Hi there John,
I've tested the linux-linaro-natty tree with CONFIG_THUMB2_KERNEL on vexpress, and it seems to work well.
Since we have reasonable confidence in the status of vexpress for Thumb-2 anyway, the start of this cycle seems a good opportunity to switch to Thumb-2 for this platform.
Which packaging tree is the active one for the 11.11 cycle? I guess that would be the appropriate place for this config change.
Cheers ---Dave
Options to add: CONFIG_THUMB2_KERNEL=y CONFIG_THUMB2_AVOID_R_ARM_THM_JUMP11=y (this should get turned on automatically: if so, leave it implicit)
Options to remove: CONFIG_FPE_NWFPE=n CONFIG_FPE_FASTFPE=n

We're just waiting Nicolas Pitre to open the .39 based tree, then John will package it and make it available in a different git tree.
Can you check if you're available to have the same config changes at the .39 vanilla? This way we can check if we're missing any patches even before Nicolas set up his own .39 tree.
Thanks,

v2.6.39 also seems to work, using the same configuration based on the natty packaged kernel tree.

It's coming... it's coming. :-)
