I tested this scenario with the latest linux-next kernel with the subject patch applied and thumb-2 mode enabled. I could successfully hotplug in/out CPU1 a couple of times. However, if done back to back it hangs (without any crash dump even with low level debug enabled). Is this the same behavior that you observe?
Hmm.. Not at all..
I just tested this on latest linux-next: d24511f ARM: EXYNOS: Fix hotplug when CPUs are booted in HYP mode fb4a940 Add linux-next specific files for 20140213 b816300 Merge branch 'akpm/master'
With $subject patch applied (attached too)..
And this is what I get on a ubuntu system (attaching my .config as well which I made from exynos_defconfig+THUMB2)..
With your attached patch, I too observe a similar crash with the above mentioned configuration (exynos_defconfig + THUMB2).
