* sched: remove printk_clock()Ingo Molnar2008-01-25
| | | | | | printk_clock() is obsolete - it has been replaced with cpu_clock(). Signed-off-by: Ingo Molnar <mingo@elte.hu>
* Driver core: change sysdev classes to use dynamic kobject namesKay Sievers2008-01-24
| | | | | | | | | | All kobjects require a dynamically allocated name now. We no longer need to keep track if the name is statically assigned, we can just unconditionally free() all kobject names on cleanup.

* driver core: make /sys/power a kobjectGreg Kroah-Hartman2008-01-24

* kset: convert /sys/power to use kset_createGreg Kroah-Hartman2008-01-24
| | | | | | | | | | | | | | Dynamically create the kset instead of declaring it statically. We also rename power_subsys to power_kset to catch all users of the variable and we properly export it so that people don't have to guess that it really is present in the system. The pseries code is wierd, why is it createing /sys/power if CONFIG_PM is disabled? Oh well, stupid big boxes ignoring config options...

* Fix ARM profiling/instrumentation configurationLinus Torvalds2008-01-15
| | | | | | | | | | | | | | | | | | | Commit 09cadedbdc01f1a4bea1f427d4fb4642eaa19da9 ("Combine instrumentation menus in kernel/Kconfig.instrumentation") broke ARM profiling support, since ARM has some extra Kconfig options and doesn't just use the common OPROFILE/KPROBES config options. Rather than just revert the thing outright, or add ARM-specific knowledge to the generic Kconfig.instrumentation file (where the only and whole point was to be generic, not too architecture-specific), this just makes ARM not use the generic version, since it doesn't suit it. So create an arm-specific version of Kconfig.instrumentation instead, and use that.

It however can produce spurious false negative if a processor exception occurs in the middle of the operation. Normally this is not a problem since cmpxchg is typically called in a loop until it succeeds to implement an atomic increment for example. Some use cases which don't involve a loop require that the operation be 100% reliable though. This patch changes the implementation so to reattempt the operation after an exception has occurred in the critical section rather than abort it. Here's a simple program to test the fix (don't use CONFIG_NO_HZ in your kernel as this depends on a sufficiently high interrupt rate): #include <stdio.h> typedef int (__kernel_cmpxchg_t)(int oldval, int newval, int *ptr); #define __kernel_cmpxchg (*(__kernel_cmpxchg_t *)0xffff0fc0) int main() { int i, x = 0; for (i = 0; i < 100000000; i++) { int v = x; if (__kernel_cmpxchg(v, v+1, &x)) printf("failed at %d: %d vs %d\n", i, v, x); } printf("done with %d vs %d\n", i, x); return 0; } Signed-off-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* | [ARM] pxa: fix one-shot timer modeRussell King2007-11-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One-shot timer mode on PXA has various bugs which prevent kernels build with NO_HZ enabled booting. They end up spinning on a permanently asserted timer interrupt because we don't properly clear it down - clearing the OIER bit does not stop the pending interrupt status. Fix this in the set_mode handler as well. Moreover, the code which sets the next expiry point may race with the hardware, and we might not set the match register sufficiently in the future. If we encounter that situation, return -ETIME so the generic time code retries.
