Subject: oprofile: select RING_BUFFER
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d69d59f49763e6bd047c591c6c1f84c8e13da931;p=linux-beck.git

oprofile: select RING_BUFFER

Impact: build fix

OProfile now depends on the ring buffer infrastructure:

 arch/x86/oprofile/built-in.o: In function `oprofile_add_ibs_sample':
 : undefined reference to `ring_buffer_unlock_commit'

Select TRACING and RING_BUFFER when oprofile is enabled.
