#     of: Drop superfluous ULL suffix for ~0
#     
#     There is no need to specify a "ULL" suffix for "all bits set": "~0" is
#     sufficient, and works regardless of type.  In fact adding the suffix
#     makes the code more fragile.
#     
#     Fixes: 48ab6d5d1f09 ("dma-mapping: fix 32-bit overflow with CONFIG_ARM_LPAE=n")
