Filling in the padding slot in the bpf structure as a bug fix in 'ne'

I used bad names in my clumsiness when rewriting many board
files to use GPIO descriptors instead of platform data. A few
had the platform_device ID set to -1 which would indeed give
the device name "i2c-gpio".
But several had it set to >=0 which gives the names
"i2c-gpio.0", "i2c-gpio.1" ...
Fix the offending instances in the ARM tree. Sorry for the
mess.

another problem happened.
It's so late time to fix the later problem so I decide to reverting the

S390 bpf_jit.S is removed in net-next and had changes in 'net',
since that code isn't used any more take the removal.
TLS data structures split the TX and RX components in 'net-next',
put the new struct members from the bug fix in 'net' into the RX
part.
The 'net-next' tree had some reworking of how the ERSPAN code works in
the GRE tunneling code, overlapping with a one-line headroom
calculation fix in 'net'.
Overlapping changes in __sock_map_ctx_update_elem(), keep the bits
that read the prog members via READ_ONCE() into local variables

"A handful of fixes. I've been queuing them up a bit too long so the
list is longer than it otherwise would have been spread out across a
few -rcs.
In general, it's a scattering of fixes across several platforms,
nothing truly serious enough to point out.
There's a slightly larger batch of them for the Davinci platforms due
to work to bring them back to life after some time, so there's a
handful of regressions, some of them going back very far, others more
recent.
There's also a few patches fixing DT on Renesas platforms since they
changed some bindings without remaining backwards compatible,
splitting up describing LVDS as a proper bridge instead of having it
as part of the display unit.
We could push for them to be backwards compatible with old device
trees, but it's likely to regress eventually if nobody's actually
using said compatibility"

SIGFPE") broke the siginfo structure for userspace triggered signals,
causing the strace testsuite to regress. Fix this by eliminating
the FPE_FIXME definition (which is at the root of the breakage) and
use FPE_FLTINV instead for the case where the hardware appears to be

You can build a kernel in a cross compiling environment that doesn't
have perl in the $PATH. Commit 429f7a062e3b broke that for 32 bit
ARM. Fix it.
As reported by Stephen Rothwell, it appears that the symbols can be
either part of the BSS section or absolute symbols depending on the
binutils version. When they're an absolute symbol, the $(( ))
operator errors out and the build fails. Fix this as well.

How we got to machine_crash_nonpanic_core() (iow, from an IPI, etc) is
not interesting for debugging a crash. The more interesting context
is the parent context prior to the IPI being received.
Record the parent context register state rather than the register state
in machine_crash_nonpanic_core(), which is more relevant to the failing
condition.

When a panic() occurs, the kexec code uses smp_send_stop() to stop
the other CPUs, but this results in the CPU register state not being
saved, and gdb is unable to inspect the state of other CPUs.
Commit 0ee59413c967 ("x86/panic: replace smp_send_stop() with kdump
friendly version in panic path") addressed the issue on x86, but
ignored other architectures. Address the issue on ARM by splitting
out the crash stop implementation to crash_smp_send_stop() and
adding the necessary protection.

