2007-05-11lib/hexdumpRandy Dunlap
Based on ace_dump_mem() from Grant Likely for the Xilinx SystemACE CompactFlash interface. Add print_hex_dump() & hex_dumper() to lib/hexdump.c and linux/kernel.h. This patch adds the functions print_hex_dump() & hex_dumper(). print_hex_dump() can be used to perform a hex + ASCII dump of data to syslog, in an easily viewable format, thus providing a common text hex dump format. hex_dumper() provides a dump-to-memory function. It converts one "line" of output (16 bytes of input) at a time. Example usages: print_hex_dump(KERN_DEBUG, DUMP_PREFIX_ADDRESS, frame->data, frame->len); hex_dumper(frame->data, frame->len, linebuf, sizeof(linebuf)); Example output using %DUMP_PREFIX_OFFSET: 0009ab42: 40414243 44454647 48494a4b 4c4d4e4f-@ABCDEFG HIJKLMNO Example output using %DUMP_PREFIX_ADDRESS: ffffffff88089af0: 70717273 74757677 78797a7b 7c7d7e7f-pqrstuvw xyz{|}~.

2007-05-11[PATCH] audit signal recipientsAmy Griffis
When auditing syscalls that send signals, log the pid and security context for each target process. Optimize the data collection by adding a counter for signal-related rules, and avoiding allocating an aux struct unless we have more than one target process. For process groups, collect pid/context data in blocks of 16. Move the audit_signal_info() hook up in check_kill_permission() so we audit attempts where permission is denied.

2007-05-09Add suspend-related notifications for CPU hotplugRafael J. Wysocki
Since nonboot CPUs are now disabled after tasks and devices have been frozen and the CPU hotplug infrastructure is used for this purpose, we need special CPU hotplug notifications that will help the CPU-hotplug-aware subsystems distinguish normal CPU hotplug events from CPU hotplug events related to a system-wide suspend or resume operation in progress. This patch introduces such notifications and causes them to be used during suspend and resume transitions. It also changes all of the CPU-hotplug-aware subsystems to take these notifications into consideration (for now they are handled in the same way as the corresponding "normal" ones).

2007-05-08Move LOG_BUF_SHIFT to a more sensible placeAlistair John Strachan
Several people have observed that perhaps LOG_BUF_SHIFT should be in a more obvious place than under DEBUG_KERNEL. Under some circumstances (such as the PARISC architecture), DEBUG_KERNEL can increase kernel size, which is an undesirable trade off for something as trivial as increasing the kernel log buffer size. Instead, move LOG_BUF_SHIFT into "General Setup", so that people are more likely to be able to change it such a circumstance that the default buffer size is insufficient.

2007-05-08fix sscanf %n match at end of input stringJohannes Berg
I was playing with some code that sometimes got a string where a %n match should have been done where the input string ended, for example like this: sscanf("abc123", "abc%d%n", &a, &n); /* doesn't work */ sscanf("abc123a", "abc%d%n", &a, &n); /* works */ However, the scanf function in the kernel doesn't convert the %n in that case because it has already matched the complete input after %d and just completely stops matching then. This patch fixes that.

Remove the Kconfig selection of semaphore debugging from the ALPHA and FRV Kconfig files, and centralize it in lib/Kconfig.debug. There doesn't seem to be much point in letting individual architectures independently define the same Kconfig option when it can just as easily be put in a single Kconfig file and made dependent on a subset of architectures. that way, at least the option shows up in the same relative location in the menu each time.

