Linus Torvalds 9888428102 arm64 updates for 5.5: 
- ZONE_DMA32 initialisation fix when memblocks fall entirely within the
   first GB (used by ZONE_DMA in 5.5 for Raspberry Pi 4).
 
 - Couple of ftrace fixes following the FTRACE_WITH_REGS patchset.
 
 - access_ok() fix for the Tagged Address ABI when called from from a
   kernel thread (asynchronous I/O): the kthread does not have the TIF
   flags of the mm owner, so untag the user address unconditionally.
 
 - KVM compute_layout() called before the alternatives code patching.
 
 - Minor clean-ups.
