assortment of timer, watchdog, interrupt

These are a bunch of small things I've built up from looking through code trying to track down some rare irq latency issues.

None of them actually fix any long irq latencies, but they hopefully make the code a bit neater, get rid of some small glitches, increase watchdog coverage etc.

Ben spotted a bug with the first patch last time I posted, that's fixed.

Thanks,
Nick

powerpc/64: irq_work avoid interrupt when called with hardware irqs
enabled
powerpc/pseries: put cede MSR[EE] check under IRQ_SOFT_MASK_DEBUG powerpc/64s: make PACA_IRQ_HARD_DIS track MSR[EE] closely powerpc/64s: micro-optimise __hard_irq_enable() for mtmsrd L=1 support powerpc/64: remove start_tb and accum_tb from thread_struct powerpc/pseries: lparcfg calculate PURR on demand
powerpc: generic clockevents broadcast receiver call
tick_receive_broadcast
powerpc: allow soft-NMI watchdog to cover timer interrupts with large
decrementers
powerpc: move timer broadcast code under GENERIC_CLOCKEVENTS_BROADCAST
ifdef
powerpc: move a stray NMI IPI case under NMI_IPI ifdef powerpc/time: account broadcast timer event interrupts separately
