[PATCH v2 0/4] powerpc/perf: Miscellaneous fixes

[Sukadev Bhattiprolu]

Miscellaenous fixes for perf and 24x7 counters in powerpc.

Patches 1,3,4 were submitted earlier as a part of the parametrized
events for 24x7 counters. But they are not directly related to the
parametrized events.

Patch 2 simplifies and fixes a bug in catalog_read() which causes the
catalog file to not read first page.

Changelog[v2]
	Rebase to perf/core tree.

Cody P Schafer (3):
  powerpc/perf/hv-24x7: use kmem_cache instead of aligned stack
    allocations
  perf Documentation: sysfs events/ interfaces
  perf Documentation: remove duplicated docs for powerpc cpu specific
    events

Sukadev Bhattiprolu (1):
  Simplify catalog_read()

[PATCH v2 1/4] powerpc/perf/hv-24x7: use kmem_cache instead of aligned stack allocations

[Sukadev Bhattiprolu]

From: Cody P Schafer <cody@linux.vnet.ibm.com>

Ian pointed out the use of __aligned(4096) caused rather large stack
consumption in single_24x7_request(), so use the kmem_cache
hv_page_cache (which we've already got set up for other allocations)
insead of allocating locally.

No space after the * please.

You never use the struct name so this can be anonymous, eg:

	struct {
		struct hv_24x7_data_result_buffer buf;
		...

No space again.

Why aren't we using kzalloc here?

It looks like we're initialising everything below except the reserved fields,
but are they allowed to be non-zero? It's probably safer to just kzalloc it.

If prefer labels to be named for what they do, so this would be just "out".

And this would be "out_free_request_buffer".

Wouldn't this be better as:

	*res = be64_to_cpu(result_buffer->result);

out_free_result_buffer:
	kfree(result_buffer);
out_free_request_buffer:
	kfree(request_buffer);
out:

[PATCH v2 2/4] Simplify catalog_read()

[Sukadev Bhattiprolu]

catalog_read() implements the read interface for the sysfs file

	/sys/bus/event_source/devices/hv_24x7/interface/catalog

It essentially takes a buffer, an offset and count as parameters
to the read() call.  It makes a hypervisor call to read a specific
page from the catalog and copy the required bytes into the given
buffer. Each call to catalog_read() returns at most one 4K page.

Given these requirements, we should be able to simplify the
catalog_read().

I don't see where page_count is used.

Shouldn't offset_in_page be based on offset ?

From: Cody P Schafer <cody@linux.vnet.ibm.com>

Listing specific events doesn't actually help us at all here because:
 - these events actually vary between different ppc processors, they
   aren't garunteed to be present.
 - the documentation of the (generic) file contents is now superceded by the
   docs for arbitrary event file contents.

-Description:	POWER-systems specific performance monitoring events
-
-		A collection of performance monitoring events that may be
-		supported by the POWER CPU. These events can be monitored
-		using the 'perf(1)' tool.
-
-		These events may not be supported by other CPUs.
-
-		The contents of each file would look like:
-
-			event=0xNNNN
-
-		where 'N' is a hex digit and the number '0xNNNN' shows the
-		"raw code" for the perf event identified by the file's
-		"basename".
-
-		Further, multiple terms like 'event=0xNNNN' can be specified
-		and separated with comma. All available terms are defined in
-		the /sys/bus/event_source/devices/<dev>/format file.
-
 What: /sys/bus/event_source/devices/<pmu>/events/<event>
