-Subject: [PATCH 045/134] serial: pch: Use port lock wrappers
-Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/6.6/older/patches-6.6.7-rt18.tar.xz
-
-When a serial port is used for kernel console output, then all
-modifications to the UART registers which are done from other contexts,
-e.g. getty, termios, are interference points for the kernel console.
-
-So far this has been ignored and the printk output is based on the
-principle of hope. The rework of the console infrastructure which aims to
-support threaded and atomic consoles, requires to mark sections which
-modify the UART registers as unsafe. This allows the atomic write function
-to make informed decisions and eventually to restore operational state. It
-also allows to prevent the regular UART code from modifying UART registers
-while printk output is in progress.
-
-All modifications of UART registers are guarded by the UART port lock,
-which provides an obvious synchronization point with the console
-infrastructure.
-
-To avoid adding this functionality to all UART drivers, wrap the
-spin_[un]lock*() invocations for uart_port::lock into helper functions
-which just contain the spin_[un]lock*() invocations for now. In a
-subsequent step these helpers will gain the console synchronization
-mechanisms.
-
-Converted with coccinelle. No functional change.
