Author: dchagin Date: Sun May 24 15:54:58 2015 New Revision: 283422 URL: https://svnweb.freebsd.org/changeset/base/283422
Log: Refund the proc emuldata struct for future use. For now move flags from thread emuldata to proc emuldata as it was originally intended. As we can have both 64 & 32 bit Linuxulator running any eventhandler can be called twice for us. To prevent this move eventhandlers code from linux_emul.c to the linux_common.ko module.
