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!
