Hello! These four patches provides a pair of new APIs and documentation to handle a couple of cases that David Howells came across when running an NFS workload under CONFIG_PROVE_RCU, along with some comment improvements suggested by David and also some by Yong Zhang.

[RFC] Try a bit harder to get output on the screen at panic time
This set of 3 patches makes it a little more likely we'll get panic output onto the screen even when X is running, assuming a KMS enabled stack anyway. It gets me from a blank or very sparsely populated black screen at panic time, to one including the full backtrace and panic output at panic time (tested with "e... 9 Apr 2010 18:59

[PATCH] drm: add locked variant of drm_fb_helper_force_kernel_mode
Needed for panic and kdb, since we need to avoid taking the mode_config mutex.

[PATCH] vt: try harder to print output when panicing
At panic time (i.e. when oops_in_progress is set) we should try a bit harder to update the screen and make sure output gets to the VT, since some drivers are capable of flipping back to it. So make sure we try to unblank and update the display if called from a panic context. Signed-off-by: Jesse Barnes <jbarne... 9 Apr 2010 18:59

[PATCH] fbcon: assume console is active if panicing
This allows us to draw to the fbcon buffer in a panic situation, in case the low level driver can flip to it at panic time.
