Add notifiers for hotplug and power collapse in perf events.
Preserve counters and user enables across these events.
Disable and enable interrupts across events.
This allows perf-events to be used in an environment where
cores are power collapsing and being hotplugged.

Modify the firmware upgrade procedure based on the following requirements:
If config id of the firmware file is greater than the config id in the
device and if packrat id of the firmware img file is greater than the
firmware build id in the device, then during the firmware upgrade
procedure, both firmware and config areas are upgraded. Otherwise,
if the packrat id of the firmware img file is equal to the firmware
build id in the device, then only the config area is upgraded. However,
if the packrat id of the firmware img file is lesser than the firmware
build id in the device, then it is considered as an error.
Similarly, if config id of the firmware file is equal to the config id
in the device and if packrat id of the firmware img file is greater than
the firmware build id in the device, then during the firmware upgrade
procedure, both firmware and config areas are upgraded. Otherwise, if
the packrat id of the firmware img file is equal to the firmware build
id in the device, then no upgrade is needed. However, if the packrat id
of the firmware img file is lesser than the firmware build id in the
device, then it is considered as an error.

It's good security practice to make your executable code read-only. On
hypervisor-enabled targets, this can be trivially accomplished by
removing the writable attribute from all stage-2 mappings of the kernel
text. Add a small library and initcall to do this.
Due to constraints on the hypervisor, this needs to happen before all of
the cores are brought out of reset, so make it an early_initcall.
