For time being, you can ignore about ARM64.
let's have a discussion on ARMv7 first.
I have enabled generic arch arm timer in kernel 3.10 frame work to
validate vDSO (ARM: vDSO -> still, it did not merge in the vanilla kernel)
on ARMv7. As part of this, i have noticed that the contex lost is
happening. After pulling the patch, the issue is resolved, timer/counter
is up and running. In future, someone wants to enable arch timer in 3.10,
then I anticipate that the patch needs to be merged in vanilla kernel.
correct me if I am wrong.
