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.
