From: Mike Rapoport <rppt@xxxxxxxxxxxxx>
Rename memblock_free_ptr() to memblock_free() and use memblock_free()
when freeing a virtual pointer so that memblock_free() will be a
counterpart of memblock_alloc()
The callers are updated with the below semantic patch and manual addition
of (void *) casting to pointers that are represented by unsigned long
variables.
@@
identifier vaddr;
expression size;

(
- memblock_phys_free(__pa(vaddr), size);
+ memblock_free(vaddr, size);
|
- memblock_free_ptr(vaddr, size);
+ memblock_free(vaddr, size);
)
