[PATCH 0/8] powerpc/perf: mpc7450: Event fixes, SIAR sampling and sysfs event names

[Matt Turner <mattst88@gmail.com>]

Patches 1-3 fix the MPC7450 perf driver's event tables against the
manual (MPC7450UM Rev. 5, chapter 11).  The worst is patch 3: an
alternatives row joins three different events, so perf can report the
count of a different event.  In one test it was 374 times the real
count.

Patch 4 fills in the L1 data cache events, patch 5 adds the PMC6 copies
of five L3 events to the alternatives table, and patch 6 adds a format/
directory.

Patch 7 takes sample addresses from SIAR on 32-bit.  When a counter
overflows with interrupts disabled, the interrupted PC is where they
are re-enabled; SIAR is not.

Patch 8 names the events in sysfs.

Tested on an iMac G4 (MPC7448).  The 7448 has no L3, so patch 5 and the
L3 half of patch 8 are untested.
