      PM / Hibernate: Fix s2disk regression related to freezing workqueues · 181e9bde
      Rafael J. Wysocki 提交于
      Commit 2aede851
      
        PM / Hibernate: Freeze kernel threads after preallocating memory
      
      introduced a mechanism by which kernel threads were frozen after
      the preallocation of hibernate image memory to avoid problems with
      frozen kernel threads not responding to memory freeing requests.
      However, it overlooked the s2disk code path in which the
      SNAPSHOT_CREATE_IMAGE ioctl was run directly after SNAPSHOT_FREE,
      which caused freeze_workqueues_begin() to BUG(), because it saw
      that worqueues had been already frozen.
      
      Although in principle this issue might be addressed by removing
      the relevant BUG_ON() from freeze_workqueues_begin(), that would
      reintroduce the very problem that commit 2aede851
      attempted to avoid into that particular code path.  For this reason,
      to fix the issue at hand, introduce thaw_kernel_threads() and make
      the SNAPSHOT_FREE ioctl execute it.
      
      Special thanks to Srivatsa S. Bhat for detailed analysis of the
      problem.

      arm-soc fixes for 3.3-rc:
      
      AT91 needed reset fixes which resulted in some minor code refactoring,
      it also adds a feature-removal for one of their platforms for 3.4.
      The USB patches have been acked by Greg K-H.
      
      i.MX and ux500 both have some minor fixes, nothing controversial.
