* hpt366: rework rate filteringSergei Shtylyov2007-02-07
| | | | | | | | | | | | | | | | | | | | | | | - Rework hpt3xx_ratemask() and hpt3xx_ratefilter() so that the former returns the max. mode computed at the load time and doesn't have to do bad Ultra33 drive list lookups anymore; remove the duplicate code from the latter function. Move the quirky drive list lookup into hpt3xx_quirkproc() where it should have been from the start... - Disable UltraATA/100 for HPT370 by default as the 33 MHz ATA clock being used does not allow for it, and this *greatly* increases the transfer speed. - Save some space by using byte-wide fields in struct hpt_info; switch to reading the 8-bit PCI revision ID reg. only, not the whole 32-bit reg. - Start incrementing the driver version number with each patch (should have been done from the first one posted).

| * [IA64] register memory ranges in a consistent mannerBob Picco2007-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While pursuing and unrelated issue with 64Mb granules I noticed a problem related to inconsistent use of add_active_range. There doesn't appear any reason to me why FLATMEM versus DISCONTIG_MEM should register memory to add_active_range with different code. So I've changed the code into a common implementation. The other subtle issue fixed by this patch was calling add_active_range in count_node_pages before granule aligning is performed. We were lucky with 16MB granules but not so with 64MB granules. count_node_pages has reserved regions filtered out and as a consequence linked kernel text and data aren't covered by calls to count_node_pages. So linked kernel regions wasn't reported to add_active_regions. This resulted in free_initmem causing numerous bad_page reports. This won't occur with this patch because now all known memory regions are reported by register_active_ranges.

| * [IA64] Clear IRQ affinity when unregisteredAlex Williamson2007-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we offline a CPU, migrate_irqs() tries to determine whether the affinity bits of the IRQ descriptor match any of the remaining online CPUs. If not, it fixes up the interrupt to point somewhere else. Unfortunately, if an IRQ is unregistered the IRQ descriptor may still have affinity to the CPU being offlined, but the no_irq_chip handler doesn't provide a set_affinity function. This causes us to hit the WARN_ON in migrate_irqs(). The easiest solution seems to be setting all the bits in the affinity mask when the last interrupt is removed from the vector. I hit this on an older kernel with Xen/ia64 using driver domains (so it probably needs more testing on upstream). Xen essentially uses the bind/unbind interface in sysfs to unregister a device from a driver and thus unregister the interrupt.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a NULL-pointer dereference in ia64_machine_kexec(). The variable ia64_kimage is set in machine_kexec_prepare() which is called from sys_kexec_load(). If kdump wasn't configured before, ia64_kimage is NULL. machine_kdump_on_init() passes ia64_kimage() to machine_kexec() which assumes a valid value. The patch also adds a few sanity checks for the image to simplify debugging of similar problems in future.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | I encountered one problem when running ptrace test case the situation is this: traced process's syscall parameter needs to be accessed, but for sys_clone system call with clone_flag (CLONE_VFORK | CLONE_VM | SIGCHLD) parameter. This syscall's parameter accessing result is wrong. The reason is that vforked child process mm point is the same, but tgid is different. Without this patch find_thread_for_addr will return vforked process if vforked process is also stopped, but not the thread which calls vfork syscall. Signed-off-by: Tony Luck <tony.luck@intel.com>
| * [IA64] use snprintf() on features field of /proc/cpuinfoAron Griffis2007-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some patches have turned up on xen-devel recently to convert strcpy() to safer alternatives and so forth. While reviewing those patches I noticed that the features string building could be cleaned up. This patch uses snprintf() instead of strcpy() and direct character pointer manipulation. It makes the features string building safe and gets rid of the special case for features output in show_cpuinfo() Additionally I removed the (int) cast of ARRAY_SIZE, which seems to serve no purpose.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As is pointed out in http://www.gelato.org/community/view_linear.php?id=1_1036&from=authors&value=Ian%20Wienand#1_1039, if single step on break instruction, the break fault has higher priority than the single-step trap. When the break fault handler is entered, it advances the IP by 1 instruction so break instruction single-stepping is skipped, actually it is next instruction which is single stepped. This patch modifies this, it adds TIF_SINGLESTEP bit for thread flags, and generate a fake sigtrap when single stepping break instruction. Test case in attachment can verify this.

Add this quirk and HID_QUIRK_MULTI_INPUT to 0810:0001. PantherLord Twin USB Joystick, 0810:0001 has separate input reports for 2 distinct game controllers in the same interface, so it needs HID_QUIRK_MULTI_INPUT. However, the device also contains one output report per controller which is used to control the force feedback function, and we do not want those to appear as separate input devices as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The iWARP connection manager uses the ib_addr services to do route resolution (neighbour discovery in the IP world). The ib_addr netevent callback routine, however, currently only acts on InfiniBand neighbour updates. It needs to act on ethernet neighbour updates as well. This patch just removes filtering on device type altogether and will trigger on any neighour updates where the nud_type is valid. This simplifies the code some.

| * | | IB: Make sure struct ib_user_mad.data is alignedJason Gunthorpe2007-02-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make the untyped data region in ib_user_mad have type u64 so that it gets aligned properly. This avoids alignment faults in ib_umad when casting the data field to an rmpp_mad and accessing the 64-bit tid field on architectures like ia64.

| * | | IB/srp: Don't wait for response when QP is in error state.Ishai Rabinovitz2007-02-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When there is a call to send_tsk_mgmt SRP posts a send and waits for 5 seconds to get a response. When the QP is in the error state it is obvious that there will be no response so it is quite useless to wait. In fact, the timeout causes SRP to wait a long time to reconnect when a QP error occurs. (Each abort and each reset_device calls send_tsk_mgmt, which waits for the timeout). The following patch solves this problem by identifying the failure and returning an immediate error code.

| * | | IB: Return qp pointer as part of ib_wcMichael S. Tsirkin2007-02-04

The following patch replaces this with the pointer to qp itself, and updates all low level drivers and all users. This has the following advantages: - Ability to get a per-qp context through wc->qp->qp_context - Existing drivers already have the qp pointer ready in poll cq, so this change actually saves a tiny bit (extra memory read) on data path (for ehca it would actually be expensive to find the QP pointer when polling a CQ, but ehca does not support SRQ so we can leave wc->qp as NULL for ehca) - Users that need the QP number can still get it through wc->qp->qp_num Use case: In IPoIB connected mode code, I have a common CQ shared by multiple QPs. To track connection usage, I need a way to get at some per-QP context upon the completion, and I would like to avoid allocating context object per work request just to stick a QP pointer into it. With this code, I can just use wc->qp->qp_context. Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
