Linus Torvalds ebf435d3b5 IIO / Staging driver update for 5.15-rc1
Here is the big set of staging and IIO driver updates for 5.15-rc1.
 Also included in here are the counter driver subsystem updates as the
 IIO drivers needed them.
 
 Lots of churn in some staging drivers, we dropped the "old" rtl8188eu
 driver and replaced it with a newer version of the driver that had been
 maintained out-of-tree by Larry with the end goal of actually being able
 to get this driver out of staging eventually.  Despite that driver being
 "newer" the line count of this pull request is going up.
 
 Some drivers moved out of staging as well, which is always nice to see,
 that is why there are additions to the mfc and misc driver subsystems.
 All of these were acked by the various subsystem maintainers involved.
 
 But by far, as normal, it's coding style cleanups all over the
 drivers/staging/ tree in here.
 
 Full details of these changes are in the shortlog.
 
 All of these have been in linux-next for a while with no reported
 problems.

[ Note: the r8188eu merge clashed with commit 89939e8906 ("staging:
  rtlwifi: use siocdevprivate") from the networking tree. When resolving
  the issue, I noted that the whole r8188eu rtw_android code is dead
  since commit ae7471cae0 ("staging: r8188eu: remove rtw_ioctl
  function").

  End result: the merge resolution was to throw all of that away,
  rather than do the mindless fixup to code that isn't actually
  reachable                                               - Linus ]

Linus Torvalds c6c3c5704b Driver core update for 5.15-rc1
Here is the big set of driver core patches for 5.15-rc1.
 
 These do change a number of different things across different
 subsystems, and because of that, there were 2 stable tags created that
 might have already come into your tree from different pulls that did the
 following
 	- changed the bus remove callback to return void
 	- sysfs iomem_get_mapping rework
 
 The latter one will cause a tiny merge issue with your tree, as there
 was a last-minute fix for this in 5.14 in your tree, but the fixup
 should be "obvious".  If you want me to provide a fixed merge for this,
 please let me know.
 
 Other than those two things, there's only a few small things in here:
 	- kernfs performance improvements for huge numbers of sysfs
 	  users at once
 	- tiny api cleanups
 	- other minor changes
 
 All of these have been in linux-next for a while with no reported
 problems, other than the before-mentioned merge issue.

Linus Torvalds e5e726f7bb Updates for locking and atomics:
The regular pile:
 
   - A few improvements to the mutex code
 
   - Documentation updates for atomics to clarify the difference between
     cmpxchg() and try_cmpxchg() and to explain the forward progress
     expectations.
 
   - Simplification of the atomics fallback generator
 
   - The addition of arch_atomic_long*() variants and generic arch_*()
     bitops based on them.
 
   - Add the missing might_sleep() invocations to the down*() operations of
     semaphores.
 
 The PREEMPT_RT locking core:
 
   - Scheduler updates to support the state preserving mechanism for
     'sleeping' spin- and rwlocks on RT. This mechanism is carefully
     preserving the state of the task when blocking on a 'sleeping' spin- or
     rwlock and takes regular wake-ups targeted at the same task into
     account. The preserved or updated (via a regular wakeup) state is
     restored when the lock has been acquired.
 
   - Restructuring of the rtmutex code so it can be utilized and extended
     for the RT specific lock variants.
 
   - Restructuring of the ww_mutex code to allow sharing of the ww_mutex
     specific functionality for rtmutex based ww_mutexes.
 
   - Header file disentangling to allow substitution of the regular lock
     implementations with the PREEMPT_RT variants without creating an
     unmaintainable #ifdef mess.
 
   - Shared base code for the PREEMPT_RT specific rw_semaphore and rwlock
     implementations. Contrary to the regular rw_semaphores and rwlocks the
     PREEMPT_RT implementation is writer unfair because it is infeasible to
     do priority inheritance on multiple readers. Experience over the years
     has shown that real-time workloads are not the typical workloads which
     are sensitive to writer starvation. The alternative solution would be
     to allow only a single reader which has been tried and discarded as it
     is a major bottleneck especially for mmap_sem. Aside of that many of
     the writer starvation critical usage sites have been converted to a
     writer side mutex/spinlock and RCU read side protections in the past
     decade so that the issue is less prominent than it used to be.
 
   - The actual rtmutex based lock substitutions for PREEMPT_RT enabled
     kernels which affect mutex, ww_mutex, rw_semaphore, spinlock_t and
     rwlock_t. The spin/rw_lock*() functions disable migration across the
     critical section to preserve the existing semantics vs. per CPU
     variables.
 
   - Rework of the futex REQUEUE_PI mechanism to handle the case of early
     wake-ups which interleave with a re-queue operation to prevent the
     situation that a task would be blocked on both the rtmutex associated
     to the outer futex and the rtmutex based hash bucket spinlock.
 
     While this situation cannot happen on !RT enabled kernels the changes
     make the underlying concurrency problems easier to understand in
     general. As a result the difference between !RT and RT kernels is
     reduced to the handling of waiting for the critical section. !RT
     kernels simply spin-wait as before and RT kernels utilize rcu_wait().
 
   - The substitution of local_lock for PREEMPT_RT with a spinlock which
     protects the critical section while staying preemptible. The CPU
     locality is established by disabling migration.
 
   The underlying concepts of this code have been in use in PREEMPT_RT for
   way more than a decade. The code has been refactored several times over
   the years and this final incarnation has been optimized once again to be
   as non-intrusive as possible, i.e. the RT specific parts are mostly
   isolated.
 
   It has been extensively tested in the 5.14-rt patch series and it has
   been verified that !RT kernels are not affected by these changes.

Michael Straube f7766f1b00 staging: r8188eu: remove ethernet.h header file
There are only two definitions from ethernet.h used in the driver.
Namely:

#define ETHERNET_HEADER_SIZE           14      /*  Ethernet Header Length */
#define LLC_HEADER_SIZE                6       /*  LLC Header Length */

Both are only used in the file core/rtw_recv.c. Replace the usage of
ETHERNET_HEADER_SIZE with ETH_HLEN, move the definition of LLC_HEADER_SIZE
into rtw_recv.h and remove the now unused ethernet.h header file.
