      context_tracking: Restore previous state in schedule_user · 7cc78f8f
      由 Andy Lutomirski 提交于 
      It appears that some SCHEDULE_USER (asm for schedule_user) callers
in arch/x86/kernel/entry_64.S are called from RCU kernel context,
and schedule_user will return in RCU user context.  This causes RCU
warnings and possible failures.

This is intended to be a minimal fix suitable for 3.18.

      Pull devicetree bugfix from Grant Likely:
 "One more bug fix for v3.18.  I debated whether or not to send you this
  merge request because we're at such a late rc.  The bug isn't critical
  in that there is only one system known to be affected and the patch is
  easy to backport.  The codepath is used by pretty much every DT based
  system, so there is risk a of regression (it /should/ be safe, but
  I've been bitten by stuff that should be safe before).  I've had it in
  linux-next for a week and haven't received any complaints.

  I think it probably should just be merged right away rather than
  waiting for the merge window and backporting.  It does fix a real bug
  and the code is theoretically safer after the change.  I can't think
  of any situation where it would be dangerous to reserve the DT memory
  an extra time.

  Summary from tag:

    Single bugfix for boot failure seen in the wild.  The memory reserve
    code tries to be clever about reserving the FDT, but it should just
    go ahead and reserve it unconditionally to avoid the problem of
    partial overlap described in the patch"

      slab: fix nodeid bounds check for non-contiguous node IDs · 7c3fbbdd
      由 Paul Mackerras 提交于 
      The bounds check for nodeid in ____cache_alloc_node gives false
positives on machines where the node IDs are not contiguous, leading to
a panic at boot time.  For example, on a POWER8 machine the node IDs are
typically 0, 1, 16 and 17.  This means that num_online_nodes() returns
4, so when ____cache_alloc_node is called with nodeid = 16 the VM_BUG_ON
triggers, like this:

  kernel BUG at /home/paulus/kernel/kvm/mm/slab.c:3079!
  Call Trace:
    .____cache_alloc_node+0x5c/0x270 (unreliable)
    .kmem_cache_alloc_node_trace+0xdc/0x360
    .init_list+0x3c/0x128
    .kmem_cache_init+0x1dc/0x258
    .start_kernel+0x2a0/0x568
    start_here_common+0x20/0xa8

To fix this, we instead compare the nodeid with MAX_NUMNODES, and
additionally make sure it isn't negative (since nodeid is an int).  The
check is there mainly to protect the array dereference in the get_node()
call in the next line, and the array being dereferenced is of size
MAX_NUMNODES.  If the nodeid is in range but invalid (for example if the
node is off-line), the BUG_ON in the next line will catch that.

Fixes: 14e50c6a ("mm: slab: Verify the nodeid passed to ____cache_alloc_node")
