    arch: simplify several early memory allocations · b63a07d6
    Mike Rapoport authored
    There are several early memory allocations in arch/ code that use
    memblock_phys_alloc() to allocate memory, convert the returned physical
    address to the virtual address and then set the allocated memory to
    zero.
    
    Exactly the same behaviour can be achieved simply by calling
    memblock_alloc(): it allocates the memory in the same way as
    memblock_phys_alloc(), then it performs the phys_to_virt() conversion
    and clears the allocated memory.
    
    Replace the longer sequence with a simpler call to memblock_alloc().
