When using Marvell WiFi SDIO cards, it is not uncommon for Linux WiFi
driver to fully lose the communication channel to the firmware running
on the card. Presumably the firmware on the card has a bug or two in
it and occasionally crashes.
The Marvell WiFi driver attempts to recover from this
As described in the patch ("mmc: core: Add sdio_trigger_replug()
API"), the current mwifiex_sdio_card_reset() is broken in the cases
where we're running Bluetooth on a second SDIO func on the same card
as WiFi. The problem goes away if we just use the
sdio_trigger_replug() API call.
NOTE: Even
As talked about in the thread at:
http://lkml.kernel.org/r/CAD=FV=X7P2F1k_zwHc0mbtfk55-rucTz_GoDH=pl6zwqkyc...@mail.gmail.com
...when the Marvell WiFi card tries to reset itself it kills
Bluetooth. It was observed that we could re-init the card properly by
unbinding / rebinding the host

Dear All,
Here are some patches which help tune USB 3.0 phy.
changes have been testing on Odroid XU3 / XU4 / HC1.
with suspend and resume working with usb hdd device connected.
These patches have been build on top on Marek Szyprowski
Fix USB3.0 DRD PHY calibration issues.

Now there are three small local headers. Some contain functions which are
only used in one source file.
Move all the inlines and declarations into a single local header and the
inlines which are only used in one source file into that.

arch_smt_update() will be used to control IPI/NMI broadcasting via the
shorthand mechanism. Keeping it in the bugs file and calling the apic
function from there is possible, but not really intuitive.
Move it to a neutral place and invoke the bugs function from there.
No functional change.
Only used locally.

This is merily a refresh of V2.

- Fix the NMI_VECTOR/VECTOR_NMI typo in kgdb
- Remove the misleading vector 0-31 wording
It applies on top of:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git
apic->send_IPI_allbutself() takes a vector number as argument.
APIC_DM_NMI is clearly not a vector number. It's defined to 0x400 which is
outside the vector space.
Use NMI_VECTOR instead as that's what it is intended to be.

The SDM states:
"The destination shorthand field of the ICR allows the delivery mode to be
by-passed in favor of broadcasting the IPI to all the processors on the
system bus and/or back to itself (see Section 10.6.1, Interrupt Command
Register (ICR)). Three destination shorthands are

To support IPI shorthands wrap invocations of apic->send_IPI_allbutself()
in a helper function, so the static key controlling the shorthand mode is
only in one place.

If the APIC was already enabled on entry of setup_local_APIC() then
disabling it soft via the SPIV register makes a lot of sense.
That masks all LVT entries and brings it into a well defined state.
Otherwise previously enabled LVTs which are not touched in the setup
function stay unmasked and
Nadav noticed that the cpumask allocations in native_send_call_func_ipi()
are noticeable in microbenchmarks.
Use the new cpumask_or_equal() function to simplify the decision whether
the supplied target CPU mask is either equal to cpu_online_mask or equal to
cpu_online_mask except for the CPU on
The IPI shorthand functionality delivers IPI/NMI broadcasts to all CPUs in
the system. This can have similar side effects as the MCE broadcasting when
CPUs are waiting in the BIOS or are offlined.
The kernel tracks already the state of offlined CPUs whether they have been
brought up at least once
All callers of apic->send_IPI_all() and apic->send_IPI_allbutself() contain
the decision logic for shorthand invocation already and invoke
send_IPI_mask() if the prereqisites are not satisfied.
Implement shorthand support for x2apic.

V2: Remove the decision
The IPI code of x86 needs to evaluate whether the target cpumask is equal
to the cpu_online_mask or equal except for the calling CPU.
To replace the current implementation which requires the usage of a
temporary cpumask, which might involve allocations, add a new function
which compares a cpumask

Remove the now redundant decision logic in the APIC code and the duplicate
helper in probe_64.c.
If the APIC is soft disabled then unmasking an LVT entry does not work and
the write is ignored. perf_events_lapic_init() tries to do so.
Move the invocation after the point where the APIC has been enabled.

In order to support IPI/NMI broadcasting via the shorthand mechanism side
effects of shorthands need to be mitigated:
Shorthand IPIs and NMIs hit all CPUs including unplugged CPUs
Neither of those can be handled on unplugged CPUs for obvious reasons.
It would be trivial to just fully disable
For the upcoming shorthand support for all APIC incarnations the command
line option needs to be available for 64 bit as well.
While at it, rename the control variable, make it static and mark it
__ro_after_init.

The booted once information which is required to deal with the MCE
broadcast issue on X86 correctly is stored in the per cpu hotplug state,
which is perfectly fine for the intended purpose.
X86 needs that information for supporting NMI broadcasting via shortcuts,
but retrieving it from per cpu
Move it where it belongs. That allows to keep all the shorthand logic in
one place.