Daniel Borkmann says:
====================
pull-request: bpf-next 2018-05-17
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Provide a new BPF helper for doing a FIB and neighbor lookup
in the kernel tables from an XDP or tc BPF program. The helper
provides a fast-path for forwarding packets. The API supports
IPv4, IPv6 and MPLS protocols, but currently IPv4 and IPv6 are
implemented in this initial work, from David (Ahern).
2) Just a tiny diff but huge feature enabled for nfp driver by
extending the BPF offload beyond a pure host processing offload.
Offloaded XDP programs are allowed to set the RX queue index and
thus opening the door for defining a fully programmable RSS/n-tuple
filter replacement. Once BPF decided on a queue already, the device
data-path will skip the conventional RSS processing completely,
from Jakub.
3) The original sockmap implementation was array based similar to
devmap. However unlike devmap where an ifindex has a 1:1 mapping
into the map there are use cases with sockets that need to be
referenced using longer keys. Hence, sockhash map is added reusing
as much of the sockmap code as possible, from John.
4) Introduce BTF ID. The ID is allocatd through an IDR similar as
with BPF maps and progs. It also makes BTF accessible to user
space via BPF_BTF_GET_FD_BY_ID and adds exposure of the BTF data
through BPF_OBJ_GET_INFO_BY_FD, from Martin.
5) Enable BPF stackmap with build_id also in NMI context. Due to the
up_read() of current->mm->mmap_sem build_id cannot be parsed.
This work defers the up_read() via a per-cpu irq_work so that
at least limited support can be enabled, from Song.
6) Various BPF JIT follow-up cleanups and fixups after the LD_ABS/LD_IND
JIT conversion as well as implementation of an optimized 32/64 bit
immediate load in the arm64 JIT that allows to reduce the number of
emitted instructions; in case of tested real-world programs they
were shrinking by three percent, from Daniel.
7) Add ifindex parameter to the libbpf loader in order to enable
BPF offload support. Right now only iproute2 can load offloaded
BPF and this will also enable libbpf for direct integration into
other applications, from David (Beckett).
8) Convert the plain text documentation under Documentation/bpf/ into
RST format since this is the appropriate standard the kernel is
moving to for all documentation. Also add an overview README.rst,
from Jesper.
9) Add __printf verification attribute to the bpf_verifier_vlog()
helper. Though it uses va_list we can still allow gcc to check
the format string, from Mathieu.
10) Fix a bash reference in the BPF selftest's Makefile. The '|& ...'
is a bash 4.0+ feature which is not guaranteed to be available
when calling out to shell, therefore use a more portable variant,
from Joe.
11) Fix a 64 bit division in xdp_umem_reg() by using div_u64()
instead of relying on the gcc built-in, from Björn.
12) Fix a sock hashmap kmalloc warning reported by syzbot when an
overly large key size is used in hashmap then causing overflows
in htab->elem_size. Reject bogus attr->key_size early in the
sock_hash_alloc(), from Yonghong.
13) Ensure in BPF selftests when urandom_read is being linked that
--build-id is always enabled so that test_stacktrace_build_id[_nmi]
won't be failing, from Alexei.
14) Add bitsperlong.h as well as errno.h uapi headers into the tools
header infrastructure which point to one of the arch specific
uapi headers. This was needed in order to fix a build error on
some systems for the BPF selftests, from Sirio.
15) Allow for short options to be used in the xdp_monitor BPF sample
code. And also a bpf.h tools uapi header sync in order to fix a
selftest build failure. Both from Prashant.
16) More formally clarify the meaning of ID in the direct packet access
section of the BPF documentation, from Wang.

kvm_read_guest() will eventually look up in kvm_memslots(), which requires
either to hold the kvm->slots_lock or to be inside a kvm->srcu critical
section.
In contrast to x86 and s390 we don't take the SRCU lock on every guest
exit, so we have to do it individually for each kvm_read_guest() call.
Provide a wrapper which does that and use that everywhere.
Note that ending the SRCU critical section before returning from the
kvm_read_guest() wrapper is safe, because the data has been *copied*, so
we don't need to rely on valid references to the memslot anymore.

commit b38434145b34 ("ARM: davinci: irqs: Correct McASP1 TX interrupt

When INTPRIn register setting for an interrupt is left at 0, it is
mapped to FIQ by the AINTC causing the timer interrupt to not get
generated.
Fix it by including an entry for timer0_12 in interrupt priority map
array. While at it, move the clockevent comment to the right place.

platform_domain_notifier contains a variable sized array, which the
pm_clk_notify() notifier treats as a NULL terminated array:
for (con_id = clknb->con_ids; *con_id; con_id++)
pm_clk_add(dev, *con_id);
Omitting the initialiser for con_ids means that the array is zero
sized, and there is no NULL terminator. This leads to pm_clk_notify()
overrunning into what ever structure follows, which may not be NULL.
This leads to an oops:

