2016-11-29net: macb: fix the RX queue reset in macb_rx()Cyrille Pitchen
On macb only (not gem), when a RX queue corruption was detected from macb_rx(), the RX queue was reset: during this process the RX ring buffer descriptor was initialized by macb_init_rx_ring() but we forgot to also set bp->rx_tail to 0. Indeed, when processing the received frames, bp->rx_tail provides the macb driver with the index in the RX ring buffer of the next buffer to process. So when the whole ring buffer is reset we must also reset bp->rx_tail so the driver is synchronized again with the hardware. Since macb_init_rx_ring() is called from many locations, currently from macb_rx() and macb_init_rings(), we'd rather add the "bp->rx_tail = 0;" line inside macb_init_rx_ring() than add the very same line after each call of this function. Without this fix, the rx queue is not reset properly to recover from queue corruption and connection drop may occur.

2016-11-29timekeeping: Ignore the bogus sleep time if pm_trace is enabledChen Yu
Power management suspend/resume tracing (ab)uses the RTC to store suspend/resume information persistently. As a consequence the RTC value is clobbered when timekeeping is resumed and tries to inject the sleep time. Commit a4f8f6667f09 ("timekeeping: Cap array access in timekeeping_debug") plugged a out of bounds array access in the timekeeping debug code which was caused by the clobbered RTC value, but we still use the clobbered RTC value for sleep time injection into kernel timekeeping, which will result in random adjustments depending on the stored "hash" value. To prevent this keep track of the RTC clobbering and ignore the invalid RTC timestamp at resume. If the system resumed successfully clear the flag, which marks the RTC as unusable, warn the user about the RTC clobber and recommend to adjust the RTC with 'ntpdate' or 'rdate'.

2016-11-29rtlwifi: Fix enter/exit power_saveLarry Finger
In commit a5ffbe0a1993 ("rtlwifi: Fix scheduling while atomic bug") and commit a269913c52ad ("rtlwifi: Rework rtl_lps_leave() and rtl_lps_enter() to use work queue"), an error was introduced in the power-save routines due to the fact that leaving PS was delayed by the use of a work queue. This problem is fixed by detecting if the enter or leave routines are in interrupt mode. If so, the workqueue is used to place the request. If in normal mode, the enter or leave routines are called directly.

2016-11-29mt7601u: wait for clear rxq when stopping macAnthony Romano
mt7601u_mac_stop_hw should stop polling the rxq once it remains empty but instead continues polling after the rxq status stays clear; bringing down the interface takes about six seconds from this alone. Speed up path by exiting rxq loop once status repeatedly polls empty.
