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.
