For example: memblock_reserve: [0x0000009e7e8000-0x0000009e7ed000] _memblock_early_alloc_try_nid_nopanic+0xfc/0x12c The 0x0000009e7ed000 is displayed instead of 0x0000009e7ecfff Hence, correct this by changing formula used to calculate upper memory boundary to (u64)base + size - 1 instead of (u64)base + size everywhere in the debug messages.
