2018-08-30rcutorture: Test early boot call_srcu()Paul E. McKenney
Now that SRCU permits call_srcu() to be invoked at early boot, this commit ensures that the rcutorture scripting tests early boot call_srcu(). Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
2018-08-30rcu: Stop testing RCU-bh and RCU-schedPaul E. McKenney
Now that the RCU-bh and RCU-sched update-side functions are simple wrappers around their RCU counterparts, there isn't a whole lot of point in testing them. This commit therefore removes the self-test capability and removes the corresponding kernel-boot parameters. It also updates the various rcutorture .boot files to remove the kernel boot parameters that call for testing RCU-bh and RCU-sched. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
2018-08-30perf annotate: Handle arm64 move instructionsKim Phillips
Add default handler for non-jump instructions. This really only has an effect on instructions that compute a PC-relative address, such as 'adrp,' as seen in these couple of examples: BEFORE: adrp x0, ffff20000aa11000 <kallsyms_token_index+0xce000> AFTER: adrp x0, kallsyms_token_index+0xce000 BEFORE: adrp x23, ffff20000ae94000 <__per_cpu_load> AFTER: adrp x23, __per_cpu_load The implementation is identical to that of s390, but with a slight adjustment for objdump whitespace propagation (arm64 objdump puts spaces after commas, whereas s390's presumably doesn't). The mov__scnprintf() declaration is moved from s390's to arm64's instructions.c because arm64's gets included before s390's. Committer testing: Ran 'perf annotate --stdio2 > /tmp/{before,after}' no diff.
