What is new in patch set v2
* patch 4 which was previously radeon specific was replaced with a
generic patch to save and restore the LUT data for all drivers
* minor white space cleanup vs checkpatch.pl in patches
The goal of this patch set is to add atomic kernel mode setting hooks
for the radeon and nouveau cards for the purpose of using kdb (the
kernel debug shell).
David Airlie had asked for more research into the gamma data
corruption after initially reviewing the patch that attempts to solve
the visible palette corruption after an atomic mode set operation.
The final conclusion was that other types of pallet corruption are
possible with the gamma data when using atomic mode setting so the
problem should be solved generically.
The mode_set_base_atomic() now receives and additional parameter to
note of the atomic mode set operation is an enter or exit such that a
driver can appropriately enable or disable hardware that will not work
in the polling context.
These patches have now passed the kgdb/kdb regression tests and are
deemed stable and ready for further integration and comment with the
hope of integrating the patches upstream.
Many thanks to Chris Ball for the contribution of the radeon and
nouveau hooks, as well as the time he spent helping debug the initial
LUT save and restore.
