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) { <+...

2010-10-14powerpc/watchdog: Make default timeout for Book-E watchdog a Kconfig optionTimur Tabi
The PowerPC Book-E watchdog driver (booke_wdt.c) defines a default timeout value in the code based on whether it's a Freescale Book-E part of not. Instead of having hard-coded values in the driver, make it a Kconfig option. As newer chips gets faster, the current default values become less appropriate, since the timeout sometimes occurs before the kernel finishes booting. Making the value a Kconfig option allows BSPs to configure a new value without requiring the wdt_period command-line parameter to be set.

2010-10-05drivers: autoconvert trivial BKL users to private mutexArnd Bergmann
All these files use the big kernel lock in a trivial way to serialize their private file operations, typically resulting from an earlier semi-automatic pushdown from VFS. None of these drivers appears to want to lock against other code, and they all use the BKL as the top-level lock in their file operations, meaning that there is no lock-order inversion problem. Consequently, we can remove the BKL completely, replacing it with a per-file mutex in every case. Using a scripted approach means we can avoid typos. These drivers do not seem to be under active maintainance from my brief investigation. Apologies to those maintainers that I have missed. file=$1 name=$2 if grep -q lock_kernel ${file} ; then if grep -q 'include.*linux.mutex.h' ${file} ; then sed -i '/include.*<linux\/smp_lock.h>/d' ${file} else sed -i 's/include.*<linux\/smp_lock.h>.*$/include <linux\/mutex.h>/g' ${file} fi sed -i ${file} \ -e "/^#include.*linux.mutex.h/,$ { 1,/^\(static\|int\|long\)/ { /^\(static\|int\|long\)/istatic DEFINE_MUTEX(${name}_mutex); } }" \ -e "s/\(un\)*lock_kernel\>[ ]*()/mutex_\1lock(\&${name}_mutex)/g" \ -e '/[ ]*cycle_kernel_lock();/d' else sed -i -e '/include.*\<smp_lock.h\>/d' ${file} \ -e '/cycle_kernel_lock()/d' fi Signed-off-by: Arnd Bergmann <arnd@arndb.de>

The OCTEON is a MIPS64 based SOC family with an on chip watchdog unit. The driver is split into two source files one for the C code and one for assembly. Assembly is needed to handle the NMI and then print the machine state before the reboot is triggered.

2010-07-24of/platform: remove all of_bus_type and of_platform_bus_type referencesGrant Likely
Both of_bus_type and of_platform_bus_type are just #define aliases for the platform bus. This patch removes all references to them and switches to the of_register_platform_driver()/of_unregister_platform_driver() API for registering. Subsequent patches will convert each user of of_register_platform_driver() into plain platform_drivers without the of_platform_driver shim. At which point the of_register_platform_driver()/of_unregister_platform_driver() functions can be removed. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.

2010-06-28sparc/of: Move of_device fields into struct pdev_archdataGrant Likely
This patch moves SPARC architecture specific data members out of struct of_device and into the pdev_archdata structure. The reason for this change is to unify the struct of_device definition amongst all the architectures. It also remvoes the .sysdata, .slot, .portid and .clock_freq properties because they aren't actually used by anything. A subsequent patch will replace struct of_device entirely with struct platform_device and the of_platform support code will share common routines with the platform bus (but the bus instances themselves can remain separate). This patch also adds 'struct resources *resource' and num_resources to match the fields defined in struct platform_device. After this change, 'struct platform_device' can be used as a drop-in replacement for 'struct of_platform'. This change is in preparation for merging the of_platform_bus_type with the platform_bus_type. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.

2010-05-27mfd: Change rdc321x resources flags to IORESOURCE_IOFlorian Fainelli
The rdc321x southbridge PCI device has no MEM PCI resources that we could pass to mfd_add_devices. Since 33254dd5, mfd_add_device checks for the mem_base argument that we set to NULL. Changing the resources passed to our MFD cells from IORESOURCE_MEM to IORESOURCE_IO fixes that. Since we use those resources as offsets to the PCI configuration space base address of the southbridge device this is also more adequate.

The RDC321x MFD southbridge driver will pass a reference to the southbridge PCI device which should be used by the watchdog driver for its operations. This patch converts the watchdog driver to use the pci_dev pointer and make use of the base register resource which is passed along with the platform device.

Also the timeout values in the module description and error message were clarified. And the _STS registers are 16 bit instead of 8 bit.
