2016-03-01parisc: Fix ptrace syscall number and return value modificationHelge Deller2-6/+15
Mike Frysinger reported that his ptrace testcase showed strange behaviour on parisc: It was not possible to avoid a syscall and the return value of a syscall couldn't be changed. To modify a syscall number, we were missing to save the new syscall number to gr20 which is then picked up later in assembly again. The effect that the return value couldn't be changed is a side-effect of another bug in the assembly code. When a process is ptraced, userspace expects each syscall to report entrance and exit of a syscall. If a syscall number was given which doesn't exist, we jumped to the normal syscall exit code instead of informing userspace that the (non-existant) syscall exits. This unexpected behaviour confuses userspace and thus the bug was misinterpreted as if we can't change the return value. This patch fixes both problems and was tested on 64bit kernel with 32bit userspace.

2016-03-01ALSA: seq: oss: Don't drain at closing a clientTakashi Iwai3-19/+0
The OSS sequencer client tries to drain the pending events at releasing. Unfortunately, as spotted by syzkaller fuzzer, this may lead to an unkillable process state when the event has been queued at the far future. Since the process being released can't be signaled any longer, it remains and waits for the echo-back event in that far future. Back to history, the draining feature was implemented at the time we misinterpreted POSIX definition for blocking file operation. Actually, such a behavior is superfluous at release, and we should just release the device as is instead of keeping it up forever. This patch just removes the draining call that may block the release for too long time unexpectedly.

2016-03-01cpufreq: mediatek: allow building as a moduleArnd Bergmann2-2/+3
The MT8173 cpufreq driver can currently only be built-in, but it has a Kconfig dependency on the thermal core. THERMAL can be a loadable module, which in turn makes this driver impossible to build. It is nicer to make the cpufreq driver a module as well, so this patch turns the option in to a 'tristate' and adapts the dependency accordingly. The driver has no module_exit() function, so it will continue to not support unloading, but it can be built as a module and loaded at runtime now.
