2007-02-12[PATCH] mark struct file_operations const 3Arjan van de Ven
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

2006-10-04[WATCHDOG] w83697hf/hg WDT driver - patch 16Samuel Tardieu
This is patch 16 in the series of patches that converts Marcus Junker's w83697hf watchdog driver to Samuel Tardieau's w83697hf/hg watchdog driver. This patch contains following changes: - Add copyright notice for Samuel Tardieu also. This is the last patch in this series. The original description for Samuel's driver was: driver for the Winbond W83697HF/W83697HG watchdog timer The Winbond SuperIO W83697HF/HG includes a watchdog that can count from 1 to 255 seconds (or minutes). This drivers allows the seconds mode to be used. It exposes a standard /dev/watchdog interface. This chip is currently being used on some motherboards designed by VIA. By default, the module looks for a chip at I/O port 0x2e. The chip can be configured to be at 0x4e on some motherboards, the address can be chosen using the wdt_io module parameter. Using 0 will try to autodetect the address. Signed-off-by: Samuel Tardieu <sam@rfc1149.net> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
2006-10-04[WATCHDOG] w83697hf/hg WDT driver - patch 15Samuel Tardieu
This is patch 15 in the series of patches that converts Marcus Junker's w83697hf watchdog driver to Samuel Tardieau's w83697hf/hg watchdog driver. This patch contains following changes: - Clean-up initialization code - part 2: * the line reading "set second mode & disable keyboard ..." is plain wrong, the register being manipulated (CRF4) is the counter itself, not the control byte (CRF3) -- looks like it has been copied from another driver. * I think garbage is being written in CRF3 (the control word) as the timeout value is being stored in this register (such as 60 for 60 seconds). * We only want to set pin 119 to WDTO# mode and leave the rest of CR29 like it is. * Set count mode to seconds and not minutes.
