kernel.git/arch/arm/kernel/psci.c, branch linux-3.11.yHosts the 0x221E linux distro kernel.
https://git.0xinfinity.dev/distro/kernel.git/atom?h=linux-3.11.y2013-05-21T14:24:11Zarm: introduce psci_smp_ops2013-05-21T14:24:11ZStefano Stabellini2013-05-21T14:24:11Zurn:sha1:05774088391c7430f6a4c1d5d18196ef17bb3ba9
Rename virt_smp_ops to psci_smp_ops and move them to arch/arm/kernel/psci_smp.c.
Remove mach-virt/platsmp.c, now unused.
Compile psci_smp if CONFIG_ARM_PSCI and CONFIG_SMP.
Add a cpu_die smp_op based on psci_ops.cpu_off.
Initialize PSCI before setting smp_ops in setup_arch.
If PSCI is available on the platform, prefer psci_smp_ops over the
platform smp_ops.

ARM: psci: add support for PSCI invocations from the kernel2013-01-10T21:10:20ZWill Deacon2012-12-12T19:20:52Zurn:sha1:2bdd424f26be1c98b6e3d9acfffb5559c131c888
This patch adds support for the Power State Coordination Interface
defined by ARM, allowing Linux to request CPU-centric power-management
operations from firmware implementing the PSCI protocol.
