Commit 8e3747c1 ("perf_counter: Change data head from u32 to u64") changed the type of 'head' in struct perf_mmap_data from atomic_t to atomic_long_t, but missed converting one use of atomic_read on it to atomic_long_read. The effect of using atomic_read rather than atomic_long_read on powerpc (and other big-endian architectures) is that we get the high half of the 64-bit quantity, resulting in the cmpxchg retry loop in perf_output_begin spinning forever as soon as data->head becomes non-zero. On little-endian architectures such as x86 we would get the low half, resulting in a lockup once data->head becomes greater than 4G. This fixes it by using atomic_long_read rather than atomic_read.

perf top is refreshed every delay_secs the thread runs in such loop: while (sleep(delay_secs)) { print_sym_table(); } At the end of print_sym_table(), poll is used without sleep delay to check if we have something from stdin. It means that this check is done only every delay_secs, which can be higher that 2 secs if the user defined a custom refresh rate. We can drop sleep() here and directly use poll to wait between refresh periods, so that the reaction after the user stops perf top after typing "Enter" is immediate and doesn't suffer from the delay_secs latency. Nb: poll doesn't add any overhead that can parasite perf top measures since it sleeps the entire timeout here.
