Mahesh Salgaonkar 8d81296cfc powerpc/radix: Remove trace_tlbie call from radix__flush_tlb_all 
radix__flush_tlb_all() is called only in kexec path in real mode and any
tracepoints at this stage will make kexec to fail if enabled.

To verify enable tlbie trace before kexec.

$ echo 1 > /sys/kernel/debug/tracing/events/powerpc/tlbie/enable
== kexec into new kernel and kexec fails.

Fix this by not calling trace_tlbie from radix__flush_tlb_all().
