Introduces the TRAP_PERF si_code, and associated siginfo_t field si_perf. These will be used by the perf event subsystem to send signals (if requested) to the task where an event occurred.

Since next-20210420 I have noticed a boot regression on all 32-bit Tegra that we are testing. Bisect is pointing to this commit and reverting this patch and patch 6/10 does resolve the issue.

Interestingly there is no apparent crash, but these systems just appear to hang silently after mounting the rootfs. If anyone has any thoughts let me know!

Thanks Jon
