Since vendors might depend on them for their system heap
implementations, make the page-pool/deferred-free libraries built-in to
freeze their KMI.

In order to detect whether a GICv3 CPU interface is MMIO capable,
we switch ICC_SRE_EL1.SRE to 0 and check whether it sticks.
However, this is only possible if *ALL* of the HCR_EL2 interrupt
overrides are set, and the CPU is perfectly allowed to ignore
the write to ICC_SRE_EL1 otherwise. This leads KVM to pretend
that a whole bunch of ARMv8.0 CPUs aren't MMIO-capable, and
breaks VMs that should work correctly otherwise.
Fix this by setting IMO/FMO/IMO before touching ICC_SRE_EL1,
and clear them afterwards. This allows us to reliably detect
the CPU interface capabilities.

This patch creates a config that can be used to disable the automount of
tracefs in the debugfs filesystem. Since the automount happens everytime
the path /sys/kernel/debug/tracing is accessed, unmounting from
userspace is ineffective against it.
The config is intended to prevent new tracefs clients from depending on
the automounted tracefs instance mounted at /sys/kernel/debug/tracing
instead of the one at /sys/kernel/tracing. Since Android R launching
devices and newer cannot mount debugfs in production builds, the
config is intended to minimize the difference between user and
userdebug builds w.r.t to tracefs and prevent regresssions.

Before reboot if the DCDC is disabled,
the DCDC is still disabled after restart.
We have an method to workaround:
Use vsel pin to switch the voltage between value in FAN53555_VSEL0
and FAN53555_VSEL1. If VSEL pin is inactive, the voltage of DCDC
are controlled by FAN53555_VSEL0, when we pull vsel pin to active,
they would be controlled by FAN53555_VSEL1.
In this case, we can set FAN53555_VSEL1 to disable dcdc,
So we can make vsel pin to active to disable dcdc,
VSEL pin is inactive to enable DCDC.

Deferred probe usually runs only on pinned kworkers, which might take
longer time if a device contains multiple sub-devices. One such case
is of sound card on mobile devices, where we have good number of
mixers and controls per mixer.
We observed boot up improvement - deferred probes take ~600ms when bound
to little core kworker and ~200ms when deferred probe is queued on
unbound wq. This is due to scheduler moving the worker running deferred
probe work to big CPUs. Without this change, we see the worker is running
on LITTLE CPU due to affinity.
Since kworker runs deferred probe of several devices, the locality may
not be important. Also, init thread executing driver initcalls, can
potentially migrate as it has cpu affinity set to all cpus.In addition
to this, async probes use unbounded workqueue. So, using unbounded wq for
deferred probes looks to be similar to these w.r.t. scheduling behavior.

In commit 731d2da95e ("ANDROID: usb: host: export xhci symbols for

function prototype in xhci.h so that it can actually be called properly.
To resolve this, add the correct function prototype.
Based on a larger patch from Daehwan Jung, but split out into an

There could be a scenario where we define some region
in normal memory and use them store to logs which is later
retrieved by bootloader during warm reset.
In this scenario, we wanted to treat this memory as normal
cacheable memory instead of default behaviour which
is an overhead. Making it cacheable could improve
performance.
This commit gives control to change mem_type from Device
tree, and also documents the value for normal memory.

There are writable 32 bits for PMU_GPIO0's iomux, so add the
IOMUX_WRITABLE_32BIT to read iomux register at first, it would
not change others' bits.

The origin commit is 'pinctrl: rockchip: Add slew rate support for
px30', this commit only pick the support codes without px30, that will
be supported in another path.
The usage of slew rate is needed to config it at DTS,
such as:
fast speed: slew-rate = <1>;
slew speed: slew-rate = <0>;
