This patch adds an algorithm to push extra RT tasks off a run queue to

When more than one RT task is added to a run queue, this algorithm takes

Since we now take an active approach to load balancing, we don't need to

Noticed that CONFIG_ACPI_PROCFS and CONFIG_ACPI_PROC_EVENT are
indicated as depreciated. Does that imply a new acpid is needed to
access /sys instead?
Thanks,
Jeff.

fs/cifs/cifssmb.c - get rid of couple of unused function warnings which
show up when CONFIG_CIFS_EXPERIMENTAL is not defined - wrap them in
#ifdef CONFIG_CIFS_EXPERIMENTAL. Patch against current git.

This set of two patches look ok by me, but I'd like sign-offs.. Also, were
they tested and found to fix the problem by Sami?

Umm. This is why we write things like

What is the proc_base_stuff[] nonsense about? AFAICS, that

Thanks all for the answers.
I could load by specifying lower amount of memory but on the newer
platform(does not exist), some of the existing components will
not exist while some newer ones will be added. So, it won't be
entirely accurate but I could still get some idea by trying
it out.
Thanks,
Introduce new __holds() macro to tell sparse it's OK to drop and then
reacquire a lock within a function. Use it in scsi_request_fn.

usb_hcd_flush_endpoint() has a retry loop that starts with a spin_lock_irq(),
but only gives up the spinlock, not the irq_disable before jumping to the
rescan label.
Split the spin_lock_irq into the retryable part and the local_irq_disable()
that is only done once as a micro-optimization and sligh