Fixes for omap variants for v4.17
This series of patches contains one BUG fix for trace if
CONFIG_DEBUG_PREEMPT is enabled and a regression fix for omap1 FIQ
handling on ams-delta. Then there's a dts fix for missing SoC
compatible on ti81xx board dts files that did matter until we added
the clkctrl clocks and without that some clocks are now not found.
Then there are two logicpd-som-lv specific dts fixes that fix
misconfigured pins for WLAN and audio. Turns out we had to revert
the third one because it caused another regression for USB.

Renesas ARM Based SoC Fixes for v4.17
Fix LVDS output on Gen2 boards
Laurent Pincart says "This patch series fixes LVDS output support on the
Lager, Koelsh, Porter and Gose boards that broke in v4.17-rc1 due to the
combination of the R-Car DU LVDS driver rework and the DT move of all
on-SoC peripherals to a /soc node.
We could handle the problem in the R-Car DU LVDS DT backward compatibility
code, but that fix would only be used for v4.17 as in v4.18 the Gen2 DT
will move to the new LVDS DT bindings. I thus propose merging these three
patches in v4.17 already to fix the problem as this is the simplest
solution."

The bpf syscall and selftests conflicts were trivial
overlapping changes.
The r8169 change involved moving the added mdelay from 'net' into a
different function.
A TLS close bug fix overlapped with the splitting of the TLS state
into separate TX and RX parts. I just expanded the tests in the bug
fix from "ctx->conf == X" into "ctx->tx_conf == X && ctx->rx_conf
== X".

Pass the 'fsl,sec-era' property to properly describe the

This error happens because the 'fsl,sec-era' is not passed via
device tree.
The era information is used in various places inside drivers/crypto/caam,
so pass the correct version via device tree.

Commit 4c9a27a6c66d ("ARM: tegra: Fix ULPI regression on Tegra20") changed
"ulpi-link" clock from CDEV2 to PLL_P_OUT4. Turned out that PLL_P_OUT4 is
the parent of CDEV2 clock and original clock setup of "ulpi-link" was
correct. The reverted patch was fixing USB for one board and broke the
other, now Tegra's clk driver correctly sets parent for the CDEV2 clock
and hence patch could be reverted safely, restoring USB for all of the
boards.

The missing "compatible" entries are needed by drivers/clk/ti/clkctrl.c,
and without them the structures initialized in drivers/clk/ti/clk-814x.c
are not passed to configuration code. The result is a "not found from
clkctrl data" error message, although boot proceeds anyway.
The reason why the compatible is not found is because the board specific
files override the SoC compatible without including it. This did not
cause any issues until with the clkctrl nodes got introduced.
Very lightly tested on a (lurching) AM3874 design that's in the middle
of a kernel upgrade from TI's abandoned 2.6.37 tree.
Also tested on j5eco-evm and hp-t410 to verify the clkctrl clocks are
found.

The deferred_fiq handler used to limit hardware operations to IRQ
unmask only, relying on gpio-omap assigned handler performing the ACKs.
Since commit 80ac93c27441 ("gpio: omap: Fix lost edge interrupts") this
is no longer the case as handle_edge_irq() has been replaced with
handle_simmple_irq() which doesn't touch the hardware.
Add single ACK operation per each active IRQ pin to the handler. While
being at it, move unmask operation out of irq_counter loop so it is
also called only once for each active IRQ pin.

The GPIO chip is called davinci_gpio.0 in legacy mode. Fix it, so that
I2C can correctly lookup the recovery gpios.
Note that it is the gpio-davinci driver that sets the gpiochip label to
davinci_gpio.0.
Also, the I2C device uses an id of 1 on DM644x and DM355.
While at it, convert to using GPIO_TO_PIN() for referring to GPIO pin
numbers, like it is done in rest of the board support files.
