Merge usb-serial updates from Johan:
USB-serial updates for 6.14-rc1
Here are the USB-serial updates for 6.14-rc1, including:
- fix a long-standing NULL-deref issue in quatech2
- add support for hardware flow control to ch341
Included is also a related clean up.
All have been in linux-next with no reported issues.

There are too many different host behaviors when it comes to NoStream
handling, and not everyone follows the USB and xHCI spec. The DWC3
driver attempts to do some guess work to interop with different hosts,
but it can't cover everything. Let's keep it simple and treat every host
the same: just retry on NoStream after a 100ms of no response delay.
Note that some hosts cannot handle frequent retries. This may affect
performance on certain defective hosts, but NoStream is a rare
occurrence and interoperability is more important.

Replace ternary (condition ? "enable" : "disable") syntax with helpers
from string_choices.h because:
1. Simple function call with one argument is easier to read. Ternary
operator has three arguments and with wrapping might lead to quite
long code.
2. Is slightly shorter thus also easier to read.
3. It brings uniformity in the text - same string.
4. Allows deduping by the linker, which results in a smaller binary

thunderbolt: Log config space when invalid config space reply is received
thunderbolt: Drop doubled empty line from ctl.h
thunderbolt: debugfs: Add write capability to path config space
This patch addresses a null-ptr-deref in qt2_process_read_urb() due to
an incorrect bounds check in the following:
if (newport > serial->num_ports) {
dev_err(&port->dev,
"%s - port change to invalid port: %i\n",
__func__, newport);
break;
}
The condition doesn't account for the valid range of the serial->port
buffer, which is from 0 to serial->num_ports - 1. When newport is equal
to serial->num_ports, the assignment of "port" in the
following code is out-of-bounds and NULL:
serial_priv->current_port = newport;
port = serial->port[serial_priv->current_port];
The fix checks if newport is greater than or equal to serial->num_ports
indicating it is out-of-bounds.

The new __kvm_faultin_pfn() function is upset by the fact that e500
KVM ignores host page permissions - __kvm_faultin requires a "writable"
outgoing argument, but e500 KVM is passing NULL.
While a simple fix would be possible that simply allows writable to
be NULL, it is quite ugly to have e500 KVM ignore completely the host
permissions and map readonly host pages as guest-writable. Merge a more
complete fix and remove the VMA-based attempts at building huge shadow TLB
entries. Using a PTE lookup, similar to what is done for x86, is better
and works with remap_pfn_range() because it does not assume that VM_PFNMAP
areas are contiguous. Note that the same incorrect logic is there in
ARM's get_vma_page_shift() and RISC-V's kvm_riscv_gstage_ioremap().
Fortunately, for e500 most of the code is already there; it just has to
be changed to compute the range from find_linux_pte()'s output rather
than find_vma(). The new code works for both VM_PFNMAP and hugetlb
mappings, so the latter is removed.
Patches 2-5 were tested by the reporter, Christian Zigotzky. Since
the difference with v1 is minimal, I am going to send it to Linus
today.
e500 KVM tries to bypass __kvm_faultin_pfn() in order to map VM_PFNMAP
VMAs as huge pages. This is a Bad Idea because VM_PFNMAP VMAs could
become noncontiguous as a result of callsto remap_pfn_range().
Instead, use the already existing host PTE lookup to retrieve a
valid host-side mapping level after __kvm_faultin_pfn() has
returned. Then find the largest size that will satisfy the
guest's request while staying within a single host PTE.

Add the possibility of marking a page so that the UW and SW bits are

Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
kvmppc_e500_ref_setup is returning whether the guest TLB entry is writable,
which is than passed to kvm_release_faultin_page. This makes little sense
for two reasons: first, because the function sets up the private data for
the page and the return value feels like it has been bolted on the side;
second, because what really matters is whether the _shadow_ TLB entry is
writable. If it is not writable, the page can be released as non-dirty.
Shift from using tlbe_is_writable(gtlbe) to doing the same check on
the shadow TLB entry.

If find_linux_pte fails, IRQs will not be restored. This is unlikely

When inserting a USB device, examining hcd->rsrc_start can be
helpful in identifying which hcd is mounted, as the physical
address represented here is typically unique.
The following code snippet demonstrates this:
struct usb_hcd *hcd = bus_to_hcd(udev->bus);
unsigned long long usb_hcd_addr = (unsigned long long)hcd->rsrc_start;
However, this approach has limitations now. For USB hosts with an
MMIO interface, the effectiveness of this method is restricted to
USB 2.0.
Because commit 3429e91a66 ("usb: host: xhci: add platform driver
support") assigned res->start to hcd->rsrc_start. But
shared_hcd->rsrc_start remains unassigned, which is also necessary
in certain scenarios.

When the system begins to enter suspend mode, dwc3_suspend() is called
by PM suspend. There is a problem that if someone interrupt the system
suspend process between dwc3_suspend() and pm_suspend() of its parent
device, PM suspend will be canceled and attempt to resume suspended
devices so that dwc3_resume() will be called. However, dwc3 and its
parent device (like the power domain or glue driver) may already be
suspended by runtime PM in fact. If this sutiation happened, the
pm_runtime_set_active() in dwc3_resume() will return an error since
parent device was suspended. This can lead to unexpected behavior if
DWC3 proceeds to execute dwc3_resume_common().
EX.
RPM suspend: ... -> dwc3_runtime_suspend()
-> rpm_suspend() of parent device
...
PM suspend: ... -> dwc3_suspend() -> pm_suspend of parent device
^ interrupt, so resume suspended device
... <- dwc3_resume() <-/
^ pm_runtime_set_active() returns error
To prevent the problem, this commit will skip dwc3_resume_common() and
return the error if pm_runtime_set_active() fails.

In some cases, when password2 becomes the working password, the
client swaps the two password fields in the root session struct, but
not in the smb3_fs_context struct in cifs_sb. DFS automounts inherit
fs context from their parent mounts. Therefore, they might end up
getting the passwords in the stale order.
The automount should succeed, because the mount function will end up
retrying with the actual password anyway. But to reduce these
unnecessary session setup retries for automounts, we can sync the
parent context's passwords with the root session's passwords before
duplicating it to the child's fs context.

Pull sched_ext fixes from Tejun Heo:
- Fix corner case bug where ops.dispatch() couldn't extend the
execution of the current task if SCX_OPS_ENQ_LAST is set.
- Fix ops.cpu_release() not being called when a SCX task is preempted
by a higher priority sched class task.
- Fix buitin idle mask being incorrectly left as busy after an idle CPU
is picked and kicked.
- scx_ops_bypass() was unnecessarily using rq_lock() which comes with
rq pinning related sanity checks which could trigger spuriously.
Switch to raw_spin_rq_lock().
