    memblock: memblock_phys_alloc_try_nid(): don't panic · 33755574
    Mike Rapoport authored
    The memblock_phys_alloc_try_nid() function tries to allocate memory from
    the requested node and then falls back to allocation from any node in
    the system.  The memblock_alloc_base() fallback used by this function
    panics if the allocation fails.
    
    Replace the memblock_alloc_base() fallback with the direct call to
    memblock_alloc_range_nid() and update the memblock_phys_alloc_try_nid()
    callers to check the returned value and panic in case of error.
