powerpc: Move branch instruction from ACCOUNT_CPU_USER_ENTRY to caller
[PATCH 1/6] powerpc: Move branch instruction from ACCOUNT_CPU_USER_ENTRY to caller The first instruction in ACCOUNT_CPU_USER_ENTRY is 'beq' which checks for exceptions coming from kernel mode. PPR value will be saved immediately after ACCOUNT_CPU_USER_ENTRY and is also for user level exceptions. So moved this branch instruction in the caller code.
