#     
#     Merge yet more updates from Andrew Morton:
#      "A few final bits:
#     
#        - large changes to vmalloc, yielding large performance benefits
#     
#        - tweak the console-flush-on-panic code
#     
#        - a few fixes"
#     
#     * emailed patches from Andrew Morton <akpm@linux-foundation.org>:
#       panic: add an option to replay all the printk message in buffer
#       initramfs: don't free a non-existent initrd
#       fs/writeback.c: use rcu_barrier() to wait for inflight wb switches going into workqueue when umount
#       mm/compaction.c: correct zone boundary handling when isolating pages from a pageblock
#       mm/vmap: add DEBUG_AUGMENT_LOWEST_MATCH_CHECK macro
#       mm/vmap: add DEBUG_AUGMENT_PROPAGATE_CHECK macro
#       mm/vmalloc.c: keep track of free blocks for vmap allocation