2007-05-07blackfin architectureBryan Wu
This adds support for the Analog Devices Blackfin processor architecture, and currently supports the BF533, BF532, BF531, BF537, BF536, BF534, and BF561 (Dual Core) devices, with a variety of development platforms including those avaliable from Analog Devices (BF533-EZKit, BF533-STAMP, BF537-STAMP, BF561-EZKIT), and Bluetechnix! Tinyboards. The Blackfin architecture was jointly developed by Intel and Analog Devices Inc. (ADI) as the Micro Signal Architecture (MSA) core and introduced it in December of 2000. Since then ADI has put this core into its Blackfin processor family of devices. The Blackfin core has the advantages of a clean, orthogonal,RISC-like microprocessor instruction set. It combines a dual-MAC (Multiply/Accumulate), state-of-the-art signal processing engine and single-instruction, multiple-data (SIMD) multimedia capabilities into a single instruction-set architecture. The Blackfin architecture, including the instruction set, is described by the ADSP-BF53x/BF56x Blackfin Processor Programming Reference http://blackfin.uclinux.org/gf/download/frsrelease/29/2549/Blackfin_PRM.pdf The Blackfin processor is already supported by major releases of gcc, and there are binary and source rpms/tarballs for many architectures at: http://blackfin.uclinux.org/gf/project/toolchain/frs There is complete documentation, including "getting started" guides available at: http://docs.blackfin.uclinux.org/ which provides links to the sources and patches you will need in order to set up a cross-compiling environment for bfin-linux-uclibc This patch, as well as the other patches (toolchain, distribution, uClibc) are actively supported by Analog Devices Inc, at: http://blackfin.uclinux.org/ We have tested this on LTP, and our test plan (including pass/fails) can be found at: http://docs.blackfin.uclinux.org/doku.php?id=testing_the_linux_kernel [m.kozlowski@tuxland.pl: balance parenthesis in blackfin header files] Signed-off-by: Bryan Wu <bryan.wu@analog.com> Signed-off-by: Mariusz Kozlowski <m.kozlowski@tuxland.pl> Signed-off-by: Aubrey Li <aubrey.li@analog.com> Signed-off-by: Jie Zhang <jie.zhang@analog.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-05-07Introduce CONFIG_HAS_DMAHeiko Carstens
Architectures that don't support DMA can say so by adding a config NO_DMA to their Kconfig file. This will prevent compilation of some dma specific driver code. Also dma-mapping-broken.h isn't needed anymore on at least s390. This avoids compilation and linking of otherwise dead/broken code. Other architectures that include dma-mapping-broken.h are arm26, h8300, m68k, m68knommu and v850. If these could be converted as well we could get rid of the header file.

2007-05-07Safer nr_node_ids and nr_node_ids determination and initial valuesChristoph Lameter
The nr_cpu_ids value is currently only calculated in smp_init. However, it may be needed before (SLUB needs it on kmem_cache_init!) and other kernel components may also want to allocate dynamically sized per cpu array before smp_init. So move the determination of possible cpus into sched_init() where we already loop over all possible cpus early in boot. Also initialize both nr_node_ids and nr_cpu_ids with the highest value they could take. If we have accidental users before these values are determined then the current valud of 0 may cause too small per cpu and per node arrays to be allocated. If it is set to the maximum possible then we only waste some memory for early boot users.

2007-05-04iomap: make the default iomap functions fail softerLinus Torvalds
We used to BUG_ON() for a badly mapped IO port, which is certainly correct, but actually made it harder to debug the case where the ATA drivers had incorrectly mapped a nonconnected ATA port. So make badly mapped ports trigger a WARN_ON(), and throw the IO away instead (and return all ones for reads). For things like broken driver initialization - which is the most likely cause anyway - that should mean that the machine comes up and is usable (at least that was the case for the ATA breakage that triggered this patch). It tends to be a whole lot easier to do a "dmesg" on a working machine than to try to capture logs off a dead one. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-04-27kref: fix CPU ordering with respect to krefsOliver Neukum
some atomic operations are only atomic, not ordered. Thus a CPU is allowed to reorder memory references to an object to before the reference is obtained. This fixes it. Signed-off-by: Oliver Neukum <oneukum@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2007-04-27driver core: fix namespace issue with devices assigned to classesKay Sievers
- uses a kset in "struct class" to keep track of all directories belonging to this class - merges with the /sys/devices/virtual logic. - removes the namespace-dir if the last member of that class leaves the directory. There may be locking or refcounting fixes left, I stopped when it seemed to work with network and sound modules. :) From: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
