The O2Micro controller only supports tuning at 4-bits. So the host driver
needs to change the bus width while tuning and then set it back when done.
There was a bug in the original implementation in that mmc->ios.bus_width
also wasn't updated. Thus setting the incorrect blocksize in
sdhci_send_tuning which results in a tuning failure.

When Broadcom SDIO cards are idled they go to sleep and a whole
separate subsystem takes over their SDIO communication. This is the
Always-On-Subsystem (AOS) and it can't handle tuning requests.
Specifically, as tested on rk3288-veyron-minnie (which reports having
BCM4354/1 in dmesg), if I force a retune in brcmf_sdio_kso_control()
when "on = 1" (aka we're transition from sleep to wake) by whacking:
bus->sdiodev->func1->card->host->need_retune = 1
...then I can often see tuning fail. In this case dw_mmc reports "All
phases bad!"). Note that I don't get 100% failure, presumably because
sometimes the card itself has already transitioned away from the AOS
itself by the time we try to wake it up. If I force retuning when "on
= 0" (AKA force retuning right before sending the command to go to
sleep) then retuning is always OK.
NOTE: we need _both_ this patch and the patch to avoid triggering
tuning due to CRC errors in the sleep/wake transition, AKA ("brcmfmac:
sdio: Disable auto-tuning around commands expected to fail"). Though
both patches handle issues with Broadcom's AOS, the problems are
distinct:
1. We want to defer (but not ignore) asynchronous (like
timer-requested) tuning requests till the card is awake. However,
we want to ignore CRC errors during the transition, we don't want
to queue deferred tuning request.
2. You could imagine that the AOS could implement retuning but we
could still get errors while transitioning in and out of the AOS.
Similarly you could imagine a seamless transition into and out of
the AOS (with no CRC errors) even if the AOS couldn't handle
tuning.
ALSO NOTE: presumably there is never a desperate need to retune in
order to wake up the card, since doing so is impossible. Luckily the
only way the card can get into sleep state is if we had a good enough
tuning to send it the command to put it into sleep, so presumably that
"good enough" tuning is enough to wake us up, at least with a few
retries.

We want SDIO drivers to be able to temporarily stop retuning when the
driver knows that the SDIO card is not in a state where retuning will
work (maybe because the card is asleep). We'll move the relevant
functions to a place where drivers can call them.

There are certain cases, notably when transitioning between sleep and
active state, when Broadcom SDIO WiFi cards will produce errors on the
SDIO bus. This is evident from the source code where you can see that
we try commands in a loop until we either get success or we've tried
too many times. The comment in the code reinforces this by saying
"just one write attempt may fail"
Unfortunately these failures sometimes end up causing an "-EILSEQ"
back to the core which triggers a retuning of the SDIO card and that
blocks all traffic to the card until it's done.
Let's disable retuning around the commands we expect might fail.

Normally when the MMC core sees an "-EILSEQ" error returned by a host
controller then it will trigger a retuning of the card. This is
generally a good idea.
However, if a command is expected to sometimes cause transfer errors
then these transfer errors shouldn't cause a re-tuning. This
re-tuning will be a needless waste of time. One example case where a
transfer is expected to cause errors is when transitioning between
idle (sometimes referred to as "sleep" in Broadcom code) and active
state on certain Broadcom WiFi SDIO cards. Specifically if the card
was already transitioning between states when the command was sent it
could cause an error on the SDIO bus.
Let's add an API that the SDIO function drivers can call that will
temporarily disable the auto-tuning functionality. Then we can add a
call to this in the Broadcom WiFi driver and any other driver that
might have similar needs.
NOTE: this makes the assumption that the card is already tuned well
enough that it's OK to disable the auto-retuning during one of these
error-prone situations. Presumably the driver code performing the
error-prone transfer knows how to recover / retry from errors. ...and
after we can get back to a state where transfers are no longer
error-prone then we can enable the auto-retuning again. If we truly
find ourselves in a case where the card needs to be retuned sometimes
to handle one of these error-prone transfers then we can always try a
few transfers first without auto-retuning and then re-try with
auto-retuning if the first few fail.
Without this change on rk3288-veyron-minnie I periodically see this in
the logs of a machine just sitting there idle:

This reverts commit 29f6589140a10ece8c1d73f58043ea5b3473ab3e.
After that patch landed I find that my kernel log on
rk3288-veyron-minnie and rk3288-veyron-speedy is filled with:
brcmfmac: brcmf_sdio_bus_sleep: error while changing bus sleep state -110
This seems to happen every time the Broadcom WiFi transitions out of
sleep mode. Reverting the commit fixes the problem for me, so that's
what this patch does.
Note that, in general, the justification in the original commit seemed
a little weak. It looked like someone was testing on a SD card
controller that would sometimes die if there were CRC errors on the
bus. This used to happen back in early days of dw_mmc (the controller
on my boards), but we fixed it. Disabling a feature on all boards
just because one SD card controller is broken seems bad.

