media: uvcvideo: set system status to performance when stream on
...
For rockchip platforms, set performance frequency for the
memory controller when uvc stream on, and clear it after
uvc stream off. It can improve uvc streaming stability.

BACKPORT: firmware_loader: Abort all upcoming firmware load request once reboot triggered
...
There could be following scenario where there is a ongoing reboot
is going from processA which tries to call all the reboot notifier
callback and one of them is firmware reboot call which tries to
abort all the ongoing firmware userspace request under fw_lock but
there could be another processB which tries to do request firmware,
which came just after abort done from ProcessA and ask for userspace
to load the firmware and this can stop the ongoing reboot ProcessA
to stall for next 60s(default timeout) which may not be expected
behaviour everyone like to see, instead we should abort any firmware
load request which came once firmware knows about the reboot through
notification.

ANDROID: Add Interrupt Hook for madvise Compression
...
We introduce an interrupt hook in Android to manage memory compression
using madvise, improving user experience.
Currently, when a user returns to the home screen, memory compression is
triggered using madvise. The vma and PAGEOUT flag are sent to
process_madvise, initiating page reclaim.
However, if an app is re-opened soon after starting compression, the
reclaim process can cause read delays, leading to potential lag.
To resolve this, we propose to skip pte range traversal. By comparing
the vma's task uid with the current app's uid, we can identify and
interrupt the madvise operation for that vma.
Implementing this requires a vendor hook for should_end_madvise. This
allows us to skip traversal, enhancing user experience.
