2008-09-26[ARM] pxa/idp: remove the unnecessary idp_init_irq()Eric Miao
TOUCH_PANEL_IRQ is never referenced, and set_irq_type() shouldn't be called in this way, remove it, as well as the idp_init_irq(), and use pxa25x_init_irq() instead.

2008-09-26[ARM] pxa: better MFP low power state support for pxa25x/pxa27xEric Miao
When configured as a specific low power state: MFP_LPM_DRIVE_LOW, MFP_LPM_DRIVE_HIGH, the corresponding GPDR register bit during low power mode shall be re-configured as output (if they are not configured so), thus the PGSRx bits can output. Create an additional low power values GPDR registers, and properly save/restore the GAFR + GPDR registers when doing suspend/resume.

This fixes kernel bugzilla 11469: "TUN with 1024 neighbours: ip6_dst_lookup_tail NULL crash" dst->neighbour is not necessarily hooked up at this point in the processing path, so blindly dereferencing it is the wrong thing to do. This NULL check exists in other similar paths and this case was just an oversight. Also fix the completely wrong and confusing indentation here while we're at it.

2008-09-09clockevents: remove WARN_ON which was used to gather informationThomas Gleixner
The issue of the endless reprogramming loop due to a too small min_delta_ns was fixed with the previous updates of the clock events code, but we had no information about the spread of this problem. I added a WARN_ON to get automated information via kerneloops.org and to get some direct reports, which allowed me to analyse the affected machines. The WARN_ON has served its purpose and would be annoying for a release kernel. Remove it and just keep the information about the increase of the min_delta_ns value.
