Paul Mackerras 6984efb692 perf_counter: powerpc: Fix event alternative code generation on POWER5/5+ ... Commit ef923214 ("perf_counter: powerpc: use u64 for event codes internally") introduced a bug where the return value from function find_alternative_bdecode gets put into a u64 variable and later tested to see if it is < 0. The effect is that we get extra, bogus event code alternatives on POWER5 and POWER5+, leading to error messages such as "oops compute_mmcr failed" being printed and counters not counting properly. This fixes it by using s64 for the return type of find_alternative_bdecode and for the local variable that the caller puts the value in. It also makes the event argument a u64 on POWER5+ for consistency.
