The patch numbering is in continuation of Khuong's patches recently sent.

This is a roll-up of the following upstream patches needed to support
ARM64 ACPI LPI:
b6ec26f ACPI / processor_idle: replace PREFIX with pr_fmt
db62fda ACPI / processor : add support for ACPI0010 processor container
504997c ACPI / sleep: move acpi_processor_sleep to sleep.c states
c3fbbf9 ARM: 8586/1: cpuidle: make arm_cpuidle_suspend() a bit more
625fe4f ARM: cpuidle: Pass on arm_cpuidle_suspend()'s return value
35ae713 ACPI / processor_idle: introduce ACPI_PROCESSOR_CSTATE
a36a7fe ACPI / processor_idle: Add support for Low Power Idle(LPI)
ce3ad71 arm64: cpuidle: drop __init section marker to arm_cpuidle_init
220276e cpuidle: introduce CPU_PM_CPU_IDLE_ENTER macro for ARM{32, 64}
5a611ed arm64: add support for ACPI Low Power Idle(LPI)
8fc85c6 ACPI: enable ACPI_PROCESSOR_IDLE on ARM64
ccd9432 irqchip/gicv3: Remove disabling redistributor and group1
non-secure
8b6f249 ARM: 8511/1: ARM64: kernel: PSCI: move PSCI idle management code
to
1d2d8de drivers: firmware: psci: drop duplicate const from psci_of_match
21e8868 drivers: firmware: psci: make two helper functions static
2b9cf18 drivers: firmware: psci: make two helper functions inline
978fa43 drivers: firmware: psci: unify enable-method binding on ARM
{64,32}-bit
5e7c17d drivers: firmware: psci: use const and __initconst for
psci_cpuidle_ops
c2a25c1 drivers: firmware: psci: initialise idle states using ACPI LPI

Thanks,
