list_for_each_entry binds its first argument to a non-null value, and thus any null test on the value of that argument is superfluous. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ iterator I; expression x,E,E1,E2; statement S,S1,S2; @@ I(x,...) { <... - if (x != NULL || ...)

for_each_node_by_name only exits when its first argument is NULL, and a subsequent call to of_node_put on that argument is unnecessary.

During kdump we run the crash handlers first then stop all other CPUs. We really want to stop all CPUs as close to the fail as possible and also have a very controlled environment for running the crash handlers, so it makes sense to reverse the order.

Some modules (like eHCA) want to map all of kernel memory, for this to work with a relocated kernel, we need to export kernstart_addr so modules can use PHYSICAL_START and memstart_addr so they could use MEMORY_START. Note that the 32bit code already exports these symbols. Signed-off-By: Sonny Rao <sonnyrao@us.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

This makes the 64-bit kernel use 64-bit signed integers for the counter (effectively supporting 32-bit of active count in the semaphore), thus avoiding things like overflow of the mmap_sem if you use a really crazy number of threads Note: Ideally the type in the structure should be atomic_long_t rather than "long". However, there's some nasty issues with that. It needs to be initialized statically -and- lib/rwsem.c does things like sem->count = RWSEM_UNLOCKED_VALUE; Now, if you mix in the fact that atomic_* types are actually structures with one member and note typedefs of a scalar, it makes its really nasty. So I stuck to what we did before using a long and casts for now. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

commit f3c5c1bf (netfilter: xtables: make ip_tables reentrant) forgot to also compute the jumpstack size in the compat handlers. Result is that "iptables -I INPUT -j userchain" turns into -j DROP. Reported by Sebastian Roesner on #netfilter, closes http://bugzilla.netfilter.org/show_bug.cgi?id=669. Note: arptables change is compile-tested only.

Don't ask how ACPI_TOSHIBA got enabled on in desktop system's .config - I don't know. But it has silently been there until I tried 2.6.36-rc2, where it broke the build because I don't have LED support turned on. Attached patch fixes things up. (I had to change BACKLIGHT_CLASS_DEVICE to "depends" because otherwise I get unsightly core dumps out of scripts/kconfig/conf). jon -- toshiba: make sure we pull in LED support The Toshiba extras driver uses the LED module, so make sure we have it configure in.

by defining in terms of (1<<N). XEN_UNPLUG_UNNECESSARY and XEN_UNPLUG_NEVER are only used within the kernel and are not defined as a bit on the unplug IO port.

It is not immediately clear what this option causes to become ignored. The actual meaning is that it is not necessary to unplug the emulated devices to safely use the PV ones, even if the platform does not support the unplug protocol. (pressumably the user will only add this option if they have ensured that their domain configuration is safe). I think xen_emul_unplug=unnecessary better captures this.
