Subject: [PATCH 01/48] percpu: Add raw_cpu_ops
Date: Fri, 14 Feb 2014 14:18:42 -0600 [thread overview]
Message-ID: <20140214201903.981514985@linux.com> (raw)
In-Reply-To: 20140214201841.826179349@linux.com
[-- Attachment #1: raw_cpu_ops --]
[-- Type: text/plain, Size: 30324 bytes --]
The patches following this one will add preemption checks to __this_cpu
ops so we need to have an alternative way to use this_cpu operations
without preemption checks.
raw_cpu_ops will be the basis for all other ops since these will be the
operations that do not implement any checks.
Primitive operations are renamed by this patch from __this_cpu_xxx to
raw_cpu_xxxx.
Also change the uses of the x86 percpu primitives in preempt.h.
These depend directly on asm/percpu.h (header #include nesting issue).
V1->V2:
- move __this_cpu_ptr legacy definition to include/asm-generic/percpu.h
- Merge formerly separate x86 pieces because some x86 code in preempt.h
relies on __this_cpu_ops/raw_cpu_ops to not fall back.
