2600  mutex_lock( & dev_lock)
2601  setup_opal_dev(dev)
2603  bit_set等于ls64 - find last set bit in a 64-bit word*@x: the word to search* This is defined in a similar way as the libc and compiler builtin* ffsll, but returns the position of the most significant set bit减1
2605  当:bit_set恒等于OPAL_READ_TABLE
2606  ret等于opal_read_table(dev, rw_tbl)
2607  退出
2608  当:bit_set恒等于OPAL_WRITE_TABLE
2609  ret等于opal_write_table(dev, rw_tbl)
2610  退出
2611  默认
2612  pr_debug("Invalid bit set in the flag (%016llx).\n", flags)
