Commit 2760878662 ("clk: Bail out when calculating phase fails during
clk registration") introduced a check on error values at the time the
clock is registered to bail out when such an error occurs. However, it
doesn't check whether the returned value is positive which will happen
if the driver returns a non-zero phase. Since a phase is usually a
non-zero positive number this ends up returning something that isn't 0
to the caller of __clk_core_init(), making most clks fail to register
if they implement a phase clk op and return anything besides 0 for the
phase.
Fix this by returning the error if phase is less than zero or just
return zero if the phase is a positive number.

There's some confusion about when recalc is done for the rate and
accuracy clk consumer APIs in relation to the prepare lock being taken.
Oddly enough, we take the lock again in debugfs APIs so that we can call
the internal "clk_core" APIs to get these fields with any necessary
recalculations. Instead of having this confusion, let's introduce a
recalc variant of these two consumer APIs as internal helpers and call
them from the consumer APIs and the debugfs code so that we don't take
the lock more than once.

We don't check for errors from clk_ops::get_phase() before storing away
the result into the clk_core::phase member. This can lead to some fairly
confusing debugfs information if these ops do return an error. Let's
skip the store when this op fails to fix this. While we're here, move
the locking outside of clk_core_get_phase() to simplify callers from
the debugfs side.

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.

Pull vboxfs from Al Viro:
"This is the VirtualBox guest shared folder support by Hans de Goede,
with fixups for fs_parse folded in to avoid bisection hazards from
those API changes..."

fs: Add VirtualBox guest shared folder (vboxsf) support
- 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 potentially
stale IOAPIC remote IRR bits which cause stale interrupt lines after
resume.
