Here's a patch to fix this -- compile tested only, since I have no idea what the hardware even is. Fix the build of the RME32 and RME96 drivers by having them use the PCI_DEVICE_ID_RME_xxx names defined in instead of the PCI_DEVICE_ID_xxx names that they used to define themselves. Also fix the typo in the id PCI_DEVICE_IDRME__DIGI96_8_PAD_OR_PST so the name is PCI_DEVICE_ID_RME_DIGI96_8_PAD_OR_PST.

For such expectations we lookup with cport=0 on incoming packet but it matches the format of the persistence templates causing packets to other persistent virtual servers to be forwarded to real server without creating connection. Later the reply packets are treated as foreign and not SNAT-ed. This patch changes the connection lookup for packets from clients: * introduce IP_VS_CONN_F_TEMPLATE connection flag to mark the connection as template * create new connection lookup function just for templates - ip_vs_ct_in_get * make sure ip_vs_conn_in_get hits only connections with IP_VS_CONN_F_NO_CPORT flag set when s_port is 0.

We can then use these accessors in ixp2000 code to access on-chip peripherals, instead of directly dereferencing pointers. This is for use by the ixp2000 microengine driver which was recently announced on netdev. We can't use readl/writel on the ixp2000 since it is usually run in big-endian mode, and on big-endian platforms, readl/writel perform byteswapping. A future patch will remove the readback from ixp2000_reg_write, since it's not needed to prevent erratum #66, and add manual readbacks to the places that need them (writes are not synchronous since we map in device space using XCB=101 nowadays), such as interrupt disabling and GPIO manipulation. See also: http://lists.arm.linux.org.uk/pipermail/linux-arm-kernel/2005-February/027084.html Patch has been ACKed by Jeff Garzik.

Thomas Gleixner reported that mmaping and unmapping each physical page in turn eventually caused the kernel to oops. It appears that pfn_valid() in the discontigmem case was too simplistic for proper operation. Tighten the logic so we also check if the PFN is within the range of the selected memory node.

Following FC-FS/FC-GS-x defintions of port speeds would look like: 1 GBit: 0x0001 2 GBit: 0x0002 4 GBit: 0x0004 10GBit: 0x0008 (and new in FC-LS: 8 Gbit: 0x0010 16GBit: 0x0020) I really appreciate if scsi_transport_fc.h would define port speeds according to FC-GS-x/FC-FS. Thus mapping of port speed capabilities to values defined in scsi_transport_fc.h can be avoided in the LLDD. Attached is a patch to change the definitions.

The advantage to this is that a break point can be placed on showreqs, so that upon showing the stack, you jump immediately into the debugger. While sysrq-t does the same thing, sysrq-t shows *all* threads stacks. It also doesn't work right now. In the future, I thought it might be acceptable to make this show all pids stacks, but perhaps leaving well enough alone and just using sysrq-t would be okay. For now, upon receiving the stack command, UML switches context to that thread, dumps its registers, and then switches context back to the original thread. Since UML compacts all threads into one of 4 host threads, this sort of mechanism could be expanded in the future to include other debugging helpers that sysrq does not cover. Note by jdike - The main benefit to this is that it brings an arbitrary thread back into context, where it can be examined by gdb. The fact that it dumps it stack is secondary. This provides the capability to examine a sleeping thread, which has existed in tt mode, but not in skas mode until now. Also, the other threads, that sysrq doesn't cover, can be gdb-ed directly anyway.

There is a micro-fixup is needed for the included file, which won't affect i386 behaviour at all.

However, it includes an unused var (taken from the "real" version) which GCC warns about. Remove it from all arches having that file version (i.e. same GIT id). $ git-diff-tree -r HEAD and $ git-ls-tree -r HEAD include/|grep 9feff4ce1424bc390608326240be369eb13aa648 may be more interesting than looking at the patch itself, to make sure I've just copied the arm header to all other archs having the original dummy version of this file.
