This patch applies the introduced memalloc_noio_save() and

This patch applyes the introduced pm_runtime_set_memalloc_noio on
block device so that PM core will teach mm to not allocate memory with

This patch let glue driver return -EPROBE_DEFER if the transceiver
is not readly, so we can support defer probe on musb to fix the
below error on 3.7-rc5 if transceiver drivers are built as module:
[ 19.052490] unable to find transceiver of type USB2 PHY
[ 19.072052] HS USB OTG: no transceiver
In the fail1~fail5 failure path, pm_runtime_disable() should
be called to avoid 'Unbalanced pm_runtime_enable' error in
next probe() which may be triggered by defer probe or next
'modprobe musb_hdrc'.

This patch is to expose usb port's pm qos flags(pm_qos_no_power_off,
pm_qos_remote_wakeup) to user space. User can set pm_qos_no_power_off

Whenever an URB is programmed for transfer, the TXFIFO
is flushed. This results in valid packets of the
previous transfer to get flushed when double buffering
is enabled (The MUSB_TXCSR_FIFONOTEMPTY bit in TXCSR
is set indicating that a packet in the FIFO is yet to be sent)
