During CPU online/offline testing on a large system, one of the
processors got stuck after the message "bad: scheduling from the
idle thread!". The problem is that acpi_cpu_soft_notify() calls
acpi_bus_get_device() for all action types. CPU_STARTING and
CPU_DYING do not allow the notify handlers to sleep. However,
acpi_bus_get_device() can sleep in acpi_ut_acquire_mutex().
Change acpi_cpu_soft_notify() to return immediately for CPU_STARTING
and CPU_DYING as they have no action in this handler.

In acpi_processor_get_info(), ACPI processor info is initialized including
ID, namely CPU index. Currently, on a UP system running an SMP kerenl with
no LAPIC in the MADT, cpu0_initialized is checked to decide whether or not
the CPU has been initialized.
However, this check may not be sufficient for kdump kernels. Most of time
only 1 CPU is supported because of known problems in kdump kernels. So say
the multiple CPUs are present in the boot kernel and a crash happens on
one specific CPU, say CPU2. Then it jumps into the kdump kernel with
"nr_cpus=1" in the command line. In this situation, the kdump kernel
will reuse the ACPI resources from the crashed kernel directly. That
means all LAPIC instances are enabled in the MADT while only one CPU is
in use. In the kdump kernel, x86_cpu_to_apicid contains the correct APIC
ID and it's related to the CPU ID. If cpu0_initialized is checked only, 0
will be used as the CPU index instead of that APIC ID, which is not
correct.
In addition to checking cpu0_initialized, check acpi_lapic. If acpi_lapic
is 0, then no LAPIC is available from the MADT and the system should be
treated as a UP one without a LAPIC (that is, assign 0 to the CPU index).
Otherwise, use the original (valid) CPU index.

Setting the P state of the core to max at init time is a hold over
from early implementation of intel_pstate where intel_pstate disabled
cpufreq and loaded VERY early in the boot sequence. This was to
ensure that intel_pstate did not affect boot time. This in not needed
now that intel_pstate is a cpufreq driver.
Removing this covers the case where a CPU has gone through a manual
CPU offline/online cycle and the P state is set to MAX on init and the
CPU immediately goes idle. Due to HW coordination the P state request
on the idle CPU will drag all cores to MAX P state until the load is
reevaluated when to core goes non-idle.

Chromebooks (at least Acer C720 and Pixel) implement an ACPI object
for TPM, but don't implement the _DSM method to support PPI. As
a result, the TPM driver fails to load on those machines after
commit 1569a4c4ceba (ACPI / TPM: detect PPI features by checking
availability of _DSM functions) which causes them to fail to
resume from system suspend, becuase they require the TPM hardware
to be put into the right state during resume and the TPM driver
is necessary for that.
Fix the problem by making tpm_add_ppi() return 0 when tpm_ppi_handle
is still NULL after walking the ACPI namespace in search for the PPI
_DSM, which allows the TPM driver to load and operate the hardware
(during system resume in particular), but avoid creating the PPI
sysfs group in that case.
This change is based on a prototype patch from Jiang Liu.

Do not tell people in the Kconfig help when exactly we are going to
remove the deprecated ACPI interfaces in /proc, because, honestly,
we don't know. We will remove them when they are not used any more.
In particular, do not tell them that the interfaces will be removed
in a kernel release that already happened long ago.

Pull x86 fixes from Peter Anvin:
"A somewhat unpleasantly large collection of small fixes. The big ones
are the __visible tree sweep and a fix for 'earlyprintk=efi,keep'. It
was using __init functions with predictably suboptimal results.
Another key fix is a build fix which would produce output that simply
would not decompress correctly in some configuration, due to the
existing Makefiles picking up an unfortunate local label and mistaking
it for the global symbol _end.
Additional fixes include the handling of 64-bit numbers when setting
the vdso data page (a latent bug which became manifest when i386
started exporting a vdso with time functions), a fix to the new MSR
manipulation accessors which would cause features to not get properly

acpi_processor_add() assumes that present at boot CPUs
are always onlined, it is not so if a CPU failed to become
onlined. As result acpi_processor_add() will mark such CPU
device as onlined in sysfs and following attempts to
online/offline it using /sys/device/system/cpu/cpuX/online
attribute will fail.
Do not poke into device internals in acpi_processor_add()
and touch "struct device { .offline }" attribute, since
for CPUs onlined at boot it's set by:
topology_init() -> arch_register_cpu() -> register_cpu()
before ACPI device tree is parsed, and for hotplugged
CPUs it's set when userspace onlines CPU via sysfs.

commit <mmc: rtsx: add support for pre_req and post_req> did use
mutex_unlock() in tasklet, but mutex_unlock() can't be used in
tasklet(atomic context). The driver needs to use mutex to avoid
concurrency, so we can't use tasklet here, the patch need to be
removed.
The spinlock host->lock and pcr->lock may deadlock, one way to solve
the deadlock is remove host->lock in sd_isr_done_transfer(), but if
using workqueue the we can avoid using the spinlock and also avoid
the problem.
