There are three out of many Intel platforms that are using TLAs

By removing the goto 'cleanup' statement, and replacing it with 'continue',
'break' and 'return', helps simplify the code and further showcase in which
case the while loop iterates.
This change prepares for the comprehensive handle_tx_event() rework.

Simplifying the handle_tx_event() function by addressing the complexity
of its while loop. Replaces specific 'goto cleanup' statements with
'return' statements, applicable only where 'ep->skip' is set to 'false',
ensuring loop termination.
The original while loop, combined with 'goto cleanup', adds unnecessary
complexity. This change aims to untangle the loop's logic, facilitating a
more straightforward review of the upcoming comprehensive rework.

When handle_tx_event() encounters a COMP_MISSED_SERVICE_ERROR or
COMP_NO_PING_RESPONSE_ERROR event, it moves to 'goto cleanup'.
Here, it sets a flag, 'handling_skipped_tds', based on conditions that
exclude these two error events.
Subsequently, the process evaluates the loop that persists as long as
'handling_skipped_tds' remains true. However, since 'trb_comp_code' does
not change after its assignment, if it indicates either of the two error
conditions, the loop terminates immediately.
To simplify this process and enhance clarity, the modification involves
returning immediately upon detecting COMP_MISSED_SERVICE_ERROR or
COMP_NO_PING_RESPONSE_ERROR. This adjustment allows for the direct use of
'ep->skip', removing the necessity for the 'handling_skipped_tds' flag.

events without TRB
Some transfer events don't always point to a TRB, and consequently don't
have a endpoint ring. In these cases, function handle_tx_event() should
not proceed, because if 'ep->skip' is set, the pointer to the endpoint
ring is used.
To prevent a potential failure and make the code logical, return after
checking the completion code for a Transfer event without TRBs.

If this quirk was set then driver would treat transfer events with
'Success' completion code as 'Short packet' if there were untransferred
bytes left.
This is so common that turn it into default behavior.
xhci_warn_ratelimited() is no longer used after this, so remove it.
A success event with untransferred bytes left doesn't always mean a
misbehaving controller. If there was an error mid a multi-TRB TD it's
allowed to issue a success event for the last TRB in that TD.
See xhci 1.2 spec 4.9.1 Transfer Descriptors
"Note: If an error is detected while processing a multi-TRB TD, the xHC
shall generate a Transfer Event for the TRB that the error was detected
on with the appropriate error Condition Code, then may advance to the
next TD. If in the process of advancing to the next TD, a Transfer TRB
is encountered with its IOC flag set, then the Condition Code of the
Transfer Event generated for that Transfer TRB should be Success,
because there was no error actually associated with the TRB that
generated the Event. However, an xHC implementation may redundantly
assert the original error Condition Code."

Replace size_mul() with array_size() in memory allocation and freeing
processes, it fits better semantically.
Macro array_size() is identical to size_mult(), which clamps the max size,
so it's imperative that array_size() is used when freeing said memory.

'erst_size' represents the maximum capacity of entries that ERST can hold,
while 'num_entries' indicates the actual number of entries currently held
in the ERST. These two values are identical because the xhci driver does
not support ERST expansion. Thus, 'erst_size' is removed.

Reduce the number of do-while loops by 1. The number of loops should be
number of segment + 1, the +1 is in case deq and enq are on the same
segment. But due to the use of a do-while loop, the expression is
evaluated after executing the loop, thus the loop is executed 1 extra
time.
Changing the do-while loop expression from "<=" to "<", reduces the loop
amount by 1. The expression "<=" would also work if it was a while loop
instead of a do-while loop.

Address debug message inaccuracies in xhci_ring_expansion_needed().
Specifically, remove the portion of the debug message that indicates the
number of enqueue TRBs to be added to the dequeue segment. This part of
the message may mislead and the calculated value is incorrect. Given that
this value is not of significant importance and the statement is not
consistently accurate, it has been omitted.
The specific issues with the debug message that this commit resolves:
- The calculation of the number of TRBs is incorrect. The current
calculation erroneously includes the link TRB, which is reserved.
Furthermore, the calculated number of TRBs can exceed the dequeue
segment, resulting in a misleading debug message.
- The current phrasing suggests that "ring expansion by X is needed,
adding X TRBs moves enqueue Y TRBs into the dequeue segment".
The intended message, however, is "IF the ring is NOT expanded by X,
THEN adding X TRBs moves enqueue Y TRBs into the dequeue segment".

