Subject: [PATCH 3/3] memblock: cleanup memblock_free interface
From: Mike Rapoport <rppt@...ux.ibm.com>
For ages memblock_free() interface dealt with physical addresses even
despite the existence of memblock_alloc_xx() functions that return a
virtual pointer.
Introduce memblock_phys_free() for freeing physical ranges and repurpose
memblock_free() to free virtual pointers to make the following pairing
abundantly clear:
int memblock_phys_free(phys_addr_t base, phys_addr_t size);
phys_addr_t memblock_phys_alloc(phys_addr_t base, phys_addr_t size);
void *memblock_alloc(phys_addr_t size, phys_addr_t align);
void memblock_free(void *ptr, size_t size);
Replace intermediate memblock_free_ptr() with memblock_free() and drop
unnecessary aliases memblock_free_early() and memblock_free_early_nid().
