UPSTREAM: USB: gadget: core: create sysfs link between udc and gadget
udc device and gadget device are tightly coupled, yet there's no good way to corelate the two. Add a sysfs link in udc that points to the corresponding gadget device. An example use case: userspace configures a f_midi configfs driver and bind the udc device, then it tries to locate the corresponding midi device, which is a child device of the gadget device. The gadget device that's associated to the udc device has to be identified in order to index the midi device. Having a sysfs link would make things much easier.

ANDROID: binder: fix KMI-break due to alloc->lock
Wrap 'struct binder_proc' inside 'struct binder_proc_wrap' to add the
alloc->lock equivalent without breaking the KMI. Also, add convenient
apis to access/modify this new spinlock.
Without this patch, the following KMI issues show up:
type 'struct binder_proc' changed
byte size changed from 616 to 576
type 'struct binder_alloc' changed
byte size changed from 152 to 112
member 'spinlock_t lock' was added
member 'struct mutex mutex' was removed

ANDROID: binder: fix KMI-break due to address type change
In commit ("binder: keep vma addresses type as unsigned long") the vma
address type in 'struct binder_alloc' and 'struct binder_buffer' is
changed from 'void __user *' to 'unsigned long'.
This triggers the following KMI issues:
type 'struct binder_buffer' changed
member changed from 'void* user_data' to 'unsigned long user_data'
type changed from 'void*' to 'unsigned long'
type 'struct binder_alloc' changed
member changed from 'void* buffer' to 'unsigned long buffer'
type changed from 'void*' to 'unsigned long'
This offending commit is being backported as part of a larger patchset
from upstream in [1]. Lets fix these issues by doing a partial revert
that restores the original types and casts to an integer type where
necessary.
Note this approach is preferred over dropping the single KMI-breaking
patch from the backport, as this would have created non-trivial merge
conflicts in the subsequent cherry-picks.

UPSTREAM: binder: switch alloc->mutex to spinlock_t
The alloc->mutex is a highly contended lock that causes performance issues on Android devices. When a low-priority task is given this lock and it sleeps, it becomes difficult for the task to wake up and complete its work. This delays other tasks that are also waiting on the mutex. The problem gets worse when there is memory pressure in the system, because this increases the contention on the alloc->mutex while the shrinker reclaims binder pages. Switching to a spinlock helps to keep the waiters running and avoids the overhead of waking up tasks. This significantly improves the transaction latency when the problematic scenario occurs. The performance impact of this patchset was measured by stress-testing the binder alloc contention. In this test, several clients of different priorities send thousands of transactions of different sizes to a single server. In parallel, pages get reclaimed using the shinker's debugfs. The test was run on a Pixel 8, Pixel 6 and qemu machine. The results were similar on all three devices: after: | sched | prio | average | max | min | |--------+------+---------+-----------+---------| | fifo | 99 | 0.135ms | 1.197ms | 0.022ms | | fifo | 01 | 0.136ms | 5.232ms | 0.018ms | | other | -20 | 0.180ms | 7.403ms | 0.019ms | | other | 19 | 0.241ms | 58.094ms | 0.018ms | before: | sched | prio | average | max | min | |--------+------+---------+-----------+---------| | fifo | 99 | 0.350ms | 248.730ms | 0.020ms | | fifo | 01 | 0.357ms | 248.817ms | 0.024ms | | other | -20 | 0.399ms | 249.906ms | 0.020ms | | other | 19 | 0.477ms | 297.756ms | 0.022ms | The key metrics above are the average and max latencies (wall time). These improvements should roughly translate to p95-p99 latencies on real workloads. The response time is up to 200x faster in these scenarios and there is no penalty in the regular path. Note that it is only possible to convert this lock after a series of changes made by previous patches. These mainly include refactoring the sections that might_sleep() and changing the locking order with the mmap_lock amongst others.

UPSTREAM: binder: reverse locking order in shrinker callback
The locking order currently requires the alloc->mutex to be acquired first followed by the mmap lock. However, the alloc->mutex is converted into a spinlock in subsequent commits so the order needs to be reversed to avoid nesting the sleeping mmap lock under the spinlock. The shrinker's callback binder_alloc_free_page() is the only place that needs to be reordered since other functions have been refactored and no longer nest these locks. Some minor cosmetic changes are also included in this patch.

UPSTREAM: binder: document the final page calculation
The code to determine the page range for binder_lru_freelist_del() is quite obscure. It leverages the buffer_size calculated before doing an oversized buffer split. This is used to figure out if the last page is being shared with another active buffer. If so, the page gets trimmed out of the range as it has been previously removed from the freelist. This would be equivalent to getting the start page of the next in-use buffer explicitly. However, the code for this is much larger as we can see in binder_free_buf_locked() routine. Instead, lets settle on documenting the tricky step and using better names for now. I believe an ideal solution would be to count the binder_page->users to determine when a page should be added or removed from the freelist. However, this is a much bigger change than what I'm willing to risk at this time.

UPSTREAM: binder: keep vma addresses type as unsigned long
The vma addresses in binder are currently stored as void __user *. This requires casting back and forth between the mm/ api which uses unsigned long. Since we also do internal arithmetic on these addresses we end up having to cast them _again_ to an integer type. Lets stop all the unnecessary casting which kills code readability and store the virtual addresses as the native unsigned long from mm/. Note that this approach is preferred over uintptr_t as Linus explains in [1]. Opportunistically add a few cosmetic touchups.

UPSTREAM: selftests: timers: Fix valid-adjtimex signed left-shift undefined behavior
[ Upstream commit 076361362122a6d8a4c45f172ced5576b2d4a50d ]
The struct adjtimex freq field takes a signed value who's units are in
shifted (<<16) parts-per-million.
Unfortunately for negative adjustments, the straightforward use of:
freq = ppm << 16 trips undefined behavior warnings with clang:
valid-adjtimex.c:66:6: warning: shifting a negative signed value is undefined [-Wshift-negative-value]
-499<<16,
~~~~^
valid-adjtimex.c:67:6: warning: shifting a negative signed value is undefined [-Wshift-negative-value]
-450<<16,
~~~~^
..
Fix it by using a multiply by (1 << 16) instead of shifting negative values
in the valid-adjtimex test case. Align the values for better readability.

BACKPORT: FROMGIT: module: allow UNUSED_KSYMS_WHITELIST to be relative against objtree.
If UNUSED_KSYMS_WHITELIST is a file generated before Kbuild runs, and the source tree is in a read-only filesystem, the developer must put the file somewhere and specify an absolute path to UNUSED_KSYMS_WHITELIST. This worked, but if IKCONFIG=y, an absolute path is embedded into .config and eventually into vmlinux, causing the build to be less reproducible when building on a different machine. This patch makes the handling of UNUSED_KSYMS_WHITELIST to be similar to MODULE_SIG_KEY. First, check if UNUSED_KSYMS_WHITELIST is an absolute path, just as before this patch. If so, use the path as is. If it is a relative path, use wildcard to check the existence of the file below objtree first. If it does not exist, fall back to the original behavior of adding $(srctree)/ before the value. After this patch, the developer can put the generated file in objtree, then use a relative path against objtree in .config, eradicating any absolute paths that may be evaluated differently on different machines.
