Revert "memory-hotplug: add 0x prefix to HEX block_size_bytes"

2010-04-09T17:05:33Z

This reverts commit ba168fc37dea145deeb8fa9e7e71c748d2e00d74. It changes user-visible sysfs interfaces, and breaks some existing user space applications which apparently rely on the fact that the output does not contain the "0x" prefix.

nodemask: include slab.h from drivers/base/node.c

2010-04-06T21:41:41Z

NODEMASK_ALLOC/FREE are mapped to kmalloc/free if NODES_SHIFT > 8. Among its several users, drivers/base/node.c wasn't including slab.h leading to build failure if NODES_SHIFT > 8. Include slab.h from drivers/base/node.c. This isn't an ideal solution but including slab.h directly from nodemask.h is not an option because nodemask.h gets included everywhere. For now, make it work by including slab.h from its users. Signed-off-by: Tejun Heo Reported-by: Ingo Molnar

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h

2010-03-30T13:02:32Z

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.

[SCSI] attirbute_container: Initialize sysfs attributes with sysfs_attr_init

2010-03-27T19:15:24Z

All of the SCSI transport classes are suddenly spitting lockdep warnings. According to Eric Biderman this is because lockdep needs static initialisers and the attribute container way of doing things end up with dynamic sysfs attributes. Fix this by calling sysfs_attr_init which sets the lockdep key correctly. Tested-by: Christof Schmitt Signed-off-by: James Bottomley

power: support _noirq actions on device types and classes

2010-03-24T10:00:02Z

The new-style dev_pm_ops provide callbacks for both IRQs enabled and disabled. However, the _noirq variants were only called for buses registered with a device, not for classes and types. In order to properly use dev_pm_ops in class pcmcia_socket_class, support _noirq actions also on classes and types. Signed-off-by: Dominik Brodowski Acked-by: Rafael J. Wysocki

driver core: numa: fix BUILD_BUG_ON for node_read_distance

2010-03-19T14:12:22Z

node_read_distance() has a BUILD_BUG_ON() to prevent buffer overruns when the number of nodes printed will exceed the buffer length. Each node only needs four chars: three for distance (maximum distance is 255) and one for a seperating space or a trailing newline.
