I fixed a bug in cgroup_clone() in Linus' tree in commit 7b574b7b ("cgroups: fix a race between cgroup_clone and umount") without noticing there was a cleanup patch in -mm tree that should be rebased (now commit 104cbd5, "cgroups: use task_lock() for access tsk->cgroups safe in cgroup_clone()"), thus resulted in lock inconsistency.

The commit "alpha: teach the compiler that BUG doesn't return" (ed6b9b97) moved the asm code into inline function which takes __FILE__ and __LINE__ as arguments. This violates asm constrains there ("i" - an immediate operand with constant value), so that compile may result in warning or error, depending on compiler version. Just adding an infinite loop to the BUG() is sufficient. Signed-off-by:

The lifetime of struct cgroup and struct mem_cgroup is different and mem_cgroup has its own reference count for handling references from swap_cgroup. This causes strange problem that the parent mem_cgroup dies while child mem_cgroup alive, and this problem causes a bug in case of use_hierarchy==1 because res_counter_uncharge climbs up the tree. This patch is for avoiding it by getting the parent at create, and putting it at freeing. Signed-off-by:

As of commit ba470de4 ("map: handle mlocked pages during map, remap, unmap") we now use the 'vma' variable at the end of mmap_region() to handle the page-in of newly mapped mlocked pages. However, if we merged adjacent vma's together, the vma we're using may be stale. We historically consciously avoided using it after the merge operation, but that got overlooked when redoing the locked page handling. This commit simplifies mmap_region() by doing any vma merges early, avoiding the issue entirely, and 'vma' will always be valid. As pointed out by Hugh Dickins, this depends on any drivers that change the page offset of flags to have set one of the VM_SPECIAL bits (so that they cannot trigger the early merge logic), but that's true in general.

_PAGE_COHERENT is now always set in _PAGE_RAM resp. PAGE_KERNEL. Thus it has to be masked out, if the BAT mapping should be non cacheable or CPU_FTR_NEED_COHERENT is not set. This will work on normal SMP setups because we force-set CPU_FTR_NEED_COHERENT as part of CPU_FTR_COMMON on SMP. Signed-off-by:

In the VIO bus code the wrappers for dma alloc_coherent and free_coherent calls are rounding to IOMMU_PAGE_SIZE. Taking a look at the underlying calls, the actual mapping is promoted to PAGE_SIZE. Changing the rounding in these two functions fixes under-reporting the entitlement used by the system. Without this change, the system could run out of entitlement before it believes it has and incur mapping failures at the firmware level. Also in the VIO bus code, the wrapper for dma map_sg is not exiting in an error path where it should. Rather than fall through to code for the success case, this patch adds the return that is needed in the error path. Signed-off-by:

This patch adds support for the FHCI USB controller, as found in the Freescale MPC836x and MPC832x processors. It can support Full or Low speed modes. Quite a lot the hardware is doing by itself (SOF generation, CRC generation and checking), though scheduling and retransmission is on software's shoulders. This controller does not integrate the root hub, so this driver also fakes one-port hub. External hub is required to support more than one device. Signed-off-by:
