Hi Kumar, Can you please review this patch set.

Move the E.HV check to the cpu setup code. Based on this check we > manipulte the > CPU_FTR_EMB_HV flag (added as a part of e500mc KVM support) in the > cpu_spec > structure. We determine the presence of this feature based on the > MMUCFG[LPIDSIZE] > check and decide if we can setup the E.HV mode ivors. > 2. Merge the 32 bit cpu setup code for e500mc/e5500 and define the > "cpu_restore" > routine (for e5500/e6500) only for the 64 bit case. The cpu_restore > routine > is used in the 64 bit case for setting up the secondary cores. > 3. For the 64 bit case separate out e5500 cpu_setup and cpu_restore > functions. > The cpu_setup function (for the primary core) is passed the cpu_spec > pointer, > which is not there in case of the cpu_restore function. Also, in our > case > we will have to manipulate the CPU_FTR_EMB_HV flag on the the primary > core. > 4. Added CPU_FTR_EMB_HV check for e5500. > > Varun Sethi (4): > Separate out E.HV check and ivor setup code. > Merge the PPC 32 e5500 setup code with e500mc setup and don't define > a restore routine for PPC 32. > Separate out restore_e5500/setup_e5500 routines and check for E.HV > mode before setting ivor setting code. > Add CPU_FTR_EMB_HV check for e5500. > > arch/powerpc/kernel/cpu_setup_fsl_booke.S | 74 > +++++++++++++++++++++++++---- > arch/powerpc/kernel/cputable.c | 4 ++ > arch/powerpc/kernel/exceptions-64e.S | 18 +------ > arch/powerpc/kernel/head_fsl_booke.S | 18 ++----- > 4 files changed, 75 insertions(+), 39 deletions(-) > > -- > 1.7.4.1 -- To unsubscribe from this list: send the line "unsubscribe kvm-ppc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
