Subject: [PATCH 1/1] powerpc/hv-24x7: Add missing put_cpu_var()
Add missing put_cpu_var() for 24x7 requests. This went missing in

- Split independent changes in patch 2 into patch 3.

Sukadev Bhattiprolu (10):
powerpc/hv-24x7: Modify definition of request and result
Use pr_devel_ratelimited() to log error message when the 24x7 HCALL
fails. Since users specify events by their sysfs name, the HCALL should
succeed. Any errors reported by the HCALL would be of interest to the
developer, rather than the user/administrator.

Ok. Will fix up parameter alignment with
rchitectures/PMUs that don't need the READ transaction types
simply ignore the ->start_txn() and ->commit_txn() calls.
Sukadev Bhattiprolu (5):
perf: Add a flags parameter to pmu txn interfaces
perf: Split perf_event_read() and perf_event_count()
perf: Rename perf_event_r
interface and have the PMUs cache the transaction type.
But that would need slightly more intrusive changes in all PMUs
to support a second transaction type.
Thanks to Peter Zijlstra for his input.

using the transaction interface, we would sometimes need one but
not both.
Break up perf_event_read() and have it just read/update the counter
and have the callers compute the total count if necessary.

mfspr() and related macros will be needed in two separate files.

Used in follow-on patches to parse event files.

lows parsing Intel style JSON event files. This
allows to use an Intel event list directly with perf. The Intel event lists
can be quite large and are too big to store in unswappable kernel memory.
The conversion from JSON to C-style is straight forward. The parser knows

m not fully sure this change to the scanner is correct
(what was the dot special case good for?), but I haven't
found anything that breaks with it so far at least.
V2: Add the dot to name too, to handle events outside cpu//

Implement code that returns the generic CPU ID string for Powerpc.
This will be used to identify the specific table of PMU events to
parse/compare user specified events against.
