[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

The first instruction in ACCOUNT_CPU_USER_ENTRY is 'beq' which checkes 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.
