In certain scenarios - e.g. seccomp filtering with ERRNO as default action -
the system call fails for other reasons than the syscall not being available.
The seccomp filter can be configured to store a user-defined error code on
return from a blacklisted syscall. Don't always set ENOSYS on
The secure_computing_strict will just force the kernel to panic on
secure_computing failure. Once SECCOMP_FILTER support is enabled in the kernel,
syscalls can be denied without system failure.

Add the missing pieces in order to enable SECCOMP_FILTER on PowerPC
architectures, and enable this support.
Testing has been pursued using libseccomp with the latest ppc support patches
[1][2], on Freescale platforms for both ppc and ppc64. Support on ppc64le has
also been tested, courtesy of
Due to the introduction of the raw_spinlock for the KVM openpic, guests with a

This patch enables running intensive I/O workloads, e.g. netperf, in a guest

This patchset enables running KVM SMP guests with external interrupts on an
underlying RT-enabled Linux. Previous to this patch, a guest with in-kernel MPIC
emulation could easily panic the kernel due to preemption when delivering IPIs
and external interrupts, because of the openpic spinlock

Well I'm tired of discussing this. I don't think what you
proposed makes sense, putting 3.4MB[1] of changing blob into perf.
I'll resubmit the JSON parser without the downloader. Then users
have the option to get their own events and use that.
If you don't like that, standard perf just has to

We currently read the information about idle states from the DT
so as to populate the cpuidle table. Use those APIs to read from
the DT that can avoid endianness conversions of the property values
in the cpuidle driver.
