Subject: [PATCH] powerpc/mm/slb: Move comment next to the code it's referring
 to

References: bsc#1048914, bsc#1054026
Patch-mainline: v4.14-rc1
Git-commit: b5048de04b32104140e5b251005404c3e0d03ccd

There is a comment in slb_allocate() referring to the load of
paca->vmalloc_sllp, but it's several lines prior in the assembly.
We're about to change this code, and we want to add another comment,
so move the comment immediately prior to the instruction it's talking
about.
