irqchip: gicv3: Add GICv3 access control Kconfig option
Some SOCs(System-on-chip) S/W configurations restricts the access
to particular set of the GIC registers to prevent invalid
accesses for the security reasons. Provide a configuration
option for the GICv3 driver and also restrict the access
of the GICR_WAKER registers from the non-secure world.
If this Kconfig option is not selected then it means that
access control configuration is enabled from the secure world.

arm: traps: emulate a MRCC instruction reading CNTPCT register
A user space application is planned to support feature for
synchronized timestamp among debug packets across peripherals.
As part of the feature, it is responsible for providing physical
timer count value to user space. If memory mapped timer is used
in ARM arch, Usersapce can't read the physical timer count directly
with a MRCC ASM instruction. So Kernel traps the instruction and
returns the physical timer count.

memshare: Release the memory only if no allocation is done
Currently, memshare relies on the system monitor only for
releasing memory for the allocated clients. It may happen that
XPU is still intact on the modem side while driver tries to
release the memory. This patch ensures that memory release only
happens if XPU is released.

soc: qcom: Use arch_counter_get_cntvct instead of arch_counter_get_cntpct
Kernel version 4.4 has deprecated the use of *pct versions for 64 bit
targets. Hence moving to vct as recommended.

arm64: psci: Support for OS initiated scheme
Existing PSCI implementation supports platform coordinated means of low
power modes where cluster low power modes are aggregated at the platform
level. Adding support for OS initiated scheme, where is OS is responsible
for selecting cluster low power modes based on last man determination. With
OS initiated scheme, the OS can make better cluster decisions based on
wakeup times of CPUs within a cluster.
To this effect, in OS initiated schemes, the composite state ID is computed
by the idle driver before calling into the cpu_suspend API. The PSCI driver
is modified to use the composite ID to distinguish between retention and
non-retention states.

ARM64: smp: Prevent cluster LPM modes when pending IPIs on cluster CPUs
LPM modes can fail if there is a pending IPI interrupt at GIC CPU
interface. On some usecases frequent failure of LPM modes can
cause power and performance degradation. Hence, prevent cluster
low power modes when there is a pending IPI on cluster CPUs.
