USB: fixes for v5.3-rc4
Just a three fixes this time around.
A race condition on mass storage gadget between disable() and
set_alt()
Clear a flag that was left set upon reset or disconnect
A fix for renesas_usb3 UDC's sysfs interface
* tag 'fixes-for-v5.3-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb:
usb: gadget: mass_storage: Fix races between fsg_disable and fsg_set_alt
usb: gadget: composite: Clear "suspended" on reset/disconnect
usb: gadget: udc: renesas_usb3: Fix sysfs interface of "role"
Currently, failure of cpuhp_setup_state() is ignored and the syscore ops
and the control interfaces can still be added even after the failure. But,
this error handling will cause a few issues:
1. The CPUs may have different values in the IA32_UMWAIT_CONTROL
MSR because there is no way to roll back the control MSR on
the CPUs which already set the MSR before the failure.
2. If the sysfs interface is added successfully, there will be a mismatch
between the global control value and the control MSR:
- The interface shows the default global control value. But,
the control MSR is not set to the value because the CPU online
function, which is supposed to set the MSR to the value,
is not installed.
- If the sysadmin changes the global control value through
the interface, the control MSR on all current online CPUs is
set to the new value. But, the control MSR on newly onlined CPUs
after the value change will not be set to the new value due to
lack of the CPU online function.
3. On resume from suspend/hibernation, the boot CPU restores the control
MSR to the global control value through the syscore ops. But, the
control MSR on all APs is not set due to lake of the CPU online
function.
To solve the issues and enforce consistent behavior on the failure
of the CPU hotplug setup, make the following changes:
1. Cache the original control MSR value which is configured by
hardware or BIOS before kernel boot. This value is likely to
be 0. But it could be a different number as well. Cache the
control MSR only once before the MSR is changed.
2. Add the CPU offline function so that the MSR is restored to the
original control value on all CPUs on the failure.
3. On the failure, exit from cpumait_init() so that the syscore ops
and the control interfaces are not added.

One of the modifications made by commit d916b1be94 ("nvme-pci: use
host managed power state for suspend") was adding a pci_save_state()
call to nvme_suspend() so as to instruct the PCI bus type to leave
devices handled by the nvme driver in D0 during suspend-to-idle.
That was done with the assumption that ASPM would transition the
device's PCIe link into a low-power state when the device became
inactive. However, if ASPM is disabled for the device, its PCIe
link will stay in L0 and in that case commit d916b1be94 is likely
to cause the energy used by the system while suspended to increase.
Namely, if the device in question works in accordance with the PCIe
specification, putting it into D3hot causes its PCIe link to go to
L1 or L2/L3 Ready, which is lower-power than L0. Since the energy
used by the system while suspended depends on the state of its PCIe
link (as a general rule, the lower-power the state of the link, the
less energy the system will use), putting the device into D3hot
during suspend-to-idle should be more energy-efficient that leaving
it in D0 with disabled ASPM.
For this reason, avoid leaving NVMe devices with disabled ASPM in D0
during suspend-to-idle. Instead, shut them down entirely and let
the PCI bus type put them into D3.

The PQs of internal H/W queues (QMANs) can be located in different memory
areas for different ASICs. Therefore, when writing PQEs, we need to use
the correct function according to the location of the PQ. e.g. if the PQ
is located in the device's memory (SRAM or DRAM), we need to use
memcpy_toio() so it would work in architectures that have separate
address ranges for IO memory.
This patch makes the code that writes the PQE to be ASIC-specific so we
can handle this properly per ASIC.

