[PATCH] suspend: fix suspend on single-CPU systems

2006-12-23T21:59:33+00:00

Clark Williams reported that suspend doesnt work on his laptop on
2.6.20-rc1-rt kernels. The bug was introduced by the following cleanup
commit:

 commit 112cecb2cc0e7341db92281ba04b26c41bb8146d
 Author: Siddha, Suresh B 
 Date:   Wed Dec 6 20:34:31 2006 -0800

    [PATCH] suspend: don't change cpus_allowed for task initiating the suspend

because with this change 'error' is not initialized to 0 anymore, if
there are no other online CPUs. (i.e. if the system is single-CPU).

the fix is the initialize it to 0. The really weird thing is that my
version of gcc does not warn about this non-initialized variable
situation ...

(also fix the kernel printk in the error branch, it was missing a
 newline)

[PATCH] Fix reparenting to the same thread group. (take 2)

2006-12-22T17:03:41+00:00

This patch fixes the case when we reparent to a different thread in the
same thread group.  This modifies the code so that we do not send
signals and do not change the signal to send to SIGCHLD unless we have
change the thread group of our parents.  It also suppresses sending
pdeath_sig in this cas as well since the result of geppid doesn't
change.

Thanks to Oleg for spotting my bug of only fixing this for non-ptraced
tasks.

[PATCH] fdtable: Provide free_fdtable() wrapper

2006-12-22T16:55:50+00:00

Christoph Hellwig has expressed concerns that the recent fdtable changes
expose the details of the RCU methodology used to release no-longer-used
fdtable structures to the rest of the kernel.  The trivial patch below
addresses these concerns by introducing the appropriate free_fdtable()
calls, which simply wrap the release RCU usage.  Since free_fdtable() is a
one-liner, it makes sense to promote it to an inline helper.

[PATCH] genirq: fix irq flow handler uninstall

2006-12-22T16:55:48+00:00

The sanity check for no_irq_chip in __set_irq_hander() is unconditional on
both install and uninstall of an handler.  This triggers false warnings and
replaces no_irq_chip by dummy_irq_chip in the uninstall case.

Check only, when a real handler is installed.

[PATCH] sched: remove __cpuinitdata anotation to cpu_isolated_map

2006-12-22T16:55:47+00:00

The structure cpu_isolated_map is used not only during initialization.
Multi-core scheduler configuration changes and exclusive cpusets
use this during run time.  During setting of sched_mc_power_savings
 policy, this structure is accessed to update sched_domains.
