  "message": "perf_counter: powerpc: Fix event alternative code generation on POWER5/5+\n\nCommit ef923214 (\"perf_counter: powerpc: use u64 for event\ncodes internally\") introduced a bug where the return value from\nfunction find_alternative_bdecode gets put into a u64 variable\nand later tested to see if it is \u003c 0.  The effect is that we\nget extra, bogus event code alternatives on POWER5 and POWER5+,\nleading to error messages such as \"oops compute_mmcr failed\"\nbeing printed and counters not counting properly.\n\nThis fixes it by using s64 for the return type of\nfind_alternative_bdecode and for the local variable that the\ncaller puts the value in.  It also makes the event argument a\nu64 on POWER5+ for consistency.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Corey Ashford \u003ccjashfor@linux.vnet.ibm.com\u003e\nCc: Marcelo Tosatti \u003cmtosatti@redhat.com\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: John Kacur \u003cjkacur@redhat.com\u003e\nCc: Stephane Eranian \u003ceranian@googlemail.com\u003e\nLKML-Reference: \u003c18982.17586.666132.90983@cargo.ozlabs.ibm.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n",
