The loopback feature is only supported on a few drivers like broadcom,
mellanox, etc. The default veth driver has not supported it yet. To avoid
returning failed and making the runner feel confused, let's just skip
the test on drivers that not support loopback.

Some adapters need a fence Work Entry to handle retransmission. Currently
the driver checks for this condition, only if the Send queue entry is
signalled. Implement the condition check, irrespective of the signalled
state of the Work queue entries
Failure to add the fence can result in access to memory that is already
marked as completed, triggering data corruption, transmission failure,
IOMMU failures, etc.

The driver returns an error code for MR dereg, but frees the MR structure.
When the MR dereg is retried due to previous error, the system crashes as

Pull thread fixes from Christian Brauner:
"Here are two fixes:
- Panic earlier when global init exits to generate useable coredumps.
Currently, when global init and all threads in its thread-group
have exited we panic via:
do_exit()
-> exit_notify()
-> forget_original_parent()
-> find_child_reaper()
This makes it hard to extract a useable coredump for global init
from a kernel crashdump because by the time we panic exit_mm() will
have already released global init's mm. We now panic slightly
earlier. This has been a problem in certain environments such as
Android.
- Fix a race in assigning and reading taskstats for thread-groups
with more than one thread.
This patch has been waiting for quite a while since people
disagreed on what the correct fix was at first"

LTP memfd_create04 started failing for some huge page sizes
after v5.4-10135-gc3bfc5dd73c6.
The problem is the check introduced to for_each_hstate() loop that
should skip default_hstate_idx. Since it doesn't update 'i' counter,
all subsequent huge page sizes are skipped as well.

Prior to commit 858805b336be ("kbuild: add $(BASH) to run scripts with
bash-extension"), this shell script was almost always run by bash since
bash is usually installed on the system by default.
Now, this script is run by sh, which might be a symlink to dash. On such
distributions, the following code emits an error:
local dev=`LC_ALL=C ls -l "${location}"`
You can reproduce the build error, for example by setting
CONFIG_INITRAMFS_SOURCE="/dev".
GEN usr/initramfs_data.cpio.gz
./usr/gen_initramfs_list.sh: 131: local: 1: bad variable name
make[1]: *** [usr/Makefile:61: usr/initramfs_data.cpio.gz] Error 2
This is because `LC_ALL=C ls -l "${location}"` contains spaces.
Surrounding it with double-quotes fixes the error.

The Advantech PCI-1713 has 32 analog input channels, but an incorrect
bit-mask in the definition of the `PCI171X_MUX_CHANH(x)` and
PCI171X_MUX_CHANL(x)` macros is causing channels 16 to 31 to be aliases
of channels 0 to 15. Change the bit-mask value from 0xf to 0xff to fix
it. Note that the channel numbers will have been range checked already,
so the bit-mask isn't really needed.

In order to handle direct calls along side of function graph tracer, a check
is made to see if the address being traced by the function graph tracer is a
direct call or not. To get the address used by direct callers, the return
address is subtracted by MCOUNT_INSN_SIZE.
For some archs with certain configurations, MCOUNT_INSN_SIZE is undefined
here. But these should not be using direct calls anyway. Just define
MCOUNT_INSN_SIZE to zero in this case.

When tpm driver's message overtime dw_spi_irq() and dw_spi_transfer_one

Otherwise dw_spi_transfer_one set dw rx/tx buffer and then open irq,

The .set_ramp_delay should be for bd70528_buck_ops only.
Setting .set_ramp_delay for for bd70528_ldo_ops causes problem because
BD70528_MASK_BUCK_RAMP (0x10) overlaps with BD70528_MASK_LDO_VOLT (0x1f).
So setting ramp_delay for LDOs may change the voltage output, fix it.

