I tried again, it applies well for me:

[root@...alhost linux-stable]# git checkout v4.14.47 -b 4.14.47
Checking out files: 100% (27111/27111), done.
Switched to a new branch '4.14.47'
[root@...alhost linux-stable]# git am 
/root/Downloads/4.14-1-4-powerpc-mm-slice-Remove-intermediate-bitmap-copy.patch 

Applying: powerpc/mm/slice: Remove intermediate bitmap copy
Applying: powerpc/mm/slice: create header files dedicated to slices
Applying: powerpc/mm/slice: Enhance for supporting PPC32
Applying: powerpc/mm/slice: Fix hugepage allocation at hint address on 8xx
[root@...alhost linux-stable]#

Is there any conflicting patch in the queue ?
What should I rebase on ?
