Hi;
In menuconfig, General setup -> Irq subsystem contains two
possible menu-items. Sometimes, neither menu-item exists. This
patch prevents the Irq susystem menu from appearing at all unless it
will contain at least one menu-item, preventing a confusing, empty menu.

Use uninterruptible mutex_lock in the release() file op to make sure all
resources are properly freed when a process is being terminated. Returning
-ERESTARTSYS has no effect for a terminating process and this may cause driver
resources not to be released.
This was found using the following semant
This is the same kind of bug as the one fixed by
ddc43d6dc7df0849fe41b91460fa76145cf87b67 : mutex_lock() must be used in the
device_release file operation in order for all resources to be freed, since
returning -RESTARTSYS has no effect here.

Yes until the next check_new_page() whenever that is. If the migration
works it will be earlier, otherwise later.

As Fengguang said -- memory error handling is tricky. Lots of things
could be done in theory, but they all have a cost in testing and
maintenance.
In general they are only worth doing if the situation is

[What we are doing]
This patchset provide a boot option for user to specify ZONE_MOVABLE memory
map for each node in the system.
movablecore_map=nn[KMG]@ss[KMG]
This option make sure memory range from ss to ss+nn is movable memory.
[Why we do this]
If we hot remove a memroy, the memory cannot h
This patch adds functions to parse movablecore_map boot option. Since the
option could be specified more then once, all the maps will be stored in
the global variable movablecore_map.map array.
And also, we keep the array in monotonic increasing order by start_pfn.
And merge all overlapped ranges.
If kernelcore or movablecore is specified at the same time
with movablecore_map, movablecore_map will have higher
priority to be satisfied.
This patch will make find_zone_movable_pfns_for_nodes()
calculate zone_movable_pfn[] with the limit from
zone_movable_limit[].

From: Yasuaki Ishimatsu
If system can create movable node which all memory of the
node is allocated as ZONE_MOVABLE, setup_node_data() cannot
allocate memory for the node's pg_data_t.
So, use memblock_alloc_try_nid() instead of memblock_alloc_nid()
to retry when the first allocation fails.
Signe
This still is [RFC v3] because just passed my simple test
with TCMalloc tweaking.
I hope more inputs from user-space allocator people and test patch
with their allocator because it might need design change of arena
management design for getting real vaule.

No, soft offlining can still allow accesses for some time. It'll never kill
anything.
Hard tries much harder and will kill.
