Hi all,
Today's linux-next merge of the percpu tree got a conflict in
kernel/softlockup.c between commit
b460e1994445b5ebb97aaec0c29f893c246bd830 ("softlockup: add
sched_clock_tick() to avoid kernel warning on kgdb resume") from the kgdb
tree and commit 1871e52c76dd95895caeb772f845a1718dcbcd75 ("percpu: make
percpu symbols under kernel/ and mm/ unique") from the percpu tree.
Just context changes. I fixed it up (see below) and can carry the
changes as necessary.
I do wonder if the local variable name changes in the percpu tree change
were a good idea?
I also needed a further merge fixup (see further below).
