Erez Shitrit 7ae31c620d net/mlx5: DR, use non preemptible call to get the current cpu number
commit c0702a4bd41829f05638ec2dab70f6bb8d8010ce upstream.

Use raw_smp_processor_id instead of smp_processor_id() otherwise we will
get the following trace in debug-kernel:
	BUG: using smp_processor_id() in preemptible [00000000] code: devlink
	caller is dr_create_cq.constprop.2+0x31d/0x970 [mlx5_core]
	Call Trace:
	dump_stack+0x9a/0xf0
	debug_smp_processor_id+0x1f3/0x200
	dr_create_cq.constprop.2+0x31d/0x970

	genl_rcv_msg+0xb8/0x160
	netlink_rcv_skb+0x11e/0x340

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
