2007-07-17Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki35-37/+42
Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

2007-07-17Slab allocators: Replace explicit zeroing with __GFP_ZEROChristoph Lameter1-2/+2
kmalloc_node() and kmem_cache_alloc_node() were not available in a zeroing variant in the past. But with __GFP_ZERO it is possible now to do zeroing while allocating. Use __GFP_ZERO to remove the explicit clearing of memory via memset whereever we can.

2007-07-16eHEA: Introducing support vor DLPAR memory addThomas Klein5-65/+275
This patch adds support for DLPAR memory add to the eHEA driver. To detect whether memory was added the driver uses its own memory mapping table and checks for kernel addresses whether they're located in already known memory sections. If not the function ehea_rereg_mrs() is triggered which performs a rebuild of the mapping table and a re-registration of the global memory region.

In drivers/pnp/isapnp/core.c::isapnp_read_tag() there is a test of 'type' being == 0 a bit down in the function. That test doesn't make any sense. If 'type' could indeed be NULL, then the test happens way too late as we'd already have tried to dereference the pointer earlier and looking at the callers it also turns out that there is no way type can ever actually be NULL. So the test is completely pointless and should just be removed.
