      arm64: update 32-bit kuser helpers to ARMv8 · d0f38f91
      Robin Murphy 提交于
      This patch updates the barrier semantics in the kuser helper functions
      to take advantage of the ARMv8 additions to AArch32, which are
      guaranteed to be available in situations where these functions will be
      called.
      
      Note that this slightly changes the cmpxchg functions in that they are
      no longer necessarily full barriers if they return 1. However, the
      documentation only states they include their own barriers "as needed",
      not that they are obligated to act as a full barrier for the caller.

      Linus Torvalds 提交于
      Pull SCSI target fixes from Nicholas Bellinger:
       "Here are the outstanding target fixes queued up for v3.12-rc4 code.
      
        The highlights include:
      
         - Make vhost/scsi tag percpu_ida_alloc() use GFP_ATOMIC
         - Allow sess_cmd_map allocation failure fallback to use vzalloc
         - Fix COMPARE_AND_WRITE se_cmd->data_length bug with FILEIO backends
         - Fixes for COMPARE_AND_WRITE callback recursive failure OOPs + non
           zero scsi_status bug
         - Make iscsi-target do acknowledgement tag release from RX context
         - Setup iscsi-target with extra (cmdsn_depth / 2) percpu_ida tags
      
        Also included is a iscsi-target patch CC'ed for v3.10+ that avoids
        legacy wait_for_task=true release during fast-past StatSN
        acknowledgement, and two other SRP target related patches that address
        long-standing issues that are CC'ed for v3.3+.
      
        Extra thanks to Thomas Glanzmann for his testing feedback with
        COMPARE_AND_WRITE + EXTENDED_COPY VAAI logic"
