2009-10-07amd64_edac: fix DRAM base and limit address extractionBorislav Petkov
K8 DRAM base and limit addresses from F1x40 +8*i and F1x44 + 8*i, where i in (0..7) are both bits 39-24 and therefore the shifting should be done by 24 and not by 8. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2009-10-07amd64_edac: fix driver instance lookup table allocationBorislav Petkov

2009-10-07ALSA: hda - Fix yet another auto-mic bug in ALC268Takashi Iwai
Since patch_alc268() doesn't call set_capture_mixer() (due to its h/w design different from other siblings), it needs to call fixup_automic_adc() explicitly to set up the auto-mic routing. Otherwise the indices for int/ext mics aren't set properly. Reference: Novell bnc#544899 http://bugzilla.novell.com/show_bug.cgi?id=544899 Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-10-07Revert "Revert "ide: try to use PIO Mode 0 during probe if possible""Bartlomiej Zolnierkiewicz
This reverts commit 24df31acaff8465d797f0006437b45ad0f2a5cb1. The root cause of reported system hangs was (now fixed) sis5513 bug and not "ide: try to use PIO Mode 0 during probe if possible" change (commit 6029336426a2b43e4bc6f4a84be8789a047d139e) so the revert was incorrect (it simply replaced one regression with the other one).

2009-10-07sis5513: fix PIO setup for ATAPI devicesBartlomiej Zolnierkiewicz
Clear prefetch setting before potentially (re-)enabling it in config_drive_art_rwp() so the transition of the device type on the port from ATA to ATAPI (i.e. during warm-plug operation) is handled correctly. This is a really old bug (it probably goes back to very early days of the driver) but it was only affecting warm-plug operation until the recent "ide: try to use PIO Mode 0 during probe if possible" change (commit 6029336426a2b43e4bc6f4a84be8789a047d139e).

2009-10-07NOHZ: update idle state also when NOHZ is inactiveEero Nurkkala
Commit f2e21c9610991e95621a81407cdbab881226419b had unfortunate side effects with cpufreq governors on some systems. If the system did not switch into NOHZ mode ts->inidle is not set when tick_nohz_stop_sched_tick() is called from the idle routine. Therefor all subsequent calls from irq_exit() to tick_nohz_stop_sched_tick() fail to call tick_nohz_start_idle(). This results in bogus idle accounting information which is passed to cpufreq governors. Set the inidle flag unconditionally of the NOHZ active state to keep the idle time accounting correct in any case.

2009-10-07ethoc: use system memory as bufferThomas Chou
This patch enabled the ethoc to allocate system memory as buffer when there is no dedicated buffer memory. Some hardware designs may not have dedicated buffer memory such as on chip or off chip SRAM. In this case, only one memory resource is supplied in the platform data instead of two. Then a DMA buffer can be allocated from system memory and used for the transfer.

2009-10-07ethoc: align received packet to make IP header at word boundaryThomas Chou
The packet buffer is allocated at 4 bytes boundary, but the IP header length and version bits is located at byte 14. These bit fields access as 32 bits word and caused exception on processors that do not support unaligned access. The patch adds 2 bytes offset to make the bit fields word aligned.

2009-10-07ethoc: fix buffer address mappingThomas Chou

2009-10-07rcu: Place root rcu_node structure in separate lockdep classPaul E. McKenney
Before this patch, all of the rcu_node structures were in the same lockdep class, so that lockdep would complain when rcu_preempt_offline_tasks() acquired the root rcu_node structure's lock while holding one of the leaf rcu_nodes' locks. This patch changes rcu_init_one() to use a separate spin_lock_init() for the root rcu_node structure's lock than is used for that of all of the rest of the rcu_node structures, which puts the root rcu_node structure's lock in its own lockdep class.

2009-10-07rcu: Make hot-unplugged CPU relinquish its own RCU callbacksPaul E. McKenney
The current interaction between RCU and CPU hotplug requires that RCU block in CPU notifiers waiting for callbacks to drain. This can be greatly simplified by having each CPU relinquish its own callbacks, and for both _rcu_barrier() and CPU_DEAD notifiers to adopt all callbacks that were previously relinquished. This change also eliminates the possibility of certain types of hangs due to the previous practice of waiting for callbacks to be invoked from within CPU notifiers. If you don't every wait, you cannot hang. Signed-off-by: Paul E.

2009-10-07rcu: Move rcu_barrier() to rcutreePaul E. McKenney
Move the existing rcu_barrier() implementation to rcutree.c, consistent with the fact that the rcu_barrier() implementation is tied quite tightly to the RCU implementation.

2009-10-06libata: fix incorrect link online check during probeTejun Heo
While trying to work around spurious detection retries for non-existent devices on slave links, commit 816ab89782ac139a8b65147cca990822bb7e8675 incorrectly added link offline check logic before ata_eh_thaw() was called. This means that if an occupied link goes down briefly at the time that offline check was performed, device class will be cleared to ATA_DEV_NONE and libata wouldn't retry thus failing detection of the device. The offline check should be done after the port is thawed together with online check so that such link glitches can be detected by the interrupt handler and handled properly.
