodes but negelected to actually support multiple "secondary-boot-reg"
properties.
This patchset rectifies that omission. Note that the behaviour is changed
slightly in that the "secondary-boot-reg" property is now read in
smp_boot_secondary() rather than smp_prepare_cpus(). This means that any
omissions will now only be reported when and if the cpu in question is being
brought up. It also means that an omission for one cpu will not force
uniprocessor mode.

- Flush GPIO direction setting before locking a GPIO as an IRQ: some
electronics or other poking around in the registers behind our back
may have happened, so flush the direction status before trying to
lock the line for use by IRQs.
- Bail out silently when asked to perform operations on NULL GPIO
descriptors. That is what all the get_*_optional() is about: we
get optional GPIO handles, if they are not there, we get NULL.
- Handle compatible ioctl() correctly: we need to convert the ioctl()

The GICv3 backend of the vgic is quite barrier heavy, in order
to ensure synchronization of the system registers and the
memory mapped view for a potential GICv2 guest.
But when the guest is using a GICv3 model, there is absolutely
no need to execute all these heavy barriers, and it is actually
beneficial to avoid them altogether.
This patch makes the synchonization conditional, and ensures
that we do not change the EL1 SRE settings if we do not need to.

Both our GIC emulations are "strict", in the sense that we either
emulate a GICv2 or a GICv3, and not a GICv3 with GICv2 legacy
support.
But when running on a GICv3 host, we still allow the guest to
tinker with the ICC_SRE_EL1 register during its time slice:
it can switch SRE off, observe that it is off, and yet on the
next world switch, find the SRE bit to be set again. Not very
nice.
An obvious solution is to always trap accesses to ICC_SRE_EL1
(by clearing ICC_SRE_EL2.Enable), and to let the handler return
the programmed value on a read, or ignore the write.
That way, the guest can always observe that our GICv3 is SRE==1
only.

When reading back from the list registers, we need to perform
two actions for level interrupts:
1) clear the soft-pending bit if the interrupt is not pending
anymore *in the list register*
2) resample the line level and propagate it to the pending state
But these two actions shouldn't be linked, and we should *always*
resample the line level, no matter what state is in the list
register. Otherwise, we may end-up injecting spurious interrupts
that have been already retired.

The SET_MODULE_RONX protections are effectively the same as the
DEBUG_RODATA protections we enabled by default back in commit
57efac2f7108e325 ("arm64: enable CONFIG_DEBUG_RODATA by default"). It
seems unusual to have one but not the other.
As evidenced by the help text, the rationale appears to be that
SET_MODULE_RONX interacts poorly with tracing and patching, but both of
these make use of the insn framework, which takes SET_MODULE_RONX into
account. Any remaining issues are bugs which should be fixed regardless
of the default state of the option.
This patch enables DEBUG_SET_MODULE_RONX by default, and replaces the
help text with a new wording derived from the DEBUG_RODATA help text,
which better describes the functionality. Previously, the DEBUG_RODATA
entry was inconsistently indented with spaces, which are replaced with
tabs as with the other Kconfig entries.
Additionally, the wording of recommended defaults is made consistent for
all options. These are placed in a new paragraph, unquoted, as a full
sentence (with a period/full stop) as this appears to be the most common
form per $(git grep 'in doubt').

enabled),
2. 2 GB DDR3 RAM,
3. PowerVR SGX544MP3 GPU (not enabled in DTS),
4. USB 3.0 Host x 1, USB 3.0 OTG x 1, USB 2.0 Host x 4,
5. HDMI 1.4a, MIPI DSI and Display Port (Display Port not on all of
revisions though),
6. eMMC 4.5 and microSD slots.
Comparing this board to Odroid XU3 (more popular), the differences are:
1. Exynos5410 instead of 5422,
2. MIPI DSI LCD connector,
3. Main PMIC: Maxim 77802 instead of S2MPS11,
4. USB3503+LAN9730 instead of integrated LAN9514,
5. eMMC 4.5 instead of eMMC 5.0,
This patch adds initial support for the XU board with working basic
functions, eMMC/SD and USB (including attached ethernet adapter).

Move USB 3.0 DWC and 2.0 EHCI/OHCI nodes from exynos5420.dtsi to
exynos54xx.dtsi common for entire family. For Exynos542x/5800 this
should not have functional impact but for Exynos5410 this effectively
adds USB support.
