Setting the SLEEP pin to its shutdown function for appropriate PMICs
doesn't need to happen in single-CPU context, so there's really no point
involving the syscore machinery. Hook it up to the standard driver model
shutdown method instead. This also obviates the issue that the syscore
ops weren't being unregistered on probe failure or module removal.Signed-off-by: Robin Murphy

The RK809/RK817 suspend/resume hooks should not have to depend on
whether this driver owns the pm_power_off hook, and thus the global
rk808_i2c_client is set - indeed, the GPIO-based control is really
only relevant when PSCI firmware is in charge of power rather than
the kernel. As driver model callbacks, they have an appropriate
device argument to hand, so can just always use that.Signed-off-by: Robin Murphy
Signed-off-by: Lee Jones -
With the device tree property "rockchip,system-power-controller" we
explicitly request to use this PMIC to power off the system. So always
register our poweroff function, even if some other handler (probably
PSCI poweroff) was registered before.This does tend to reveal a warning on shutdown due to the Rockchip I2C
driver not implementing an atomic transfer method, however since the
write to DEV_OFF takes effect immediately the I2C completion interrupt
is moot anyway, and as the very last thing written to the console it is
only visible to users going out of their way to capture serial output.Signed-off-by: Soeren Moch

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:struct foo {
int stuff;
struct boo array[];
};By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.Also, notice that, dynamic memory allocations won't be affected by
this change:"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]This issue was found with the help of Coccinelle.

Pull new zonefs file system from Damien Le Moal:
"Zonefs is a very simple file system exposing each zone of a zoned
block device as a file.Unlike a regular file system with native zoned block device support
(e.g. f2fs or the on-going btrfs effort), zonefs does not hide the
sequential write constraint of zoned block devices to the user. As a
result, zonefs is not a POSIX compliant file system. Its goal is to
simplify the implementation of zoned block devices support in
applications by replacing raw block device file accesses with a richer
file based API, avoiding relying on direct block device file ioctls
which may be more obscure to developers.One example of this approach is the implementation of LSM
(log-structured merge) tree structures (such as used in RocksDB and
LevelDB) on zoned block devices by allowing SSTables to be stored in a
zone file similarly to a regular file system rather than as a range of
sectors of a zoned device. The introduction of the higher level
construct "one file is one zone" can help reducing the amount of
changes needed in the application while at the same time allowing the
use of zoned block devices with various programming languages other
than C.Zonefs IO management implementation uses the new iomap generic code.
Zonefs has been successfully tested using a functional test suite
(available with zonefs userland format tool on github) and a prototype
implementation of LevelDB on top of zonefs"* tag 'zonefs-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/zonefs:

Pull x86 fixes from Thomas Gleixner:
"A set of fixes for X86:- Ensure that the PIT is set up when the local APIC is disable or
configured in legacy mode. This is caused by an ordering issue
introduced in the recent changes which skip PIT initialization when
the TSC and APIC frequencies are already known.- Handle malformed SRAT tables during early ACPI parsing which caused
an infinite loop anda boot hang.- Fix a long standing race in the affinity setting code which affects
PCI devices with non-maskable MSI interrupts. The problem is caused
by the non-atomic writes of the MSI address (destination APIC id)
and data (vector) fields which the device uses to construct the MSI
message. The non-atomic writes are mandated by PCI.If both fields change and the device raises an interrupt after
writing address and before writing data, then the MSI block
constructs a inconsistent message which causes interrupts to be
lost and subsequent malfunction of the device.The fix is to redirect the interrupt to the new vector on the
current CPU first and then switch it over to the new target CPU.
This allows to observe an eventually raised interrupt in the
transitional stage (old CPU, new vector) to be observed in the APIC
IRR and retriggered on the new target CPU and the new vector.The potential spurious interrupts caused by this are harmless and
can in the worst case expose a buggy driver (all handlers have to
be able to deal with spurious interrupts as they can and do happen
for various reasons).- Add the missing suspend/resume mechanism for the HYPERV hypercall
page which prevents resume hibernation on HYPERV guests. This
change got lost before the merge window.- Mask the IOAPIC before disabling the local APIC to prevent

This is a merge error on my part - the driver was merged into mainline
by commit c5951e7c8ee5 ("Merge tag 'mips_5.6' of git://../mips/linux")
over a week ago, but nobody apparently noticed that it didn't actually
build due to still having a reference to the devm_ioremap_nocache()
function, removed a few days earlier through commit 6a1000bd2703 ("Merge
tag 'ioremap-5.6' of git://../ioremap").Apparently this didn't get any build testing anywhere. Not perhaps all
that surprising: it's restricted to 64-bit MIPS only, and only with the
new SGI_MFD_IOC3 support enabled.I only noticed because the ioremap conflicts in the ARM SoC driver
update made me check there weren't any others hiding, and I found this
one.Signed-off-by: Linus Torvalds
