This patch adds a test case for the system wide DSCR default

powerpc provides hcall events that also provides insights into guest
behaviour. Enhance perf kvm to record and analyze hcall events.
- To trace hcall events :
perf kvm stat record
- To show the results :
perf kvm stat report --event=hcall
The result shows the number of hypervisor calls fro

perf kvm can be used to analyze guest exit reasons. This support already
exists in x86. Hence, porting it to powerpc.
- To trace KVM events :
perf kvm stat record
If many guests are running, we can track for a specific guest by using
--pid as in : perf kvm stat rec

Most of header files for tracepoints are located to include/trace/events or
their relevant subdirectories under drivers/. One exception is
include/ras/ras_events.h, which looks inconsistent. So let's move it to the
default places for such headers.

Export 'outcome' and 'action_page_type' to mm.h, so we could use
this emnus outside.
This patch is preparation for adding trace events for memory-failure
recovery action.

For perf to analyze the KVM events like hcalls, we need the
hypervisor calls and their codes to be exported through uapi.
This patch moves most of the pSeries hcall codes from
arch/powerpc/include/asm/hvcall.h to
arch/powerpc/include/uapi/asm/pseries_hcalls.h.
It also moves the mapping from
arch/
To analyze the kvm exits with perf, we will need to map the exit codes
with the exit reasons. Such a mapping exists today in trace_book3s.h.
Currently its not exported to perf.
This patch moves these kvm exit reasons and their mapping from
"arch/powerpc/kvm/trace_book3s.h" to
"arch/powerpc/include
This patch adds an exit reason "RETURN_TO_HOST" for the return code
0x0. Note that this is not related to any interrupt vector address, but
this is added just to make sure that perf doesn't complain if and when a
kvm exit happens with a trap code as 0x0.

Rather than using explicit euid == 0 checks when trying to move
tasks into a cgroup, move permission checks into each specific
cgroup subsystem. If a subsystem does not specify a 'allow_attach'
handler, then we fall back to doing the checks the old way.
This patch adds a 'allow
As a heads up, this is just a first RFC and not a submission.
Android currently loosens the cgroup attchment permissions, allowing
tasks with CAP_SYS_NICE to be able to allow tasks to move arbitrary
tasks across cgroups.
At first glance, overloading CAP_SYS_NICE seems a bit hackish, but this

If CONFIG_CGROUP_NICE_ATTACH is enabled, this implements an

CAP_SYS_NICE to move tasks across mem and cpu cgroups.
