whether PMD is changed or not. So IPI broadcast in radix pmd collapse
flush is not necessary anymore. But it is still needed for hash TLB.

sam440ep_setup_rtc is just called by machine_device_initcall, and it calls
i2c_register_board_info which is init too, so the lack of __init may cause
mismatch warning when linking kernel.

fix e500_tlb.h to reflect the change and fix e500_tlb.c to align with the

With the latest kernel building KVM for PPC, got integer overflow
error in kvm_main.c file. The root cause is that compiler consider
KVM_PAGES_PER_HPAGE as signed long type, however it should be
unsigned long type.
So, change it to unsigned long type in include/asm/kvm_host.h
