2009-11-24drm/radeon/kms: Report vga connector is connected according to ddc_probeJerome Glisse
On broken EDID we were reporting vga connector to be disconnected even if ddc probe did found a monitor. This patch report that the connector is connected on such case. This allow drm to add a fail safe mode (800x600 at the time of this patch) thus user can boot and later add a mode which match its monitor capabilities.

2009-11-24drm: mm always protect change to unused_nodes with unused_lock spinlockJerome Glisse
unused_nodes modification needs to be protected by unused_lock spinlock. Here is an example of an usage where there is no such protection without this patch. Process 1: 1-drm_mm_pre_get(this function modify unused_nodes list) 2-spin_lock(spinlock protecting mm struct) 3-drm_mm_put_block(this function might modify unused_nodes list but doesn't protect modification with unused_lock) 4-spin_unlock(spinlock protecting mm struct) Process2: 1-drm_mm_pre_get(this function modify unused_nodes list) At this point Process1 & Process2 might both be doing modification to unused_nodes list. This patch add unused_lock protection into drm_mm_put_block to avoid such issue. Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-11-24drm/radeon/kms: Disable TV load detect on RS400,RC410,RS480Jerome Glisse
RS400,RC410,RS480 chipset seems to report a lot of false positive with load detect on TV output. We haven't yet found a way to make load detect reliable on those chipset, thus just disable it for TV output. Would avoid user to experience phantom screen because X believe there is a monitor connected to the TV output.

2009-11-24drm/radeon/kms: read back register before writing in IIO.Dave Airlie
This fixes RH bugzilla #527874. On resume the atom posting wasn't working, however vbe posting was going fine, after 2 weeks over irc, and 8 hrs with the hardware, I tracked it down to the memory device table and it access the MC registers via IIO, it appears the rv515 atom iio table might not be fully functional, so adding a readback before doing a write either provides enough delay to make things resume correctly.

2009-11-24drm/radeon/kms: resume AGP by calling init.Dave Airlie
AGP resume was broken since we moved to the new init path, because we never re-enabled AGP on these systems at resume time. This patch just calls the AGP resume call which just does the reinit at resume time like the old path did. Since AGP is pretty much gpu independant I did it outside the gpu specific code.

2009-11-23sparc64: Fix definition of VMEMMAP_SIZE.David S. Miller
This was the cause of various boot failures on V480, V880, etc. systems. Kernel image memory was being overwritten because the vmemmap[] array was being sized to small. So if you had physical memory addresses past a certain point, the early bootup would spam all over variables in the kernel data section. The vmemmap mappings map page structs, not page struct pointers. And that was the key thinko in the macro definition. This was fixable thanks to the help, reports, and tireless patience of Hermann Lauer. Reported-by: Hermann Lauer <Hermann.Lauer@iwr.uni-heidelberg.de> Signed-off-by: David S.

2009-11-24Silence the existing API for capability version compatibility check.Andrew G. Morgan
When libcap, or other libraries attempt to confirm/determine the supported capability version magic, they generally supply a NULL dataptr to capget(). In this case, while returning the supported/preferred magic (via a modified header content), the return code of this system call may be 0, -EINVAL, or -EFAULT. No libcap code depends on the previous -EINVAL etc. return code, and all of the above three return codes can accompany a valid (successful) attempt to determine the requested magic value. This patch cleans up the system call to return 0, if the call is successfully being used to determine the supported/preferred capability magic value. Signed-off-by: Andrew G.

2009-11-23pktgen: Fix device name comparesEric Dumazet
Commit e6fce5b916cd7f7f7 (pktgen: multiqueue etc.) tried to relax the pktgen restriction of one device per kernel thread, adding a '@' tag to device names. Problem is we dont perform check on full pktgen device name. This allows adding many time same 'device' to pktgen thread pgset "add_device eth0@0" one session later : pgset "add_device eth0@0" (This doesnt find previous device) This consumes ~1.5 MBytes of vmalloc memory per round and also triggers this warning : [ 673.186380] proc_dir_entry 'pktgen/eth0@0' already registered [ 673.186383] Modules linked in: pktgen ixgbe ehci_hcd psmouse mdio mousedev evdev [last unloaded: pktgen] [ 673.186406] Pid: 6219, comm: bash Tainted: G W 2.6.32-rc7-03302-g41cec6f-dirty #16 [ 673.186410] Call Trace: [ 673.186417] [<ffffffff8104a29b>] warn_slowpath_common+0x7b/0xc0 [ 673.186422] [<ffffffff8104a341>] warn_slowpath_fmt+0x41/0x50 [ 673.186426] [<ffffffff8114e789>] proc_register+0x109/0x210 [ 673.186433] [<ffffffff8100bf2e>] ? apic_timer_interrupt+0xe/0x20 [ 673.186438] [<ffffffff8114e905>] proc_create_data+0x75/0xd0 [ 673.186444] [<ffffffffa006ad38>] pktgen_thread_write+0x568/0x640 [pktgen] [ 673.186449] [<ffffffffa006a7d0>] ? pktgen_thread_write+0x0/0x640 [pktgen] [ 673.186453] [<ffffffff81149144>] proc_reg_write+0x84/0xc0 [ 673.186458] [<ffffffff810f5a58>] vfs_write+0xb8/0x180 [ 673.186463] [<ffffffff810f5c11>] sys_write+0x51/0x90 [ 673.186468] [<ffffffff8100b51b>] system_call_fastpath+0x16/0x1b [ 673.186470] ---[ end trace ccbb991b0a8d994d ]--- Solution to this problem is to use a odevname field (includes @ tag and suffix), instead of using netdevice name.

