perfcounters: fix a few minor cleanliness issues
This fixes three issues noticed by Arnd Bergmann:
- Add #ifdef __KERNEL__ and move some things around in perf_counter.h
to make sure only the bits that userspace needs are exported to
userspace.
- Use __u64, __s64, __u32 types in the structs exported to userspace
rather than u64, s64, u32.
- Make the sys_perf_counter_open syscall available to the SPUs on
Cell platforms.
And one issue that I noticed in looking at the code again:
- Wrap the perf_counter_open syscall with SYSCALL_DEFINE4 so we get
the proper handling of int arguments on ppc64 (and some other 64-bit
architectures).
