[GIT PULL de-alpha] Make core code not need to know about Alpha for v4.15

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello, Ingo,

This series is a first step towards making the core kernel no longer
need to consider DEC Alpha as a special case.  This is accomplished
by two sets of patches, followed by a Coccinelle script:

1.	Patches 1/19 through 15/19 in the following patches, which
	change non-Coccinelle-susceptible instances of ACCESS_ONCE()
	to either READ_ONCE() or WRITE_ONCE(), as appropriate.	Most of
	these patches are courtesy of Mark Rutland.

2.	Patches 16/19 through 18/19 in the following patches, which
	add smp_read_barrier_depends() to READ_ONCE() and to Alpha's
	value-returning _release and _relaxed atomic read-modify-write
	operations, while also removing lockless_dereference() in favor
	of the modified READ_ONCE().

3.	A patch generated by Coccinelle (script in commit log) that
	converts ACCESS_ONCE() to either READ_ONCE() or WRITE_ONCE(),
	as appropriate.  Of course, this patch should not be applied
	as-is to mainline, instead, the Coccinelle script should be
	re-run in order to account for any changes between now and
	the time of merging into mainline.

A later series (most likely targeted to v4.16) will remove instances of
smp_read_barrier_depends() that are made redundant by this series, that
is to say, almost all of them.

These changes are available in the git repository at:
