Hi David,
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Addition of explicit scheduling points to map alloc/free
in order to avoid having to hold the CPU for too long,
from Eric.
2) Fixing of a corruption in overlapping perf_event_output
calls from different BPF prog types on the same CPU out
of different contexts, from Daniel.
3) Fallout fixes for recent correction of broken uapi for
BPF_PROG_TYPE_PERF_EVENT. um had a missing asm header
that needed to be pulled in from asm-generic and for
BPF selftests the asm-generic include did not work,
so similar asm include scheme was adapted for that
problematic header that perf is having with other
header files under tools, from Daniel.

Thanks a lot!
