[patch 166/262] memblock: rename memblock_free to memblock_phys_free

Andrew Morton
2021-11-05T20:52:20Z

From: Mike Rapoport <rppt@linux.ibm.com>
Subject: memblock: rename memblock_free to memblock_phys_free

Since memblock_free() operates on a physical range, make its name reflect
it and rename it to memblock_phys_free(), so it will be a logical
counterpart to memblock_phys_alloc().

The callers are updated with the below semantic patch:

@@
expression addr;
expression size;
@@
- memblock_free(addr, size);
+ memblock_phys_free(addr, size);
