2006-12-13[PATCH] Optimize D-cache alias handling on forkRalf Baechle
Virtually index, physically tagged cache architectures can get away without cache flushing when forking. This patch adds a new cache flushing function flush_cache_dup_mm(struct mm_struct *) which for the moment I've implemented to do the same thing on all architectures except on MIPS where it's a no-op.

2006-12-13[PATCH] debug: add sysrq_always_enabled boot optionIngo Molnar
Most distributions enable sysrq support but set it to 0 by default. Add a sysrq_always_enabled boot option to always-enable sysrq keys. Useful for debugging - without having to modify the disribution's config files (which might not be possible if the kernel is on a live CD, etc.). Also, while at it, clean up the sysrq interfaces.

Add support for the Fintek F71872F/FG Super-I/O chip. It is basically the same as the Fintek F71805F/FG as far as hardware monitoring is concerned, with two additional internal voltages monitored (VSB and battery), and 6 VID inputs (not yet supported.) To make things a bit more confusing, two of the voltage input pins (in4 and in8) can be used for other functions. The driver reads the pin configuration from the Super-I/O configuration space to decide whether it must create interface files for these inputs or not. Many thanks to Nikolay Derkach for testing the early iterations of this code and reporting bugs. Signed-off-by: Jean Delvare <khali@linux-fr.org>

2006-12-10[PATCH] spi: stabilize PIO mode transfers on PXA2xx systemsStephen Street
Stabilize PIO mode transfers against a range of word sizes and FIFO thresholds and fixes word size setup/override issues. 1) 16 and 32 bit DMA/PIO transfers broken due to timing differences. 2) Potential for bad transfer counts due to transfer size assumptions. 3) Setup function broken is multiple ways. 4) Per transfer bit_per_word changes break DMA setup in pump_tranfers. 5) False positive timeout are not errors. 6) Changes in pxa2xx_spi_chip not effective in calls to setup. 7) Timeout scaling wrong for PXA255 NSSP. 8) Driver leaks memory while busy during unloading. Known issues: SPI_CS_HIGH and SPI_LSB_FIRST settings in struct spi_device are not handled. Testing: This patch has been test against the "random length, random bits/word, random data (verified on loopback) and stepped baud rate by octaves (3.6MHz to 115kHz)" test. It is robust in PIO mode, using any combination of tx and rx thresholds, and also in DMA mode (which internally computes the thresholds). Much thanks to Ned Forrester for exhaustive reviews, fixes and testing. The driver is substantially better for his efforts.

2006-12-08[PATCH] fault injection: stacktrace filteringAkinobu Mita
This patch provides stacktrace filtering feature. The stacktrace filter allows failing only for the caller you are interested in. For example someone may want to inject kmalloc() failures into only e100 module. they want to inject not only direct kmalloc() call, but also indirect allocation, too. - e100_poll --> netif_receive_skb --> packet_rcv_spkt --> skb_clone --> kmem_cache_alloc This patch enables to detect function calls like this by stacktrace and inject failures. The script Documentaion/fault-injection/failmodule.sh helps it. The range of text section of loaded e100 is expected to be [/sys/module/e100/sections/.text, /sys/module/e100/sections/.exit.text) So failmodule.sh stores these values into /debug/failslab/address-start and /debug/failslab/address-end. The maximum stacktrace depth is specified by /debug/failslab/stacktrace-depth. Please see the example that demonstrates how to inject slab allocation failures only for a specific module in Documentation/fault-injection/fault-injection.txt [dwm@meer.net: reject failure if any caller lies within specified range] Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Signed-off-by: Don Mullis <dwm@meer.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

This patch set provides some fault-injection capabilities. - kmalloc() failures - alloc_pages() failures - disk IO errors We can see what really happens if those failures happen. In order to enable these fault-injection capabilities: 1. Enable relevant config options (CONFIG_FAILSLAB, CONFIG_PAGE_ALLOC, CONFIG_MAKE_REQUEST) and if you want to configure them via debugfs, enable CONFIG_FAULT_INJECTION_DEBUG_FS. 2. Build and boot with this kernel 3. Configure fault-injection capabilities behavior by boot option or debugfs - Boot option failslab= fail_page_alloc= fail_make_request= - Debugfs /debug/failslab/* /debug/fail_page_alloc/* /debug/fail_make_request/* Please refer to the Documentation/fault-injection/fault-injection.txt for details. 4.

2006-12-07ieee1394: conditionally export ieee1394_bus_typeStefan Richter
Follow-up to patch "Consolidate driver registering": Since I plan the lifetime of Linux 2.6.20 to be the deprecation phase of CONFIG_IEEE1394_EXPORT_FULL_API, it seems fair to keep all previously exported symbols available with this option until this phase is over.

2006-12-07ieee1394: schedule *_oui sysfs attributes for removalStefan Richter
There is no manpower available to reform oui.db into a library for use in more kernel subsystems. The low ratio of usefulness to size and the occasional need to update oui.db from IEEE's official list suggest to drop oui.db. I plan to make a userspace script available which translates the remaining numeric sysfs attributes to names of organizations. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
