Hi, This is v10 of a series to convert the 8250 driver to an NBCON console, providing both threaded and atomic printing implementations. v9 of this series is here [0]. Note that v5 was pulled into the 6.14 merge window, but was then reverted before the 6.14-rc1 release due to kernel test robot problems. It turned out that the problems were related to general 8250 driver issues. Those issues have now been addressed mainline, paving the way for a second take at converting the 8250 driver to NBCON. The changes since v9: - In serial8250_fifo_wait_for_lsr_thre(), always exit the unsafe section, regardless of wait_for_lsr() results.