If fsg_disable() and fsg_set_alt() are called too closely to each
other (for example due to a quick reset/reconnect), what can happen
is that fsg_set_alt sets common->new_fsg from an interrupt while
handle_exception is trying to process the config change caused by
fsg_disable():
fsg_disable()
...
handle_exception()
sets state back to FSG_STATE_NORMAL
hasn't yet called do_set_interface()
or is inside it.
---> interrupt
fsg_set_alt
sets common->new_fsg
queues a new FSG_STATE_CONFIG_CHANGE
<---
Now, the first handle_exception can "see" the updated
new_fsg, treats it as if it was a fsg_set_alt() response,
call usb_composite_setup_continue() etc...
But then, the thread sees the second FSG_STATE_CONFIG_CHANGE,
and goes back down the same path, wipes and reattaches a now
active fsg, and .. calls usb_composite_setup_continue() which
at this point is wrong.
Not only we get a backtrace, but I suspect the second set_interface
wrecks some state causing the host to get upset in my case.
This fixes it by replacing "new_fsg" by a "state argument" (same
principle) which is set in the same lock section as the state
update, and retrieved similarly.
That way, there is never any discrepancy between the dequeued
state and the observed value of it. We keep the ability to have
the latest reconfig operation take precedence, but we guarantee
that once "dequeued" the argument (new_fsg) will not be clobbered
by any new event.

- Convert the RISC-V standard clocksource away from per-cpu data
structures, since only one is used by Linux, even on a multi-CPU
system
- A set of DT binding updates that remove an obsolete text binding in
favor of a YAML binding, fix a bogus compatible string in the
schema (thus fixing a "make dtbs_check" warning), and clarifies the
future values expected in one of the RISC-V CPU properties"

Pull x86 fixes from Thomas Gleixner:
"A few fixes for x86:
- Don't reset the carefully adjusted build flags for the purgatory
and remove the unwanted flags instead. The 'reset all' approach led
to build fails under certain circumstances.
- Unbreak CLANG build of the purgatory by avoiding the builtin
memcpy/memset implementations.
- Address missing prototype warnings by including the proper header
- Fix yet more fall-through issues"

"A small fix for the affinity spreading code.
It failed to handle situations where a single vector was requested
either due to only one CPU being available or vector exhaustion

A compilation -Wimplicit-fallthrough warning was enabled by commit
a035d552a9 ("Makefile: Globally enable fall-through warning")
Even though clang 10.0.0 does not currently support this warning without
a patch, clang currently does not support a value for this option.
Link: https://bugs.llvm.org/show_bug.cgi?id=39382
The gcc default for this warning is 3 so removing the =3 has no effect
for gcc and enables the warning for patched versions of clang.
Also remove the =3 from an existing use in a parisc Makefile:

Here are some small char/misc driver fixes for 5.3-rc4.
Two of these are for the habanalabs driver for issues found when running
on a big-endian system (are they still alive?) The others are tiny
fixes reported by people, and a MAINTAINERS update about the location of
the fpga development tree.
All of these have been in linux-next for a while with no reported
issues.

Here are 2 small fixes for some driver core issues that have been
reported. There is also a kernfs "fix" here, which was then reverted
because it was found to cause problems in linux-next.
The driver core fixes both resolve reported issues, one with gpioint
stuff that showed up in 5.3-rc1, and the other finally (and hopefully)
resolves a very long standing race when removing glue directories. It's
nice to get that issue finally resolved and the developers involved
should be applauded for the persistence it took to get this patch
finally accepted.
All of these have been in linux-next for a while with no reported
issues. Well, the one reported issue, hence the revert :)

Here is a single tty kgdb fix for 5.3-rc4.
It fixes an annoying log message that has caused kdb to become useless.
It's another fallout from ddde3c18b7 ("vt: More locking checks") which
tries to enforce locking checks more strictly in the tty layer,
unfortunatly when kdb is stopped, there's no need for locks :)

Here are some small USB fixes for 5.3-rc4.
The "biggest" one here is moving code from one file to another in order
to fix a long-standing race condition with the creation of sysfs files
for USB devices. Turns out that there are now userspace tools out there
that are hitting this long-known bug, so it's time to fix them.
Thankfully the tool-maker in this case fixed the issue :)
The other patches in here are all fixes for reported issues. Now that
syzbot knows how to fuzz USB drivers better, and is starting to now fuzz
the userspace facing side of them at the same time, there will be more
and more small fixes like these coming, which is a good thing.
