Noop scheduler currently dispatches a request by calling
elv_dispatch_sort(). In practice, sorting does not occur because
__elv_next_request() asks the io scheduler to dispatch a request
only when elevator queue is empty.
Also, not reordering requests seems more appropriate for noop. This

Hi all-
We've considered two approaches to dealing with NMIs:
1. Allow nesting. We know quite well how messy that is.
2. Forbid IRET inside NMIs. Doable but maybe not that pretty.
We haven't considered:
3. Forbid faults (other than MCE) inside NMI.

This patch fixes a bug in which the timer routine synchronized
against the ethtool-triggered statistics updates with spin_lock_bh().
A timer function is itself a bottom-half, so this should be
spin_lock().

This patch set contains bug fixes and enhencements of hw ethernet
statistics processing on TI's Keystone2 CPSW ethernet switches.
v1: Removes unused defines in PATCH 3/6 based on reviewer's comment
WingMan Kwok (6):
net: netcp: Fixes the use of spin_lock_bh in timer function
net: netcp:
This patch fixes error in the setting of the hw statistics
module base for K2HK platform. In K2HK although there are
4 hw statistics modules, but only 2 are visible at a time.
Thus when setting up the pointers to the base of the
corresponding hw statistics modules, modules 0 and 2 should
point to
In certain applications it's beneficial to allow the CPSW h/w
stats counters to continue to increment even while the kernel
polls them. This patch implements this behavior for both 1G
and 10G ethernet subsystem modules.

This depends on the patch moving pm8941-wled to backlight [1]. The dt property

Some of the block comment tests that are used only for networking are

For example, these styles are not encouraged:

As of cf991de2f614 ("x86/asm/msr: Make wrmsrl_safe() a function"),
wrmsrl_safe is a function, but wrmsrl is still a macro. The wrmsrl
macro performs invalid shifts if the value argument is 32 bits.
This makes it unnecessarily awkward to write code that puts an
unsigned long into an MSR.
