This patch series fixes several warnings on Intel(R) drivers, including
for igb, igbvf, e1000e, ixgbe, ixgbevf, i40e, i40evf and fm10k.
The primary change is to use BIT() macro where appropriate, and use the
unsigned postfix for various other bitshifts. While much of this change
doesn't prevent any current warnings, it helps ensure that future
additions make use of BIT() macro or the unsigned postfix and prevent
signed bitshift errors in the future. A few places (especially in ixgbe)
don't use BIT even though it's technically equivalent for style and
understanding the real intent of the code.
The series also fixes some other warnings, and makes use of GENMASK in a
few locations.
Changes since v1
- Fixed the last patch in the series to properly resolve the warning
without generating a compilation error.
- Resolved Alex's comments about overzealous use of BIT(). I hope that I
have resolved all his complaints, I fixed up the ethtool version
changes, and other places that I felt were not bit masks. I don't
think I missed any but there are a lot so I could use a few more eyes
on it.
For review, here is the interdiff of the previous series:

Several areas of ixgbe were written before widespread usage of the
BIT(n) macro. With the impending release of GCC 6 and its associated new
warnings, some usages such as (1 << 31) have been noted within the ixgbe
driver source. Fix these wholesale and prevent future issues by simply
using BIT macro instead of hand coded bit shifts.
Also fix a few shifts that are shifting values into place by using the
'u' prefix to indicate unsigned. It doesn't strictly matter in these
cases because we're not shifting by too large a value, but these are all
unsigned values and should be indicated as such.

Make use of GENMASK instead of open coding the equivalent operation
incorrectly.

Also cleanup a case where we're bit shifting a value into place, and use
an unsigned constant. Make use of the unsigned postfix in places where
BIT() macro is not appropriate.

GCC 6 has a new warning which will display when you attempt to left
shift a signed value beyond the storage size of the type. I40E_MASK
generates a mask value for 32bit registers. Properly typecast the mask
value and place the values in parenthesis to prevent macro expansion
issues.

For bitshifts, we should make use of the BIT macro when possible, and
ensure that other bitshifts are marked as unsigned. This helps prevent
signed bitshift errors, and ensures similar style.
Make use of GENMASK and the unsigned postfix where BIT() isn't
appropriate.

To prevent signed bitshift issues, and improve code readability, use the
BIT() macro. Also make use of GENMASK or the unsigned postfix where this
is more appropriate than BIT()

This prevents signed bitshift issues when the shift would overwrite the
signed bit, and prevents making this mistake in the future when copying
and modifying code.
Use GENMASK or the unsigned postfix for cases which aren't suitable for
BIT() macro.

The E1000_ICH_NVM_SIG_MASK value is shifted, out to the 31st bit, which
is the signed bit for signed constants. Mark these values as unsigned to
prevent compiler warnings and issues on platforms which a different
signed bit implementation.

A patch introduced the use of ret_val variable but only assigned it once
and didn't use it. e1000_probe already has a rval variable, which is
what was checked, so remove use of ret_val in favor of rval.
