* MII: fix Kconfig dependencies for MIIJeff Kirsher2011-09-151-0/+1
| | | | | | | | | | | | | | | | MII Kconfig option is apart of the core networking drivers and by default NET_CORE is enabled so drivers selecting MII will have MII enabled as well. It was found using the randconfig option during testing, MII would be selected but NET_CORE could be disabled. This caused a dependency error. Resolved the dependency by selecting NET_CORE when MII is selected.

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) { <+...

* | cris: autoconvert trivial BKL usersArnd Bergmann2010-09-265-20/+23
|/ | | | | | | | | | | | | | | All uses of the big kernel lock in the cris architecture are for ioctl and open functions of character device drivers, which can be trivially converted to a per-driver mutex. Most of these are probably unnecessary, so it may make sense to audit them and eventually remove the extra mutex introduced by this patch.

* cris: autoconvert trivial BKL users to private mutexJesper Nilsson2010-08-042-8/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. 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> Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com>

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-303-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* | Add a bunch of cycle_kernel_lock() callsJonathan Corbet2008-06-202-1/+4
| | | | | | | | | | | | | | | | | | All of the open() functions which don't need the BKL on their face may still depend on its acquisition to serialize opens against driver initialization. So make those functions acquire then release the BKL to be on the safe side. Signed-off-by: Jonathan Corbet <corbet@lwn.net>
* | Add "no BKL needed" comments to several driversJonathan Corbet2008-06-201-1/+1
| | | | | | | | | | | | | | | | This documents the fact that somebody looked at the relevant open() functions and concluded that, due to their trivial nature, no locking was needed. Signed-off-by: Jonathan Corbet <corbet@lwn.net>

* CRIS v32: Change drivers/i2c.c locking.Jesper Nilsson2008-02-081-49/+12
| | | | | | | - Change spin_lock + local_irq_save into spin_lock_irqsave - Change spin_unlock + local_irq_restore into spin_unlock_irqrestore - Return ENOTTY if ioctl is not recognized as a cris ioctl. - Make init functions static.
* CRIS v32: Rewrite ARTPEC-3 gpio driver to avoid volatiles and general cleanup.Jesper Nilsson2008-02-081-174/+174
| | | | | | | | | | | | | | | | | | | | Changes as suggested by Andrew Morton, plus general cleanup to ease later consolidation of driver into machine common driver. - Correct parameter type of gpio_write to const char __user * - Remove volatile from the arrays of machine dependent registers, use readl and writel to access them instead. - Remove useless casts of void. - Use spin_lock_irqsave for locking. - Break gpio_write into smaller sub-functions. - Remove useless breaks after returns. - Don't perform any change in IO_CFG_WRITE_MODE if values are invalid. (previously values were set and then set to zero) - Change cast for copy_to_user to (void __user *) - Make file_operations gpio_fops static and const. - Make setget_output static. (However, it's still inline since the CRIS architecture is still not SMP, which makes the function small enough to inline)
* CRIS v32: Clean up nandflash.c for ARTPEC-3 and ETRAX FS.Jesper Nilsson2008-02-082-20/+24
| | | | | | | | | | Clean up issues noticed by Andrew Morton: - Use a combined struct for allocating the mtd_info and nand_chip structs instead of using anonymous memory as the example in Documentation/DocBook/mtdnand.tmpl - Use kzalloc instead of using kmalloc/memset(0) - Make crisv32_device_ready static.
* CRIS: Move ETRAX_AXISFLASHMAP to common Kconfig file.Jesper Nilsson2008-02-081-16/+0

* CRIS v32: Remove config ifdef around init function for drivers/sync_serial.cJesper Nilsson2008-02-081-5/+1
| | | | The init function should be defined always.
* CRIS v32: Remove drivers/gpio.c, now exists as machine specific file.Jesper Nilsson2008-02-081-765/+0
|
* CRIS v32: Update driver for RTC chip pcf8563.Jesper Nilsson2008-02-081-133/+163
| | | | | | | | | | | | - Moved all calls to register_chrdev to a function called by module_init. - Added mutex locking. - Added better error handling at start up. - Added BIN_TO_BCD of the month value before it is saved to the RTC. - Corrected the month value returned by pcf8563_readreg. - Cache the voltage low value at driver init so the battery status information does not get 'accidentally' cleared when setting the RTC time. - Removed obsolete CONFIG_ETRAX_RTC_READONLY - Voltage low ioctl():s RTC_VLOW_RD -> RTC_VL_READ, RTC_VLOW_SET -> RTC_VL_CLR
