Add PMU_RANGE_ATTR() and PMU_RANGE_RESV() (for reserved areas) which
generate functions to extract the relevent bits from
event->attr.config{,1,2} for use by sw-like pmus where the
'config{,1,2}' values don't map directly to hardware registers.

These patches add basic pmus for 2 powerpc hypervisor interfaces to obtain

The counters supplied by these interfaces are continually counting and never

This provides a basic interface between hv_24x7 and perf. Similar to
the one provided for gpci, it lacks transaction support and does not
list any events.

This provides a basic link between perf and hv_gpci. Notably, it does
not yet support transactions and does not list any events (they can

24x7 (also called hv_24x7 or H_24X7) is an interface to obtain
performance counters from the hypervisor. These counters do not have a
fixed format/possition and are instead documented in a "24x7 Catalog",
which is provided by the hypervisor (that interface is also documented
in this header).
This
"H_GetPerformanceCounterInfo" (refered to as hv_gpci or just gpci from

other data from the hypervisor. All outputs have a fixed format (and

[Patch depends on another patch in this series that introduces raw_cpu_ops]
We define a check function in order to avoid trouble with the
include files. Then the higher level __this_cpu macros are
modified to invoke the preemption check.

[Patch depends on another patch in this series that introduces raw_cpu_ops]
The RT_CACHE_STAT_INC macro triggers the new preemption checks
for __this_cpu ops.
I do not see any other synchronization that would allow the use
of a __this_cpu operation here however in commit
[Patch depends on another patch in this series that introduces raw_cpu_ops]
With the preempt checking logic for __this_cpu_ops we will get false
positives from locations in the code that use numa_node_id.
Before the __this_cpu ops where introduced there were
no checks for preemption present

[Patch depends on another patch in this series that introduces raw_cpu_ops]
Convert uses of __get_cpu_var for creating a address from a percpu
offset to this_cpu_ptr.
The two cases where get_cpu_var is used to actually access a percpu
variable are changed to use this_cpu_read/raw_cpu_read.

These are generally replaced with raw_cpu_ptr. However, in
gic_get_percpu_base() we immediately dereference the pointer. This is
equivalent to a raw_cpu_read. So use that operation there.
