Subject: [PATCH 12/17] x86/tsc: Remove rdtscl()
Date: Fri, 12 Jun 2015 16:41:46 -0700 [thread overview]
Message-ID: <c460502dd7a2f6d10fe1dc8fcebe958d53c6cef0.1434152192.git.luto@kernel.org> (raw)
In-Reply-To: <cover.1434152192.git.luto@kernel.org>
In-Reply-To: <cover.1434152192.git.luto@kernel.org>
It has no more callers, and it was never a very sensible interface
to begin with. Users of the TSC should either read all 64 bits or
explicitly throw out the high bits.
