[PATCH v2] mm, kasan: switch SLUB to stackdepot, enable memory quarantine for SLUB

For KASAN builds: - switch SLUB allocator to using stackdepot instead of storing the allocation/deallocation stacks in the objects; - define SLAB_RED_ZONE, SLAB_POISON, SLAB_STORE_USER to zero, effectively disabling these debug features, as they're redundant in the presence of KASAN; -

[PATCH 1/3] dma-buf/sync_file: only enable fence signalling during wait

From: Gustavo Padovan Signalling doesn't need to be enabled at sync_file creation, it is only required if userspace waiting the fence to signal through poll(). Thus we delay fence_add_callback() until poll is called. It only adds the callback the first time

[PATCH 5/8] tty: serial: fsl-lpuart: Use cyclic DMA for Rx

The initial approach of DMA implementatin for RX is inefficient due to switching from PIO to DMA, this leads to overruns especially on instances with the smaller FIFO. To address these issues this patch uses a cyclic DMA for receiver path. Some part of the code is borrowed from atmel serial
