* sbus: autoconvert trivial BKL users to private mutexArnd Bergmann2010-07-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: David S.

* of: unify phandle name in struct device_nodeGrant Likely2010-01-28
| | | | | | | | | | | | | | | | | | | | | In struct device_node, the phandle is named 'linux_phandle' for PowerPC and MicroBlaze, and 'node' for SPARC. There is no good reason for the difference, it is just an artifact of the code diverging over a couple of years. This patch renames both to simply .phandle. Note: the .node also existed in PowerPC/MicroBlaze, but the only user seems to be arch/powerpc/platforms/powermac/pfunc_core.c. It doesn't look like the assignment between .linux_phandle and .node is significantly different enough to warrant the separate code paths unless ibm,phandle properties actually appear in Apple device trees. I think it is safe to eliminate the old .node property and use phandle everywhere. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.

* [PATCH] remove many unneeded #includes of sched.hTim Schmielau2007-02-14
| | | | | | | | | | | | | | | | | | | | | | | | After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

* [PATCH] mark struct file_operations const 6Arjan van de Ven2007-02-12
| | | | | | | | | | | 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.

* [OPENPROMIO]: Handle current_node being NULL correctly.David S. Miller2006-09-18
| | | | | | | | | | | | If the user tries to traverse to the next node of the last node, we get NULL in current_node and a zero phandle returned. That's fine, but if the user tries to obtain properties in that state, we try to dereference a NULL pointer in the downcall to the of_*() routines. So protect against that. Signed-off-by: David S.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
