Adapt to the rseq.h API changes introduced by commits
"selftests/rseq: <arch>: Template memory ordering and percpu access mode".
Build a new basic_percpu_ops_mm_cid_test to test the new "mm_cid" rseq
field.

selftests/rseq: Fix ppc32 offsets by using long rather than off_t2022-02-02T12:11:36+00:00Mathieu Desnoyersmathieu.desnoyers@efficios.com2022-01-24T17:12:48+00:00urn:sha1:26dc8a6d8e11552f3b797b5aafe01071ca32d692
The semantic of off_t is for file offsets. We mean to use it as an
offset from a pointer. We really expect it to fit in a single register,
and not use a 64-bit type on 32-bit architectures.
Fix runtime issues on ppc32 where the offset is always 0 due to
inconsistency between the argument type (off_t -> 64-bit) and type
expected by the inline assembler (32-bit).

selftests/rseq: remove ARRAY_SIZE define from individual tests2021-12-11T00:51:03+00:00Shuah Khanskhan@linuxfoundation.org2021-12-09T23:19:09+00:00urn:sha1:07ad4f7629d4802ff0d962b0ac23ea6445964e2a
ARRAY_SIZE is defined in several selftests. Remove definitions from
individual test files and include header file for the define instead.
ARRAY_SIZE define is added in a separate patch to prepare for this
change.
Remove ARRAY_SIZE from rseq tests and pickup the one defined in
kselftest.h.

rseq/selftests: Provide basic percpu ops test2018-06-06T09:58:35+00:00Mathieu Desnoyersmathieu.desnoyers@efficios.com2018-06-02T12:44:06+00:00urn:sha1:01a5ec4217599fd78ba76fa7199a350c5fb4650f
"basic_percpu_ops_test" is a slightly more "realistic" variant,
implementing a few simple per-cpu operations and testing their
correctness.
