Modifications are aimed specifically at the e500mc/e5500 cpu setup code. Following modifications are introduced by this patchset: 1. 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
