Subject: [PATCH 2/3] tracing/kprobes: Make Kconfig dependencies generic

From: Heiko Carstens <heiko.carstens@...ibm.com>

KPROBES_EVENT actually depends on the regs and stack access API
(b1cf540f) and not on x86.
So introduce a new config option which architectures can select if
they have the API implemented and switch x86.
