         - Don't return a garbage screen info when EFI framebuffer is not
           available
      
         - Make the early EFI console work properly with wider fonts instead
           of drawing garbage
      
         - Prevent a memory buffer leak in allocate_e820()
      
         - Print the firmware error record properly so it can be decoded by
           users
      
         - Fix a symbol clash in the host tool build which only happens with
           newer compilers.
      
         - Add a missing check for the event log version of TPM which caused
           boot failures on several Dell systems due to an attempt to decode
           SHA-1 format with the crypto agile algorithm"

      ASSERT_RTNL() warning will be triggered - which happens now during System

                  |- ASSERT_RTNL();
      
      Hence, fix it by surrounding cpsw_ndo_stop() by rtnl_lock/unlock() calls.

      net: phy: mscc: fix initialization of the MACsec protocol mode · 0ddfee1f
      Antoine Tenart authored
      At the very end of the MACsec block initialization in the MSCC PHY
      driver, the MACsec "protocol mode" is set. This setting should be set
      based on the PHY id within the package, as the bank used to access the
      register used depends on this. This was not done correctly, and only the
      first bank was used leading to the two upper PHYs being unstable when
      using the VSC8584. This patch fixes it.

      net: stmmac: don't attach interface until resume finishes · 31096c3e
      Leon Yu authored
      Commit 14b41a29 ("net: stmmac: Delete txtimer in suspend") was the
      first attempt to fix a race between mod_timer() and setup_timer()
      during stmmac_resume(). However the issue still exists as the commit
      only addressed half of the issue.
      
      Same race can still happen as stmmac_resume() re-attaches interface
      way too early - even before hardware is fully initialized.  Worse,
      doing so allows network traffic to restart and stmmac_tx_timer_arm()
      being called in the middle of stmmac_resume(), which re-init tx timers
      in stmmac_init_coalesce().  timer_list will be corrupted and system
      crashes as a result of race between mod_timer() and setup_timer().

      sparc32: fix page table traversal in srmmu_nocache_init() · 0cfc8a8d
      Mike Rapoport authored
      The srmmu_nocache_init() uses __nocache_fix() macro to add an offset to
      page table entry to access srmmu_nocache_pool.
      
      But since sparc32 has only three actual page table levels, pgd, p4d and
      pud are essentially the same thing and pgd_offset() and p4d_offset() are
      no-ops, the __nocache_fix() should be done only at PUD level.
      
      Remove __nocache_fix() for p4d_offset() and pud_offset() and keep it
      only for PUD and lower levels.
