arch/powerpc/kernel/process.c: In function '__switch_to':
arch/powerpc/kernel/process.c:335: error: implicit declaration of function 'account_process_vtime'

This change fixes it. But it will not link 32bit:

kernel/built-in.o(.text+0xbd88): In function `irq_exit':
: undefined reference to `do_softirq'
kernel/built-in.o(.text+0xbde0): In function `local_bh_enable':
: undefined reference to `do_softirq'
kernel/built-in.o(.text+0xbe60): In function `ksoftirqd':
: undefined reference to `do_softirq'
net/built-in.o(.text+0xd6fc): In function `netif_rx_ni':
: undefined reference to `do_softirq'

I think the placement of __ARCH_HAS_DO_SOFTIRQ needs adjustment,
or the code must be moved out of CONFIG_PPC64 in arch/powerpc/kernel/irq.c.
