This is almost identical set of patches recently done for s390.
With this, user can run perf trace without libaudit on powerpc
as well. Ex,
$ make
... libaudit: [ OFF ]
$ ./perf trace ls
0.221 ( 0.005 ms): ls/43330 open(filename: 0xac1e2778, flags: CLOEXEC ) =
3
0.227 ( 0.
Will be used for generating the syscall id/string translation table.

This should speed up accessing new system calls introduced with
the kernel rather than waiting for libaudit updates to include
them.

This should speed up accessing new system calls introduced with the
kernel rather than waiting for libaudit updates to include them.
It also enables users to specify wildcards, for example, perf trace -e
'open*', just like was already possible on x86 and s390.

If the affine portal for a specific CPU is offline at boot time
affine its interrupt to CPU 0. If the CPU is later brought online
the hotplug handler will correctly adjust the affinity.

I no longer have any hardware with the Apple motion sensor and thus
relinquish maintainership of the driver.

For testing purposes I wrote a small program that performs stvx/lvx using the

This patch provides the MMIO load/store vector indexed
