Continuing the work started in 411f0f3e ... This enables code with a dma path, that compiles away, to build without requiring additional code factoring. It also prevents code that calls dma_alloc_coherent and dma_free_coherent from linking whereas previously the code would hit a BUG() at run time. Finally, it allows archs that set !HAS_DMA to delete their asm/dma-mapping.h file.

Allow printk_time to be enabled or disabled at boot time. Previously it could be enabled only, but not disabled. Change printk_time from an int to a bool since that's what it is. Make its logical (exposed) name just be "time" (was "printk_time"). Note: Changes kernel boot option syntax from "time" to "printk.time=value". Since printk_time is declared as a module_param, it can also be changed at run-time by modifying /sys/module/printk/parameters/time to a value of 1/Y/y to enabled it or 0/N/n to disable it. Since printk_time is declared as a module_param, its value can also be set at boot-time by using linux printk.time=<bool> If the "time" boot option is used, print a message that it is deprecated and will be removed. Note its planned removal in feature-removal-schedule.txt. Signed-off-by:

Fix and cleanup example scripts in fault injection documentation. 1. Eliminate broken oops() shell function. 2. Fold failcmd.sh and failmodule.sh into example scripts. It makes the example scripts work independent of current working directory. 3. Set "space" parameter to 0 to start injecting errors immediately. 4. Use /sys/module/<modulename>/sections/.data as upper bound of .text section. Because some module doesn't have .exit.text section. Signed-off-by:

Limiting smaller allocation failures by fault injection helps to find real possible bugs. Because higher order allocations are likely to fail and zero-order allocations are not likely to fail. This patch adds min-order parameter to fail_page_alloc. It specifies the minimum page allocation order to be injected failures. Signed-off-by:

Add the print-fatal-signals=1 boot option and the /proc/sys/kernel/print-fatal-signals runtime switch. This feature prints some minimal information about userspace segfaults to the kernel console. This is useful to find early bootup bugs where userspace debugging is very hard. Defaults to off. [akpm@linux-foundation.org: Don't add new sysctl numbers] Signed-off-by:

Some users have been having problems with utilities like cp or dd dumping core when they try to copy a file that's too large for the destination filesystem (typically, > 4gb). Apparently, some defunct standards required SIGXFSZ to be sent in such circumstances, but SUS only requires/allows it for when a written file exceeds the process's resource limits. I'd like to limit SIGXFSZs to the bare minimum required by SUS. Patch sent per http://lkml.org/lkml/2007/4/10/302Signed-off-by:

This patch is using mmap()'s randomization functionality in such a way that it maps the main executable of (specially compiled/linked -pie/-fpie) ET_DYN binaries onto a random address (in cases in which mmap() is allowed to perform a randomization).

fs/isofs/* had a bunch of CodingStyle issues. * Indentation was a mix of spaces and tabs * "int * foo" instead of "int *foo" * "while ( foo )" instead of "while (foo)" * if (foo) blah; on one line instead of two * Missing printk KERN_ levels * lots of trailing whitespace * lines >80 columns changed to wrap. * Unnecessary prototype removed by shuffling code order in C file. Should be no functional changes other than slight size increase due to printk changes. Further improvement possible, but this is a start.. Signed-off-by:
