Allow non-ARM SMP processors to use the SMP_ON_UP feature. CPUs supporting SMP must have the new CPU ID format, so check for this first. Then check for ARM11MPCore, which fails the MPIDR check.

Xfstests 224 will just sit there and spin for ever until eventually we give up flushing delalloc and exit. On my box this took several hours. I could not interrupt this process either, even though we use INTERRUPTIBLE. So do 2 things 1) Keep us from looping over and over again without reclaiming anything 2) If we get interrupted exit the loop I tested this and the test now exits in a reasonable amount of time, and can be interrupted with ctrl+c.

2011-01-31net: Add default_mtu() methods to blackhole dst_opsRoland Dreier
When an IPSEC SA is still being set up, __xfrm_lookup() will return -EREMOTE and so ip_route_output_flow() will return a blackhole route. This can happen in a sndmsg call, and after d33e455337ea ("net: Abstract default MTU metric calculation behind an accessor.") this leads to a crash in ip_append_data() because the blackhole dst_ops have no default_mtu() method and so dst_mtu() calls a NULL pointer. Fix this by adding default_mtu() methods (that simply return 0, matching the old behavior) to the blackhole dst_ops. The IPv4 part of this patch fixes a crash that I saw when using an IPSEC VPN; the IPv6 part is untested because I don't have an IPv6 VPN, but it looks to be needed as well.

2011-01-31[media] rc/streamzap: fix reporting response timesJarod Wilson
The streamzap driver has relatively low sampling resolution, and any delays in reporting events seem to cause some minor problems for the likes of irw when using the lirc bridge driver, resulting in a single keypress registering as multiple independent ones, rather than as a single press with repeats. If we call ir_raw_event_handle() more frequently and reset the rawir kfifo at end-of-signal, the behavior improves quite a bit.

This stabilizes what is received from both the HD-PVR and HVR-1950, even with their polling intervals at the default of 100, thus the removal of the custom 260ms polling_interval in pvrusb2-i2c-core.c.

2011-01-31drm/i915: Suppress spurious vblank interruptsChris Wilson
Hugh Dickins found that characters in xterm were going missing and oft delayed. Being the curious type, he managed to associate this with the new high-precision vblank patches; disabling these he found, restored the orderliness of his characters. The oddness begins when one realised that Hugh was not using vblanks at all on his system (fvwm and some xterms). Instead, all he had to go on were warning of a pipe underrun, curiously enough at around 60Hz. He poked and found that in addition to the underrun warning, the hardware was flagging the start of a new frame, a vblank, which in turn was kicking off the pending vblank processing code. There is little we can do for the underruns on Hugh's machine, a Crestline [965GM], which must have its FIFO watermarks set to 8. However, we do not need to process the vblank if we know that they are disabled... Reported-by: Hugh Dickins <hughd@google.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2011-01-31drm: Simplify and defend later checks when disabling a crtcChris Wilson
By setting the FB of a CRTC to NULL, we are turning off the CRTC (and so disable the unused encoders and connectors). As such we can simplify the later tests by making sure the set->mode is NULL. Setting the num_connectors to zero means that we do not need to loop over the unused connectors. All current usage appears correct, this only builds additional defense into the routine.

2011-01-31drm: Don't switch fb when disabling an outputChris Wilson
In drm_crtc_helper_set_config, we call drm_crtc_helper_set_mode which may return early and do no operation if the crtc is to be disabled. In this case we merrily swap to the new fb, discarding the old_fb believing that it has been cleaned up. However, due to the early return, the old_fb was not presented to the backend for correct reaping, and nor was the new one - which is about to be reaped via the drm_helper_disable_unused_functions(), leading to incorrect refcounting of the pinned objects.

2011-01-31watchdog: Fix broken nowatchdog logicMarcin Slusarz
Passing nowatchdog to kernel disables 2 things: creation of watchdog threads AND initialization of percpu watchdog_hrtimer. As hrtimers are initialized only at boot it's not possible to enable watchdog later - for me all watchdog threads started to eat 100% of CPU time, but they could just crash. Additionally, even if these threads would start properly, watchdog_disable_all_cpus was guarded by no_watchdog check, so you couldn't disable watchdog. To fix this, remove no_watchdog variable and use already existing watchdog_enabled variable.

Check if the device is already removed from alias handling and skip these steps to prevent the kernel panic.
