New Revision: 211176
URL: http://svn.freebsd.org/changeset/base/211176

Log:
  IPI handlers may run generally with interrupts disabled because they
  are served via an interrupt gate.
However, that doesn't explicitly prevent preemption and thread
  migration thus scheduler pinning may be necessary in some handlers.
  Fix that.
Tested by: gianni
  MFC after:    1 month

Actually that does prevent preemption if you do not call any code that would schedule a thread. I think this change is all safe to revert.
