2009-09-21ARM: 5718/1: Sane busids for RealView board componentsLinus Walleij
This removes the totally bogus bus ID:s with two-digit hex numerals either referring to the base address of corresponding versatile machine or just some arbitrarily chosen digit in favor of just using the device identifier as a string. I kept the "dev:" prefix for DevChips, "fpga:" prefix for FPGA:s and "issp:" prefix for the other processor bus, just in case someone likes them.

2009-09-21ARM: 5715/1: Make kprobes unregistration SMP safeFrederic Riss
ARM kprobes use an illegal instruction to trigger kprobes. In the current implementation, there's a race between the unregistration of a kprobe and the illegal instruction exception handler if they run at the same time on different cores. When reading the value of the undefined instruction, the exception handler might get the original legal instruction as just patched concurrently by arch_disarm_kprobe(). When this happen the kprobe handler won't run, and thus the exception handler will oops because it believe it just hit an undefined instruction in kernel space. The following patch synchronizes the code patching in the kprobes unregistration using stop_machine and thus avoids the above race.

2009-09-21nfs: initialize the backing_dev_info when creating the serverJens Axboe
NFS may free the server structure without ever having used the bdi, so we either need to flag the bdi as being uninitialized or initialize it up front. This does the latter. This fixes a crash with mounting more than one NFS file system, should people ever need that kind of obscure NFS functionality.

2009-09-21trivial: doc: hpfall: reduce risk that hpfall can do harmChristian Thaeter
Improve the example code to be at least useable, as in not causing harm (as shown below). Code can still be improved further, but this adds some basic safeguards. 1. hpfall *MUST* mlockall(MCL_CURRENT|MCL_FUTURE); itself! Since the Program sits and waits most of the time it becomes very likely swapped out. If it gets woken up when the laptop drops from the table while it is swapped out it actually triggers harddrive activity! 2. Daemonize hpfall using 'daemon(0,0)' (quick and dirty). 3. Give hpfall realtime priority. Should give a chance that it has less latency when woken up.
