There are some machines around (large xSeries or Unisys ES7000) that
need physical IO-APIC destination mode to access all of their IO
devices. This currently doesn't work in UP kernels as used in
distribution installers.
This patch allows to compile even UP kernels as GENERICARCH which
allows to use physical or clustered APIC mode.

The v4l2 API documentation for VIDIOC_ENUMSTD says:
To enumerate all standards applications shall begin at index
zero, incrementing by one until the driver returns EINVAL.
The actual code, however, tests the index this way:
if (index<=0 || index >= vfd->tvnormsize) {
ret=-EINVAL;
So any application which passes in index=0 gets EINVAL right off the bat
- and, in fact, this is what happens to mplayer. So I think the
following patch is called for, and maybe even appropriate for a 2.6.18.x
stable release.

Invoking load_module() before param_sysfs_init() is called crashes in
mod_sysfs_setup(), since the kset in module_subsys is not initialized yet.
In my case, net-pf-1 is getting modprobed as a result of hotplug trying to
create a UNIX socket. Calls to hotplug begin after the topology_init
initcall.
Another patch for the same symptom (module_subsys-initialize-earlier.patch)
moves param_sysfs_init() to the subsys initcalls, but this is still not
early enough in the boot process in some cases. In particular,
topology_init() causes /sbin/hotplug to run, which requests net-pf-1 (the
UNIX socket protocol) which can be compiled as a module. Moving
param_sysfs_init() to the postcore initcalls fixes this particular race,
but there might well be other cases where a usermodehelper causes a module
to load earlier still.
The patch makes load_module() return an error rather than crashing the
kernel if invoked before module_subsys is initialized.

Assume that a cpu is *physically* offlined at boot time...
Because smpboot.c::smp_boot_cpu_map() canoot find cpu's sapicid,
numa.c::build_cpu_to_node_map() cannot build cpu<->node map for
offlined cpu.
For such cpus, cpu_to_node map should be fixed at cpu-hot-add.
This mapping should be done before cpu onlining.
This patch also handles cpu hotremove case.

Problem description:
We have additional_cpus= option for allocating possible_cpus. But nid
for possible cpus are not fixed at boot time. cpus which is offlined at
boot or cpus which is not on SRAT is not tied to its node. This will
cause panic at cpu onlining.
Usually, pxm_to_nid() mapping is fixed at boot time by SRAT.
But, unfortunately, some system (my system!) do not include
full SRAT table for possible cpus. (Then, I use
additiona_cpus= option.)
For such possible cpus, pxm<->nid should be fixed at
hot-add. We now have acpi_map_pxm_to_node() which is also
used at boot. It's suitable here.

If the timeout of an autofs mount is set to zero then umounts are disabled.
This works fine, however the kernel module checks the expire timeout and
goes no further if it is zero. This is not the right thing to do at
shutdown as the module is passed an option to expire mounts regardless of
their timeout setting.
This patch allows autofs to honor the force expire option.
