This reverts commit ae1b22f6. As Linus said in 982d007a: "There was something really messy about cmpxchg8b and clone CPU's, so if you enable it on other CPUs later, do it carefully." This breaks lguest for those configs, but we can fix that by emulating if we have to.

For chips like Niagara2 that have true overflow indications in the %pcr (which we don't actually need and don't use) the interrupt signal persists until the overflow bits are cleared by an explicit %pcr write. Signed-off-by: David S. Miller <davem@davemloft.net>

In bbc_envctrl_init() we have to unlink the fan and temp instances from the lists because our caller is going to free up the 'bp' object if we return an error. We can't rely upon bbc_envctrl_cleanup() to do this work for us in this case. Reported-by: Patrick Finnegan <pat@computer-refuge.org> Signed-off-by: David S. Miller <davem@davemloft.net>

Holding locks over device_del -> kobject_del -> sysfs_deactivate can cause deadlocks if those same locks are grabbed in sysfs show or store methods. The I model s_active count + completion as a sleeping read/write lock. I describe to lockdep sysfs_get_active as a read_trylock, sysfs_put_active as a read_unlock, and sysfs_deactivate as a write_lock and write_unlock pair. This seems to capture the essence for purposes of finding deadlocks, and in my testing gives finds real issues and ignores non-issues. This brings us back to holding locks over kobject_del is a problem that ideally we should find a way of addressing, but at least lockdep can tell us about the problems instead of requiring developers to debug rare strange system deadlocks, that happen when sysfs files are removed while being written to.

The BKL is in this function because of the BKL pushdown (see commit f8f2c79d) It is not needed here because the mutex_lock sonypi_device.lock provides the necessary locking. sonypi_misc_ioctl can be converted to unlocked ioctls since it relies on its own locking (the mutex sonypi_device.lock) and not the bkl Document that llseek is not needed by explictly setting it to no_llseek LKML-Reference: <alpine.LFD.2.00.0910192019420.3563@localhost.localdomain> Signed-off-by: John Kacur <jkacur@redhat.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

We want to be sure that compiler fetches the limit variable only once, so add helpers for fetching current and maximal resource limits which do that. Add them to sched.h (instead of resource.h) due to circular dependency sched.h->resource.h->task_struct Alternative would be to create a separate res_access.h or similar.

Revamp the qdio performance statistics and move them from procfs to debugfs using the seq_file interface. Since the statistics are not intended for the general user the removal of /proc/qdio_perf should not surprise anyone. The per device statistics are disabled by default, writing 1 to /<debugfs mountpoint>/qdio/<device bus ID>/statistics enables the statistics for the given device.
