When we release a regulator we need to remove references to it from the
rdev which means locking the rdev. Currently we also free resources
associated with the regulator inside the rdev lock but there is no need
to do this, we can reduce the region the lock is held by restricting it
to just actions that affect the rdev.

Enable CONFIG_JUMP_LABEL in the defconfigs, the feature already deals with
GCC not having the asm-goto feature so will not break the build on
older compilers.
Having it enabled generates a faster kernel at very little extra cost
since we already include all the code patching code by having KPROBES
enabled.

The qrwlock implementation is slightly heavy in its use of memory
barriers, mainly through the use of _cmpxchg() and _return() atomics, which
imply full barrier semantics.
This patch modifies the qrwlock code to use the more relaxed atomic
routines so that we can reduce the unnecessary barrier overhead on
weakly-ordered architectures.

Whilst porting the generic qrwlock code over to arm64, it became
apparent that any portable locking code needs finer-grained control of
the memory-ordering guarantees provided by our atomic routines.
In particular: xchg, cmpxchg, {add,sub}_return are often used in
situations where full barrier semantics (currently the only option
available) are not required. For example, when a reader increments a
reader count to obtain a lock, checking the old value to see if a writer
was present, only acquire semantics are strictly needed.
This patch introduces three new ordering semantics for these operations:
- *_relaxed: No ordering guarantees. This is similar to what we have
already for the non-return atomics (e.g. atomic_add).
- *_acquire: ACQUIRE semantics, similar to smp_load_acquire.
- *_release: RELEASE semantics, similar to smp_store_release.
In memory-ordering speak, this means that the acquire/release semantics
are RCpc as opposed to RCsc. Consequently a RELEASE followed by an
ACQUIRE does not imply a full barrier, as already documented in
memory-barriers.txt.
Currently, all the new macros are conditionally mapped to the full-mb
variants, however if the *_relaxed version is provided by the
architecture, then the acquire/release variants are constructed by
supplementing the relaxed routine with an explicit barrier.

The kernel build bot showed a new warning triggered by commit:
76695af20c ("locking, arch: use WRITE_ONCE()/READ_ONCE() in smp_store_release()/smp_load_acquire()")
because Sparse does not like WRITE_ONCE() accessing elements
from the (sparse) RCU address space:
fs/afs/inode.c:448:9: sparse: incorrect type in initializer (different address spaces)
fs/afs/inode.c:448:9: expected struct afs_permits *__val
fs/afs/inode.c:448:9: got void [noderef] <asn:4>*<noident>
Solution is to force cast away the sparse attributes for the initializer
of the union in WRITE_ONCE().
(And as this now gets too long, also split the macro into multiple lines.)

A question [1] was raised about the use of page::private in AUX buffer
allocations, so let's add a clarification about its intended use.
The private field and flag are used by perf's rb_alloc_aux() path to
tell the pmu driver the size of each high-order allocation, so that the
driver can program those appropriately into its hardware. This only
matters for PMUs that don't support hardware scatter tables. Otherwise,
every page in the buffer is just a page.
This patch adds a comment about the private field to the AUX buffer
allocation path.

Add a cell for the usb power_supply part of the axp20x PMICs.
Note that this cell is only for the usb power_supply part and not the
ac-power / battery-charger / rtc-backup-bat-charger bits.
Depending on the board each of those must be enabled / disabled separately
in devicetree as most boards do not use all 4. So in dt each one needs its
own child-node of the axp20x node. Another reason for using separate child
nodes for each is so that other devicetree nodes can have a power-supply
property with a phandle referencing a node representing a single
power-supply.
The decision to use a separate devicetree node for each is reflected on
the kernel side by each getting its own mfd-cell / platform_device and
platform-driver.
Note this commit also makes some whitespace changes to the intialization
of existing cells in axp20x_cells, these are pure whitespace changes,
functionally nothing changes.
