out_of_memory() may be called when an allocation is failing and the direct reclaim is not making any progress. This does not take into account the requested order of the allocation. If the request if for an order larger than PAGE_ALLOC_COSTLY_ORDER, it is reasonable to fail the allocation because the kernel makes no guarantees about those allocations succeeding. This false OOM situation can occur if a user is trying to grow the hugepage pool in a script like; #!/bin/bash REQUIRED=$1 echo 1 > /proc/sys/vm/hugepages_treat_as_movable echo $REQUIRED > /proc/sys/vm/nr_hugepages ACTUAL=`cat /proc/sys/vm/nr_hugepages` while [ $REQUIRED -ne $ACTUAL ]; do echo Huge page pool at $ACTUAL growing to $REQUIRED echo $REQUIRED > /proc/sys/vm/nr_hugepages ACTUAL=`cat /proc/sys/vm/nr_hugepages` sleep 1 done This is a reasonable scenario when ZONE_MOVABLE is in use but triggers OOM easily on 2.6.23-rc1. This patch will fail an allocation for an order above PAGE_ALLOC_COSTLY_ORDER instead of killing processes and retrying. Signed-off-by:

Leaving kobject_actions[] in kobject_uevent.c, but putting it outside the #ifdef looks indeed like the best solution to me. This way, we avoid adding #ifdef CONFIG_HOTPLUG into core.c, when all other functions called do not need such a thing. Signed-off-by:

Remove some more dead code from the pxa2xx_udc driver: support for a no-longer-undocumented hardware "test mode". Newer chips made this the default, evidently as the best workaround for deep silicon bugs. The interest was that this seemed to be the only way to kick in the (documented!) double buffering capability. Signed-off-by:

Update the scatterlist logic so that PIO options are also disabled when an IOMMU may have coalesced pages during dma_map_sg() ... it's not just HIGHMEM that can make trouble supporting both PIO and DMA based host controller drivers. There also seems to be a cross-arch issue here, with 64bit powerpc not using an IOMMU define ... and its IOMMU_VMERGE config can always be overridden on the kernel command line. So this is better, but still imperfect. Signed-off-by:
