Samuel Zhang 2640e81947 PM: hibernate: shrink shmem pages after dev_pm_ops.prepare() ... When hibernate with data center dGPUs, huge number of VRAM data will be moved to shmem during dev_pm_ops.prepare(). These shmem pages take a lot of system memory so that there's no enough free memory for creating the hibernation image. This will cause hibernation fail and abort. After dev_pm_ops.prepare(), call shrink_all_memory() to force move shmem pages to swap disk and reclaim the pages, so that there's enough system memory for hibernation image and less pages needed to copy to the image. This patch can only flush and free about half shmem pages. It will be better to flush and free more pages, even all of shmem pages, so that there're less pages to be copied to the hibernation image and the overall hibernation time can be reduced.