2009-11-22rcu: Fix grace-period-stall bug on large systems with CPU hotplugPaul E. McKenney
When the last CPU of a given leaf rcu_node structure goes offline, all of the tasks queued on that leaf rcu_node structure (due to having blocked in their current RCU read-side critical sections) are requeued onto the root rcu_node structure. This requeuing is carried out by rcu_preempt_offline_tasks(). However, it is possible that these queued tasks are the only thing preventing the leaf rcu_node structure from reporting a quiescent state up the rcu_node hierarchy. Unfortunately, the old code would fail to do this reporting, resulting in a grace-period stall given the following sequence of events: 1. Kernel built for more than 32 CPUs on 32-bit systems or for more than 64 CPUs on 64-bit systems, so that there is more than one rcu_node structure. (Or CONFIG_RCU_FANOUT is artificially set to a number smaller than CONFIG_NR_CPUS.) 2. The kernel is built with CONFIG_TREE_PREEMPT_RCU. 3. A task running on a CPU associated with a given leaf rcu_node structure blocks while in an RCU read-side critical section -and- that CPU has not yet passed through a quiescent state for the current RCU grace period. This will cause the task to be queued on the leaf rcu_node's blocked_tasks[] array, in particular, on the element of this array corresponding to the current grace period. 4. Each of the remaining CPUs corresponding to this same leaf rcu_node structure pass through a quiescent state. However, the task is still in its RCU read-side critical section, so these quiescent states cannot be reported further up the rcu_node hierarchy. Nevertheless, all bits in the leaf rcu_node structure's ->qsmask field are now zero. 5. Each of the remaining CPUs go offline. (The events in step #4 and #5 can happen in any order as long as each CPU passes through a quiescent state before going offline.) 6. When the last CPU goes offline, __rcu_offline_cpu() will invoke rcu_preempt_offline_tasks(), which will move the task to the root rcu_node structure, but without reporting a quiescent state up the rcu_node hierarchy (and this failure to report a quiescent state is the bug). But because this leaf rcu_node structure's ->qsmask field is already zero and its ->block_tasks[] entries are all empty, force_quiescent_state() will skip this rcu_node structure. Therefore, grace periods are now hung. This patch abstracts some code out of rcu_read_unlock_special(), calling the result task_quiet() by analogy with cpu_quiet(), and invokes task_quiet() from both rcu_read_lock_special() and __rcu_offline_cpu(). Invoking task_quiet() from __rcu_offline_cpu() reports the quiescent state up the rcu_node hierarchy, fixing the bug. This ends up requiring a separate lock_class_key per level of the rcu_node hierarchy, which this patch also provides. Signed-off-by: Paul E.

o Along with netdev->perm_addr, mac address will be maintained in device private structure. o Device limitation: We need to set mac address when ever interface comes up. In ALB/TAL mode, bonding driver calls set_mac for all slave with bond mac address. But bonding driver set netdev->dev_addr field to its original value, after enslaving interfaces. When ever active slave changes, it swap dev_addr of inactive slave with active. Yet it doesn't notify driver about change in netdev->dev_addr. As netxen driver need to set mac addr when ever interface comes up, it can't rely on netdev->dev_addr field. Specially in case of bonding mode ALB/TLB.

2009-11-20drivers/net: ks8851_mll ethernet network driver -resubmitDavid J. Choi
Summary of Changes: -Fix to receive multicast packets by setting the corresponding hardware bit during initialization. -Fix to re-enable the interface [by interface up command(ifup)] while the interface is down. -Fix to be able to down the interface by passing the last parameter correctly to request_irq(). -Remove to read 4 extra bytes from the receiving queue after reading a packet, even though it does not cause a predictable issue now. -Remove occurrences of transmission done interrupt in order to tx throughput enhancement. -Enable IP checksum for packet receiving by setting the corresponding hardware bit during initialization. -Relocate ks_enable_int()/ks_disable_int() in order not to declare those functions at the beginning of the file. -Rename ks_enable()/_disable() to ks_enable_qmu()/ks_disable_qmu() in order to give more meaningful names and relocate them not declaire those functions at the beginning of the file.

2009-11-20e1000e: do not initiate autonegotiation during OEM configurationBruce Allan
When configuring the OEM bits in the PHY on 82577/82578, do not restart autonegotiation if the firmware is blocking it (e.g. when an IDE-R session is active) because the link must not go down.
