* 'for-linus' of git://www.jni.nu/cris: CRIS: Add paths for CRISv10 serial driver CRIS: Fix RS485 delay handling. Add missing "struct" to in sizeof.
2010-10-28CRIS: Fix RS485 delay handling.Jesper Nilsson
Very recently, the RS485 interface has been fixed by adding two further fields (see commit 1b6331848b69d1ed165a6bdc75c4046d68767563). Check the value of the flag SER_RS485_RTS_BEFORE_SEND before delaying. Signed-off-by: Claudio Scordino <claudio@evidence.eu.com> Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com>

2010-10-22serial8250: ratelimit "too much work" errorDaniel Drake
Running a serial console, if too many kernel messages are generated within a short time causing a lot of serial I/O, the 8250 driver will generate another kernel message reporting this, which just adds to the I/O. It has a cascading effect and quickly results the system being brought to its knees by a flood of "too much work" messages. Ratelimit the error message to avoid this.

The .start_tx callback (imx_start_tx here) isn't only called when the buffer is non-empty. E.g. after resume or when handshaking is enabled and the other side starts to signal being ready. So check for an empty puffer already before sending the first character. This prevents sending out stale (or uninitialised) data.

2010-10-22serial-core: restore termios settings when resume console portsJason Wang
The commit 4547be7 rewrites suspend and resume functions. According to this rewrite, when a serial port is a printk console device and can suspend(without set no_console_suspend flag), it will definitely call set_termios function during its resume, but parameter termios isn't initialized, this will pass an unpredictable config to the serial port. If this serial port is not a userspace opened tty device , a suspend and resume action will make this serial port unusable. I.E. ttyS0 is a printk console device, ttyS1 or keyboard+display is userspace tty device, a suspend/resume action will make ttyS0 unusable. If a serial port is both a printk console device and an opened tty device, this issue can be overcome because it will call set_termios again with the correct parameter in the uart_change_speed function. Refer to the deleted content of commit 4547be7, revert parts relate to restore settings into parameter termios. It is safe because if a serial port is a printk console only device, the only meaningful field in termios is c_cflag and its old config is saved in uport->cons->cflag, if this port is also an opened tty device, it will clear uport->cons->cflag in the uart_open and the old config is saved in tty->termios.

2010-10-22serial-core: skip call set_termios/console_start when no_console_suspendJason Wang
The commit 4547be7 rewrites suspend and resume functions, this introduces a problem on the OMAP3EVM platoform. when the kernel boots with no_console_suspend and we suspend the kernel, then resume it, the serial console will be not usable. This problem should be common for all platforms. The cause for this problem is that when enter suspend, if we choose no_console_suspend, the console_stop will be skiped. But in resume function, the console port will be set to uninitialized state by calling set_termios function and the console_start is called without checking whether the no_console_suspend is set, Now fix it.

2010-10-15llseek: automatically add .llseek fopArnd Bergmann
All file_operations should get a .llseek operation so we can make nonseekable_open the default for future file operations without a .llseek pointer. The three cases that we can automatically detect are no_llseek, seq_lseek and default_llseek. For cases where we can we can automatically prove that the file offset is always ignored, we use noop_llseek, which maintains the current behavior of not returning an error from a seek. New drivers should normally not use noop_llseek but instead use no_llseek and call nonseekable_open at open time. Existing drivers can be converted to do the same when the maintainer knows for certain that no user code relies on calling seek on the device file. The generated code is often incorrectly indented and right now contains comments that clarify for each added line why a specific variant was chosen. In the version that gets submitted upstream, the comments will be gone and I will manually fix the indentation, because there does not seem to be a way to do that using coccinelle. Some amount of new code is currently sitting in linux-next that should get the same modifications, which I will do at the end of the merge window. Many thanks to Julia Lawall for helping me learn to write a semantic patch that does all this. ===== begin semantic patch ===== // This adds an llseek= method to all file operations, // as a preparation for making no_llseek the default. // // The rules are // - use no_llseek explicitly if we do nonseekable_open // - use seq_lseek for sequential files // - use default_llseek if we know we access f_pos // - use noop_llseek if we know we don't access f_pos, // but we still want to allow users to call lseek // @ open1 exists @ identifier nested_open; @@ nested_open(...) { <+... nonseekable_open(...) ...+> } @ open exists@ identifier open_f; identifier i, f; identifier open1.nested_open; @@ int open_f(struct inode *i, struct file *f) { <+...

The speed and clock of the serial ports is retrieved from the device tree in both the PowerPC legacy serial code and the Open Firmware serial driver, therefore they need to handle the fact that the device tree is always big endian, while the CPU may not be.
