[PATCH 0/1] linux-yocto/3.4: move PREEMPT_NONE to beagleboard standard kernel only

[Bruce Ashfield]

Richard/Saul,

Just a minor kernel configuration tweak for anyone that wants
to try out preempt-rt on the beagleboard. This is the result 
of a conversion on the yocto list recently, and is a simple change
to make life easier for those experimenting with -rt support
on this board.

(this is stacked on top of the change I just sent for validate
branches, shout if you need that changed).

Cheers,

Bruce

[PATCH 1/1] linux-yocto/3.4: move PREEMPT_NONE to beagleboard standard kernel only

[Bruce Ashfield]

A recent report of the preempt-rt beagleboard kernel not enabling full
-rt preemption out of the box revealed that the existing fix for SD
boot issues (which were fixed by disabling preemption) was the root
cause for the options not being enabled.

Although the fix for the SD card detection issues is still valid, it
also doesn't make sense to apply it to a kernel type that only exists
to support enhanced preemption. Since many variants of the board boot
with preemption enabled, opening the possibility of a boot problem is
acceptable, given that it allows the -rt kernel to be used.
