      IB/mlx5: Fix RC transport send queue overhead computation · 75c1657e
      Leon Romanovsky authored
      Fix the RC QPs send queue overhead computation to take into account
      two additional segments in the WQE which are needed for registration
      operations.
      
      The ATOMIC and UMR segments can't coexist together, so chose maximum out
      of them.
      
      The commit 9e65dc37 ("IB/mlx5: Fix RC transport send queue overhead
      computation") was intended to update RC transport as commit messages
      states, but added the code to UC transport.

      Changes from v4:
      - as suggested by Doug Ledford, optimized spinlock usage,
      i.e. ipoib_mcast_join() is called with lock held.
      Changes from v3:
      - sync with priv->lock before flag check.
      Chages from v2:
      - Move check for OPER_UP flag state to mcast_join() to
      ensure no event worker is in progress.
      - minor style fixes.
      Changes from v1:
      - No need to lock again if error detected.

      EVM: Use crypto_memneq() for digest comparisons · 613317bd
      Ryan Ware authored
      This patch fixes vulnerability CVE-2016-2085.  The problem exists
      because the vm_verify_hmac() function includes a use of memcmp().
      Unfortunately, this allows timing side channel attacks; specifically
      a MAC forgery complexity drop from 2^128 to 2^12.  This patch changes
      the memcmp() to the cryptographically safe crypto_memneq().

      ARC: mm: Introduce explicit super page size support · 37eda9df
      Vineet Gupta authored
      MMUv4 supports 2 concurrent page sizes: Normal and Super [4K to 16M]
      
      So far Linux supported a single super page size for a given Normal page,
      depending on the software page walking address split.
      e.g. we had 11:8:13 address split for 8K page, which meant super page
      was 2 ^(8+13) = 2M (given that THP size has to be PMD_SHIFT)
      
      Now we turn this around, by allowing multiple Super Pages in Kconfig
      (currently 2M and 16M only) and forcing page walker address split to
      PGDIR_SHIFT and PAGE_SHIFT
      
      For configs without Super page, things are same as before and
      PGDIR_SHIFT can be hacked to get non default address split
      
      The motivation for this change is a customer who needs 16M super page
      and a 8K Normal page combo.

      If a /d/binder/proc/[pid] entry is kept open after linux has

      an invalid binder_proc that has been stashed in the debugfs

      has not been freed by looking for it within the global process list
      whilst the global lock is held. If the ptr is not valid, print nothing.
