This series, which depends on the previous two, introduces static_call().
static_call(), is the idea of static_branch() applied to indirect function
calls. Remove a data load (indirection) by modifying the text.
These patches are still based on the work Josh did earlier, but incorporated
feedback
Future patches will need to poke a RET instruction, provide the
infrastructure required for this.

Currently compound controls do not have a simple way of initializing its
values. This results in ofuscated code with type_ops init.
This patch introduces a new field on the control with the default value
for the compound control that can be set with the brand new
v4
This helper function simplifies the code by not needing a union
v4l2_ctrl_ptr and an assignment every time we need to use

This patch restores the correct DMA mask after switching back to device
mode.
The issue occurred because Device part of controller use 32 bits DMA and
Host side use 64 bits DMA. During loading XHCI driver the DMA mask
used by driver is overwritten by XHCI driver so it must be restored
to 32 bits.
Minor white space fix.

Hi,
Here are 2 fixes we found while testing the cdns3 driver
on our platform.
The first one fixes a corner case where super-speed in host mode
doesn't work if device was plugged before the cdns3 driver probes.
The second one fixes the case when gadget driver is
limited to full-speed.
cheers,

At startup we should trigger the HW state machine
only if it is OTG mode. Otherwise we should just
start the respective role.
Initialize idle role by default. If we don't do this then
cdns3_idle_role_stop() is not called when switching to
host/device role and so lane switch mechanism
doesn't work.
We need to disable USB3 PHY for full-speed mode else
gadget mode is broken.

Add it to a new mmap.c object, that will carry all the mmap related
functions.

Move perf_mmap__unmap() from tools/perf to libperf, to internal header
internal/mmap.h. It will be used in the following patches. And rename
the existing perf's function to mmap__munmap().
