#     Merge branch 'hch' (maccess patches from Christoph Hellwig)
#     
#     Merge non-faulting memory access cleanups from Christoph Hellwig:
#      "Andrew and I decided to drop the patches implementing your suggested
#       rename of the probe_kernel_* and probe_user_* helpers from -mm as
#       there were way to many conflicts.
#     
#       After -rc1 might be a good time for this as all the conflicts are
#       resolved now"
#     
#     This also adds a type safety checking patch on top of the renaming
#     series to make the subtle behavioral difference between 'get_user()' and
#     'get_kernel_nofault()' less potentially dangerous and surprising.
#     
#     * emailed patches from Christoph Hellwig <hch@lst.de>:
#       maccess: make get_kernel_nofault() check for minimal type compatibility
#       maccess: rename probe_kernel_address to get_kernel_nofault
#       maccess: rename probe_user_{read,write} to copy_{from,to}_user_nofault
#       maccess: rename probe_kernel_{read,write} to copy_{from,to}_kernel_nofault
