There are many isp driver in 4.4 kernel, let's add a dtsi
to help switch between them.

We now trap accesses to CNTVCT_EL0 when the counter is broken
enough to require the kernel to mediate the access. But it
turns out that some existing userspace (such as OpenMPI) do
probe for the counter frequency, leading to an UNDEF exception
as CNTVCT_EL0 and CNTFRQ_EL0 share the same control bit.
The fix is to handle the exception the same way we do for CNTVCT_EL0.
Fixes: a86bd139f2 ("arm64: arch_timer: Enable CNTVCT_EL0 trap if workaround is enabled")

Since people seem to make a point in breaking the userspace visible
counter, we have no choice but to trap the access. Add the required
handler.

In current code, the driver attributes of DWC2 controller is
created during driver initialization, if we get or set them
before finish probe device, the device's pointer in attribute
function will be NULL and this will crash the system. So this
patch make the function return directly if the pointer is NULL.
The attributes mention above:
/sys/bus/platform/drivers/usb20_otg/dwc_otg_conn_en
/sys/bus/platform/drivers/usb20_otg/force_usb_mode
/sys/bus/platform/drivers/usb20_otg/vbus_status

A lock-unlock is missing in ASHMEM_SET_SIZE ioctl which can result in a
race condition when mmap is called. After the !asma->file check, before
setting asma->size, asma->file can be set in mmap. That would result in
having different asma->size than the mapped memory size. Combined with
ASHMEM_UNPIN ioctl and shrinker invocation, this can result in memory
corruption.