The function ixp4xx_irq_setup() references

This is often because ixp4xx_irq_setup lacks a __init

Setting params.phy_utmi_width in dwc2_lowlevel_hw_init() is pointless since
it's value will be overwritten by dwc2_init_params().
This change make sure to take in account the generic PHY width information
during paraminitialisation, done in dwc2_set_param_phy_utmi_width().
By doing so, the phy_utmi_width params can still be overrided by
devicetree specific params and will also be checked against hardware

Enables the FSL EDMA driver by default. This also works around an issue
that imx-i2c driver keeps deferring the probe because of the DMA is not

if the DMA channels will truly become available later (it will never be
available if the DMA driver is not enabled).

The call to sc_buffer_alloc currently returns NULL (no buffer) or
a buffer descriptor.
There is a third case when the port is down. Currently that
returns NULL and this prevents the caller from properly handling the
sc_buffer_alloc() failure. A verbs code link test after the call is
racy so the indication needs to come from the state check inside the allocation
routine to be valid.
Fix by encoding the ECOMM failure like SDMA. IS_ERR_OR_NULL() tests
are added at all call sites. For verbs send, this needs to treat any
error by returning a completion without any MMIO copy.

The hcall H_SET_DAWR is used by a guest to set the data address
watchpoint register (DAWR). This hcall is handled in the host in
kvmppc_h_set_dawr() which can be called in either real mode on the
guest exit path from hcall_try_real_mode() in book3s_hv_rmhandlers.S,
or in virtual mode when called from kvmppc_pseries_do_hcall() in
book3s_hv.c.
The function kvmppc_h_set_dawr() updates the dawr and dawrx fields in
the vcpu struct accordingly and then also writes the respective values
into the DAWR and DAWRX registers directly. It is necessary to write
the registers directly here when calling the function in real mode
since the path to re-enter the guest won't do this. However when in
virtual mode the host DAWR and DAWRX values have already been
restored, and so writing the registers would overwrite these.
Additionally there is no reason to write the guest values here as
these will be read from the vcpu struct and written to the registers
appropriately the next time the vcpu is run.
This also avoids the case when handling h_set_dawr for a nested guest
where the guest hypervisor isn't able to write the DAWR and DAWRX
registers directly and must rely on the real hypervisor to do this for
it when it calls H_ENTER_NESTED.

When propagating mounts across mount namespaces owned by different user
namespaces it is not possible anymore to move or umount the mount in the
less privileged mount namespace.
Here is a reproducer:
sudo mount -t tmpfs tmpfs /mnt
sudo --make-rshared /mnt
# create unprivileged user + mount namespace and preserve propagation
unshare -U -m --map-root --propagation=unchanged
# now change back to the original mount namespace in another terminal:
sudo mkdir /mnt/aaa
sudo mount -t tmpfs tmpfs /mnt/aaa
# now in the unprivileged user + mount namespace
mount --move /mnt/aaa /opt
Unfortunately, this is a pretty big deal for userspace since this is
e.g. used to inject mounts into running unprivileged containers.
So this regression really needs to go away rather quickly.
The problem is that a recent change falsely locked the root of the newly
added mounts by setting MNT_LOCKED. Fix this by only locking the mounts
on copy_mnt_ns() and not when adding a new mount.

Some servers such as Windows 10 will return STATUS_INSUFFICIENT_RESOURCES
as the number of simultaneous SMB3 requests grows (even though the client
has sufficient credits). Return EAGAIN on STATUS_INSUFFICIENT_RESOURCES
so that we can retry writes which fail with this status code.
This (for example) fixes large file copies to Windows 10 on fast networks.

Hardcoding /usr/include/slang is fundamentally incompatible with cross
compilation and will lead to the inability for a cross-compiled
environment to properly detect whether slang is available or not.
If /usr/include/slang is necessary that is a distribution specific
knowledge that could be solved with either a standard pkg-config .pc
file (which slang has) or simply overriding CFLAGS accordingly, but the
default perf Makefile should be clean of all of that.

In which case it simply returns "unknown", like when it can't figure out
the evsel->name value.
This makes this code more robust and fixes a problem in 'perf trace'
where a NULL evsel was being passed to a routine that only used the
evsel for printing its name when a invalid syscall id was passed.

We can't just add the consumed bytes to the arg->augmented.args member,
as it is not void *, so it will access (consumed * sizeof(struct augmented_arg))
in the next augmented arg, totally wrong, cast the member to void pointe
before adding the number of bytes consumed, duh.
With this and hardcoding handling the 'renameat' and 'renameat2'
syscalls in the tools/perf/examples/bpf/augmented_raw_syscalls.c eBPF
proggie, we get:
mv/24388 renameat2(AT_FDCWD, "/tmp/build/perf/util/.bpf-event.o.tmp", AT_FDCWD, "/tmp/build/perf/util/.bpf-event.o.cmd", RENAME_NOREPLACE) = 0

We were just skipping the syscalls not available in a particular
architecture without reflecting this in the number of entries in the
ev_qualifier_ids.nr variable, fix it.
This was done with the most minimalistic way, reusing the index variable
'i', a followup patch will further clean this by making 'i' renamed to
'nr_used' and using 'nr_allocated' in a few more places.

Laura reported that the perf build failed in fedora when we got a glibc
