bounces through the host system before being injected into the VM.

This interrupt controller is the new root interrupt controller with
the timer, PMU events, and IPIs, and the bcm2835's interrupt
controller is chained off of it to handle the peripherals.
SMP IPI support was mostly written by Andrea Merello, while I wrote
most of the rest of the IRQ handling.
This is a new per-cpu root interrupt controller on the Raspberry Pi 2,
which will chain to the bcm2835 interrupt controller for peripheral

For BCM2836, we want to chain into this IRQ chip from the root
controller, and for chaining we need to do something else instead of
handle_IRQ() once we have decoded the IRQ.
Note that this changes the behavior a little bit: Previously for a
non-shortcut IRQ, we'd loop reading and handling the

This is a little over half of the diff for the Raspberry Pi 2
platform. A full series you can build and test can be found at:

The subject has a typo "kasl" should be "kaslr".

Other than that, yeah, there's no good reason to pass that around.

It would be nice to have a more verbose changelog here -- i.e. why we want
to do such change and what could go wrong if IRQ is
The IRQCHIP_DECLARE macro migrated to 'include/linux/irqchip.h'. See commit

I'm not an 80 column zealot.
This is for staging isn't it?
Code churn there is expected and somewhat desired.
A lot

Kaslr extended kernel text mapping region size from 512M to 1G,
namely CONFIG_RANDOMIZE_BASE_MAX_OFFSET. This means kernel text
can be mapped to below region:
[__START_KERNEL_map + LOAD_PHYSICAL_ADDR, __START_KERNEL_map + 1G]
Introduce a function find_random_virt_offset() to
parse_elf is using local memcpy to move section to running position.
That memcpy actually only support no overlapping or dest < src.
Add checking in memcpy to find out wrong with future use, at that time
we will need to have backward memcpy for it.
Also put comments in parse_elf about the fact.

When process 32 bit relocation tables a local variable extended is

Several auxiliary functions and slots[] are not needed any more since
struct slot_area is used to store the slot info of kaslr now. Hence
remove them in this patch.
