- Disable tx and rx by resetting hw, so replace rtl8169_asic_down
with rtl8169_hw_reset.
- RxConfig bits 0 ~ 5 have to be cleared before hw reset to avoid
receiving spurious data.
- Certain chips need to do some checking before reset.
- Remove hw reset which is done before hw_start. It is done in close,
down or device probe functions.
- Move rtl8169_init_ring_indexes function into rtl_hw_reset function.
The indexes of tx and rx only need to be zero when the hw resets.

Currently the stack trace per event in ftace is only 8 frames.
This can be quite limiting and sometimes useless. Especially when
the "ignore frames" is wrong and we also use up stack frames for
the event processing itself.
Change this to be dynamic by adding a percpu buffer that we can
write a large stack frame into and then copy into the ring buffer.
For interrupts and NMIs that come in while another event is being
process, will only get to use the 8 frame stack. That should be enough
as the task that it interrupted will have the full stack frame anyway.

While attempting to create a timechart of boot up I found perf didn't
tolerate modules being loaded/unloaded. This patch fixes this by
reading the file once and then writing the size read at the correct
point in the file. It also simplifies the code somewhat.

Software defined version number is not stable enough to be used
in device type naming scheme. The patch changes it to use implicit
soc name for spi device type definition. In this way, we can easily
align the naming scheme with device tree binding, which comes later.
It removes fifosize from spi_imx_data and adds devtype there, so that
fifosize can be set in an inline function according to devtype.
Also, cpu_is_mx can be replaced by inline functions checking devtype.

The only difference between SPI_IMX_VER_0_7 and SPI_IMX_VER_0_4 is
.config function. The patch uses cpu_is_mx35 (to be removed) as the
temporary solution to consolidate functions spi_imx0_4_config and
spi_imx0_7_config into mx31_config. As a result, type SPI_IMX_VER_0_7
can be merged into SPI_IMX_VER_0_4.
It also renames function spi_imx0_4_reset to mx31_reset to keep
consistency with other function naming.
A couple of redundant macros, MX3_CSPISTAT and MX3_CSPISTAT_RR,
together with the useless type SPI_IMX_VER_0_5 also get cleaned up.

It's confusing to use spi_imx2_3 to name SPI_IMX_VER_2_3 function
and macro, as it easily make people think of imx2 and imx3. It's
better to use specific soc name just like what other SPI_IMX_VER
do. For SPI_IMX_VER_2_3 case, it will be mx51. To distinguish it
from CSPI on mx51, mx51_ecspi might be a good choice.

SPI_IMX_VER_0_0 covers i.mx21 and i.mx27. It makes more sense to
use mx21 rather than mx27 to name SPI_IMX_VER_0_0 function and
macro, since i.mx21 comes out ealier than i.mx27.

Since 2.6.36 (23016bf0d25), Linux prints the existence of "epb" in /proc/cpuinfo,
Since 2.6.38 (d5532ee7b40), the x86_energy_perf_policy(8) utility has
been available in-tree to update MSR_IA32_ENERGY_PERF_BIAS.
However, the typical BIOS fails to initialize the MSR, presumably
because this is handled by high-volume shrink-wrap operating systems...
Linux distros, on the other hand, do not yet invoke x86_energy_perf_policy(8).
As a result, WSM-EP, SNB, and later hardware from Intel will run in its
default hardware power-on state (performance), which assumes that users
care for performance at all costs and not for energy efficiency.
While that is fine for performance benchmarks, the hardware's intended default
operating point is "normal" mode...
Initialize the MSR to the "normal" by default during kernel boot.
x86_energy_perf_policy(8) is available to change the default after boot,
should the user have a different preference.

Since the A4LC should only be powered off if the A3RV is off, make
the A4LC's power down routine return -EBUSY if A3RV is not off to
indicate to the core that it doesn't want to power off the domain in
that case. This will cause the core to regard A4LC as active, so
the pm_genpd_poweron() in pd_power_down_a3rv() is not necessary any
more.

Currently pm_genpd_poweroff() discards error codes returned by
the PM domain's .power_off() callback, because it's safer to always
regard the domain as inaccessible to drivers after a failing
.power_off(). Still, there are situations in which the low-level
code may want to indicate that it doesn't want to power off the
domain, so allow it to do that by returning -EBUSY from .power_off().

tg3 devices will need to know exactly what function number they are so
that they can communicate their status to the other functions. In a KVM
environment, the function number of a device presented by the kernel
might not be the true function number, so an alternative method to
determine the function number is needed.
This patch used to contain an implementation for the alternative method,
but recently we discovered a hardware bug that renders it incorrect.
While new method is not yet known, it is still useful to consolidate the
code that determines the PCI function to one location and use the
results throughout the code.

Currently pci_set_power_state() does not return useful return codes for
transitions to the D0 power state. If a device refuses to go into D0,
the PCI layer issues a warning but returns success.
Entering into D0 is a requirement for correct operation of tg3 devices
though. If the PCI layer should be changed to return an error code for
this type of failure, the tg3 driver would be interested in catching it
and reacting to it. This patch makes the necessary modifications.