Check if requested segments ('segs' or 'ERST_DEFAULT_SEGS') exceeds the
maximum amount ERST supports.
When 'segs' is '0', 'ERST_DEFAULT_SEGS' is used instead. But both values
may not exceed ERST max.
Macro 'ERST_MAX_SEGS' is renamed to 'ERST_DEFAULT_SEGS'. The new name
better represents the macros, which is the number of Event Ring segments
to allocate, when the amount is not specified.
Additionally, rename and change xhci_create_secondary_interrupter()'s
argument 'int num_segs' to 'unsigned int segs'. This makes it the same
as its counter part in xhci_alloc_interrupter().

Port capability flags for USB2 ports have been cached in an
u32 xhci->ext_caps[] array long before the driver had struct xhci_port
and struct xhci_port_cap structures.
Move these cached USB2 port capability values together with the other
port capability values into struct xhci_port_cap cability structure.
This also gets rid of the cumbersome way of mapping port to USB2
capability based on portnum as each port has a pointer to its capability
structure.

Currently the DWC3 driver supports only single port controller
which requires at least one HS PHY and at most one SS PHY.
But the DWC3 USB controller can be connected to multiple ports and
each port can have their own PHYs. Each port of the multiport
controller can either be HS+SS capable or HS only capable
Proper quantification of them is required to modify GUSB2PHYCFG
and GUSB3PIPECTL registers appropriately.
DWC3 multiport controllers are capable to service at most 15 High Speed
PHYs and 4 Supser Speed PHYs. Add support for detecting, obtaining and
configuring PHYs supported by a multiport controller.

Pull kvm fixes from Paolo Bonzini:
"This is a bit on the large side, mostly due to two changes:
- Changes to disable some broken PMU virtualization (see below for
details under "x86 PMU")
- Clean up SVM's enter/exit assembly code so that it can be compiled
without OBJECT_FILES_NON_STANDARD. This fixes a warning "Unpatched
return thunk in use. This should not happen!" when running KVM
selftests.
Everything else is small bugfixes and selftest changes:
- Fix a mostly benign bug in the gfn_to_pfn_cache infrastructure
where KVM would allow userspace to refresh the cache with a bogus
GPA. The bug has existed for quite some time, but was exposed by a
new sanity check added in 6.9 (to ensure a cache is either
GPA-based or HVA-based).
- Drop an unused param from gfn_to_pfn_cache_invalidate_start() that
got left behind during a 6.9 cleanup.
- Fix a math goof in x86's hugepage logic for
KVM_SET_MEMORY_ATTRIBUTES that results in an array overflow
(detected by KASAN).
- Fix a bug where KVM incorrectly clears root_role.direct when
userspace sets guest CPUID.
- Fix a dirty logging bug in the where KVM fails to write-protect
SPTEs used by a nested guest, if KVM is using Page-Modification
Logging and the nested hypervisor is NOT using EPT.
x86 PMU:
- Drop support for virtualizing adaptive PEBS, as KVM's
implementation is architecturally broken without an obvious/easy
path forward, and because exposing adaptive PEBS can leak host LBRs
to the guest, i.e. can leak host kernel addresses to the guest.
- Set the enable bits for general purpose counters in
PERF_GLOBAL_CTRL at RESET time, as done by both Intel and AMD
processors.
- Disable LBR virtualization on CPUs that don't support LBR
callstacks, as KVM unconditionally uses
PERF_SAMPLE_BRANCH_CALL_STACK when creating the perf event, and
would fail on such CPUs.
Tests:
- Fix a flaw in the max_guest_memory selftest that results in it
exhausting the supply of ucall structures when run with more than
256 vCPUs.
- Mark KVM_MEM_READONLY as supported for RISC-V in
set_memory_region_test"

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk fixes from Stephen Boyd:
"A couple clk driver fixes, a build fix, and a deadlock fix:
- Mediatek mt7988 has broken PCIe because the wrong parent is used
- Mediatek clk drivers may deadlock when registering their clks
because the clk provider device is repeatedly runtime PM resumed
and suspended during probe and clk registration.
Resuming the clk provider device deadlocks with an ABBA deadlock
due to genpd_lock and the clk prepare_lock. The fix is to keep the
device runtime resumed while registering clks.
- Another runtime PM related deadlock, this time with disabling
unused clks during late init.
We get an ABBA deadlock where a device is runtime PM resuming (or
suspending) while the disabling of unused clks is happening in
parallel. That runtime PM action calls into the clk framework and
tries to grab the clk prepare_lock while the disabling of unused
clks holds the prepare_lock and is waiting for that runtime PM
action to complete.
The fix is to runtime resume all the clk provider devices before
grabbing the clk prepare_lock during disable unused.
- A build fix to provide an empty devm_clk_rate_exclusive_get()
function when CONFIG_COMMON_CLK=n"
