Some cpu\u0027s\nwill be running the first rendezvous handler and others will be running\nthe second rendezvous handler. Each set waiting for the other set to join\nfor the system wide rendezvous, leading to a deadlock).\n\nMTRR rendezvous sequence is not implemented using stop_machine() as this\ngets called both from the process context aswell as the cpu online paths\n(where the cpu has not come online and the interrupts are disabled etc).\nstop_machine() works with only online cpus.\n\nFor now, take the stop_machine mutex in the MTRR rendezvous sequence that\ngets called from an online cpu (here we are in the process context\nand can potentially sleep while taking the mutex). And the MTRR rendezvous\nthat gets triggered during cpu online doesn\u0027t need to take this stop_machine\nlock (as the stop_machine() already ensures that there is no cpu hotplug\ngoing on in parallel by doing get_online_cpus())\n\n TBD: Pursue a cleaner solution of extending the stop_machine()\n infrastructure to handle the case where the calling cpu is\n still not online and use this for MTRR rendezvous sequence.\n\nfixes: https://bugzilla.novell.com/show_bug.cgi?id\u003d672008\n\nReported-by: Vadim Kotelnikov \u003cvadimuzzz@inbox.ru\u003e\nSigned-off-by: Suresh Siddha \u003csuresh.b.siddha@intel.com\u003e\nLink: http://lkml.kernel.org/r/20110623182056.807230326@sbsiddha-MOBL3.sc.intel.com\nSigned-off-by: H.

The rest I have looked\nat closely and I can\u0027t find any problems.\n\nsetns is an easy system call to wire up. It just takes two ints so I\ndon\u0027t expect any weird architecture porting problems.\n\nWhile doing this I have noticed that we have some architectures that are\nvery slow to get new system calls. cris seems to be the slowest where\nthe last system calls wired up were preadv and pwritev. avr32 is weird\nin that recvmmsg was wired up but never declared in unistd.h. frv is\nbehind with perf_event_open being the last syscall wired up. On h8300\nthe last system call wired up was epoll_wait. On m32r the last system\ncall wired up was fallocate. mn10300 has recvmmsg as the last system\ncall wired up. The rest seem to at least have syncfs wired up which was\nnew in the 2.6.39.\n\nv2: Most of the architecture support added by Daniel Lezcano \u003cdlezcano@fr.ibm.com\u003e\nv3: ported to v2.6.36-rc4 by: Eric W.
