Although we use u64 to pass userspace pointers to the kernel to avoid compat_ioctl, it doesn't work in some ppc platform. So wrap them with compat_ptr and add compat_ioctl. The detailed discussion about compat_ptr can be found in thread http://lkml.org/lkml/2009/10/27/423. We indeed met with a bug when testing on ppc(-EFAULT is returned when using old_path). This patch try to fix this. I have tested in ppc64(with 32 bit reflink) and x86_64(with i686 reflink), both works. Signed-off-by:

Mainline commit aad1b153 made the dlm_begin_reco_handler() return -EAGAIN instead of EAGAIN. As this error is transmitted over the wire, we want the receiver, dlm_send_begin_reco_message(), to understand both the older EAGAIN and the newer -EAGAIN, to allow rolling upgrade of the cluster nodes.

In CoW, we have to make sure that the page is already written out to the disk. So we have a BUG_ON(PageDirty(page)). In ppc platform we have pagesize=64K, so if the cs=4K, if the file have fragmented clusters, we will map the page many times. See this file as an example. Tree Depth: 0 Count: 19 Next Free Rec: 14 ## Offset Clusters Block# Flags 0 0 4 2164864 0x2 Refcounted 1 4 2 9302792 0x2 Refcounted ... We have to replace the extent recs one by one, so the page with index 0 will be mapped and dirtied twice. I'd like to leave the BUG_ON there while adding a check so that in case we meet with an error in other platforms, we can find it easily. Signed-off-by:

In ocfs2_duplicate_clusters_by_page, we calculate map_end by shifting page_index. But actually in case we meet with a large offset(say in a i686 box, poff_t is only 32 bits and page_index=2056240), we will overflow. So change the type of page_index to loff_t. Signed-off-by:

When a lock resource is migrated, the dlm compares the migrated locks with that that was already existing on the new node. If the comparison fails, it BUGs. This patch prints more messages when the comparison fails inorder to help with the root cause analyis. http://oss.oracle.com/bugzilla/show_bug.cgi?id=1206 This does not fix bz1206. However, if we run into it again, we will have more information to chew on. Signed-off-by:

During lock resource migration, o2dlm fills the packet with a LVB from the first valid lock. For sanity, it ensures that the other valid locks have the same LVB. If not, it BUGs. The valid locks are ones that have granted EX or PR lock levels and are either on the Granted or Converting lists. Locks in the Blocked list cannot have a valid LVB. This patch ensures that we skip the locks in the Blocked list. Fixes oss bugzilla#1202 http://oss.oracle.com/bugzilla/show_bug.cgi?id=1202Signed-off-by:

If ->follow_link handler returns an error, it should decrement nd->path refcnt. But ocfs2_fast_follow_link() doesn't decrement. This patch fixes the problem by using nd_set_link() style error handling instead of playing with nd->path. Signed-off-by:

The list macros use LIST_POISON1 and LIST_POISON2 as undereferencable pointers in order to trap erronous use of freed list_heads. Unfortunately userspace can arrange for those pointers to actually be dereferencable, potentially turning an oops to an expolit. To avoid this allow architectures (currently x86_64 only) to override the default values for these pointers with truly-undereferencable values. This is easy on x86_64 as the virtual address space is large and contains areas that cannot be mapped. Other 64-bit architectures will likely find similar unmapped ranges. [ingo: switch to 0xdead000000000000 as the unmapped area] [ingo: add comments, cleanup] [jaswinder: eliminate sparse warnings] Acked-by:

David Howells authored
Access to the ASB2305's PCnet32 NIC doesn't work correctly because when the NIC attempts to update the ring buffer flags by DMA, the change to RAM crops up about 17uS after the interrupt line is asserted. This is almost certainly due to a bug in the PCI bridge FPGA on that board. We can get around this by making dma_alloc_coherent() put the ring buffer in the SRAM attached to the PCI bridge rather than in the SDRAM. Signed-off-by:

Insert PCI root bus resources for the MN10300-based ASB2305 development kit motherboard. This is required because the CPU's window onto the PCI bus address space is considerably smaller than the CPU's full address space and non-PCI devices lie outside of the PCI window that we might want to access. Without this patch, the PCI root bus uses the platform-level bus resources, and these are then confined to the PCI window, thus making platform_device_add() reject devices outside of this window. We also add a reservation for the PCI SRAM region. Signed-off-by:

Use the generic pci_enable_resources() instead of the arch-specific code. Unlike this arch-specific code, the generic version: - checks PCI_NUM_RESOURCES (11), not 6, resources - skips resources that have neither IORESOURCE_IO nor IORESOURCE_MEM set - skips ROM resources unless IORESOURCE_ROM_ENABLE is set - checks for resource collisions with "!r->parent" Signed-off-by:

gcc 4.2.1 for MN10300 is more agressive than the older gcc in reordering/moving other insns between an insn that sets flags and an insn that uses those flags. This leads to trouble with asm statements which are missing an explicit "cc" clobber. This patch adds the explicit "cc" clobber to asm statements which do indeed clobber the condition flags.

Mark Salter authored
This fixes a signal stack handling problem in the MN10300 arch. When new threads are cloned with CLONE_VM, they don't inherit the alternate signal stack. They do share the signal flags, though. When deciding whether to use an alternate stack, the arch code needs to check to make sure the task struct contains a valid alternate stack. This patch fixes the MN10300 arch by using the sas_ss_flags() test provided by sched.h rather than the on_sig_stack() test which is insufficient by itself. Signed-off-by:

A long time ago we regarded zero page as file_rss and vm_normal_page doesn't return NULL. But now, we reinstated ZERO_PAGE and vm_normal_page's implementation can return NULL in case of zero page. Also we don't count it with file_rss any more. Then, RSS and PSS can't be matched. For consistency, Let's ignore zero page in smaps_pte_range. Signed-off-by:
