Use the newly introduced owner field in struct gpio_chip to protect the
current (small) set of non-SOC GPIO drivers from being unloaded while any of
their GPIOs are in use.

As long as one or more GPIOs on a gpio chip are used its driver should not be
unloaded. The existing mechanism (gpiochip_remove failure) doesn't address
that, since rmmod can no longer be made to fail by having the cleanup code
report errors. Module usecounts are the solution.
Assuming standard "initialize struct to zero" policies, this change won't
affect SOC platform drivers. However, drivers for external chips (on I2C and
SPI busses) should be updated if they can be built as modules.

Prohibit users from probing preempt_schedule(). One way of prohibiting the
user from probing functions is by marking such functions with __kprobes. But
this method doesn't work for those functions, which are already marked to
different section like preempt_schedule() (belongs to __sched section). So we
use blacklist approach to refuse user from probing these functions.
In blacklist approach we populate the blacklisted function's starting address
and its size in kprobe_blacklist structure. Then we verify the user specified
address against start and end of the blacklisted function. So any attempt to
register probe on blacklisted functions will be rejected.

Updates to the i.MX SPI controller driver:
1) Some comments changed and/or added.
2) End of transfers is now managed on TXFIFO empty interrupt after the
last write to TXFIFO. This speeds interrupt execution by removing
the wait for TXFIFO to become empty. On TXFIFO empty interrupt the
handler needs only to poll for the end of the ongoing transaction
(SPI_CONTROL_XCH) to close the transfer.
(2.1) Write only transfers are closed flushing RXFIFO.
(2.2) Read transfers are closed reading trailing bytes from RXFIFO.
(2.3) Read transfers where RXFIFO overrun occurred are closed by
flushing RXFIFO and aborting the message.
3) Fifos are now flushed via SPI disable after the end of ongoing
transaction.

Thomas Koeller had reported an issue where a device that had been making use
of the UART_BUG_TXEN code in the 8250 driver was mistakenly being caught by
the backup timer test, causing the device to work improperly.
To fix this, tighten the test requirements to enable the backup timer
workaround.
The backup timer is really meant to catch UARTs that don't re-assert the THRE
interrupt. The expectation is that they do initially assert THRE. This patch
clarifies the test.

pci_serial_quirks contains a number of function pointers where the referenced
