Powerpc currently resets a CPU's idle task preempt_count to 0 before
said task starts executing the secondary startup routine (and becomes an
idle task proper).
This conflicts with commit f1a0a376ca ("sched/core: Initialize the
idle task with preemption disabled").
which initializes all of the idle tasks' preempt_count to
PREEMPT_DISABLED during smp_init(). Note that this was superfluous
before said commit, as back then the hotplug machinery would invoke
init_idle() via idle_thread_get(), which would have already reset the
CPU's idle task's preempt_count to PREEMPT_ENABLED.
Get rid of this preempt_count write.

Using register asm statements has been proven to be very error prone,
especially when using code instrumentation where gcc may add function
calls, which clobbers register contents in an unexpected way.
Therefore get rid of register asm statements in ap code. There are also
potential bugs, depending on inline decisions of the compiler.
E.g. for:
static inline struct ap_queue_status ap_tapq(ap_qid_t qid, unsigned long *info)
{
register unsigned long reg0 asm ("0") = qid;
register struct ap_queue_status reg1 asm ("1");
register unsigned long reg2 asm ("2");
asm volatile(".long 0xb2af0000" /* PQAP(TAPQ) */
: "=d" (reg1), "=d" (reg2)
: "d" (reg0)
: "cc");
if (info)
*info = reg2;
return reg1;
}
In case of KCOV the "if (info)" line could cause a generated function
call, which could clobber the contents of both reg2, and reg1.
Similar can happen in case of KASAN for the "*info = reg2" line.
Even though compilers will likely inline the function and optimize
things away, this is not guaranteed.
To get rid of this bug class, simply get rid of register asm constructs.
Note: The inline function ap_dqap() will be handled in a
separate patch because this one requires an addressing of the
odd register of a register pair (which is done with %N[xxx] in
the assembler code) and that's currently not supported by clang.

Rework of the ap_dqap() inline function with the dqap inline assembler
invocation and the caller code in ap_queue.c to be able to handle
replies which exceed the receive buffer size.
ap_dqap() now provides two additional parameters to handle together
with the caller the case where a reply in the firmware queue entry
exceeds the given message buffer size. It depends on the caller how to
exactly handle this. The behavior implemented now by ap_sm_recv() in
ap_queue.c is to simple purge this entry from the firmware queue and
let the caller 'receive' a -EMSGSIZE for the request without
delivering any reply data - not even a truncated reply message.
However, the reworked ap_dqap() could now get invoked in a way that
the message is received in multiple parts and the caller assembles the

Fix this by removing jbd2_journal_[un]register_shrinker() functions,

Until now, memory provided by a single virtio-mem device was usually
either onlined completely to ZONE_MOVABLE (online_movable) or to
ZONE_NORMAL (online_kernel); however, that will change in the future.
There are two reasons why we want to track to which zone a memory blocks
belongs to and prioritize ZONE_MOVABLE blocks:
1) Memory managed by ZONE_MOVABLE can more likely get unplugged, therefore,
resulting in a faster memory hotunplug process. Further, we can more
reliably unplug and remove complete memory blocks, removing metadata
allocated for the whole memory block.
2) We want to avoid corner cases where unplugging with the current scheme
(highest to lowest address) could result in accidential zone imbalances,
whereby we remove too much ZONE_NORMAL memory for ZONE_MOVABLE memory
of the same device.
Let's track the zone via memory block states and try unplug from
ZONE_MOVABLE first. Rename VIRTIO_MEM_SBM_MB_ONLINE* to
VIRTIO_MEM_SBM_MB_KERNEL* to avoid even longer state names.
In commit 27f852795a ("virtio-mem: don't special-case ZONE_MOVABLE"),
we removed slightly similar tracking for fully plugged memory blocks to
support unplugging from ZONE_MOVABLE at all -- as we didn't allow partially
plugged memory blocks in ZONE_MOVABLE before that. That commit already
mentioned "In the future, we might want to remember the zone again and use
the information when (un)plugging memory."

For split virtqueue, we used to depend on the address, length and

for the case since the device can manipulate the behavior of virtio
driver, IOMMU drivers and swiotlb.
For safety, maintain the DMA address, DMA length, descriptor flags and
next filed of the non indirect descriptors in vring_desc_state_extra
when DMA API is used for virtio as we did for packed virtqueue and use
those metadata for performing DMA operations. Indirect descriptors
should be safe since they are using streaming mappings.
With this the descriptor ring is write only form the view of the
driver.

Pull more ACPI updates from Rafael Wysocki:
"These include fixes of the recently introduced support for the
Platform Runtime Mechanism (PRM) feature, a new backlight quirk, a
suspend-to-idle wakeup fix for non-Intel platforms and a fix for the
AMBA bus resource list in /proc/iomem.
Specifics:
- Fix up the recently added Platform Runtime Mechanism (PRM) support
by correnting a couple of implementation mistakes in it and adding
a Kconfig help text to describe it (Aubrey Li, Rafael Wysocki).
- Add backlight quirk for Dell Vostro 3350 (Hans de Goede).
- Avoid spurious wakeups from suspend-to-idle on non-Intel platforms
by restricting special EC GPE handling to the Intel ones (Mario
Limonciello).
- Modify the AMBA bus support in ACPI to avoid adding using resource
names in /proc/iomem (Liguang Zhang)"
* tag 'acpi-5.14-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
ACPI: Do not singal PRM support if not enabled
ACPI: Correct \_SB._OSC bit definition for PRM
ACPI: Kconfig: Provide help text for the ACPI_PRMT option
ACPI: PM: Only mark EC GPE for wakeup on Intel systems
ACPI: video: Add quirk for the Dell Vostro 3350
ACPI: AMBA: Fix resource name in /proc/iomem
- Drop the ->stop_cpu() (not really useful) and ->resolve_freq()
(unused) cpufreq driver callbacks and modify the users of the
former accordingly (Viresh Kumar, Rafael Wysocki).
- Add frequency invariance support to the ACPI CPPC cpufreq driver
again along with the related fixes and cleanups (Viresh Kumar).
- Update the Meditak, qcom and SCMI ARM cpufreq drivers (Fabien
Parent, Seiya Wang, Sibi Sankar, Christophe JAILLET).
- Rename black/white-lists in the DT cpufreq driver (Viresh Kumar).
- Add generic performance domains support to the dvfs DT bindings
(Sudeep Holla).
- Refine locking in the generic power domains (genpd) support code
to avoid lock dependency issues (Stephen Boyd).
- Update the MSM and qcom ARM cpuidle drivers (Bartosz Dudziak).
- Simplify the PM core debug code by using ktime_us_delta() to
compute time interval lengths (Mark-PK Tsai).
