====================
mlx5 driver updates

This series includes some bug fixes and updates for the mlx5 core
and ethernet driver.

From Gal, two fixes that protects the update CQ moderation flows
when it is not allowed.

From Moshe, two fixes for the core and ethernet driver in
non-cached(NC) and write combining(WC) buffers mappings,
which prevents the driver from double memory mappings.

From Or, reduce the firmware command completion timeout.

From Tariq, several small trivial fixes.

Changes from v0:
	- "Fix global UAR mapping" commit messages updated to explain ARCH_HAS_IOREMAP_WC usage.
	- rebased to commit 8d3f2806 'Merge branch ethtool-ksettings'

Changes from v1:
	- Removed ARCH_HAS_IOREMAP_WC config flag from "Fix global UAR mapping" commit,	as it was not accurate to use it.
	- Squashed "Fix global UAR mapping" and "net/mlx5: Avoid double mapping of io mapped memory"
	- Added more info for "Fix global UAR mapping" in commit message

Changes from v2:
	- None. resubmission per Dave's request due to two parallel submissions to mlx5 driver.
