Dear Thomas and all,

Could you please confirm about the following commit, again?

http://git.armlinux.org.uk/cgit/linux-arm.git/commit/arch/arm/vfp/vfpmodule.c?id=e5b61bafe70477e05e1dce0d6ca4ec181e23cb2a


The avobe commit eliminated the following fix, I think.

http://git.armlinux.org.uk/cgit/linux-arm.git/commit/arch/arm/vfp/vfpmodule.c?id=384b38b66947b06999b3e39a596d4f2fb94f77e4


vfp_force_reload() called from vfp_dying_cpu() does not clear
vfp_current_hw_state[cpu], because cpu stopper task does not own the
context held in the VFP hardware.

Best regards,
 Kohji Okuno
