Pull regmap fixes from Mark Brown:
"The cleanups for the way we handle type information introduced during
the merge window revealed that we'd been abusing the irq APIs for a

that'd be a bit much to do as a bug fix"

Pull powerpc fixes from Michael Ellerman:
"A couple of weeks of fixes.
There's one fix for an oops on Power9 machines with Open CAPI
adapters.
And a fix for probable memory corruption in some of the new NPU code,
caught by smatch though and not seen in the wild.
Plus a few other minor fixes.
There's one non-fix which is the perf_regs change. That was sent
during the merge window but I accidentally only merged the first of
two patches in the series. It's been in linux-next so hopefully
doesn't conflict with anything in acme's tree.

Pull ACPI fixes from Rafael Wysocki:
"These fix an ACPI initialization ordering issue introduced in the 4.17
time frame and causing functional problems to appear on multiple
systems and fix some fallout of the recent change to enable building
kernels with ACPI support and without PCI.
Specifics:
- Restore the ACPI initialization ordering changed implicitly by the
module-level AML handling rework during the 4.17 development cycle
that caused the EC address space handler based on information from
ECDT to be set up before loading AML definition blocks, making it
effectively not accessible by AML on some systems that don't work
as expected any more (Rafael Wysocki).
- Add direct dependencies on PCI to Kconfig in multiple places for
code that depends on both ACPI and PCI, but the PCI dependency was
implicitly satisfied by the ACPI dependency before, to prevent
invalid configurations from being created, for example by
randconfig (Sinan Kaya)"

The function jz_nand_ioremap_resource() needs a pointer to an __iomem

When lp55xx_read() fails, "status" is an uninitialized variable and thus
may contain random value; using it leads to undefined behaviors.

There's a race between afs_make_call() and afs_wake_up_async_call() in the
case that an error is returned from rxrpc_kernel_send_data() after it has
queued the final packet.
afs_make_call() will try and clean up the mess, but the call state may have
been moved on thereby causing afs_process_async_call() to also try and to
delete the call.
Fix this by:
(1) Getting an extra ref for an asynchronous call for the call itself to
hold. This makes sure the call doesn't evaporate on us accidentally
and will allow the call to be retained by the caller in a future
patch. The ref is released on leaving afs_make_call() or
afs_wait_for_call_to_complete().
(2) In the event of an error from rxrpc_kernel_send_data():
(a) Don't set the call state to AFS_CALL_COMPLETE until *after* the
call has been aborted and ended. This prevents
afs_deliver_to_call() from doing anything with any notifications
it gets.
(b) Explicitly end the call immediately to prevent further callbacks.
(c) Cancel any queued async_work and wait for the work if it's
executing. This allows us to be sure the race won't recur when we
change the state. We put the work queue's ref on the call if we
managed to cancel it.
(d) Put the call's ref that we got in (1). This belongs to us as long
as the call is in state AFS_CALL_CL_REQUESTING.

A cb_interest record is not necessarily attached to the vnode on entry to
afs_validate(), which can cause an oops when we try to bring the vnode's
cb_s_break up to date in the default case (ie. no current callback promise
and the vnode has not been deleted).
Fix this by simply removing the line, as vnode->cb_s_break will be set when
needed by afs_register_server_cb_interest() when we next get a callback
promise from RPC call.
The oops looks something like:

The disable_acs_redir parameter stores a pointer to the string passed to
pci_setup(). However, the string passed to PCI setup is actually a
temporary copy allocated in static __initdata memory. After init, once the
memory is freed, it is no longer valid to reference this pointer.
This bug was noticed in v5.0-rc1 after a change in commit c5eb1190074c
("PCI / PM: Allow runtime PM without callback functions") caused
pci_disable_acs_redir() to be called during shutdown which manifested
as an unable to handle kernel paging request at:
RIP: 0010:pci_enable_acs+0x3f/0x1e0

It was also likely possible to trigger this bug when hotplugging PCI
devices.
To fix this, instead of storing a pointer, we use kstrdup() to copy the
disable_acs_redir_param to its own buffer which will never be freed.

Commit c3ff2a5193fa ("powerpc/32: add stack protector support")
caused kernel panic on PowerPC when an external module is used with
CONFIG_STACKPROTECTOR because the 'prepare' target was not executed
for the external module build.
Commit e07db28eea38 ("kbuild: fix single target build for external
module") turned it into a build error because the 'prepare' target is
now executed but the 'prepare0' target is missing for the external
module build.
External module on arm/arm64 with CONFIG_STACKPROTECTOR_PER_TASK is
also broken in the same way.
Move 'PHONY += prepare0' to the common place. GNU Make is fine with
missing rule for phony targets. I also removed the comment which is
wrong irrespective of this commit.
I minimize the change so it can be easily backported to 4.20.x
To fix v4.20, please backport e07db28eea38 ("kbuild: fix single target
build for external module"), and then this commit.

[Why]
Backlight is conceptually a property of links, not streams.
All backlight programming is done on links, but there is a
stream property bl_pwm_level that is used to restore backlight
on dpms on and s3 resume. This is unnecessary, as backlight
is already restored by hardware with no driver intervention.
[How]
Remove bl_pwm_level, and the stream argument to set_backlight

It's possible that a pid has died before we take the rcu lock, in which
case we can't walk the ancestry list as it may be detached. Instead, check
for death first before doing the walk.

Commit f94c8d11699759 ("sched/clock, x86/tsc: Rework the x86 'unstable'

[ 187.251137] OOM killer disabled.

Fix that by setting xen_sched_clock_offset at resume time to ensure a
monotonic clock value.
[boris: replaced pr_info() with pr_info_once() in xen_callback_vector()
to avoid printing with incorrect timestamp during resume (as we
haven't re-adjusted the clock yet)]

cancel_delayed_work_sync() was called for any queue, but it should only
be called for the queue that is associated with the currently running job.
Otherwise, if two filehandles are streaming at the same time, then closing the
first will cancel the work which might still be running for a job from the
second filehandle. As a result the second filehandle will never be able to
finish the job and an attempt to stop streaming on that second filehandle will
stall.
