Subject: powerpc/powernv: Rename alloc_m64_pe() to reserve_m64_pe()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5ef73567813cddabe5fd1105e915be0851820f4f;p=linux-beck.git

powerpc/powernv: Rename alloc_m64_pe() to reserve_m64_pe()

The patch renames alloc_m64_pe() to reserve_m64_pe() to reflect
its real usage: We reserve PE numbers for M64 segments in advance
and then pick up the reserved PE numbers when building the mapping
between PE numbers and M64 segments.