The asm/cpu_device_id.h header is not actually needed here,

Declaring __current_thread_info as a global register variable has the
effect of preventing GCC from saving & restoring its value in cases
where the ABI would typically do so.
To quote GCC documentation:
> If the register is a call-saved register, call ABI is affected: the
> register will not be restored in function epilogue sequences after the
> variable has been assigned. Therefore, functions cannot safely return
> to callers that assume standard ABI.
When our position independent VDSO is built for the n32 or n64 ABIs all
functions it exposes should be preserving the value of $gp/$28 for their
caller, but in the presence of the __current_thread_info global register
variable GCC stops doing so & simply clobbers $gp/$28 when calculating
the address of the GOT.
In cases where the VDSO returns success this problem will typically be
masked by the caller in libc returning & restoring $gp/$28 itself, but
that is by no means guaranteed. In cases where the VDSO returns an error
libc will typically contain a fallback path which will now fail
(typically with a bad memory access) if it attempts anything which
relies upon the value of $gp/$28 - eg. accessing anything via the GOT.
One fix for this would be to move the declaration of
__current_thread_info inside the current_thread_info() function,
demoting it from global register variable to local register variable &
avoiding inadvertently creating a non-standard calling ABI for the VDSO.
Unfortunately this causes issues for clang, which doesn't support local
register variables as pointed out by commit fe92da0f355e ("MIPS: Changed
current_thread_info() to an equivalent supported by both clang and GCC")
which introduced the global register variable before we had a VDSO to
worry about.
Instead, fix this by continuing to use the global register variable for
the kernel proper but declare __current_thread_info as a simple extern
variable when building the VDSO. It should never be referenced, and will
cause a link error if it is. This resolves the calling convention issue
for the VDSO without having any impact upon the build of the kernel
itself for either clang or gcc.

Marc Kleine-Budde says:
====================
pull-request: can 2020-01-02
this is a pull request of 9 patches for net/master.
The first 5 patches target all the tcan4x5x driver. The first 3 patches
of them are by Dan Murphy and Sean Nyekjaer and improve the device
initialization (power on, reset and get device out of standby before
register access). The next patch is by Dan Murphy and disables the INH
pin device-state if the GPIO is unavailable. The last patch for the
tcan4x5x driver is by Gustavo A. R. Silva and fixes an inconsistent
PTR_ERR check in the tcan4x5x_parse_config() function.
The next patch is by Oliver Hartkopp and targets the generic CAN device
infrastructure. It ensures that an initialized headroom in outgoing CAN
sk_buffs (e.g. if injected by AF_PACKET).
The last 2 patches are by Johan Hovold and fix the kvaser_usb and gs_usb
drivers by always using the current alternate setting not blindly the
first one.

Before ip_tunnel_ecn_encap() and udp_tunnel_xmit_skb() we should filter
tos value by RT_TOS() instead of using config tos directly.
vxlan_get_route() would filter the tos to fl4.flowi4_tos but we didn't
return it back, as geneve_get_v4_rt() did. So we have to use RT_TOS()
directly in function ip_tunnel_ecn_encap().

The variables 'window_interval' is u64 and do_div()
truncates it to 32 bits, which means it can test
non-zero and be truncated to zero for division.
The unit of window_interval is nanoseconds,
so its lower 32-bit is relatively easy to exceed.
Fix this issue by using div64_u64() instead.

This reverts commit 8243186f0cc7 ("fs: remove ksys_dup()") and the
subsequent fix for it in commit 2d3145f8d280 ("early init: fix error
handling when opening /dev/console").
Trying to use filp_open() and f_dupfd() instead of pseudo-syscalls
caused more trouble than what is worth it: it requires accessing vfs
internals and it turns out there were other bugs in it too.
In particular, the file reference counting was wrong - because unlike
the original "open+2*dup" sequence it used "filp_open+3*f_dupfd" and
thus had an extra leaked file reference.
That in turn then caused odd problems with Androidx86 long after boot
becaue of how the extra reference to the console kept the session active
even after all file descriptors had been closed.
