X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=ccb0aa03d046ff84492396d2e90b408fa5b24a00;p=users%2Fjedix%2Flinux-maple.git

s390: Support CONFIG_TRACE_MMIO_ACCESS

Enable the functionality of commits
d593d64f043a ("lib: Add register read/write tracing support")
210031971cdd ("asm-generic/io: Add logging support for MMIO accessors").

It only depends on explicit function calls for the tracing.
