Subject: [patch 0/4] perf/x86, jump_label: Cure serialization issues

Yue and Xingwei reported a syzkaller crash related to the rdpmc attribute
file and jump labels. It turns out to be lack of serialization in the
attribute write path and non-robustness on the jump label side.

The following series addresses these issues.

Thanks,

	tglx
